EXECUTIVE SUMMARY
The Ontario Ministry of Transportation (MTO) Central Region is planning to undertake improvements to
Highway 400 in the Town of Innisfil and City of Barrie. McIntosh Perry was retained by the MTO under
Assignment No. 2017-E-0030 to conduct a Detail Design and Class Environmental Assessment (Class EA) for the
replacement of the existing Highway 400 Innisfil Beach Road overpass structure (Site 30-210), replacement of
the Highway 400 Barrie-Collingwood Railway overhead structure (Site 30-209), widening of the Innisfil Beach
Road from 2-lanes to 4-lanes and reconfiguration of the Highway 400 Innisfil Beach Road interchange to
accommodate the future 10-lane widening of Highway 400. The project works are being completed under
Group Work Project (GWP) 2493-15-00.
A Transportation Environmental Study Report (TESR) was approved in 2004, and a subsequent TESR Addendum
was approved in 2017, for Highway 400 improvements from Highway 89 to Highway 11. The recommendations
from the TESR (URS, 2004) and TESR Addendum (AECOM, 2017) have been built upon as part of the Detail
Design for the study area specified within.
This Design and Construction Report (DCR) presents the results of the transportation engineering and
environmental assessment study in accordance with the approved environmental planning process for Group
‘B’ undertakings under the MTO’s Class Environmental Assessment for Provincial Transportation Facilities
(MTO, 2000), approved under the Ontario Environmental Assessment Act for provincial transportation projects
of a defined scope and magnitude. This Report has been prepared to document the consultation program,
recommended design details, environmental issues and commitments and construction monitoring
requirements.
The recommended design consists of the following:
• Staged removal of existing superstructure and substructure at both Highway 400 structures;
• Construction of substructure for the full future 10-lane Highway 400 cross-section at both structures;
• Construction of the superstructure will be limited to the interim 6-lane Highway 400 at both structures;
• Re-configuration of Innisfil Beach Road interchange;
• Vertical clearance to Innisfil Beach Road is minimum 5.1 m;
• Innisfil Beach Road cross-section includes 4 lanes plus speed change lanes, and an allowance for a 3.0
m Simcoe County Active Transportation trail;
• Vertical and horizontal clearance to Barrie-Collingwood Railway track in accordance with the Standard
Respecting Railway Clearance Guidelines;
• Installation of snowdrift mitigation measures at specific locations within project limits;
• Non-structural culvert replacements and extensions;
• Drainage improvements including two (2) Stormwater Management Ponds, and
• Roadside safety improvements.
Commitments have been made to protect environmental features with appropriate mitigation measures for
terrestrial and aquatic ecosystems, species at risk, traffic disruptions, and construction staging, among others.

1.0 INTRODUCTION AND BACKGROUND
In 2004, a Preliminary Design Study and associated Transportation Environmental Study Report (TESR) was
undertaken to document the required improvements and widening requirements along 30 km of Highway 400
from 1 km south of Highway 89 northerly to the Highway 400 junction at Highway 11. That study recommended
an ultimate 10-lane cross-section for Highway 400.
In 2014, a subsequent Preliminary Design Study was undertaken to provide an update of the required widening
improvements along the same stretch of Highway 400. The study included a review of the then-present (2013),
short-term (2021), and long-term (2031) transportation planning horizons and examined the transportation
problems, opportunities, and issues relating to the existing Highway 400 interchanges within the study area.
This study reaffirmed the need for widening of the Highway 400 corridor to 10 lanes before the year 2031. An
Addendum to the 2004 TESR was prepared and placed on the mandatory 30-Day Public Review Period, resulting
in an approved plan (AECOM, 2017).
In 2017, the Ministry of Transportation Ontario (MTO) retained McIntosh Perry to conduct Detail Design and
Environmental Assessment study for the replacement of the existing Highway 400 Innisfil Beach Road (IBR)
overpass structure (Site No. 30-210), replacement of the Highway 400 Barrie Collingwood Railway (BCR)
overhead structure (Site No. 30-209), widening of Innisfil Beach Road (IBR) from 2-lanes to 4-lanes, and
reconfiguration of the Highway 400 IBR interchange to accommodate the future Highway 400 widening, in the
Town of Innisfil (see Figure 1). The Detail Design is a continuation of the recommendations made during the
Preliminary Design Study.
This Design and Construction Report (DCR) presents the results of the transportation engineering and
environmental assessment study in accordance with the approved environmental planning process for Group
‘B’ undertakings under the MTO’s Class Environmental Assessment (Class EA) for Provincial Transportation
Facilities (MTO, 2000), which has been approved under the Ontario Environmental Assessment Act (OEAA) for
provincial transportation projects of a defined scope and magnitude. This DCR has been prepared to document
the consultation program, recommended design details, environmental issues and commitments and
construction monitoring requirements.
Study Area
The IBR overpass structure is located 9.6 km north of the Highway 400 and Highway 89 interchange and carries
three (3) through lanes and one (1) speed change lane of Highway 400 traffic in each direction over the IBR.
The Highway 400 BCR overpass structure is located 10.2 km north of the Highway 400 and Highway 89
interchange and carries three (3) through lanes of Highway 400 traffic in each direction over a multi-rail track.
BCR line at Highway 400 is active and is operated by Cando Rail Services. There is an existing rail siding (second
track) that begins immediately west of the existing structure and will be within the proposed structure limits.
Vertical and horizontal clearances to the BCR track shall be in accordance with the Standards Respecting
Railway Clearance Guidelines, (Transport Canada, 1992).

The study area extends from 8.2 km north of the Highway 89 Overpass northerly for 3.3 km (Figure 1). The
project limits are confined to the highway right-of-way (ROW), directly adjacent lands.

Overview of the Environmental Assessment Process
The planning and design of MTO provincial transportation projects follow an approved Provincial Class EA
process that has been in place and updated regularly since 1979. The MTO Class EA parent document, Class
Environmental Assessment for Provincial Transportation Facilities, was approved under the Environmental
Assessment Act in the fall of 1999 (revised, July 14, 2000). This process is a principal-based approach rather
than prescriptive in nature. This means that the Class EA defines what must be achieved, rather than defining
how it should be done.
Design and Construction Report Highway 400 Structures, Town of Innisfil G.W.P 2493-15-00
3
The MTO Class EA planning process classifies projects into activity ‘groups’ with a primary focus on consultation,
environmental documentation, and opportunities for ‘bump-up’ to a formal Environmental Assessment. The
groups are as follows:
• Group A: projects that are new facilities;
• Group B: projects that are major improvements to existing facilities;
• Group C: projects that are minor improvements to existing facilities, and
• Group D: projects that involve operation, maintenance, administration, and miscellaneous work for
provincial transportation facilities.
The Class EA outlines principles and processes that must be followed for applicable projects, including
consultation, development and evaluation of alternatives, and documentation. Public participation and
consultation with property owners and other interested parties is a significant element of the decision-making
process. The commitments to mitigate potential environmental impacts of the project work were made
available to external agencies and stakeholders through the public consultation process.
1.2.1 Impact Assessment Act
On August 28, 2019 the Impact Assessment Act (IAA) replaced the former Canadian Environmental Assessment
Act (CEEA), 2012. The projects and activities that are subject to the IAA are very similar to those that were
subject to environmental assessment under the CEAA, 2012. However, some changes have been made to the
“Project List”, such as new thresholds or projects have been introduced or increased. Under the IAA, only those
projects designated by the Physical Activities Regulations or designated by the Minister of Environment on a
discretionary basis may be subject to federal environmental assessment.
It has been determined that this project does not include physical activities identified on the list and is therefore
not subject to the IAA process.

2.0 CONSULTATION
Consultation is a fundamental component of the Class EA process. Consultation was ongoing throughout the
planning of the project in conjunction with the transportation, engineering and environmental protection
principles. It is essential for the success of Class EA studies that the consultation program be fully transparent,
open and inclusive; all public / stakeholder communication must be clear, timely and accessible to all.
The Consultation Program was developed in collaboration with the MTO and meets or exceeds the mandatory
requirement of the MTO Class EA for a Group ‘B’ project. The primary objective of the consultation program
was to keep stakeholders informed throughout the study and encourage comments using effective
consultation methods. Opportunities were provided throughout the study for interested agencies, stakeholder
groups, and individuals to provide input and obtain information about the study.
The consultation program for this study included the following:
• Maintenance of an external agency/stakeholder contact list and property owner/interested public
contact list provided by MTO from the preliminary design process;
• Preparation and publication of Ontario Government Notices (OGNs), including:
o Notice of Study Commencement, and
o Notice of Submission of Design Construction Report and 30-day Public Review Period.
• Preparation and distribution of notification letters to external agency/stakeholders and property
owner/interested public contacts;
• Development and maintenance of a project website;
• Ongoing communication, negotiation, and consultation with municipalities, agencies, stakeholders,
property owners and local businesses, as required;
• Consultation with potentially interested Indigenous Communities,
• Stakeholder meetings with affected agencies and stakeholders, and
• Summary of the consultation process in the environmental project documentation.
Project Contact List
An external Contact List of potentially interested stakeholder groups and individuals used during the
Preliminary Design Study was provided by MTO and maintained throughout this study; updated for
completeness and accuracy as required. This list included federal and provincial government agencies and
ministries, municipal staff and elected officials, Members of Provincial Parliament (MPP), Indigenous
Communities, emergency services, utility companies, public interest groups, businesses, and property
owners/tenants who may be directly or indirectly affected by the project. The full contact list used for this
project can be found in Appendix A.
Notice of Study Commencement
At the onset of the project a Notice of Study Commencement was produced, which included a brief background
of the Highway 400 transportation studies, as well as the subject study and Class EA process. Notifications were
distributed as follows:

Stakeholder Group
Comments Received How It Was Addressed / Response Sent
Public Comments: Your two proposals make sense. Firstly, the Innisfil Beach Road off ramp needs to be updated and secondly, the overpass just to the north needs to be made better so that icing in the winter is not such an issue.
Comments noted.
Public 1) Stakeholder spoke with MP PM and informed her that they were told by a friend that the CN bridge was no longer used for rail traffic and inquired as to why it was being replaced.
2) The stakeholder was curious as to why the project was happening.
3) The Stakeholder asked if the ramps at IBR would be impacted during construction.
1) MP PM informed the stakeholder that the rail was actively operated and owned by the City of Barrie.
2) MP PM indicated that the bridges are at the end of their functional life and require replacement.
3) MP PM advised that there would likely be temporary impacts on the ramps during construction but that the project had not progressed to the point where they could be quantified.
The stakeholder was satisfied with the phone call, and no further response was required.
Public A stakeholder expressed concerns regarding snowmobile passage at the BCR Bridge (Site 30-209), as this is the only means of safe passage across Highway 400. The stakeholder advised that they would hope consideration will be given to alternate safe passage for snowmobilers across Highway 400 during construction. Additionally, the stakeholder suggested that the project team contact the Ontario Federation of Snowmobile Clubs for their input as well.
The project team advised that the Barrie-Collingwood Railway Bridge is proposed for replacement, and therefore it is expected that most aspects will remain the same or be similar to the existing conditions.
Additionally, the project team advised that local snowmobile clubs have been included as part of the consultation project for this project.
Public The stakeholder requested information related to the new bridge and interchange design and asked for the design team to consider accommodating long commercial vehicles (LVCs).
The stakeholder was advised that the final design of the reconstruction of the existing Innisfil Beach Road interchange at Highway 400 will accommodate LCVs. The project team noted that the project limits do not include any work along Industrial Park Road.
Public Stakeholder called the MP PM to convey that they were surprised the BCR Bridge was being replaced. They felt that the rail line is almost
The project team considered the Stakeholder’s comments during design; however, MTO direction was provided to replace the bridge as planned.

defunct. The stakeholder was concerned about the cost to replace the bridge in comparison to the purpose it serves, indicating it was not a good use of tax payer’s money. The stakeholder believes that taxpayers are paying a lot of money for a rail line and the MTO should review cheaper ways to allow rail lines to service industrial areas rather than spending millions on replacing the bridge. The stakeholder suggested constructing a turnout east of Highway 400.
Hydro One Networks
Advised that in their initial review, they confirmed that there are no Hydro One Transmission and Distribution Facilities within the subject area.
They advised that this is only based on current information and that no further consultation with Hydro One Networks Inc. is required if no changes are made.
No response was required.
Lake Simcoe Region Conservation Authority
Requested an electronic copy of the 2017 Class Environmental Assessment and Preliminary Design Study Update.
Asked that they receive a hard copy of the DCR upon its completion.
LSRCA further indicated that this project does not trigger “major development” under the definition of the Lake Simcoe Protection Plan so does not trigger LSPP 4.8-DP or LSPP 6.40-DP and therefore a water balance assessment and review by a hydrogeologist is not required.
Link to website (TESR) provided.
LSRCA is included in the project Contact List and will be informed of when the DCR becomes available for the 30-day public review.
Noted.
County of Simcoe Paramedic Services
No concerns at this point. The County of Simcoe Paramedic Services was included in the Stakeholder Information Meeting to discuss further.
Chippewas of Rama First Nation
Advised that Chippewas of Rama First Nation had no comments or concerns regarding the project but wanted to be included in the project consultation. Additionally, they would like to receive the final report of the detail design as well as the archaeological report.
Chippewas of Rama First Nation is included in the project Contact List and will be informed of when the DCR becomes available for the 30-day public review. The Archaeological Report is an appendix of the DCR.

Comments Received How It Was Addressed / Response Sent
Scugog First Nation
The project lies within the Treaty #18 area, of which we at Mississaugas of Scugog Island are not a signatory, and therefore we will defer to Rama, Beausoleil and Georgina Island First Nations.
No response required.
Aurora Ontario Provincial Police
The OPP provided several suggestions from the perspective of both policing and road safety, including:
o Regular consultation with emergency services during the project to afford the opportunity to give feedback on specific policing and roadside safety concerns;
o Police can assist with providing input such as localized police issues as well as information regarding collisions;
o Construction zone design includes space to be implemented in assisting with the passage of emergency service vehicles during significant incidents in or near the construction area when traffic comes to a halt;
o The creation of safe enforcement zones to assist with reducing speeds in the construction zone;
o Ensure adequate shoulder space during winter months both for snow removal and safe space for vehicles that may break down;
o Ensure adequate signage of the construction zone to supplement police enforcement and increase driver awareness within the construction zone;
o Upon completion of the project, considerations for safe static enforcement zones.
No response was required at the time this letter was received. Aurora OPP was sent the Stakeholder Information Meeting Invitation to provide an opportunity for discussion and coordination.

Stakeholder Information Meetings
The Project Team hosted a Stakeholder Information Meeting (SIM) to disseminate information related to the
proposed project work and discuss potential impacts that the proposed traffic management may cause to the
travelling public during construction. Information gathered during the SIMs were used during the decision-
making process and preparation of mitigation measures. The following sections summarize the SIMs.
2.3.1 Agency Meeting
An Agency SIM invite was sent on March 21, 2019 to emergency services (OPP, police departments, fire
departments and ambulance service provides), student transportation consortiums and County of Simcoe,
Town of Innisfil and City of Barrie engineering departments. SIM invitation and meeting minutes can be found
in Appendix A.
The SIM was held on April 3, 2019 at the South Innisfil Banquet Hall (Lefroy) to provide details regarding the
project, including anticipated temporary ramp and road closures. Attendees at the SIM were as follows:
• Sherly Sutton – South Simcoe Police • Nanda Kandiah – MTO, P&D PM
• Derek Wilson – Innisfil Fire & Rescue • Susan Sieradzki – MTO, Environmental
• Brett Gratrix – City of Barrie • Les Dzbik – MTO, Traffic
• Kate Fitzgerald – City of Barrie • Laura Donaldson – MP, PM & Bridge
• Carolina Cautillo – Town of Innisfil • Curtis Stewart – MP, Asst PM & Bridge
• Jeremy Nyenhuis – Town of Innisfil • Nathan Farrell – MP, Environmental
• Greg McGrath – County of Simcoe
Table 2 summarizes comments and discussions held during the SIM.
Concern Response
City of Barrie (COB) noted that a short-term closure
would be acceptable and preferred compared to
longer-term traffic disruptions. COB inquired whether
there are additional closures expected beyond the
short-term closure.
MP noted that short-term closures are required for tie-
ins of elevations. COB agreed that additional detours
might be able to provide help to distribute the detour
traffic. MP agreed to work with COB to identify these
detours.
Post Meeting Note: There will be one official signed
detour for each closed turning movement (Hwy 89 to
south, Essa to North), 5th and 10th Sideroads to east
and west.

Concern Response
No additional detours will be included, but expectation
that local traffic may use alternate routes given their
knowledge of the road network.
COB noted that the construction of IBR should not be
delayed due to the potential overlap with the timing of
McKay interchange construction. It was pointed out
that the short-term closure would have minimal impact
on the McKay project.
MTO & COB agreed to work together to ensure McKay
Road crossing over Highway 400 will have no
restrictions on traffic flow during the full closure of
Innisfil Beach Road.
Post Meeting Note: MTO project proceeding as planned
regardless of McKay Road progress.

N, W-S ramps), while detours would be provided for
closed movements.
Innisfil Fire & Rescue (IFR) inquired whether the IBR
closure would still allow emergency vehicles to pass as
needed
MP noted that due to extensive grading requirements,
emergency services will not. Emergency service
providers agreed to review their coverage as it relates to
the closure.
SSP noted that they do not cover the highway, so Ontario
Provincial Police (OPP) must be contacted directly.
MP to follow-up with OPP.
Post Meeting Note: MP followed up with OPP. OPP had
no concerns.
IFR Noted that MP should contact the Barrie Fire Chief,
Cory Mainprize.
MP agreed to contact Barrie Fire Chief.
Post Meeting Note: MP contacted Barrie Fire Chief – No
comments.
SSP inquired about the impacts of the construction
occurring at Highway 400/ Highway 89 interchange.
MTO noted that all lanes of Highway 89 are maintained
during construction, so it is not anticipated that this
construction will have any impacts on the detoured
traffic.
IFR were concerned with ramp closures and access to
Highway 400.
Advanced notice to Barrie and IFR is required to alter
coverage of Highway 400 during ramp closures.
COB discussed permitting requirements with MP for
work adjacent to the tracks.
MP to liaise with COB regarding traffic control/flagging
at the crossing during construction activities and provide
a construction staging/sequence plan to the COB for
replacement of the railway structure.

2.3.2 Private Stakeholder Meeting
The MTO Project Team met with a private stakeholder on August 15, 2019. Various topics were discussed
including: sound, light spillage, construction equipment storage and timing. Construction Operational
Constraints have been added to the Contract Package to address relevant issues.
Notice of Submission – Design Construction Report
On September 17, 2020, Notice of Submission – Design Construction Report notification letters were
distributed to the project mailing list. The letters contained information about the detail design for the bridge
replacements and interchange and Highway 400 reconstruction assignment and notified recipients of this DCR
being available for a 30-day public review period. In addition, one (1) OGN was placed in the Innisfil Journal on
September 17, 2020.
Notice of Submission – Design Construction Report letters were distributed by the MTO to the local Member
of Provincial Parliament and Indigenous Communities with an interest in the study area on September 17, 2020.
Notice of Submission materials, including example letters, contact list, and advertisements, can be found in
Appendix A.
2.4.1 Enhanced Covid-19 Consultation
Due to challenges and restrictions associated with Covid-19, consultation efforts have been enhanced to allow
appropriate project review opportunity. To avoid handling of hard copy reports and encourage social distancing
efforts, the DCR is not being placed in public locations for review, and instead will be available to stakeholders
online. Additionally, as many Indigenous Communities have closed their offices due to Covid-19, and are now
working remotely, extra steps are being taken to provide a suitable opportunity for Indigenous Communities
to participate in the review of the DCR, by distributing the Notice of Submission by both letter mail and email.

3.0 DETAILED DESCRIPTION OF THE RECOMMENDED DESIGN
The purpose of this section is to provide a summary of the major features of the detail design and construction
staging. Emphasis on the environmental protection/mitigation and environmental monitoring are integral
components of the detail design, which are incorporated into the Contract Documents that the Contractor is
required to follow. Drawings of the Recommended Design are included in Appendix B.
As mentioned previously, the IBR structural replacement, BCR structural replacement and IBR interchange
reconstruction are components of a major upgrade of Highway 400, extending from Highway 89 to Highway
11, as outlined in the Preliminary Design Report and TESR (2004, addendum 2017). This Detail Design is a
continuation of the recommendations made during the Preliminary Design Study.
Major Features of the Proposed Work
The new IBR overpass bridge will consist of a 33.74 m single-span structure. The foundation and substructure
will be constructed to accommodate the future 10-lane cross-section; however, the superstructure will be
constructed as two separate bridges to provide the required 3-through lanes on the outermost sides of the
future 10 lane configuration. The overall substructure width will be 68.06 m; a northbound lanes (NBL)
superstructure width of 24.21 m and a southbound lanes (SBL) superstructure width of 24.10 m. The minimum
vertical clearance provided below the structure to IBR is 5.125 m. Cast-in-place semi-continuous abutments
will be constructed on spread footings behind the existing abutments. The General Arrangement drawings are
included in Appendix B.
The new BCR overhead bridge will consist of a 14.6 m single-span structure. The foundation and substructure
will be constructed to accommodate the future 10-lane cross-section; however, the superstructure will be
constructed as two separate bridges to provide the required 3-through lanes on the outermost sides of the
future 10-lane configuration. The overall substructure width will be approximately 75.56 m; a NBL
superstructure width of approximately 22.82 m and a SBL superstructure width of approximately 32.99 m. The
minimum vertical clearance provided is 7.2 m over the rail tracks. Cast-in-place semi-continuous abutments
will be constructed on spread footings. The south abutment will be constructed behind the existing abutment
and the north abutment will be constructed at the same location as the existing north abutment. The General
Arrangement drawings are included in Appendix B.
The Highway 400 Innisfil Beach Road interchange will be reconfigured to accommodate the new structures and
future 10-lane widening. New on-ramps, off-ramps and ramp terminals will be constructed within the new MTO
ROW (Appendix B, New Construction).
Innisfil Beach Road will be widened from 2-lanes to 4-lanes within the interchange (i.e. between ramp
terminals). In addition, the roadway platform will include a 3.5 m side clearance on both sides, a 2.0 m median,
3.0 m north sidewalk and 4.8 m south sidewalk/Multi-Use Pathway (to be installed by Simcoe County at a later
date).

Drainage
In accordance with MTO Standards and Guidelines, the recommended drainage works are summarized as
follows:
• Extension of two Highway 400 existing box culverts to the north and south of IBR;
• Replacement of four culverts within the IBR Interchanged that are impacted by the reconstruction;
• Installation of five additional ramp culverts and one additional culvert on IBR;
• Installation of one culvert under Highway 400 to drain the open median;
• Construction of a wet pond approximately 1 km south of IBR on the west side of Highway 400 within
the MTO ROW;
• Construction of a dry pond within the E-S Ramp;
• Construction of two storage ditches on the east side of Highway 400 north of the BCR structure, and
one storage ditch along IBR in the N-E quadrant of the interchange;
• Placement of sewer systems and curb outlets along Highway 400, such that no deck drains are required
at both bridge locations;
• Implementation of a storm sewer system along IBR; and
• Installation of Rip-Rap pads at pipe outlets where erosion is expected.
Roadside Safety and Signing
All roadside features have been designed to the MTO Roadside Design Manual (2017). Existing barriers and end
treatments will be removed and new guide rail and end treatments meeting current MTO Warrants and
Standards will be placed where required.
Existing signs not impacted by the works will be relocated and/or replaced if their condition requires
replacement within two years of completion of construction, or if any existing signs do not comply with the
Ontario Traffic Manuals. French signing is not required under the French Language Services Act.
Electrical/Illumination
The scope of illumination for Highway 400 IBR Interchange includes the following:
• Conventional partial illumination at Hwy 400 IBR interchange decision points will be provided by
utilizing LED fixtures.
• Intersection partial illumination by utilizing LED fixtures will be provided at Hwy 400 IBR Interchange
ramp terminal intersections.
• Temporary illumination will be provided as required at ramp terminal intersections.
Entrances
An existing right-in only entrance in the southeast quadrant servicing a gas station and Tim Hortons will be
reinstated to accommodate the widening on Innisfil Beach Road.
Design and Construction Report Highway 400 Structures, Town of Innisfil
G.W.P 2493-15-00 MTO Assignment No. 2017-E-003
14
All construction activities will be carried out in such a manner that access to side roads, driveways, and
commercial/private entrances will be maintained at all times.
Intersections
The following intersections will be modified as required to accommodate the widening of Innisfil Beach Road
and the future widening of Highway 400:
• S-E/W Ramp Terminal at Innisfil Beach Road, and
• N-E/W Ramp Terminal at Innisfil Beach Road
All turning movements at the ramp terminals will accommodate A-Train long commercial vehicles (LCV).
Active Transportation Infrastructure
A minimum 3.0 m wide area will be provided along the south side of IBR within the limits of the IBR widening
being completed under this project to accommodate a future Simcoe County active transportation trail. The
3.0 m area has bee designed in accordance with the MTO Bikeway Design Manual (2014) to allow for the future
trail to be implemented accordingly.
Snow Drift Mitigation
New snow drift mitigation measures will be installed along the western perimeter of the new MTO ROW. The
new snow drift mitigation measures include 1.2 m snow fence in combination with strategically selected
landscape plantings, as illustrated in Appendix B.
Utilities and Pipe Lines
The following utilities requiring relocation are located within or adjacent to the Highway 400 right-of-way:
• Bell Canada;
• Enbridge;
• InnPower;
• Rogers, and
• InnServices (water).
Construction Staging
Highway 400 staging will be completed such that 6-lanes will remain open at all times, excluding night-time
single lane closures required to complete temporary pavement transitions and shifting traffic. Lane widths will
be reduced to 3.5 m along both Highway 400 and Innisfil Beach Road during construction to facilitate the
staging sequence relating to the structure replacement.
Full closure of IBR will be required for 4-6 weeks to complete the interim grade lowering. Some turning
movements, including E-S and W-N, will be restricted due to the closures. Signed detours will be provided. Full
closure of the S-E/W ramp will be required for a period of 2-3 weeks to facilitate the construction of the new
S-E/W ramp. Signed detours will be provided.

4.0 ENVIRONMENTAL CONDITIONS, ISSUES AND COMMITMENTS
This section presents an overview of the existing conditions, environmental concerns and potential impacts to
the natural, socio-economic and cultural environments associated with the project. To mitigate the potential
impacts on the natural, socio-economic, and cultural environments, the Contractor is responsible for
implementing the requirements of referenced Special Provisions (SP), Non-Standard Special Provisions (NSSP),
and Ontario Provincial Standard Specifications (OPSS) prescribed in the Contract Documents. In general, the
Contractor is responsible for the protection of people, property and the natural environment from adverse
impacts and damage that may result from this work, in accordance with Operational Constraint –
Environmental Protection Requirements – General.
Natural Environment
During preliminary design, the MTO’s service provider conducted an Existing Environmental Conditions study
(FRi Ecological Services, 2015) and Natural Heritage Impact Assessment study (FRi Ecological Services, 2017) for
the larger study corridor of Highway 400 from Highway 89 to Highway 11.
McIntosh Perry conducted several field investigations during the 2018 and 2019 field seasons, collecting data
related to existing natural environmental conditions through the study area. The investigations included
identification of the following, where applicable:
• Aquatic habitat and fish communities;
• Existing vegetation communities;
• Existing wetland areas;
• Observations of SAR and their habitat (including suitable habitat);
• Resident or migrant bird and wildlife species;
• Wildlife corridors;
• Significant habitat areas or vegetation communities, and
• Current land uses surrounding the study area.
4.1.1 Aquatic Habitat and Fish Communities
One (1) fish-bearing watercourse was identified to be associated with the study area; a tributary of Lover’s
Creek, Culvert 58, at STN 18+398. The tributary of Lover’s Creek flows eastward through Culvert 58 under
Highway 400, towards Lover’s Creek and ultimately outlets to Lake Simcoe. Culvert 58 will require a 14.5 m
extension on the west side of Highway 400 to allow for the future widening of Highway 400. To facilitate the
extension of the culvert, a realignment of the watercourse is required.
The project works do not represent routine MTO works and the MTO Best Management Practices for Fisheries
Draft (DFO, 2018a) are not applicable. As potential habitat for cool-water and warm-water baitfish species was
identified in the tributary of Lover’s Creek upstream and downstream of Culvert 58, a detailed impact
assessment of aquatic effects was completed for the Culvert (Culvert 58) extension. This information is
Design and Construction Report Highway 400 Structures, Town of Innisfil
G.W.P 2493-15-00 MTO Assignment No. 2017-E-003

ultimately required to ensure a defensible determination as to the likelihood of the project causing the death
of fish or harmful alteration, disruption, or destruction (HADD) of fish habitat.
Standard mitigation measures will be implemented during construction including, construction timing windows
(July 16 to September 30), erosion and sediment control measures, designed specifically for this project, and
rehabilitation of disturbed areas within and adjacent to Culvert 58.
In addition, based on hydraulic modelling of existing and proposed flows through Culvert 58, the installation of
22 baffles spaced at 2 m intervals throughout the entirety of the culvert is proposed as a means to enable fish
passage through the culvert under conditions of a 1 in 2-year storm event.
There is also be enhancement opportunity at the culvert located approximately 20 m south of the outlet of
Culvert 58 that will be addressed as part of this project. The installation of rip rap at the median drain outlet to
attenuate high intensity discharges will reduce erosion and sediment inputs to the watercourse. These
measures will be of benefit to downstream fish habitat within the Lover’s Creek watershed.
Full details related to aquatic habitat and fish communities can be found in the Fish and Fish Habitat Existing
Conditions and Impact Assessment Report, prepared by McIntosh Perry, dated June 12, 2020.
To ensure compliance under the Fisheries Act, this project was submitted to DFO for review (i.e., as a result of
the proposed destruction of fish habitat).
The Fish and Fish Habitat Protection Program (the Program) of DFO provide a response to the Request for
Review form and associated documents for the proposed culvert expansion in Lover’s Creek. DFO’s Letter of
Advice (LOA) noted that the Program is of the view that the proposed work will not require an authorization
under the Fisheries Act or the Species at Risk Act, provided that all recommended mitigation measures are
incorporated into the Contract. To avoid and mitigate the potential for prohibited effects to fish and fish
habitat, DFO recommended implementing the following measures:
• Plan in-water works, undertakings and activities to respect timing windows to protect fish, including
their eggs, juveniles, spawning adults and/or the organisms upon which they feed and migrate
o No in-water works between October 1st – July 15th.
• Capture, relocate and monitor for fish trapped within isolated, enclosed, or dewatered areas
• Screen intake pipes to prevent entrainment or impingement of fish
o Use the code of practice for water intake screens
• Limit impacts on riparian vegetation to those approved for the work, undertaking or activity
o Re-vegetate the disturbed area with native species suitable for the site
• Salvage, reinstate or match habitat structure (e.g., large wood debris, boulders, instream aquatic
vegetation/substrate) to its initial state
o Replace/restore any other disturbed habitat features and remediate any areas impacted by the
work, undertaking or activity
• Limit the duration of in-water works, undertakings and activities so that it does not diminish the ability
of fish to carry out one or more of their life processes (spawning, rearing, feeding, migrating)
Design and Construction Report Highway 400 Structures, Town of Innisfil
G.W.P 2493-15-00 MTO Assignment No. 2017-E-003
17
• Develop and implement and erosion and sediment control plan to avoid the introduction of sediment
into any waterbody during all phases of the work, undertaking or activity
o Regularly monitor the watercourse for signs of sedimentation during all phases of the work,
undertaking or activity and take corrective action
o Schedule work to avoid wet, windy and rainy periods (and heed weather advisories) that may
result in high flow volumes and/or increase erosion and sedimentation
• Develop and implement a response plan to avoid a spill of deleterious substances
o Keep an emergency spill kit on site during the work, undertaking or activity
o Report any spills of sewage, oil, fuel or other deleterious material, whether near or directly into
a waterbody
• Embed culverts to ensure fish passage through the watercourse is maintained
All recommended mitigation measures outlined in DFO’s LOA have been incorporated into the Contract
Documents for implementation during construction of this project, and a copy of the LOA shall be kept on site
while the work is in progress.
4.1.2 Vegetation and Vegetation Communities
The study area vegetation is dominated by agricultural fields and sparse cultural vegetation. The land adjacent
to the southwest of the interchange consists of an agricultural crop field, treed fencerows and one small (1 ha)
deciduous woodlot. The land west of the southbound off-ramp consists of an agricultural crop field and treed
fencerows. A graminoid field is present north of the southbound off-ramp, which continues along the west side
of the Highway to the BCR Overhead structure. The interchange loops consist of a mix of cultural meadow,
manicured lawn and cultural thickets containing sparse woody vegetation. The southwest and southeast loops
of the interchange were under construction during the 2018 field investigations. Commercial property is
present east of Highway 400 between the Innisfil Beach Road interchange and the BCR Overhead structure,
containing manicured lawn and sparse woody vegetation. Commercial and residential properties are present
directly southwest of the interchange. No rare vegetation communities or vegetation species at risk (SAR) were
observed in association with the study area.
Lands adjacent to the Highway 400 travel corridor consist of a variety of vegetative communities. Based on
Ecological Land Classification (ELC) vegetation types, vegetation communities were identified through field
review and satellite image interpretation within, and adjacent to, the study area. Figure 2 illustrates the
vegetation communities and ELC vegetation types identified within the study area. For a complete list of
vegetation observed within the study area, refer to the Terrestrial Ecosystems Existing Conditions and Impact
Assessment Report, GWP 2493-15-00, prepared by McIntosh Perry, dated December 13, 2019.
The project will result in the removal of approximately 18,686 m2 of trees/vegetation to accommodate
construction activities, see Appendix B ‘Removals’. The study area is heavily influenced by human activities and
contains a range of native and non-native herbaceous vegetation species. No impacts on SAR plant species are
anticipated, as none were identified. A Landscape Plantings plan has been developed for the stabilization of
disturbed areas during construction, as discussed in Section 4.1.4 below.

4.1.2.1 Invasive and Noxious Plant Species
During the 2018/2019 field investigations, no species classified as ‘Invasive Plant Species’ under the Invasive
Species Act (2015) were observed within the study area. However, one (1) ‘Noxious Species’, as defined by the
Weed Control Act, 1990, was identified: Canada thistle (Cirsium arvense). There were no concentrated areas or
‘stands’ of this species observed within the study area, and abundance was low; therefore, NSSP ENVR0011
Invasive and Noxious Vegetation Spraying/Invasive and Noxious Vegetation Cutting, will not be included in the
contract package.

4.1.3 Erosion and Sediment Control
McIntosh Perry prepared an Erosion and Sediment Control Plan (ESCP) to satisfy the requirements set out in
Approach 2 of the MTO’s Environmental Guide for Erosion and Sediment Control During Construction of
Highway Projects (ESC Guide). The ESCP consists of three components:
1) ESC Non-Standard Special Provisions (NSSPs);
2) A series of site plans illustrating and describing mitigation measures to be undertaken during all phases
of the project (Site Drawings), and
3) A Technical Memo that is a record of the information and design criteria used in developing the ESC
strategy for the highway project.
The purpose of an ESCP is to minimize erosion potential, apply erosion control measures to prevent
mobilization of sediment, and apply sediment control measures to prevent off-site sediment release in the
event of sediment mobilization. ESC measures may include, but are not limited to, light-duty silt fence barriers,
light-duty fibre roll barriers and fibre roll flow check dams. In addition, temporary erosion control measures
will be applied as per Special Provision No. ENVR0005. Alternate methods may be accepted provided they meet
the industry standard and are approved by the Contract Administrator (and by ESC Design Consultant where
determined to be required by the Contract Administrator). It should be noted that the ESCP constitutes the
minimum requirements; however, the Contractor is required to adaptively manage erosion and sediment
control from construction activities as needed.
Details of the ESCP can be found in the Erosion and Sediment Control Plan Technical Memo, prepared by
McIntosh Perry, dated June 26, 2020 and Appendix B, Construction Staging.
4.1.4 Landscape Plantings
Developed in conjunction with the highway design and staging plans, a Landscape Planting Plan aims to address
the need for stabilization of disturbed areas due to construction through revegetation. CSW Landscape
Architects Ltd. (CSW) prepared a series of landscape plantings that are designed to integrate infrastructure
needs, such as stormwater management ponds, with landscape works to minimise the environmental and
visual impact of construction. In addition, landscape plantings incorporate recommendations made for snow
drift mitigation (Appendix B, Landscape Plans).
4.1.5 Wetland Communities
Lover’s Creek Swamp is a provincially significant wetland (PSW) located 200 m east of the study area. Lover’s
Creek Swamp PSW is over 160 ha and is comprised of mostly mixed swamp, Thicket Swamp, coniferous swamp,
deciduous swamp, meadow marsh and shallow marsh (LSRCA, 2012).
Mitigation measures to control the release of water and/or sediment during construction will prevent negative
impacts to the identified PSW.

4.1.6 Wildlife
Wildlife observed during the 2018/2019 field investigations were characteristic of the Lake Simcoe-Rideau
Ecoregion. Observations of thirty (30) bird species, two (2) mammals, and one (1) insect were documented
during the field investigations through signs, visual observations and vocalizations.
No significant wildlife habitat is known to occur within or directly adjacent to the study area based on a review
of background information and field investigations. As such, it is not anticipated that the proposed project
works will result in impacts on the function of significant wildlife habitat. However, the lands associated with
the study area provide several ecological functions including, but are not necessarily limited to:
• Nesting habitat for several species of migratory birds;
• Local travel corridors for small wildlife along fencerows, and
• Habitat for endangered and threatened species (Eastern Meadowlark), refer to Section 4.1.7, below.
4.1.6.1 Migratory Birds
Migratory birds are known to nest in vegetation present within the study area, including areas planned for
permanent removal. The period when a bird is actively nesting is considered its most critical life stage, as many
species are highly dependant on habitat around their nest sites to supply food for nestlings and to conceal their
nests, eggs, and young. As detailed information on the bird species (migratory birds, provincially protected
birds, and birds not afforded protection) is readily available for the study area, a detailed nesting window has
been provided for this location. The Bird Studies Canada Nesting Calendar Query Tool (OBBA, 2006) was used
to determine the most appropriate nesting period based on the individual bird species known to utilize the
study area for the purpose of nesting. The core nesting period for birds within the study area is approximately
April 1 to September 15 of any year (i.e., the period when most birds are anticipated to be actively nesting).
A total of sixteen (16) active Cliff Swallow nests were observed on the BCR overhead structure during the field
investigations on June 11, 2018. During the 2019 field investigations, the species remained present within the
general study area; however, no active nests of the species were observed on the structure. It was confirmed
that the birds did not nest on the structure during the 2019 nesting season.
The Migratory Birds Convention Act (1994) (MBCA) protects migratory birds as well as their nests and eggs
across Canada. Due to the history of Cliff Swallows utilizing the BCR overhead structure, bird exclusionary
measures (e.g. tarping) shall be installed on the existing bridge prior to May 15th and must be maintained until
August 15th of any year. If construction on the existing structure is completed outside the bird nesting window,
exclusionary measures are not required.
4.1.7 Species At Risk
Three (3) SAR were observed within the study area during the 2018/2019 field investigations. These species
include the Barn Swallow (Hirundo rustica), Monarch (Danaus plexippus), and Eastern Meadowlark (Sturnella
magna).
Design and Construction Report Highway 400 Structures, Town of Innisfil
G.W.P 2493-15-00 MTO Assignment No. 2017-E-003
22
4.1.7.1 Barn Swallows
Of the SAR species observed during the 2018/2019 field investigations, the Barn Swallow was not observed
nesting in association with any of the existing infrastructure (i.e., bridges, underpasses, culverts, etc.) or
vegetation within the study area. Barn Swallows were observed foraging over the area of suitable Eastern
Meadowlark habitat. Several suitable structures (i.e., barns) are present within the general study area, which
is assumed to be where the Barn Swallows were nesting. No suitable structures or confirmed nest sites are
known to exist within 200 m of any proposed construction (i.e., habitat will be disturbed) which is the maximum
area that is protected for this species as per the General Habitat Description for Barn Swallow. The Barn
Swallow may indirectly benefit from mitigation associated with the Eastern Meadowlark habitat outlined
below.
4.1.7.2 Monarch
The Monarch was observed within the study area during the 2019 field investigations. This species relies heavily
on milkweed (Asclepias spp.) for several life processes. Common milkweed was identified within the study area.
The Monarch is listed as ‘Special Concern’ under the ESA and SARA and does not receive habitat protection.
Seed mix used for revegetating disturbed areas will contain native species (i.e., Old Field Mix as per OPSS 804)
that Monarch uses for a variety of life processes, which will improve monarch habitat in the study area.
4.1.7.3 Eastern Meadowlark
Targeted surveys for grassland avian SAR (i.e. Bobolink, Eastern Meadowlark, Grasshopper Sparrow) were
conducted during three (3) field investigations in 2018. During the June 20, 2018 field investigation, a single
Eastern Meadowlark was heard singing north of the fence line beyond the Highway 400 southbound exit ramp
of the Innisfil Beach Road Interchange. The Eastern Meadowlark is listed as ‘Threatened’ under the ESA and
the SARA. Though this individual was observed during the June 20, 2018 survey, no observations of the Eastern
Meadowlark were made during the June 11 or June 26, 2018 field investigations. During the surveys the existing
habitat remained suitable as habitat (i.e. un-mowed etc.). While the surveys were completed at the appropriate
time (i.e. between 5:00 am and 9:00 am each survey, during the species nesting season) the finding of the bird
in the middle survey resulted in inconclusive data in terms of concluding as to whether the area meets the
criteria of “habitat” protected under the ESA (i.e. whether the bird held a territory or not).
Based on the observation, additional targeted surveys were completed during the spring of 2019 to collect
additional information on the presence of Eastern Meadowlarks and their habitat within the study area. The
first 2019 survey was completed on May 29, 2019. During this survey two (2) individual male Eastern
Meadowlarks and one (1) female Eastern Meadowlark were observed within the area of suitable habtiat
associated with the interchange. During the June 13, 2019 field investigation both male Eastern Meadowlarks
remained on site and two (2) individual female Eastern Meadowlarks were also observed. Based on these
observations, and the 2018 observation, both Category 2 and Category 3 Eastern Meadowlark habitat (as per
the General Habitat Description for Eastern Meadowlark https://www.ontario.ca/page/eastern-meadowlark-
general-habitat-description) is confirmed present within the area of suitable habitat north west of the existing
interchange alignment (Figure 3).

Due to the identified nesting of Eastern Meadowlark adjacent to the interchange, there is the potential for the
project works to impact individual Eastern Meadowlarks (i.e. harm, harassment under the ESA). The Eastern
Meadowlark is generally intolerant of human presence (e.g. worker presence) and often displays agitated
behaviours and may stop feeding young when humans are present. The species typically does not respond
aggressively to human presence (i.e. as do Red-winged Blackbirds) but rather moves away from the perceived
threat and discontinues normal foraging and nesting activities to avoid the perceived threat detecting the nest,
which is located on the ground. The species is capable of habituating to human presence, noise and activity
where they are accustomed to frequently seeing humans. Given observations made during 2018/2019, the
Eastern Meadowlarks nesting within the study area appear accustomed to noise and vehicle traffic (i.e. due to
the close proximity to Highway 400), but do not appear accustomed to human presence. During the 2019 field
investigations all birds present were observed to modify their activities and responded with alarm calls to
observer presence. As such, it is likely that worker presence and ongoing construction activity is likely to result
in impacts to individuals (i.e. harm, harassment).
Based on the Bird Studies Canada Nesting Calendar Query Tool (OBBA, 2006), the core nesting window for the
Eastern Meadowlark within the study area is May 1 to July 30 of any year. This represents the period when the
Eastern Meadowlark is most likely to have a nest with eggs or young. The species begins its nesting cycle (i.e.
territory establishment etc.) earlier typically arriving back on the breeding grounds by April 15. Based on the
project design and associated works, impacts to individual Eastern Meadowlarks are anticipated.
The project has a high potential to result in harm or harassment of individual Eastern Meadowlarks due to the
relatively long timeframe of construction and significant volume of work that must occur within and directly
adjacent to the species and its habitat. Harm and Harassment are not permitted under the provisions of the
MBCA or SARA legislation, which also protect the Eastern Meadowlark wherever it occurs in Canada. The MBCA
does not have habitat provisions (the nest is protected however). Critical Habitat has not been defined for the
Eastern Meadowlark under SARA (currently only the “residence”, which equates to the nest in the case of most
bird species). The habitat of the Eastern Meadowlark is only afforded protection under the provincial ESA and
associated regulations.
Based on planned works within and adjacent to Eastern Meadowlark Habitat, the project is anticipated to result
in the following:
• Permanent destruction of approximately 2.36 ha of Eastern Meadowlark habitat (approximately 1.25
hectares of Category 2 and approximately 1.11 hectares of Category 3 Eastern Meadowlark habitat),
and
• Temporary damage for four (4) years of construction of approximately 4.65 ha of Eastern Meadowlark
habitat to avoid harm/harassment of the species during construction.
Given the proposed interchange works, it is not anticipated that the 2.36 ha or destroyed habitat will be
returned to a suitable state to be used by the Eastern Meadowlark.

25
Under section 23.6 of Ontario Regulation (O. Reg.) 242/08, made under the ESA, the project meets the criteria
for an exemption under the ESA based on size (i.e. under 30 hectares of Eastern Meadowlark Habitat impacted).
As such, the project has been registered with the MECP and the required Eastern Meadowlark Habitat
Management Plan (EMHMP) has been developed for implementation by the MTO. The EMHMP includes
compensation for habitat loss, to be created elsewhere on MTO lands.
4.1.8 Groundwater
During the 2018/2019 field investigations, no evidence of groundwater seeps was identified within the study
area. However, groundwater seepage and stormwater inflow into excavations is expected. Construction
dewatering will be required to ensure that the work areas remain dry. Based on calculations made by McIntosh
Perry it is expected that the typical volume of groundwater and stormwater being pumped per day will be in
excess of 400,000 L/day. Therefore, a Category 3 Permit to Take Water (PTTW) was applied for with the MECP.
Groundwater that seeps into the excavations, as well as any collected stormwater within the excavations, will
be discharged downgradient of the work area as per OPSS 517. It is recommended that the groundwater and
stormwater be directed to a sediment control device installed on a well vegetated area prior to release to the
natural environmental (i.e. the surrounding area). If a sediment control device is used, a minimum of 30 m
setback shall be maintained from any watercourse (i.e. any permanent or intermittent natural or constructed
waterbody such as lakes, ponds, wetlands and watercourses).
A comprehensive water monitoring plan is not considered to be necessary as part of the PTTW because the
water taking will be in stages of a short-term nature and there are no identified nearby shallow groundwater
users.
The study area is located in the South Georgian Bay, Lake Simcoe Region Source Water Protection Area.
Consultation with the LSRCA confirmed that this project does not trigger “major development” under the
definition of the Lake Simcoe Protection Plan so does not trigger LSPP 4.8-DP or LSPP 6.40-DP and therefore a
water balance assessment and review by a hydrogeologist is not required.
4.1.9 Surface Water
Hydrologic and hydraulic analyses were performed for the study area based on design criteria and guidelines
detailed in a variety of MTO and other relevant standards documents. The area within the project limits was
divided into five major areas/outlets, considering roadway separations for the existing, interim and proposed
future drainage patterns. Four of these major areas ultimately drain eastward to Lake Simcoe and one area
ultimately drains westward to the Nottawasaga River. Where these areas outlet from the project limits an
assessment was undertaken to ensure that the post-development peak flows are attenuated to the
corresponding pre-development levels. Stormwater management facilities have been proposed in three of the
five areas to achieve the required reduction in peak flows.
A Drainage and Hydrology Report was prepared by McIntosh Perry (January 13, 2020), which details the
following:
Design and Construction Report Highway 400 Structures, Town of Innisfil
G.W.P 2493-15-00 MTO Assignment No. 2017-E-003
26
• Hydrologic and hydraulic assessment of storm sewers for interim and ultimate drainage conditions
along Highway 400 and IBR;
• Capacity assessments for all ditches and culverts (existing and proposed) within the project limits;
• The design of five (5) stormwater management storage facilities (ponds/storage ditches) to mitigate
runoffs from three (3) major outlets that account for water quality and quantity control; and
• The design of pavement drainage to meet the allowable spread of runoff on the travelled lanes.
Culverts associated with existing, interim and ultimate conditions were hydrologically and hydraulically
assessed. All interim culverts were also analyzed for the ultimate conditions to assess whether they have the
capacity to convey the expected ultimate increases of flow. As a result, the following drainage works were
included in this Contract Package:
• Extension of two Highway 400 existing centreline box culverts to the north and south of IBR;
• Replacement of four culverts within the IBR Interchanged that will be impacted by the reconstruction;
• Installation of five additional ramp culverts and one additional culvert on IBR;
• Installation of one culvert under Highway 400 to drain the open median;
• Construction of a wet pond approximately 1 km south of IBR on the west side of Highway 400 within
the MTO ROW;
• Construction of a dry pond within the E-S Ramp;
• Construction of two storage ditches on the east side of Highway 400 north of the Barrie Collingwood
Rail Structure, and one storage ditch along IBR in the N-E quadrant of the interchange;
• Placement of sewer systems and curb outlets along Highway 400, such that no deck drains are required
at both bridge locations;
• Implementation of a proposed storm sewer system along IBR; and
• Installation of Rip-Rap pads at pipe outlets where erosion is expected.
Socio-Economic Environment
A thorough review of the socio-economic environment within the study area was conducted during detail
design. The existing conditions outlined in the preliminary design report and TESR were examined and are
generally consistent with current conditions. Potential socio-economic impacts of the proposed work to the
study area are restricted to the Highway 400 and Innisfil Beach Road ROW, adjacent land uses, as well as local
road detour routes and staging areas.
The following sections describe the potential impacts to the socio-economic environment associated with the
project works and provide a summary of mitigation measures included in the contract documents.
4.2.1 Land Use
The study area is located within the geographic boundaries of the Town of Innisfil, County of Simcoe; the City
of Barrie border is approximately 2 km north of Innisfil Beach Road. Identified in the Town of Innisfil Official
Plan (November 2018) as ‘Innisfil Heights’, the land surrounding the Highway 400 interchange is zoned to be
an employment hub, with light industry, office and retail businesses. The lands adjacent to the west of Highway
Design and Construction Report Highway 400 Structures, Town of Innisfil
G.W.P 2493-15-00 MTO Assignment No. 2017-E-003
27
400 consist of agriculture lands and the Georgian Downs Racetrack and Casino. Lands to the east of Highway
400 include commercial, light industrial and residential. The IBR Interchange is the primary access for the Town
of Innisfil and also provides access to Lake Simcoe and Innisfil Beach Park. There is an MTO carpool lot to the
northeast of the IBR Interchange.
The BCR overhead structure is utilized by the Barrie-Collingwood Railway (BCRY) which is a short-line railway
operation used for shipping and receiving of industrial products in the City of Barrie and surrounding areas. The
BCRY is owned by the City of Barrie and operated by Cando Rail Services Ltd. Land use surrounding this structure
is industrial/commercial on three sides and agricultural/rural residential on the southwest quadrant. A railway
yard and turnaround area are located adjacent to the west of the BCR overhead structure. The Contractor is
required to adhere to all restrictions and requirements described in Operational Constraint – Work On, Above
or Below Railway Right Of Way.
The Innisfil Cemetery and Mausoleum is located in the northwest limits of the study area, north of Georgian
Downs Racetrack and Casino.
A number of property acquisitions were required for the Highway 400 IBR Interchange improvements and
future widening of Highway 400 to 10-lanes. With the exception of the MTO acquired property, land uses within
the study area will not be impacted due to the project work.
4.2.2 Designated areas
The Thornton-Cookstown Trans Canada Trail commences southwest of Cookstown and terminates in a small
parking lot approximately 600 west of the BCR Overhead structure. The trail is a 15.6 km long former railbed,
now consisting of a shared use trail (walking, cycling, horseback riding, cross country skiing, snowmobiling) that
travels through pastureland, forests and crosses Cookstown Creek six times. The project is not anticipated to
impact the trail or trail users.
4.2.3 Municipal Services and Traffic Operations
Highway 400 is classified as a Rural Freeway Divided and has a posted speed limit of 100 km/h. Within the
project limits the highway has a rural/suburban surrounding with the main traffic generators expected to be
the City of Barrie to the north and the Greater Toronto Area (GTA) to the south. MTO has classified this segment
of Highway 400 as having a ‘Commuter Tourist Recreation’ traffic pattern. Highway 400 at this location varies
from six to eight lanes (three through lanes and one speed change lane for each direction). The ultimate cross
section for Highway 400, as approved in the TESR (URS, 2004) and TESR Addendum (AECOM, 2017) will include
a 10-lane cross section consisting of 4 General Purpose Lanes and 1 High Occupancy Vehicle (HOV) lane in each
direction.
Innisfil Beach Road runs east-west from Simcoe County Road 27 in the west through the Town of Innisfil and
ending at Lake Simcoe. Within the project limits, Innisfil Beach Road has a posted speed limit of 60 km/h and
varies from two to three lanes (one through lane for each direction and one auxiliary lane). The ultimate cross
section for Innisfil Beach Road will be a 4-lane cross section consisting of 2 lanes in each direction, and auxiliary
lanes for the interchange ramps.

G.W.P 2493-15-00 MTO Assignment No. 2017-E-003
28
In order to complete the planned work for this project construction staging is required and has been broken
down into three (3) stages involving eight (8) substages.
Traffic disruptions are anticipated throughout construction, including temporary Highway 400 lane and ramp
closures, long duration shoulder closures, and detours to the adjacent road networks. In addition, Innisfil Beach
Road is expected to be closed at Highway 400 for up to 6 weeks to facilitate a major grade lowering. During
this time detour routes will be communicated to the pubic with signage, as illustrated in Appendix B, Detours.
Impacts associated with traffic disruptions include emergency service response times and an anticipated
increase to municipal road traffic volumes within the vicinity of the project area (i.e., the Town of Innisfil, the
City of Barrie, and the County of Simcoe) and detour route. The detour route has been discussed with the
affected emergency service provides and affected municipalities. The contractor will be required to notify the
potentially impacted municipalities and emergency services a minimum of two weeks in advance of any full
road closures. Additionally, Portable Variable Message Signs (PVMS) will be used to provide up-to-date
information to drivers regarding construction works on Highway 400, and temporary advanced notification
signs will be used to provide drivers with advance notification of ramp closures at the Innisfil Beach Road
interchange.
4.2.4 Construction Noise
Unlike operational traffic noise, the MTO does not establish a quantitative threshold noise level to establish
construction noise impacts. However, in accordance with MTO policy, a Contractor shall strictly adhere to the
Construction Noise Constraints, Special Provision No. 199F33. Construction noise produced by the Contractor’s
operations shall be mitigated as shown in Table 3.
Table 3: Construction Noise Constraints
Constraint Constraint Details
Equipment Maintenance Equipment shall be maintained in an operating condition that
prevents unnecessary noise, including but not limited to non-
defective muffler systems, properly secured components, and the
lubrication of moving parts.
Equipment Operation Idling of equipment shall be restricted to the minimum necessary to
perform the specified work.
Georgian Downs Racetrack The Contractor shall minimize construction noise during days that
racing occurs at the Georgian Downs Racetrack (Saturdays, Sundays
& Tuesdays from June 1st to August 31st).
4.2.5 Air Quality
The MTO has a methodology for assessing local air quality impact, which is set out in the Environmental Guide
for Assessing and Mitigating the Air Quality Impacts and Greenhouse Gas Emissions of Provincial Transportation
Design and Construction Report Highway 400 Structures, Town of Innisfil
G.W.P 2493-15-00 MTO Assignment No. 2017-E-003
29
Projects (AQ Guide) (MTO, 2012). During the preliminary deign study the Highway 400 corridor from Highway
89 to Highway 11 was analyzed under the AQ Guide. The study determined that proposed work at the IBR and
BCR structures would have negligible impacts to air quality and no design changes were recommended.
The project work generally has the potential to create dust due of construction activities. Dust suppressants
will be required to be used by the contractor during construction to ensure dust is kept to a minimum.
4.2.6 Waste & Contamination
McIntosh Perry conducted desktop and field survey to determine the possible presence of the eleven (11)
designated substances identified by Ontario Regulation 490/09 under the Occupational Health and Safety Act,
including:
• Acrylonitrile • Coke Oven Emissions • Mercury
• Arsenic • Ethylene Oxide • Silica
• Asbestos • Isocyanates • Vinyl Chloride
• Benzene • Lead
Where available, documentation such as construction drawings and Ontario Structure Manual – Inspection
Forms, were reviewed to determine the potential for designated substances to be associated with the bridges
slated for replacement. Following documentation review, the bridges were inspected and where accessible
sampling was performed for analytical assessment.
As no painted components were identified on the structures, the collection of paint samples for the analysis of
arsenic, lead and mercury was deemed to be not warranted.
The collection of concrete samples for analysis of asbestos was undertaken at both bridge locations (Sites 30-
209 & 30-210). Asbestos was not detected within the concrete samples submitted for analysis.
While the designated substance benzene was not detected with the preserved wood samples submitted for
analysis, it is assumed to be present throughout the working area in the form of bituminous based products
(asphalt). Additionally, analysis of the submitted wood samples indicated detections of arsenic as well as the
hazardous material chromium.
Silica is also assumed to be present throughout the working area, but not limited to, asphalt, granular materials
and concrete.
Of the remaining ten designated substances, it is assumed that acrylonitrile and vinyl chloride are constituents
of acrylonitrile butadiene styrene (ABS) and polyvinyl chloride (PVC) materials, however once polymerized
these two substances are no longer considered designated substances. The remaining designated substances
(coke oven emissions, ethylene oxide, isocyanates and mercury) are not likely to be encountered in typical
construction or maintenance activities of MTO infrastructure.
Design and Construction Report Highway 400 Structures, Town of Innisfil
G.W.P 2493-15-00 MTO Assignment No. 2017-E-003
30
No other designated substances were identified during the investigations.
Details related to the designated substances survey can be found in the Designated Substances Survey Report,
prepared by McIntosh Perry, dated November 20, 2018.
4.2.7 Utilities
It is the Contractor’s responsibility as ‘Constructor’ under the Occupational Health and Safety Act to coordinate
the activities of all employees and subcontractors and works operation within the contract limits to ensure that
the requirements of the Occupational Health and Safety Act are satisfied.
The Tender documents advise the Contractor that there are existing utilities within the project limits owned by
various utility companies/authorities. It is the Contractor’s responsibility to liaise with appropriate utility
companies/authorities to confirm the exact nature, extent, and number of the existing utilities. The Contractor
shall be responsible for the protection of all utilities during construction operations. The Contractor shall
exercise due care so as to not cause any detrimental effects to these utilities. Any damages to these utilities
shall be immediately reported to the Contract Administrator and the affected utility owner. Any repairs to
damaged utilities shall be the responsibility of the Contractor at no additional cost to MTO.
4.2.8 Snow Drift Assessment
McIntosh Perry retained RWDI to review the snow drift assessment prepared during preliminary design (RWDI,
2016), which provided recommended snow drift mitigation measures to be incorporated into various landscape
and grading design.
As a result, snow drift mitigation measures will consist of a combination of mass plantings (trees, shrubs, etc.)
and snow fences to be installed on the west side of the new highway ROW (Appendix B, Landscape Plans). The
installation of these snow drift mitigation measures will improve as they become more established and will be
out of the way of future Highway 400 10-lane expansion. For additional details refer to Snow Drift Review, MTO
Hwy 400 Innisfil Beach Road, Barrie, Ontario, prepared by RWDI, dated September 23, 2019.
Cultural Environment
4.3.1 Archaeology
During the preliminary design study, a Stage 1 and 2 Archaeological Assessment Report was prepared to
document archaeological potential within the greater study area from Highway 89 to Highway 11 (AECOM,
2017a). Further, A Supplemental Documentation Report (AECOM, 2017b) was prepared to record the findings
and recommended Stage 3 Archaeological Investigation for a single site (H1, BbGW-78), located in the
northwest quadrant of the BCR bridge.
MP retained Past Recovery Archaeological Services to conduct further Stage 1, 2 & 3 Archaeological
Assessments in the project study area. The Stage 1 and 2 Assessments were conducted within the study area
not covered by the AECOM 2017a Report. The Stage 1 and 2 Assessments found no additional potential
archaeological resources within the study area, other than the H1 site noted above.
Design and Construction Report Highway 400 Structures, Town of Innisfil
G.W.P 2493-15-00 MTO Assignment No. 2017-E-003
31
A Stage 3 Archaeological Assessment was conducted on the H1 site located in the northwest quadrant of the
BCR bridge. While the site appears to have had a relatively short occupation span of 20 to 25 years, it seems to
date from the mid-1860s to the mid-1880s and is thus fairly late for settlement in Innisfil Township (surveyed
in 1820), with at least half of the occupation post-dating 1870. Further, it appears that the cellar pit (the main
farmhouse feature) lies on the edge of the new ROW with only the small portion encountered in our test units
lying within (and thus already documented); the remainder of this feature will be unaffected by the proposed
work. Thus, no Stage 4 work will be recommended for this site
Details of the Stages 1 and 2 Archaeological Assessments can be found in the Stage 1 & 2 Archaeological
Assessments Report, prepared by Past Recovery Archaeological Services Inc., dated March 14, 2020.
Details of the Stage 3 Archaeological Assessment can be found in the Stage 3 Archaeological Assessment
Report, prepared by Past Recovery Services Inc., dated August 29, 2020.
4.3.2 Built Heritage and Cultural Heritage Landscape
McIntosh Perry retained Unterman McPhail Associates Heritage Resource Management Consultants to
complete a Cultural Heritage Technical Memorandum for the study area.
No cultural heritage landscape or built heritage resources recognized at the municipal, federal or international
levels are identified as being located within or adjacent to the study area. Therefore, there are no anticipated
potential impacts, including the abandoned farm complex located adjacent to the study area on southeast
corner of the intersection of Innisfil Beach Road and Sideroad 5. The eastern boundary of the Innisfil Cemetery
and Crematorium, which was opened in 1984 at 7551 Sideroad 5, is adjacent to west side of Highway 400.
There are no anticipated impacts to this property as a result of the proposed MTO work in the study area.
Highway 400 is considered to be a cultural heritage landscape of historical/associative interest or value to the
provincial history; however, its original highway design has been significantly altered.
Details of Built Heritage and Cultural Heritage Landscape within the study area can be found in the Cultural
Heritage Technical Report, prepared by Unterman McPhail Associates Heritage Resource Management
Consultants, dated May 6, 2019 (revised January 14, 2020).
Summary of Environmental Concerns and Commitments
The environmental protection/mitigation measures identified in the DCR have been incorporated into the
contract package to address potential environmental effects resulting from this project. Areas of environmental
sensitivity or concern, the sources of those concerns, and the mitigation measures associated with the
undertaking are described in Table 4.
