Background Information Initiated by the Ontario Stone, Sand, and Gravel Association (OSSGA) in 2010◦ Not enough data available on the final land use condition of rehabilitated pits and quarries.

◦ MNRF is not required to track post surrender data◦ Establish and maintain a database

OSSGA Rehabilitation Database◦ Includes 1,457 records◦ Data from ALPS, MNR staff, MNR office visits◦ Limited site information available

Data collection by OSSGA Staff◦ Field visits during 2010‐2014◦ Data stored in a searchable and sortable database◦ Pictures taken for each site


Study Objective & Scope• Investigate, assess, and document the rehabilitation status and land use condition of surrendered pits and quarries across Ontario. Only surrendered licences (not active sites or progressive rehabilitation) Licences issued and managed by the MNR under the PCQA or the ARA (does not include unlicensed or revoked sites)


To date:• 701 sites surveyed• 19 complete Regional Rehabilitation profiles• Data for over 100 municipalities

Discussion of Results1. Pit and quarries are successfully

rehabilitated to a range of productive final land‐uses

2. Pit and quarry rehabilitation supports the provincial priority (PPS 2014) of restoring and improving natural heritage values.

3. Aggregate extraction does not result in the permanent conversion of agricultural land.

4. Rehabilitation is supportive of local land‐use planning objectives.


Conclusions1. The final rehabilitation of licensed pits and quarries is

occurring satisfactorily in Ontario.

2. Rehabilitated and surrendered aggregate licences do not leave “open‐scars” on the landscape.

3. Licenced pits and quarries are successfully rehabilitated and reintegrated into rural or urban landforms.

Future Work1. Continue research & data collection.

2. Assess site‐specific ecology and agricultural productivity.

3. Implement best management practices for rehabilitation.

4. Monitor the long‐term success of rehabilitation

5. Improve data management & retention practices.
