The Lowland Regions
The Lowland Regions
• There are three lowland areas in Canada.
• The Great Lakes-St. Lawrence Lowlands,
• The Hudson Bay Lowlands, and
• The Arctic Lowlands.
The Lowland Regions
The Great Lakes-St. Lawrence Lowlands
• The smallest of the regions in terms of physical size.
• It is the largest though, in terms of population (About 60% of Canada’s population).
• This region also contains about 65% of Canada’s manufacturing industries.
The Great Lakes-St. Lawrence Lowlands
• As the name implies, this region is divided into two parts.
• The Great Lakes Lowlands stretches from Southwestern Ontario along the shores of Lakes Erie and Ontario to the St. Lawrence River northeast of Kingston.
• The St. Lawrence Lowlands follows the river towards Quebec City and the Gulf of St. Lawrence.
The Great Lakes-St. Lawrence Lowlands
• Similar to the Interior Plains, sediments were deposited in this region from the Canadian Shield, as well as from the Appalachians.
• Layers of limestone, sandstone, and shale lie beneath the surface.

Hudson Bay Lowlands
• This area is found to the South of Hudson Bay.
• It is composed of flat layers of sedimentary rock that rests atop the Canadian Shield.
• At one time, most of the area would have been covered by Hudson Bay.
• This region is also the 3rd largest wetland in The World.
The Lowland Regions
The Arctic Lowlands
• These lowlands are scattered among islands of the far north.
• Like The Hudson Bay Lowlands, this region consists of sedimentary rock resting on older rock of the Canadian Shield.
Arctic Lowlands
• Like The Interior Plains, this region contains many valuable mineral resources.
• As well, the ground remains frozen for most of the year.
