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.
