• Nunavut is the newest territory Created in 1999

Glaciers

• Glaciers are giant ice sheets that are slowly moving

• Glaciers moved across Canada thousands of years ago, and made the landforms that are present today, like mountains and lakes

Shield and Tundra• The Canadian Shield

is formed from ice sheets that depressed the land surface and scooped out thousands of lake basins. It carried away much of the region's soil. Drainage is generally very poor on the shield. The southern part of the shield has thick forests while the north is covered with tundra.

• Tundra is a treeless plain where the soil beneath a few inches is permanently frozen. Located in Canada’s far north.
