The Canadian Arctic tundra is a biogeographic designation for Northern Canada's terrain generally lying north of the tree line or boreal forest, [2] [3] [4] that corresponds with the Scandinavian Alpine tundra to the east and the Siberian Arctic tundra to the west inside the circumpolar tundra belt of the Northern Hemisphere.

The Canadian High Arctic Tundra ecoregion encompasses most of the northern Arctic archipelago, from much of Baffin Island, Somerset Island, and Prince of Wales Island in the south, through all islands northward to the most northern island in Canada, Ellesmere Island. [3]

[2] Due to its vast geographical expanse and to history of research, the Pre-Dorset is difficult to define.
The Dorset was a Paleo-Eskimo culture, lasting from 500 BCE to between 1000 CE and 1500 CE, that followed the Pre-Dorset and preceded the Thule people (proto-Inuit) in the North American Arctic. The culture and people are named after Cape Dorset (now Kinngait) in Nunavut, Canada, where the first evidence of its existence was found. The culture ...
