The 
Canadian Arctic is a vast region of northern 
Canada. Technically the term covers that portion of Canada north of the 
Arctic Circle; a more practical definition is that portion north of the 
tree line[?], a definition that includes the country's geographical centre. Canada claims that its territory extends all the way north to the 
North Pole, although this claim is not recognized by other countries, particularly the United States.
A political definition consists in Canada's three territories: Yukon, the Northwest Territories, and Nunavut.
