Polar bear


The world's largest land carnivore, a male polar bear can reach two to three metres in length and weigh between 300-800 kilograms. Adult females are smaller and can weigh between 150-400 kg.

Polar bears are found throughout the circumpolar North. The majority of bears live on sea ice around Canada’s Arctic Islands. The Northwest Territories (NWT) shares three sub-populations of polar bears, an estimate 3,000 bears, with neighbouring jurisdictions: Southern Beaufort Sea, Northern Beaufort Sea and Viscount Melville Sound. There is also a small number of bears in a fourth subpopulation, Arctic Basin.


Polar bears are as comfortable on land as they are in water and are quite agile in either environment. They follow the ice. In spring, polar bears can be found on the inhospitable land-fast ice and coastal pack ice where they prey primarily on ringed and bearded seals. They are carnivorous bears and meat makes up the majority of their diet. Polar bears are solitary hunters and feed primarily on seals, as well as walrus, whales, fish, and birds.

Once the ice melts in summer, polar bears spend several months on land. Reproductively active females spend the winter in dens they construct by digging into snowdrifts, usually on land but occasionally on the sea ice. Female polar bears may return to the same denning area every year. Males may also den but only during the harshest part of winter, usually in late January and February. Denning sites and spring feeding areas are important habitats for polar bears.


Polar bears are a species of Special Concern in Canada and the NWT. Management is guided by the Inuvialuit Settlement Region Polar Bear Joint Management Plan and the Framework for Action for Management of Polar Bears in the Inuvialuit Settlement Region.

Polar bears were internationally protected in 1976 under the International Agreement on the Conservation of Polar Bears. This agreement requires governments of all signing nations to manage the bears according to “sound conservation practices” and to conduct research related to the conservation and management of polar bears.

Under the Convention on International Trade in Endangered Species (CITES), any international shipment of polar bears or their parts requires a permit.

Polar Bears in Canada

Canada is home to about 16,000 polar bears, which is approximately two-thirds of the world’s total estimated population of  26,000 (95% Cl: 22,000-31,000) individuals. The global population is divided into 19 subpopulations, of which 13 are managed or co-managed by Canada. Over 90 percent of the polar bears in Canada occur in two of Canada’s northernmost territories: Nunavut and the Northwest Territories.
