If you’re curious about where most polar bears spend their lives, Canada is the place to look first. Roughly two-thirds of the world’s polar bears live in Canada, which makes it the country with the biggest polar bear population. That’s a big deal, honestly—where these bears live really shapes the risks they face and what people can actually do to help.
Let’s talk about how ice, seals, and the shifting Arctic seasons affect polar bears. Conservation efforts vary from country to country, and all these pieces connect—habitat, population, and the choices people make—so it’s worth seeing how it all fits together.
Which Country Has the Most Polar Bears?
Canada has the biggest share of the world’s polar bears. It covers many of the main regions where these bears hang out.
Let’s look at which parts of Canada matter most, why Churchill, Manitoba gets so much attention, and how other countries’ populations stack up.
Canada’s Dominance and Regions
About two-thirds of all polar bears live in Canada. You’ll find most of them along the Arctic coasts and on islands in Nunavut, the Northwest Territories, and parts of northern Quebec and Labrador.
Major populations stick close to sea ice because that’s where they hunt seals. For example, Southern Hudson Bay has a group you can spot from shore during fall when the ice starts to form. The Western Hudson Bay group deals with earlier ice melt and longer stretches on land without food.
Nunavut has several coastal groups that follow the sea ice as it moves. Provinces and territories manage and monitor these bears, and indigenous communities play a big role in counting bears and helping with conservation.
Polar Bear Capital: Churchill, Manitoba
Churchill, Manitoba, proudly calls itself the “Polar Bear Capital of the World.” Every October and November, you can see lots of bears there waiting for Hudson Bay to freeze.
Tour operators offer guided trips on the tundra so you can watch the bears safely and support local conservation at the same time. Churchill’s spot on the Hudson Bay coastline means tourists get reliable bear sightings without trekking deep into the Arctic.
Researchers also come to Churchill to study how the bears live, move, and interact with people. Local rules keep close encounters in check and encourage guided tours, so both visitors and bears stay out of trouble.
Population Estimates by Country
Scientists estimate there are about 20,000 to 31,000 polar bears worldwide. Canada has around 13 of the 19 recognized Arctic subpopulations, which works out to about two-thirds of all polar bears.
The United States (mainly Alaska) has anywhere from a few hundred to a few thousand bears, mostly in the Chukchi Sea and Southern Beaufort Sea regions. Russia and Greenland have thousands too, but not as many as Canada.
Svalbard (Norway) has a smaller population. Numbers change as survey methods improve and ice conditions shift, so researchers update the estimates often.

Polar Bear Habitat and Conservation Challenges
Polar bears live in and around Arctic sea ice. They hunt seals, breed, and raise cubs out there.
Let’s dig into how their Arctic range splits into subpopulations, why shrinking sea ice is such a problem, and who’s actually working to protect them.
Arctic Range and Subpopulations
You’ll find polar bears all along the Arctic coasts of Canada, Alaska (USA), Greenland, Russia, and Norway. Scientists split them into 19 or 20 subpopulations, depending on geography and sea ice patterns.
Some of the better-known groups live in Hudson Bay and the Southern Beaufort Sea. Subpopulations really matter because sea ice and prey availability can be so different from one area to the next.
For instance, in Hudson Bay, bears have to deal with long summers without ice, while some Russian bears still use multi-year ice. Researchers, like those from the IUCN Polar Bear Specialist Group, track these groups to see which ones are stable, declining, or just lacking data.
These subpopulation assessments guide management decisions such as hunting limits and travel guidelines.
Climate Change and Sea Ice Habitat
Arctic temperatures keep rising, and that’s thinning out sea ice and making it melt earlier. When sea ice disappears sooner in spring and comes back later in fall, polar bears lose hunting time.
They end up fasting longer on shore, which isn’t great for their health. As sea ice shrinks, seals—the main food for polar bears—move around or become less common, so bears sometimes wander farther or show up near coastal towns looking for food.
Losing multi-year ice means some populations lose stable hunting and denning spots. These changes lead to local weight loss, fewer cubs surviving, and even push some groups farther north. It’s a tough situation, honestly.
Conservation Efforts and Organizations
A bunch of national agencies and NGOs actively work to protect polar bears and their sea ice habitat. The 1973 Agreement on the Conservation of Polar Bears, along with the IUCN Polar Bear Specialist Group, helps coordinate international efforts. These groups pick research priorities and organize population surveys.
You’ll spot conservation actions at all sorts of levels. Local communities come up with conflict-reduction plans to keep both bears and people out of trouble.
Governments step in and limit industrial activity in important habitats. Meanwhile, NGOs put money into research and public education.
Organizations like Polar Bears International actually support respectful tourism, letting people learn about bear ecology without causing much disturbance. All these efforts try to keep sea ice habitats safe and manage bear subpopulations using the best data they can get.
