The Pacific Loon nests along the edges of freshwater ponds in Canada's western boreal forest and tundra regions. During the rest of the year, it is strictly marine, occurring primarily along the Pacific Coast. There are approximately 610,000 individuals breeding in Canada, which represents 73% of the global population and a high degree of responsibility for Canada. Nearly 200,000 more breed in Alaska and many of those migrate to or through western Canada, boosting the total proportion to as much as 96% and very high responsibility. The Canadian population of Pacific Loon has shown little change relative to 1970, based on the Christmas Bird Count. Although reliability of this source is low because of relatively poor coverage, overall confidence in the status is elevated to medium because the British Columbia Coastal Waterbird Survey for the Salish Sea also indicates little change. The national population of Pacific Loon is within its goal range.
