Of the 13 species, subspecies and isolated populations of freshwater fish that have vanished from Canada, all but two are extinct globally. Paddlefish and gravel chub can still be found in the United States.

The extinct fish from western Canada were each endemic to only one lake. Many of the extinct Ontario species once inhabited the Great Lakes, including the population of Atlantic salmon which spent its entire life cycle in Lake Ontario.
