List of Wildlife Species at Risk (Canada)

The List of Wildlife Species at Risk currently has more than 800 entries for Canadian wild life species considered vulnerable; including 363 classified as endangered species, —190 threatened species, —235 special concern, and 22 extirpated (no longer found in the wild). About 65 percent of Canada’s resident species are considered "Secure". More than 30 wildlife species have become extinct in the wild since the arrival of European settlers.

The Government of Canada maintains a list of all plant and animal species, or designatable units (DUs) thereof, federally recognized as special concern, threatened, endangered, extirpated, and extinct in Canada under Schedule I of the Species at Risk Act (SARA).

SARA Schedule
Species listed on SARA Schedule I receive federal legal protections under the Act, including the protection of individuals, populations, and their habitat from harm. Listing on Schedule I of the act also mandates the formation of a species recovery team and strategy. The addition of species or DUs to Schedule I is done annually by the Minister of the Environment, based on formal assessment recommendations by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC), an independent committee of wildlife experts and scientists. COSEWIC assessments and IUCN designations by themselves are not to be confused with actual Schedule I listings as both of the former have no formal legal status in Canada.
