Wildlife species assessment

Assessment process, categories, and guidelinesFootnote 1

Approved by Committee on the Status of Endangered Wildlife in Canada (COSEWIC) in November 2015

Overview of the COSEWIC ProcessFootnote 1

COSEWIC exists to provide Canadians and their governments with advice regarding the status of wildlife species that are nationally at risk of extinction or extirpation.

The COSEWIC process is divided into three sequential steps, each of which has a tangible outcome. These are detailed below.

  • selection of wildlife species requiring assessment - the COSEWIC Candidate List;
  • compilation of available data, knowledge and information - the COSEWIC status report; and
  • assessment of a wildlife species' risk of extinction or extirpation and subsequent designation - the record of COSEWIC assessment results.
