In Ontario, species that may be at risk are reviewed by a team of experts known as the Committee on the Status of Species at Risk in Ontario (COSSARO).
COSSARO can be made up of people with expertise in certain scientific disciplines, or Aboriginal Traditional Knowledge.
COSSARO has been around since 1995, but under the new ESA it is now a legally recognized committee that meets twice annually to determine the status of Ontario’s species.
COSSARO is an independent body that can be made up of up to 11 members from both the public and private sectors. At least five members must be from outside of the Ontario Government. The Minister of Natural Resources may make recommendations on committee members, but the final decision on who can be a member is made by the Lieutenant Governor in Council.
