Critical Habitat for Aquatic Species at Risk - Canada

The Species at Risk (SAR) Program is responsible for carrying out DFO’s mandate under the Species at Risk Act (SARA) to protect, recover and conserve all listed aquatic SAR in Canada.

Critical habitat is identified for species listed as Endangered or Threatened under the Species at Risk Act (SARA).

This mapping tool is for general guidance only. “Mapped” representations of waterbodies and watercourses are based on authoritative provincial geospatial products, guidance and standards. Due to the nature of dynamic systems and the resolution/accuracy of these data sets, areas within which critical habitat is found as displayed on the mapping tool may not align exactly with natural watercourses. If discrepancies occur, refer to the relevant species recovery strategy and/or action plan for additional information on critical habitat. If additional guidance is required, please contact the Fish and Fish Habitat Protection Program: https://www.dfo-mpo.gc.ca/pnw-ppe/contact-eng.html

Critical habitat is defined under section 2 of SARA as: "the habitat that is necessary for the survival or recovery of a listed wildlife species and that is identified as the species' critical habitat in the recovery strategy or in an action plan for the species". Section 49(1)(a) of SARA requires that a species' Recovery Strategy/Action Plan include an identification of the species' critical habitat to the extent possible, based on the best available information, including information provided by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). SARA makes it illegal to destroy any part of the critical habitat of SAR and may impose restrictions on development and construction.

Critical habitats were assembled by SARA regional biologists and recovery teams. They are designed to support the protection and recovery of species listed as Endangered or Threatened under the Species at Risk Act. They are also described and displayed in species' Recovery Documents and Action Plans.
