An endangered species is any native species that "is at risk of extinction or extirpation throughout all or a significant portion of its Ontario range". For purposes of the Conservation Land Tax Incentive Program, endangered species are those listed in regulation under Ontario's Endangered Species Act. At present, 42 species are listed in regulation under the Act.
Endangered species habitat is the habitat which is necessary for the survival of populations of endangered species. The specific requirements of the various endangered species are set out in MNR guidelines for mapping this habitat. These guidelines are used to delineate endangered species habitat on a species-by-species and site-by-site basis.
For a list of regulated Endangered Species in Ontario, view MNR Rankings by visiting the Species at Risk in Ontario (SARO) website.
More information on these and other Species at Risk is available on the Royal Ontario Museum website.
