Species at risk guides and resources
Standards, guidelines, reference materials and technical resources related to the Endangered Species Act and its regulations.
Species Conservation Act now in force
The Endangered Species Act, 2007 (ESA) and its regulations have been repealed. The Species Conservation Act, 2025 (SCA) and its regulations are now in force. Find more information on the Environmental Registry of Ontario (notice 025-0380 , notice 025-0909) and e‑Laws.
This information provides general guidance only. If you are planning an activity that may affect a species on the Protected Species in Ontario List, review the SCA and its regulations. You should also seek appropriate advice, such as legal or scientific advice, or contact SAROntario@ontario.ca.
If there is any inconsistency between this webpage and the SCA or its regulations, the legislation prevails.
