On April 1, 2024, significant amendments to the Conservation Authorities Act (the “CA Act”) and a new regulation under the Act, came into effect. This new regulation, Ontario Regulation 41/24: Prohibited Activities, Exemptions and Permits, ( “O. Reg. 41/24”), revoked and replaced the 36 individual regulations that governed Conservation Authorities. The new regulation governs prohibited activities, exemptions and permits under the CA Act.
