On December 31, 2025, the Federal Government published the Prohibition of Certain Toxic Substances Regulations, 2025 (2025 Regulations) under the Canadian Environmental Protection Act, 1999 (CEPA). When they come into effect on June 30, 2026, the 2025 Regulations will repeal and replace the Prohibition of Certain Toxic Substances Regulations, 2012 (2012 Regulations). The Federal Government published a proposed version of the 2025 Regulations in 2022 for public consultation.

Like the 2012 Regulations, the 2025 Regulations will prohibit the manufacture, use, sale and import of certain toxic substances, and products containing them (excluding incidental presence), with limited exemptions. The 2025 Regulations will remove certain exemptions that are available under the 2012 Regulations and will impose new restrictions in an effort to further reduce concentrations of specific toxic substances in the environment.
