Prohibition of Certain Toxic Substances Regulations, 2025 (SOR/2025-270)
About the regulations
The Prohibition of Certain Toxic Substances Regulations, 2012 (the 2012 Regulations) will be repealed and replaced by the Prohibition of Certain Toxic Substances Regulations, 2025 (the 2025 Regulations) when the 2025 Regulations comes into force on June 30, 2026. Both these Regulations are made under the authority of the Canadian Environmental Protection Act, 1999.
The Regulations prohibit the manufacture, use, sale, and import of certain toxic substances, as well as products containing them, with a limited number of exemptions.
The 2025 Regulations further restrict the manufacture, use, sale and import of perfluorooctane sulfonate, its salts and its precursors (PFOS), perfluorooctanoic acid, its salts and its precursors (PFOA), long-chain perfluorocarboxylic acids, their salts and their precursors (LC-PFCAs), hexabromocyclododecane (HBCD), and polybrominated diphenyl ethers (PBDEs), and products containing them, by removing certain exemptions or limiting specific activities which were allowed under the 2012 Regulations.
The 2025 Regulations also prohibit two additional flame retardants, Dechlorane Plus (DP) and decabromodiphenyl ethane (DBDPE), and products containing them, with a limited number of exemptions.
In addition, the 2025 Regulations simplify the current Regulations by consolidating substance-specific requirements.
