,On December 31, 2025, the Government of Canada published the Prohibition of Certain Toxic Substances Regulations, 2025 (SOR/2025-270) in the Canada Gazette, Part II, under the Canadian Environmental Protection Act, 1999 (CEPA). The regulations repeal and replace the 2012 framework and prohibit the manufacture, use, sale, offer for sale, and import of specified toxic substances and products containing them, subject to limited and time-bound exemptions. The updated rules strengthen controls on several persistent, bioaccumulative, and toxic substances, including perfluoroalkyl and polyfluoroalkyl substances (PFOS, PFOA, and long-chain PFCAs), polybrominated diphenyl ethers (PBDEs), hexabromocyclododecane (HBCD), Dechlorane Plus, and decabromodiphenyl ethane (DBDPE). Compared to the previous regulations, the 2025 amendments remove or narrow existing exemptions, expand prohibitions to additional substances, and consolidate requirements into a single regulatory instrument to improve clarity and enforcement. The regulations aim to reduce risks to human health and the environment from long-term exposure to these substances and are scheduled to enter into force on June 30, 2026.
