SG 012/26
The Prohibition of Certain Toxic Substances Regulations, 2025, marks a significant expansion of Canada’s environmental policy, officially replacing the 2012 framework on June 30, 2026.
On December 31, 2025, Canada published the Prohibition of Certain Toxic Substances Regulations, 2025 (SOR/2025-270), in the Canada Gazette, Part II. These regulations repeal and replace the 2012 version, introducing stronger controls on persistent and bioaccumulative toxic substances to better protect human health and the environment. The regulations are officially set to come into force on June 30, 2026.
The 2025 Regulations significantly tighten restrictions on the manufacture, sale and import of high‑risk chemicals, including several PFAS and other high-concern substances. They also introduce new bans on the following flame retardants Dechlorane Plus (DP) and decabromodiphenyl ethane (DBDPE). To assist with the transition, the government has established time-limited, sector-specific exemptions for essential industries such as aerospace, automotive and electronic manufacturing. Businesses may apply for temporary permits to import certain products containing prohibited substances, provided they adhere to strict reporting and record-keeping requirements. Ultimately, the regulatory update aligns Canada with international chemical safety standards and encourages the shift toward safer alternatives.
The regulations cover the toxic substances listed in Schedule 1 of the Canadian Environmental Protection Act (CEPA), as well as products containing these substances. Key updates include:
The 2025 Regulations also introduce a permit system for short-term use of restricted substances. Permits are valid for one year and may be renewed up to two times, allowing a maximum of three years of use. To obtain a permit, applicants must show that no technically or economically feasible alternatives are available, take steps to minimize environmental and health impacts, and provide a compliance plan to fully meet the regulations within the maximum three-year period. This system supports the transition to safer alternatives and more sustainable practices.
To comply with the 2025 Regulations, companies should act promptly by screening their supply chains for newly regulated substances, checking the revised exemption criteria for restricted substances and preparing permit applications for any allowed exempted uses. It is also advisable to begin planning for substitution by identifying and evaluating safer alternatives, ensuring a smooth transition and achieving full compliance before the regulations take effect.
