Canada Publishes 2025 PFAS Report, Signalling Stricter Regulations
Canada’s 2025 PFAS report signals stricter regulations on manufacturers and supply chains. Find out how these changes impact your industry and compliance strategy.
The Canadian government has introduced new regulations prohibiting the manufacture, import, and sale of sealant products containing coal tars, polycyclic aromatic hydrocarbons (PAHs), and 2-butoxyethanol. Published under the Canadian Environmental Protection Act, 1999 (CEPA), these rules will take effect between October 2025 and July 2028. The ban aims to reduce environmental contamination and protect public health.

New Regulatory Requirements
Coal Tar and PAH-Based Sealants Face Restrictions
From 1 October 2025, it will be illegal to manufacture or import sealant products containing coal tars or PAHs exceeding 1,000 ppm in Canada. Sales of these products will be prohibited from 31 December 2025, with a temporary exemption until 1 July 2028 for industrial uses such as metal, structural steel, and pipeline applications.
Limits on 2-Butoxyethanol in Cleaning Products
The regulations also impose concentration limits on 2-butoxyethanol, a solvent used in cleaning and paint products. Different product categories, including floor strippers, rug cleaners, and aerosol paints, must comply with specified concentration limits to minimise human exposure risks.
Impact on Manufacturers and the Supply Chain
Compliance Deadlines and Permit System
Manufacturers and importers must cease production and sales of affected products by the given deadlines unless they obtain a government permit. Permits will be granted only if no safer alternatives are technically or economically feasible.
Environmental and Health Implications
Coal tar-based sealants contain high levels of PAHs, known to cause cancer and environmental contamination. The move aligns with global trends, including EU REACH regulations and state-level bans in the U.S.. Businesses should identify substitute materials and prepare for market shifts.
What Should Industry Stakeholders Do Next?
- Review product formulations and assess if current offerings comply with new limits.
- Seek alternative materials such as asphalt-based sealants or lower-toxicity chemicals.
- Apply for permits if no feasible substitutes exist, ensuring compliance by 2025.
