Canada Releases Multi-Year Chemical Assessment Priorities Under CEPA

On July 23, 2025, Environment and Climate Change Canada published its Plan of Priorities, a multi-year roadmap identifying 30 chemicals—including nanoscale silver, zinc oxide, and titanium dioxide - targeted for assessment under the Canadian Environmental Protection Act (CEPA). The list may be updated over time and will undergo a formal review in eight years.

What this means for business

Companies manufacturing, importing, or using priority chemicals should monitor upcoming assessment timelines and gather safety data proactively.

Manufacturers of nanomaterials must ensure compliance with both CEPA requirements and sector-specific rules (e.g., UV filter approvals for nanoscale zinc oxide in cosmetics).
