British Columbia retains existing limits during 2026 review

WorkSafeBC placed the June 2026 exposure-limit recommendations on British Columbia's excluded-substances table pending review. Existing limits continue; those recommendations do not automatically replace them, and the exact notice date was not verified.

Scope to keep in mind

A new recommendation does not establish a revised legal limit while the substance remains excluded pending review.
