As of November 6, 2026, amendments to Part 8 of the Occupational Health and Safety Regulation, relating to face seals, are in effect.

These amendments clarify existing requirements for respirators that depend on an effective face seal and introduce consistent terminology, including the term "tight-fitting respirator." They also clarify that nothing can interfere with the seal or proper functioning of a tight-fitting respirator. The changes do not introduce new regulatory requirements for employers or workers.
