Which entity regulates occupational health and safety in the workplace?

The regulation of occupational health and safety in the workplace primarily falls under the jurisdiction of provincial or territorial occupational health and safety authorities. Each province and territory in Canada has its own set of laws and regulations that govern workplace safety standards and practices. These authorities are responsible for enforcing compliance, providing guidelines, and conducting inspections to ensure that workplaces adhere to health and safety standards designed to protect workers.

While Health Canada has a role in broader health initiatives and can influence policies around health and safety, it does not specifically regulate workplace safety across all sectors. The Canadian Centre for Occupational Health and Safety provides information and resources on occupational health and safety, but it does not serve as a regulatory body. The Department of Labour also plays a role in workplace matters but is more focused on labor relations and labor standards rather than direct regulation of occupational health and safety in individual workplaces.

Thus, the correct answer reflects the primary regulatory bodies that are specifically dedicated to overseeing and enforcing occupational health and safety laws at the provincial and territorial levels.
