The correct answer is Health Canada, which is the regulatory body responsible for the Workplace Hazardous Materials Information System (WHMIS) in Canada. WHMIS is a comprehensive communication system designed to provide information about hazardous materials used in workplaces. Health Canada oversees the development and implementation of the WHMIS framework to ensure safety in the handling and use of hazardous materials, facilitating effective hazard communication through labels, safety data sheets, and worker education and training programs.

This aligns with the role of Health Canada in protecting the health and safety of Canadians by ensuring that hazardous materials are clearly labeled and that the risks associated with these materials are communicated effectively to workers. By establishing regulations and guidelines regarding WHMIS, Health Canada helps create a safer work environment, ensuring that employees are well-informed about the hazards they may encounter on the job. This regulatory oversight is crucial for compliance and helps prevent workplace accidents and injuries related to hazardous materials.
