Which regulatory body enforces legal requirements for laboratory decommissioning if radioactive materials are used?

The Canadian Nuclear Safety Commission (CNSC) is the regulatory body responsible for enforcing legal requirements for the handling, use, and decommissioning of facilities that use radioactive materials in Canada. This includes setting safety standards for nuclear facilities and ensuring compliance with laws designed to protect public health, safety, and the environment.

The CNSC's authority stems from the Nuclear Safety and Control Act, which mandates that any organization dealing with nuclear substances must adhere to stringent safety guidelines and decommissioning procedures. This ensures that when laboratories that utilize radioactive materials are shut down, they comply with specific safety protocols to minimize risk of radiation exposure and contamination, contributing to the overall safety of the community and the environment.

The other options listed are involved with various aspects of health and safety but do not specifically oversee radioactive materials or decommissioning processes related to them. For instance, the Health and Safety Commission focuses on occupational health and safety regulations in general, while the Canadian Centre for Occupational Health and Safety promotes health and safety practices across all workplaces but does not specifically handle nuclear materials. The Canadian Commission involves different regulatory oversight unrelated to nuclear safety and is not a recognized body in this context. Thus, the Canadian Nuclear Safety Commission is the correct regulatory authority for laboratory decommissioning involving radioactive
