Canadian Nuclear Safety Commission regulations under the Single Window Initiative

The Canadian Nuclear Safety Commission (CNSC) regulates the use, possession and storage of all nuclear substances in Canada to protect the health and safety of Canadians, as well as the environment.

The objects of the Commission are to:

  • Regulate the development, production and use of nuclear energy and the production, possession and use of nuclear substances, prescribed equipment and prescribed information in order to prevent unreasonable risk to the:
      • environment and to the health and safety of persons, associated with that development, production, possession or use,
      • national security associated with that development, production, possession or use, and
      • achieve conformity with measures of control and international obligations to which Canada has agreed; and
  • Disseminate objective scientific, technical and regulatory information to the public concerning the activities of the Commission and the effects, on the environment and on the health and safety of persons, of the development, production, possession and use referred to in paragraph (a).

The CNSC has a strong licensing and compliance system to ensure that all persons who use, possess and store nuclear substances and radiation devices do so in accordance with a licence and have in place safety and security provisions that are balanced with the risks associated with the substance or device.
