History of the Canadian Nuclear Safety Commission

On October 12, 1946, the Government of Canada proclaimed the Atomic Energy Control Act. Under the Act, the Atomic Energy Control Board was formed as a regulatory agency to provide for “control and supervision of the development, application and use of atomic energy and to enable Canada to participate effectively in measures of international control of atomic energy.”

On May 31, 2000, the Nuclear Safety and Control Act replaced the Atomic Energy and Control Act and the Canadian Nuclear Safety Commission (CNSC) was established. The new act provided the CNSC with the authority 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 Canada.
