Regulatory actions

Under the Nuclear Safety and Control Act and associated regulations, the CNSC can take various levels of regulatory action to protect the health, safety and security of Canadians, and the environment.

Please note: Once licensees have completed all corrective measures related to a regulatory action, the CNSC considers the action closed. At present, taking into account the special circumstances of the COVID-19 pandemic, all orders will be removed from this web page upon closure. All closed orders remain available in our annual Regulatory Oversight Reports.
