Uranium is a naturally occurring radioactive element that is mined and processed in order to make fuel for nuclear research reactors or power reactors. Canada is one of the world's largest producers of uranium.

The Canadian Nuclear Safety Commission (CNSC) regulates and licenses all operating and future uranium mining and milling operations, as well as all uranium processing and fuel fabrication facilities in Canada.

CNSC oversight also covers decommissioned sites of these operations. The CNSC performs all of its activities in order to protect the health, safety and security of Canadians and the environment.
