CNSC’s Role

The mandate of the Canadian Nuclear Safety Commission (CNSC) is to protect the health and safety of Canadians, as well as our environment. Government of Canada departments and agencies also help CNSC fulfill its mandate. This is true especially for people who live or work in communities where licensed operators of nuclear substances are located.

The CNSC regulates the use, possession and storage of all nuclear substances in Canada. These regulatory requirements for safety and security controls of radioactive sources have been strengthened over the years as a result of increased knowledge on the effects of radiation.

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.

Part of the CNSC's mandate is to disseminate objective scientific, technical and regulatory information to the public. The purpose of this site is to provide clear and simple information about radiation - the types of radiation that exist, its sources, uses, and the rules in place to protect Canadians, and people who work in or live near nuclear facilities.
