Commission members

We are pleased to announce that Pierre Tremblay has been appointed as CNSC President for a 5-year term effective August 12, 2024. Please read our news release to learn more.


The Nuclear Safety and Control Act provides for the appointment of up to 7 permanent members, appointed by the Governor in Council based on their qualifications and expertise. Commission members may be removed only for cause. Most members are appointed on a permanent, part-time basis, meaning they also have individual jobs. Temporary members can also be appointed to the Commission. Commission members commit to the highest standards of ethics and conflict-of-interest guidelines, and carry out their duties impartially.

The President of the Commission is appointed to hold office as a Commission member during good behaviour, and is also designated by the Governor in Council to hold office as President – a full-time rather than part-time position.
