The CSE Commissioner’s mandate under section 273.63 of the National Defence Act consists of three important functions:
The National Defence Act (subsection 273.65(8)) also requires that the Commissioner review CSE activities under a ministerial authorization and private communications to ensure they are authorized.
Under the National Defence Act, the CSE Commissioner must be a supernumerary or retired judge of a superior court. His main responsibilities are to review the lawfulness of CSE activities and to verify that CSE takes sufficient measures to protect the privacy of Canadians.
The Commissioner’s legislative mandate includes:
The Commissioner sends classified reports on his reviews to the Minister of National Defence. As the minister responsible for CSE, the Minister of National Defence can — and does — direct CSE to implement the Commissioner’s recommendations.
The Commissioner determines the contents of his reports, which are based on facts and conclusions drawn from those facts. The reports are free from any interference by CSE or any minister.
By law, the Minister of National Defence must table the Commissioner’s public annual report in Parliament.
Under section 15 of the Security of Information Act, the Commissioner also has a mandate to receive information from persons who are permanently bound to secrecy if they believe it is in the public interest to release special operational information of CSE.
