Oversight and review


CSE operates under a robust system of independent oversight.

  • Intelligence Commissioner 
  • National Security and Intelligence Review Agency (NSIRA)
  • National Security and Intelligence Committee of Parliamentarians (NSICOP)

Several external oversight and review bodies make sure CSE’s activities comply with our mandate and legal responsibilities. They also make recommendations for improvement. Once completed, they publish unclassified summaries of their reports.

Intelligence Commissioner

The Intelligence Commissioner is a retired superior court judge. They are independent of CSE. The Intelligence Commissioner is responsible for reviewing and approving Ministerial Authorizations before they take effect, making sure they are reasonable and that they comply with the CSE Act.

This work is important because CSE seeks Ministerial Authorizations when our activities may contravene an Act of Parliament or infringe on a Canadian’s reasonable expectation of privacy. For instance, when a foreign intelligence activity might result in the incidental gathering of a Canadian’s private communication, a Ministerial Authorization would be required.

The Intelligence Commissioner decides whether or not the action is reasonable and if the Authorization can take effect.

The Intelligence Commissioner submits an annual report to the Prime Minister who, in turn, tables it in Parliament.

National Security and Intelligence Review Agency (NSIRA)

The National Security and Intelligence Review Agency (NSIRA) is responsible for reviewing national security and intelligence activities across the Government of Canada, including CSE’s.

It is fully independent of government and of CSE.

NSIRA reviews our activities to ensure they are lawful, reasonable and necessary.

In addition, it reviews any complaints submitted against CSE actvities.

NSIRA has the right to access any information it needs to complete its reviews. The only exception is information covered by Cabinet confidentiality.

NSIRA is led by a committee of up to seven members, appointed on the advice of the Prime Minister, in consultation with the leaders in the House of Commons and Senate.

NSIRA provides classified reports of its findings and recommendations to relevant ministers. It also produces an annual unclassified public report to Parliament summarizing these findings and recommendations.

Before the creation of NSIRA in 2019, CSE’s activities were reviewed by the Office of the CSE Commissioner.

National Security and Intelligence Committee of Parliamentarians (NSICOP)

The National Security and Intelligence Committee of Parliamentarians (NSICOP) is a committee of Parliamentarians that have the security clearances to review and report on any aspect of CSE’s activities. The committee is mandated to review:

  • the legislative, regulatory, policy, administrative and financial framework for national security and intelligence
  • any activity carried out by a department that relates to national security or intelligence, unless the activity is an ongoing operation and the appropriate Minister determines that the review would be injurious to national security
  • any matter relating to national security or intelligence that a Minister of the Crown refers to the Committee
