CSIS’s role is to investigate activities suspected of constituting threats to the security of Canada and to report on these to the Government of Canada. Key threats include:
- The proliferation of weapons of mass destruction
- Foreign interference

If you believe you have information related to national security that CSIS should know about, please report it.
CSIS is not a law enforcement agency. To report an immediate threat to national security, please call 911 or your local police department.
