Canadian Security Intelligence Service
We are a federal institution that is part of the Public Safety Canada portfolio.
The Canadian Security Intelligence Service (CSIS) is at the forefront of Canada's national security system. CSIS’ role is to investigate activities suspected of constituting threats to the security of Canada and to report on these to the Government of Canada. CSIS may also take measures to reduce threats to the security of Canada in accordance with well-defined legal requirements and Ministerial Direction.
We are in the process of moving our services and information to Canada.ca.
Our current Canadian Security Intelligence Service website will remain available until the move to Canada.ca is complete.
