CSIS is Canada’s security and intelligence service. Its role is to investigate activities suspected of constituting threats to the security of Canada and to report 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.
CSIS collects and analyzes threat-related information, which is typically disseminated to government partners through intelligence reports and other intelligence products. Key threats include terrorism, the proliferation of weapons of mass destruction, espionage, foreign interference and cyber-tampering affecting critical infrastructure.
Through its Security Screening Program, CSIS prevents non-Canadians who pose security concerns from entering Canada or receiving permanent resident status or citizenship. CSIS also safeguards the confidential information of the Government of Canada from foreign governments and other entities that may present a risk.
