Can CSIS investigative techniques be arbitrarily deployed?
No. All intrusive methods of investigation used by CSIS are subject to several levels of approval before they are deployed. The most intrusive methods, such as electronic surveillance, mail opening, and covert searches, require a warrant issued by a judge of the Federal Court of Canada. SIRC and the IG closely review CSIS operations to ensure they are lawful and comply with the Service’s policies and procedures.
