Canada’s Security Intelligence Service (CSIS) operates on a very different model from the American CIA, being neither strictly a foreign intelligence agency nor a domestic intelligence agency. Today SPY Historian Mark Stout discusses CSIS with Ray Boisvert, who was one of the founding members of the Service in 1984 and rose to become its Assistant Director, Intelligence, a position from which he retired in 2012. Hear them talk about the concept of “security intelligence” in a democratic society and explore the dilemmas which the Service faces in an era of terrorism emanating from groups such as al Qaeda and foreign covert influence from nation states.
