The RCMP Security Service was a specialized political intelligence and counterintelligence branch with national security responsibilities, replaced by the Canadian Security Intelligence Service (CSIS) in 1984, following revelations of illegal covert operations relating to the Quebec separatist movement. CSIS is not part of the RCMP, but is its own entity. In the late 1970s, revelations surfaced that the RCMP Security Service force had in the course of their intelligence duties engaged in crimes such as burning a barn and stealing documents from the separatist Parti Québécois, and other abuses. This led to the Royal Commission of Inquiry into Certain Activities of the RCMP, better known as the "McDonald Commission", named for the presiding judge, Justice David Cargill McDonald. The commission recommended that the force's intelligence duties be removed in favour of the creation of a separate intelligence agency, the Canadian Security Intelligence Service. The RCMP and CSIS nonetheless continue to share responsibility for some law enforcement activities in the contemporary era, particularly in the anti-terrorism context.
