 With the 1945 Gouzenko Affair occurring in Canada, which was a main contributor to the start of the Cold War and the threat of the Korean War becoming the precursor for a Third World War, the Government of Canada in 1950 determined a need to create a blacklist of potential subversives.This was made the responsibility of the Royal Canadian Mounted Police's (RCMP) Special Branch, later the name was changed to the RCMP Security Service.In the 1950s, RCMP Commissioner Stuart Wood had a "PROFUNC list" of approximately 16,000 suspected communists and 50,000 suspected communist sympathizers.
