Thought to post this interesting story of a former top secret plan by the the Govt of Canada,during the cold war era to intern Canadians citizens who involvement or sympathize with the Canadian communist party from 1950-1983 era. The RCMP along with the Canadian Penitentiary Services would have carried out this operation in the event of world war three during the cold war tensions from this period. During the October Crisis of 1970, Communist sympathizers were also arrested in mass by the Police("The Sureté du Québec provincial police")and Montreal Police Force.
