Loi sur les mesures de guerre
The Emergencies Act replaced the War Measures Act in 1988. The War Measures Act was invoked three times in Canadian history, most controversially during the 1970 October Crisis, and also during World War I (from 1914 to 1920, against threat of Communism) and World War II (from 1942 to 1945, against perceived threat from Japanese Canadians following Imperial Japan's attack on Pearl Harbor).
