The Defence of Canada Regulations were a set of emergency measures implemented under the War Measures Act a week before Canada's entry into World War II in the fall of 1939. The extreme security measures permitted by the regulations included the waiving of habeas corpus and the right to trial, internment, bans on political and religious groups, restrictions of free speech including the banning of certain publications, and the confiscation of property. Section 21 of the Defence of Canada Regulations allowed the Minister of Justice to detain without charge anyone who might act "in any manner prejudicial to the public safety or the safety of the state." The Regulations were used to intern opponents of World War II, particularly fascists and Communists, as well as opponents of conscription such as Quebec nationalist and Montreal mayor Camillien Houde. It was under the regulations that Japanese Canadians were interned and their property confiscated for the duration of the war. German Canadians were required to register with the state and some German and Italian Canadians were detained.
