The extreme security measures permitted by the Defence of Canada 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. S. 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 government soon interned fascists and Communists as well as opponents of conscription. The regulations were later used to intern Japanese Canadians on a large scale as well as some German and Italian Canadians who were viewed as enemy aliens.
