Internment of Italian Canadians

The internment of Italian Canadians was the forced relocation and incarceration of Italian Canadians during World War II following Italy's declaration of war against the United Kingdom on June 10, 1940. Through the War Measures Act, the government of Canadian Prime Minister William Lyon Mackenzie King gave itself the power to suspend habeas corpus, revoke rights, seize property and arrest those who were deemed a threat to the safety of Canada—labelling 31,000 Italian Canadians as "enemy aliens".
