In 1942, internment of Japanese Canadians occurred when over 22,000 Japanese Canadians, comprising over 90 percent of the total Japanese Canadian population, from British Columbia were forcibly relocated and interned in the name of national security. The majority were Canadian citizens by birth. This decision followed the events of the Japanese invasions of British Hong Kong and Malaya, the attack on Pearl Harbor in Hawaii, and the subsequent Canadian declaration of war on Japan during World War II. This forced relocation subjected many Japanese Canadians to government-enforced curfews and interrogations, job and property losses, and forced repatriation to Japan.
