The horrors of the Holocaust prompted many Allied countries to assess their own institutionalized prejudices. Prior to the Second World War, Adolf Hitler cited Canadian and American anti–Chinese immigration laws as precedents for discriminatory measures in Germany. During the war, Allied countries came to associate this overt racism with their enemies. Policies that targeted the Chinese were seen as particularly shameful because China was a wartime ally. The American government repealed its anti–Chinese immigration law during the war. The Canadian government did not, despite pressure that continued into peacetime.
