Chinese Immigration Act, 1923

The Chinese Immigration Act, 1923 (French: Loi de l'Immigration Chinoise, 1923), also known as the "Chinese Exclusion Act" (the duration of which has been dubbed the Exclusion Era), was a Canadian Act of Parliament passed by the government of Liberal Prime Minister William Lyon Mackenzie King, banning most forms of Chinese immigration to Canada. Immigration from most countries was controlled or restricted in some way, but only the Chinese were completely prohibited from immigrating to Canada.
