It had a dreadful history that spanned several decades. It's a history that today's Canadians are ashamed of, and the scars have lingered for generations. Indigenous peoples in the country, many of whom were of Indian ancestry, were forcibly removed from their homes as children, transferred to a network of residential schools, and forced to adapt to "civilized" culture by harsh discipline and frequently brutal processes. The documentary Canada's Dark Secret reveals this horrible method of brainwashing and tells the lives of several survivors.
