For the record — "This is not an aboriginal story. This is not only about the experience of those who were students in the school. This is also the story about Canada's experience. While they were indoctrinating aboriginal people into believing that their people were inferior, their languages were irrelevant, their cultures were not worth protecting, the very same message was being given to students in public schools in this country." — Sinclair on Canada's residential school policy.
