We had the same kind of "Indian" schools in the US. While ostensibly, it was to educate 'savages' to accent the greater white man's culture, the children were hostages to ensure complaint, passive, acceptance of US Army rule, back in the reservations. I think initially most of the school's staff thought they were doing good, and for the benefit of the children. I understand that in US schools, for the kids, it was culture shock. Most had never lived in square wooden buildings. For the boys, they had to have their long hair,. as a sign of their manhood, and honor cut short. The kids were forever coming down with one contagious thing, or another. Deaths were common back then, amongst all children. I don't know about the types of abuse that occurred in Canada. I believe they were religious schools, but here in the US, they were government run.
