I am not so much surprised with the atrocities against natives. Those are common. It is a bit surprising to learn it about Canada, because the country has a good reputation and its history is not that well known. But:

Overcrowding, poor sanitation, and a lack of medical care led to high rates of tuberculosis, and death rates of up to 69 percent.

Those were schools! Schools with a death rate is so much against anything that I consider a school to be about. Its just wrong. It just looks like a relabeled death camp, and that defeats the point of education. That amount of ignorance is just mindblowing.
