and what of the other crimes I listed that the Canadian government took a direct hand in perpetrating?

It is not one or the other. It was both. Both the church staff who perpetrated beatings, sexual abuses and rapes but it was the Canadian government who purposefully starved children, sometimes to death at the schools.

From my link about the horrible experiments conducted on children at residential schools by the Canadian government.

>The First Nations nutrition experiments were a series of experiments run in Canada by Department of Pensions and National Health (now Health Canada) in the 1940s and 1950s. The experiments were conducted on at least 1,300 Indigenous people across Canada, approximately 1,000 of whom were children. The deaths connected with the experiments have been described as part of Canada's genocide of Indigenous peoples.

Done under the watchful supervision of the Canadian Government.
