As a Canadian who had nothing to do with tearing down statues, I think it is fair to say that Canada's history is far more complex than all of this makes it sound.
As an example, our first Prime Minister, John A. McDonald was born in Glasgow, Scotland. Canada was not a confederation until 1867. Many of the men involved in confederation were UK born.
A good number of my ancestors were United Empire Loyalists, who left the US during the War of Independence because they were loyal to the Crown. Another good number came from Scotland.
Canada was not created out of thin air and populated by white anglophones. We have three founding groups. French, English, and aboriginal. The relationships were complex to say the least.
I find it difficult to be a Canadian at times because we are facing up to our history in ways many other countries are not. That is partly why you hear so much. It is also why the Canadian population today is feeling so much horror, guilt, and responsibility, even though we had nothing to do with setting up and running the schools.
It is why we are putting so much into reconciliation. We had a years long process of compensation for residential school survivors already, and the Royal Commission recommended the cemetery areas be studied. It is not a surprise that many children died of things like TB, childhood diseases, malnutrition etc. The churches who ran the schools were not the benevolent groups that were perhaps expected.
We are told we indirectly benefitted. I find it hard to see how, unless you sat that "white privilege" flows. I lived in a community with many indigenous people as a teen, and went to high school with kids from the residential school who came to my school for advanced subjects like sciences at higher grades. This was in the 1970s. We learned side by side.
I am not in any way saying that the residential school system was anything but a horror and huge mistake. So was letting the churches run them. But they had similar in the US and we do not hear anything really. I don't know about other countries with indigenous populations but it seems likely similar bad things happened.
