without the national history of slave ownership and post civil war social engineering
I don't know if you know this, but slavery was never outright banned in Canada. It was decided through case law. There may not have been as many slaves up North, but it's not like they literally never had any. The French enslaved natives just like the British did, and both of those countries claimed parts of Canada.
Canada might have this reputation today of loveable, harmless hosers from the North, and you might even imagine Rick Moranis when you think of Canadians, but their country was founded on racism just as much as ours was.
They had forced sterilization policies for First Nation women... just like we did.
The RCMP has a long history of starlight tours. A starlight tour is basically where the RCMP would take a First Nations person out to the middle of nowhere in winter and abandon them there, often taking their clothes. These people would be forced to walk home in the freezing cold.
