Could you be a bit more specific? Canada has a long and dark history of oppression when it comes to our first Nations Inuit and Metis people. On the east coast most of the first Nations people were wiped out by early settlers and throughout Canada we have had relocation, forced conversion, and apartheid like conditions for first Nations people. Recently the truth and reconciliation commission came out with their findings focused on the residential school system in Canada where children were taken from their homes and sent to incredibly inhumane "schools" where the goal was to remove their culture and "assimilate" them this system was begun in about 1890 and continued until 1998 (although I believe it reached its peak around 1940 to 1950)

I am an aboriginal studies major so I'll do my best so answer any questions you have

I was just looking into the recommended book list on the sidebar of this sub, and in the Canadian section there's a book called "Makuk: A New History of Aboriginal-White Relations" by John Sutton Lutz. It's about how the relationship between natives and European settlers was actually generally productive and cooperative until the 1950's when the drive to "civilize" them started. I haven't read it yet, but it sounds like it might be up your alley.
