As a Canadian, I feel like the atrocities of the United States are often well publicized but those of Canada are swept under the rug. Can someone shed light on how much truth is present in this article and what other eyebrow-raising to unforgivable occurrences have happened in Canadian history that aren't typically taught in school?
There's the WWII Japanese internment camps in western Canada. They made a point to teach this is high school socials in Vancouver but I don't know if it's well-taught in the east. There were also the harsh conditions for the Chinese while building the Canadian Pacific Railway but I don't know if you would consider that a straight-up atrocity.
Additionally, there is the Komagata Maru incident where a boat of Indian (hopeful) immigrants was denied landing in a Vancouver port in 1914 and the similar MS St. Louis incident in 1939 where Canada (as well as the U.S. and Cuba) denied landing of a ship of refugees escaping Nazi persecution that eventually returned to Europe.
Finally, off the top of my head, there is the ongoing saga of resolving issues from Canadian residential schools which, to sum up briefly, (in some cases) maltreated some of its residing First Nations students leading to abuse or death. It's been a cause of sadness for many First Nations people in Canada.
If you wanted any wartime atrocities, however, nothing comes to mind.
The story of land deals with natives is really horrific from a modern perspective. The Canadian Government bullied native leaders into giving up land and subsequently renegotiated on a number of occasions taking more and more land.
At the moment, there are a few events that will be historically important as Canada's role abroad changes. We've gone from a dormant, sleepy landmass into something more noticeable. For ex. our role in Afghanistan, Arctic Protection, Canadian companies abroad
Only the last one would count as an atrocity. It is not the only company behaving questionably.
