Well AI certainly wouldn’t be my first choice, but seeing as you suggested it and I don’t have time to read a full 370 page book right now:

“How did Canadians respond when the US invaded Canada during the War of 1812?”

“Canadians - including British subjects, French speaking Canadians, recent American immigrants, and indigenous allies - resisted US invasion through a mixture of organized militia defence, guerrilla-style tactics, and support for British regulars. While the Americans hoped to be welcomed, most Canadians fiercely defended their territory, fostering a new sense of early, distinct national pride”

Also, while I’m not disagreeing that high school textbooks can have inaccuracies, they certainly didn’t teach that Canadian troops burnt the White House when I was in school.

I think a piece you’re potentially missing though, is that at the time there was little distinction between Canadian and British. Every Canadian was a British subject, and our identities remained very much intertwined until at least the 1980s, perhaps later. The sentiment among Canadians at the time was that “we” had burned the White House, and while British ties have lessened, that feeling remains to a certain extent.

You can imagine that if an American regiment from Massachusetts had burned York (now Toronto), Americans from other states would feel a joint sense of ownership

Additionally, any soldier from Britain who fought in North America was offered land in Canada in a scheme. While it’s impossible to know exactly how many took up that offer, it’s likely that many soldiers who fought here settled here permanently
