President Trump allegedly made the following statement about Canada:
“Didn’t you guys burn down the White House?”

The way I recall it, the war of 1812 was fought mainly between Great Britain and the US. But Canada was certainly one of Great Britain's allies in that conflict and did participate in military actions in defense of the British crown's interests in North America.
Therefore, in this context the phrase "you guys" does in fact include Canada.
