A map I made of an Alternate Canada.
The timeline wasn't exactly my primary concern, but the idea was that Canada, at least the eastern parts of it, has a similar revolution to the American one against the British Empire, much later.
This results in the Dominion of Canada splintering into several republics: the main Republic of Canada which took with it most of New England, the Maritime Union which is more friendly with the British but still don't want to be ruled by them, and the independent state of Quebec which wants nothing to do with anyone of the Anglo-countries. The rest of Canada remains British as the Dominion of Borealia, with its capital in Winnipeg.
Somehow Vancouver becomes independent, and the Dutch get New Amsterdam back; like I said the timeline wasn't first on my mind. The fact the British still hold on to Borealia is more from their imperial pride that any logic.
