Step-by-step explanation:
After the American Revolutionary War, many Loyalists who had hoped for a British victory decided to move to Canada to continue as British subjects rather than becoming citizens of the new United States. The influx of these Loyalists transformed Canada from being predominantly French to predominantly British. This movement of people post-revolution essentially helped shape the early population demographics and political landscape of both the United States and Canada. Additionally, it is noteworthy that during the American Revolution, the British did not succeed in convincing Canadians to join their cause against the revolutionaries, and likewise, future American hopes of a Canadian revolt during the war of 1812 also failed.
