The Rebellions of 1837–1838, were two armed uprisings that took place in Lower and Upper Canada in 1837 and 1838. Both rebellions were motivated by frustrations with lack of political reform. A key shared goal was responsible government, which was eventually achieved in the incidents' aftermath. The rebellions led directly to Lord Durham's Report on the Affairs of British North America and to the Act of Union 1840 which partially reformed the British provinces into a unitary system and eventually led to the British North America Act, 1867, which created the contemporary Canadian federation and its government.

The Province of Lower Canada was a British colony on the lower Saint Lawrence River and the shores of the Gulf of Saint Lawrence (1791–1841). It covered the southern portion of the current Province of Quebec and the Labrador region of the current Province of Newfoundland and Labrador.
