E27: The Constitutional Act of 1791

The Constitutional Act 1791 (31 Geo. 3. c. 31) (French: Acte constitutionnel de 1791) was an Act of the Parliament of Great Britain which was passed during the reign of George III. The act divided the old Province of Quebec into Lower Canada and Upper Canada, each with its own parliament and government. It repealed the Quebec Act 1774. The act remained in force until 1841, when it was largely repealed by the Union Act, 1840, which reunited the two provinces into the new Province of Canada. Some provisions relating to the clergy reserves remained in force. The remaining provisions of the act were repealed over time, with final repeal in 1966.
