The Legislative Assembly of Lower Canada was the lower house of the bicameral structure of provincial government in Lower Canada until 1838. The legislative assembly was created by the Constitutional Act of 1791. The lower house consisted of elected legislative councillors who created bills to be passed up to the Legislative Council of Lower Canada, whose members were appointed by the governor general.
The lower house was dissolved on March 27, 1838 following the Lower Canada Rebellion and Lower Canada was administered by an appointed Special Council. With the Act of Union in 1840, a new lower chamber, the Legislative Assembly of Canada, was created for both Upper and Lower Canada which existed until 1867, when the Legislative Assembly of Quebec was created.
