The joint premiers of the Province of Canada were the heads of government of the Province of Canada, from the 1841 unification of Upper Canada and Lower Canada until Confederation in 1867.
Following the abortive Rebellions of 1837, Lord Durham was appointed governor in chief of British North America. In his 1839 Report on the Affairs of British North America, he recommended that Upper and Lower Canada be united under a single Parliament, with responsible government.
