List of joint premiers of the Province of Canada

This is a list of the joint premiers of the Province of Canada, who were the heads of government of the Province of Canada from the 1841 unification of Upper Canada and Lower Canada until Confederation in 1867.

Each administration was led by two men; after Sydenham's Ministry, one from Canada West (now Ontario) and one from Canada East (now Quebec). Officially, one of them at any given time had the title of Premier, while the other had the title of Deputy.
