The High-Canada was a Province of the British Empire, created in 1791 by the Acte constitutional and formed by the geographical and political separation of the territory of the province of Quebec. This one, with the Low-Canada (southern and is of current Quebec), will be the embryo of the territory of the Canada. High-Canada existed on the legal and political level of 1791 until the adoption of the Acte of union in July 1840.

High-Canada was characterized by its English lifestyle faithful to the British Couronne, where the civil and criminal laws were English. This division ends up creating a cold between two Canadas, where the cultures English and French clashed.
