The Pays d'en Haut (French: [pɛ.i dɑ̃ o]; Upper Country) was a territory of New France covering the regions of North America located west of Montreal. The vast territory included most of the Great Lakes region, expanding west and south over time into the North American continent as the French had explored. The Pays d'en Haut was established in 1610 and dependent upon the colony of Canada until 1763, when the Treaty of Paris ended New France, and both were ceded to the British as the Province of Quebec.
