Lordship of Lac-des-Deux-Montagnes

The seigneury of Lac-des-Deux-Montagnes was located northwest of lac des Deux Montagnes, hence its name.

The act of ratification was issued some 16 years later, in 1733, by Governor Beauharnois, however with an enlargement of the area of 40%.

The Mohawks dispute the ministry's claim that the Sulpicians are the "full owners and in perpetuity" of the entire seigneury "and the rights of the natives are limited to the lands they occupy, excluding the hunting grounds.

They argue that the Treaty of Paris, the Treaty of Oswesgatchie and the Royal Proclamation recognize their rights over the entire seigneury and that their rights were not protected by Canada, the Mohawks never having been informed of the land transactions relating to the seigneury.

A cheese produced by the Fromagerie of Oka bears the name the Seigneurie du Lac-des-Deux-Montagnes.
