Vaudreuil-Soulanges Regional County Municipality

Vaudreuil-Soulanges is part of the St Lawrence Valley. Two million years ago the region was subject to a series of glaciations that covered much of North America. The last in the series was the Wisconsin glaciation. The ice sheet weighed down the landscape. This created the depressions in the land that created the basins for Lake Saint-Louis, Lac des Deux-Montagnes and Lake Saint-Francis. As the ice sheet eroded, the region was mostly submerged 12,000 years ago by an inland saltwater sea known as the Champlain sea. Once the glacier was melted, the land rose again, pushing the saltwater into the sea. 10,000 years ago the body of water, now a fresh water lake, has been named by scholars as Lake Lampsilis.

During the French colonial period, the region of New France was divided into several seigneuries populated by French colonists.{{Cite web|url=http://www.chlapresquile.qc.ca/histo/rubriques-historiques.html|title=Centre d'archives de Vaudreuil-Soulanges - Rubriques historiques}}

• Canton Newton founded in August 1791 (modern day Sainte-Justine-de-Newton, not part of the seigneurie system, was modeled after British township system){{cite web|url=http://www.archivesvs.org/histo/rubriques-historiques/newton.html|title=Centre d'archives de Vaudreuil-Soulanges - Canton de Newton}}:fr:Sainte-Justine-de-Newton{{Circular reference|date=December 2015}}

The seigneurial system was finally abolished in 1854, nearly a century after Great Britain took over the territory after defeating France in the Seven Years' War.

It is the only county in Quebec that lies both south of the Ottawa River and north of the St. Lawrence River. Great Britain wanted to keep most of the French-speaking, ethnic French population of the area within Lower Canada during the 1791 division of Upper and Lower Canada (precursors to the provinces of Ontario and Quebec). It is geographically isolated from the Montérégie region south of the St. Lawrence.

The name relates to the historical division of the area into two counties: Vaudreuil County -- (named after Pierre François de Rigaud, Marquis de Vaudreuil-Cavagnal, governor of New France) for the communities along the Ottawa River, and Soulanges County -- (named after Pierre-Jacques Joybert de Soulanges from Soulanges, Marne, France) for the communities along the St. Lawrence. Soulanges is a name of Québécois derivation, referring to its southerliness.

Since the RCM formation on 14 April 1982, the division of the county into "Vaudreuil" and "Soulanges" is still salient. The "Vaudreuil" area (consisting of the municipalities of Vaudreuil-Dorion, Saint-Lazare, Hudson, L'Île-Perrot, and others) is closer to Montreal. It is more suburban, populous, and economically and ethnically diverse. By contrast, the Soulanges area (including the municipalities of Saint-Polycarpe, Saint-Zotique, Coteau-du-Lac, Rivière-Beaudette and Les Coteaux) is predominantly rural, agricultural, and ethnically French-Canadian.

Owing to the county's geographic isolation within Quebec, and its growing population as a suburb of the city of Montreal, Elections Canada assigned the electoral district to the county in 1997.

There are 23 subdivisions within the RCM:
