Montérégie (French pronunciation: ​[mɔ̃teʁeʒi]) is an administrative region in the southwest part of the Canadian province of Quebec. It includes the cities of Boucherville, Brossard, Granby, Longueuil, Salaberry-de-Valleyfield, Saint-Jean-sur-Richelieu, Saint-Hyacinthe, Sorel-Tracy, and Vaudreuil-Dorion.

The region has a population of 1,442,433 (2011) and a land area of 11,131.32 square kilometres (4,297.83 sq mi), giving it a population density of 129.6 hab/km² (336/sq mi). It is the second most populous region of Quebec after Montreal. The majority of the population lives near the Saint Lawrence River, on the south shore of Montreal.

Montérégie is known for its vineyards, orchards, panoramas, delicious products, and the Monteregian mountains. The region is both urban (second in terms of population in Quebec) and rural. The regional economy is based on agriculture and the production of goods and services. Tourism also makes up a significant portion of the economy.[citation needed]


Montérégie is named for the Monteregian Hills, which are in turn named for Mount Royal (Mont Royal in the original French). Montérégie was populated by the Iroquois when the French began to colonize here in the beginning of the 17th century.

Samuel de Champlain built several forts to protect the colonists against the Iroquois and against the English, who were colonizing New England to the southeast. N.B.: Jacques Cartier was the first European to "discover" Mont Royal, naming it in October 1535.[2]

Some of the battles which decided the destiny of Canada took place in Montérégie. Originally, the administrative territory of the Montérégie parishes were taken from the territory of the canonical Diocese of Saint-Jean-Longueuil.[citation needed]


The Montérégie comprises three administrative subregions, each consisting of its own Regional County Municipalities (RCM) or Equivalent Territories. The territorial administration of the region is conducted by three Regional Conferences of Elected Officers (French: Conférences régionales des élus) (CRE) separate and independent in their territory: Longueuil, Montérégie-Est (eastern RCMs) and Vallée-du-Haut-Saint-Laurent (western RCMs). Each sub-region is organized in the same way as other administrative regions of Quebec.

Native Reserves[edit]

The population of both of these reserves are majority-Mohawk, one of the historic Five Nations of the Haudenosaunee, or Iroquois League. Kahnawake was established south of Montreal in 1719 as a mission village. Akwesasne was established upriver by Mohawk leaders and their families in the mid-18th century, accompanied by French Jesuit missionaries. Akwesasne spans the boundaries of Canada and the United States, extending across the St. Lawrence River into New York State, where it is referred to as the St. Regis Reservation.
