Châteauguay (English:/ˈʃætoʊɡeɪ/SHAT-oh-gay,[6]French:[ʃɑtoɡɛ],locally[-ɡe]ⓘ) is anoff-island suburb ofMontreal, in southwesternQuebec, located on both theChâteauguay River andLac St-Louis, which is a section of theSt. Lawrence River. The population of the city of Châteauguay at the2021 Census was 50,815, and thepopulation centre was 75,891.[4][5]

The land was first given to Charles Lemoyne by the governor ofNew France at the time, theComte de Frontenac with the intention of setting up aseigneurie in the area.[citation needed] Afterwards the seigneurie was assumed by Zacharie Robutel de la Noue in 1706. In 1763France relinquished its claims in Canada and Châteauguay was now under British mandate. The seigneurie was bought by Marguerite d'Youville, a founder of the Quebec religious society theGrey Nuns in 1765 and 10 years later construction began on the Church of Saint-Joachim.[citation needed]
Châteauguay played an important part in thecolonial history of North America. With the United States having declared war on Britain in 1812, Châteauguay was seen as little more than a good vantage point to post troops to defend Montreal against an invasion.[citation needed] This prong of the American advance on Montreal ended with theBattle of the Châteauguay, where on October 26, 1813,Lieutenant Colonel Charles de Salaberry succeeded in halting the American force of 4,000 advancing on Montreal with only some 400 troops, mostly French-Canadian and 170Kahnawake Mohawk warriors. The second American incursion towards Montreal was defeated shortly after atCrysler's Farm on November 11.[citation needed]
During theLower Canada Rebellion, Châteauguay was the scene of a notable action involving thePatriote movement. In November 1838, members of the rebel group, including some of their leaders, were arrested: François-Maurice Lepailleur, who was later exiled toAustralia, and two natives of Châteauguay, Joseph Duquet and Joseph-Narcisse Cardinal, both of whom were later hanged at Au-Pied-du-Courant Prison and subsequently interred beneath a monument to the Patriotes at Notre-Dame-des-Neiges Cemetery in Montreal.[7]
The actual village of Châteauguay was created in 1855, after the abolition of the seigneurie system in Quebec by the United Province of Canada.[8] Later on the city annexed two neighbouring districts, Châteauguay-Heights (1968) and Châteauguay-Centre (1975). In 1982, with the passage of theLoi sur l'aménagement et l'urbanisme, Québec, the city became part of theRoussillon Regional County Municipality.

The Châteauguay Police have more than 130 police officers. Their duties include investigations, crime prevention and routine city patrols. The force also participates in many community efforts. The majority of theseoutreach programs are aimed at Châteauguay youth and focus on the prevention of drug and alcohol use which is widespread among the youth (up to 78% of the teens have used a drug on the course of last month according to a survey). The force, originally having onlyjurisdiction within the city limits expanded its jurisdiction over the nearby cities of Léry, Mercier, Beauharnois and Saint-Isidore between 2002 and 2007 through agreements between the municipalities. However, Mercier set up an independent policing system in 2019.
Since 1984, Châteauguay has been home to one of the largestHVDC-back-to-back stations in the world with an operating voltage of 140 kV and a maximum transmission rate of 1000 MW.

Public transportation is assured byCITSO (Conseil Intermunicipal de Transport du Sud-Ouest). They run two Châteauguay-Angrignon loop bus routes circulating in opposite directions. A city minibus transfers commuters from the western part of the suburb to the downtown, where the other off-peak routes pass. During rush hours, more bus routes connect the various neighbourhoods with theAngrignon bus terminal and metro station. A special express bus route connects western Châteauguay and the ChâteauguayPark-and-ride with downtown Montreal, only during rush hours. A reserved lane onHighway 138 eastbound makes the connection significantly faster when theMercier Bridge is congested. The Châteauguay public transit system also offers aTaxi-Bus service which allows those people who live outside of the normal bus routes to, by way of transfer, use ataxi funded by CITSO to drop them off at specific points in the city usually within walking distance of their residence.
The majority of the education institutions within Châteauguay are public, with the exception of Collège Héritage. A small list of Châteauguay schools includes:
NOVA Career Centre for adult students recently established itself in a building adjacent to Howard S. Billings. It was previously located in the school building.
During the 1980s, three English elementary schools became French due to a demographic shift[citation needed]:
