Châteauguay has a population of approximately 53,000, making it the third largest city on Montreal’s South Shore and the 21st largest in Quebec. It lies on the shores of Lake Saint-Louis, about 25 minutes from downtown Montreal via the Mercier Bridge. Châteauguay is the fifth largest economic hub on the South Shore and the second largest in terms of jobs and businesses in the South Shore region, generating more than 14,000 local jobs within its territory.

Châteauguay offers a complete living environment that is particularly attractive to families thanks to its excellent public transportation system and comprehensive school network from kindergarten to high school. Residents enjoy remarkable heritage attractions, including the Moulin de l’île Saint-Bernard, built around 1688 and recognized as one of the oldest mills in North America. Île Saint-Bernard itself, a former seigneurial hill purchased by the city in 2011, offers an exceptional natural site bordered by Lake Saint-Louis and the Châteauguay River, with hiking trails, green spaces, and opportunities for various water activities such as kayaking, canoeing, and paddleboarding.

The Châteauguay real estate market is characterized by its affordability and architectural diversity. Single-family homes with three or four bedrooms account for nearly two-thirds of the housing stock, creating a sought-after family-friendly residential environment. Neighborhoods near Île Saint-Bernard and those offering waterfront access are particularly coveted for their enchanting setting. This combination of relatively affordable prices, proximity to Montreal, and comprehensive infrastructure makes Châteauguay a wise choice for young families and professionals who work in the city but are looking for a peaceful residential environment with a strong sense of community.
