Châteauguay is a dynamic suburban city on the south shore of Montreal, part of the Greater Montreal metropolitan community and one of the most significant Montérégie commuter cities. Located along the Châteauguay River at its confluence with the St. Lawrence, the city offers good Montreal access via Autoroute 30 and the Route 138 corridor.

Average home prices in Châteauguay are around $415,000, offering notably better value than comparable Montreal-north suburbs with similar infrastructure and services. The city has a population of approximately 50,000 and continues to grow as buyers seek south shore affordability.

Châteauguay has historical significance as the site of the Battle of Châteauguay (1813) — a pivotal War of 1812 engagement where 460 Canadian voltigeurs and Indigenous allies turned back 3,000 American soldiers. The battlefield is now a National Historic Site and point of local pride.

The city has a significant francophone population with a notable anglophone community. All major banks have branches: TD, National Bank, Desjardins, RBC, and Scotiabank serve Châteauguay. Digital banks like KOHO and EQ Bank are popular among young buyers who prefer mobile-first banking.

The droits de mutation on a $415,000 home in Châteauguay is approximately $4,671 — no Montreal island surtax applies here. The city is in Montérégie, not on Montreal island, meaning the additional 0.5% over $500,000 does not apply.
