Updated October 2026
The Réseau express métropolitain (REM) has changed the way people get around on Montreal's South Shore, and many buyers ask us whether it serves Chambly. Let's be clear: the REM does not run to Chambly. Its South Shore branch, in service since July 31, 2023, ends in Brossard. Chambly does, however, have a direct bus link to the REM terminus, and that link, along with Highway 10, is what weighs in buying decisions.
Where Does the REM Actually Go on the South Shore?
On the South Shore, the REM has three stations, all located in Brossard: Brossard (terminus), Du Quartier and Panama. The line then crosses the river to Île-des-Sœurs and Central Station downtown. Longueuil, Saint-Hubert and Chambly are not served by the REM. The Brossard terminus station includes a park-and-ride lot of about 3,000 spaces, according to the City of Brossard.
How Chambly Connects to the REM
Since the REM opened, exo buses from the Chambly-Richelieu-Carignan sector that used to go downtown now run to the Terminus Brossard, where riders transfer to the REM. As of October 2026, exo connects Chambly and Carignan to the terminus with several routes in the 480 series, including one daily route and several peak-hour routes. In practical terms, a Chambly resident can reach downtown without a car, with a single transfer.
Transportation Options for Chambly Residents
Here is what is in place today for Chambly commuters:
- exo buses to the Terminus Brossard, with a REM connection to downtown
- exo buses to the Longueuil terminus (routes 680 and 681), with access to the Longueuil–Université-de-Sherbrooke metro station and Cégep Édouard-Montpetit
- Chambly bus terminus and park-and-ride, the starting point for local and regional routes
- exo train, Mont-Saint-Hilaire line: no station in Chambly, but the Saint-Bruno and Saint-Basile-le-Grand stations are a short drive away, with direct service to Central Station
- Highway 10 toward Brossard and Montreal, and Highway 35 toward Saint-Jean-sur-Richelieu, which meet at the Chambly–Carignan boundary
A Project to Watch: Reserved Lanes on Highway 10
On June 30, 2026, the Quebec government confirmed a major rehabilitation of Highway 10 between Highway 30 (Brossard) and Highway 35 (Carignan), adding a reserved lane of about 10 km in each direction for buses, taxis and carpools (2 or more occupants). These lanes will connect to the REM's Brossard terminus. More than 280 weekday bus trips, including those serving the Chambly area, are expected to use them. Full operation is planned for the end of 2030. For Chambly commuters, this is the most concrete change on the horizon.
The Chambly Real Estate Market by the Numbers
According to Centris data compiled for the city of Chambly for September 2026:
- Single-family homes: 20 sales, median price of $628,500 (average $703,800), about 31 days on market, sold on average at 98% of asking price
- Condominiums: 13 sales, median price of $420,000, about 71 days on market
- 70 single-family homes and about fifty condos listed for sale at month-end
For comparison, the median price of single-family homes sold in Brossard, the city served by the REM, was $729,750 the same month. Chambly therefore remains a more affordable option for families who work in Montreal, while still being connected to the REM by bus. These figures cover a single month and a small number of transactions: they show a trend, not a value for your property.
Areas That Attract Buyers
- Old Chambly: historic charm, close to the Chambly Basin and the Fort Chambly National Historic Site
- Along the Chambly Canal: access to the bike path along the canal and to the Richelieu River
- Areas near Highway 10: popular with commuters for quick access to Brossard and the REM terminus
"Not having a REM station in Chambly is not necessarily a disadvantage. With the bus to the Brossard terminus, residents keep good access to Montreal and the residential tranquility many buyers are looking for." - Marc Pouliot, RE/MAX Privilège Broker
Expert Advice for Buyers
As an experienced broker on Montreal's South Shore, I recommend that buyers consider Chambly a serious alternative to cities served directly by the REM. Single-family prices are more accessible than in Brossard, the quality of life is well established, and the bus link to the REM is already in place.
Before buying, check the distance to the stop for the exo route to the Terminus Brossard and its hours of service, and test your commute at the times you will actually travel. A personalized analysis of your situation will allow you to make an informed decision regarding your next real estate purchase in the region.
