Before you settle on a new semi-detached home near Chambly, it pays to compare the two towns honestly: living in Sainte-Julie or Chambly does not make for quite the same daily life, even if many landmarks look alike.

The two towns have almost the same population, both belong to the Montreal Metropolitan Community and both fall under the same school service centre. Yet they differ in setting, history and housing stock.

Here is what the public data shows, with no spin. It is up to you to decide what matters most for your family.

Two towns of the same size, two profiles

Population: 31,870 residents in Chambly and 30,981 in Sainte-Julie as of July 1, 2025, according to preliminary estimates from the Institut de la statistique du Québec;
Land area: 25 km² in Chambly, nearly double in Sainte-Julie (48.5 km²), which makes Chambly roughly twice as dense;
Age: a median age of 39.6 in Chambly and 44.4 in Sainte-Julie in the 2021 Census, with 14.3% aged 65 and over on one side and 18.0% on the other;
Ownership: 74.2% of households own their home in Chambly, 79.8% in Sainte-Julie;
Region: Chambly belongs to the Vallée-du-Richelieu regional county municipality, Sainte-Julie to Marguerite-D'Youville.

If you are weighing living in Sainte-Julie or Chambly, these gaps mostly say this: Chambly is younger and denser, Sainte-Julie more spread out and a little older.

What you would leave behind in Chambly, about 27 minutes away

Chambly has a heritage few towns in the region can match:

Fort Chambly, a stone fort from 1711 standing by the rapids, which the town describes as the only fort in the greater Montreal area;
the Chambly Canal and its nine locks, lined by a trail of more than 20 km to Saint-Jean-sur-Richelieu that is part of the Route verte;
the Chambly Basin, Parc des Rapides and the Gervais-Désourdy nautical centre;
Parc naturel des Ruisseaux, the town's largest park at 47 hectares, and a 52 km cycling network;
the Pôle culturel, which houses the library and the Emma-Albani concert hall, not to mention the Saturday-morning market at Parc des Ateliers in summer.

None of it disappears, though: from Geoffrion Street, Fort Chambly is 28.8 km away, or about 27 minutes without traffic.

What you would find in Sainte-Julie

the Vilamo neighbourhood, which the Town of Sainte-Julie describes as a 33.5-hectare area around the Vallée-du-Richelieu golf course, with 15% set aside for community and recreational space;
shops and services within walking distance: medical services, a public market, restaurants, a pharmacy and a Caisse Desjardins;
Espace Tonik, a members-only community sugar bush, with a three-year free membership according to beacite.com;
Mont Saint-Bruno: the ski centre is 8.8 km from Geoffrion Street, about ten minutes, with the national park right next to it;
a cycling network of more than 40 km and, since October 5, 2026, a BIXI station at Parc Arthur-Gauthier.

BÉAcité's 50 lots line Geoffrion and Bissonnette streets within it, with two parks and a retention pond included in the site plan. Nearby, Promenades St-Bruno and Quartier DIX30 round out the shopping options.

What stays the same

the school service centre: the Patriotes, in both towns. In Sainte-Julie, it runs seven elementary schools and École secondaire du Grand-Coteau; which school a child attends depends on the address;
free local buses, for everyone and at all times, in Chambly as in Sainte-Julie;
the Montreal Metropolitan Community, which both towns are part of.

In other words, a family that moves keeps the same public school network and the same free local bus service, two things that count in both a budget and a schedule.

Living in Sainte-Julie or Chambly: what about housing and the market?

The two housing stocks are not the same age. In Chambly, 33.2% of dwellings date from 2006 to 2021; in Sainte-Julie, 43.2% were built between 1981 and 2000, and only 10.7% between 2006 and 2021. Chambly also has more condominiums (18.5% of dwellings, against 11.5%) and slightly more semi-detached houses (7.5%, against 5.8%).

On prices, the most useful recent figure comes from Centris for the third quarter of 2026: a median resale price for single-family homes of $740,000 in Chambly and $690,000 in Sainte-Julie. Handle it with care, though: these are resales of every kind, based on few transactions (55 and 33 sales), and over the last four quarters the two medians are almost identical. It is in no way the price of a new semi-detached home at BÉAcité.

Daily life: the drive, work and free time

Commuting habits differ too. In the 2021 Census, 43.9% of Chambly commuters spent 30 minutes or more getting to work, against 30.2% in Sainte-Julie, and 6.5% took public transit, against 3.8%.

For a job in downtown Montreal, moving makes almost no difference: without traffic, Central Station is about 30 minutes from Chambly city hall and about 32 minutes from Geoffrion Street. Between the two towns, allow about 26 minutes by car, and no bus links them without a transfer.

For public transit, each town has its own park-and-ride: in Chambly, the one at the entrance to town, at the corner of boulevards Fréchette and Brassard, is free for exo riders; in Sainte-Julie, the local one is a few minutes from Vilamo, with buses to the Longueuil metro. Within Vilamo, every home is less than 300 m from a bus stop.

If you can work from home part of the time, the equation changes: our article on finding a house with home office near Chambly shows where a workspace can go.

Conclusion

Living in Sainte-Julie or Chambly means choosing between two towns of the same size that share a public school network, free local buses and a place in the metropolitan community. Chambly offers its fort, its canal and its basin; Sainte-Julie, the Vilamo neighbourhood, the golf course next door and Mont Saint-Bruno close by. Roughly half an hour apart, nothing forces you to give up one entirely to enjoy the other.
