Saint-Jean-sur-Richelieu (about 101,000 people), Chambly (about 32,000) and Carignan (about 12,700) line the Richelieu River 35 to 40 km south and southeast of Montreal, and Landian works across all three with licensed local agents. Sellers list on the Centris/MLS with a licensed local agent for one flat fee set by the home's price, not a commission: $5,999 flat for a home around $650,000. $6,999 flat for a home around $750,000. $9,999 flat for a home around $1,000,000. The fee is shown before you meet the agent, written into your agreement, and paid only at closing.

Living in Saint-Jean-sur-Richelieu, Chambly and Carignan
Three towns joined by the Richelieu and a 20 km canal path: a regional capital with an old town, a fort town on its basin and the fastest-growing of the three, plus the newer neighbourhoods of Saint-Luc.

Saint-Jean-sur-Richelieu
Old Saint-Jean, the river and the balloons
Saint-Jean-sur-Richelieu is Quebec’s 11th-largest city, about 40 km southeast of Montreal and some 30 km from the U.S. border. Its story starts with Fort Saint-Jean, built in 1666-1667 by the Carignan-Salières regiment; the fort withstood a 45-day American siege in 1775, and since 1952 its grounds have held the Royal Military College Saint-Jean. Canada’s first public railway opened here on July 21, 1836, running about 23 km to La Prairie, and the city says that by the middle of that century Saint-Jean was the most important inland port in Quebec and Canada.
Old Saint-Jean backs onto the river. Rue Richelieu, called rue Front until 1873, was rebuilt after the great fire of June 18, 1876; the 1858 market hall on Place du Marché now holds the Musée du Haut-Richelieu, with a public market on Wednesdays and Saturdays in season, and the church of Saint-Jean-l’Évangéliste became a cathedral in 1934. Lock No. 9 Park, at the Saint-Jean end of the canal, sits beside the shops and restaurants. Each August the International de montgolfières fills the sky from the city’s airport: the city counts more than a hundred balloons, two flights a day around 6 a.m. and 6 p.m. when the weather allows, and calls it Canada’s largest gathering of hot-air balloons, held since 1984.
Today’s Saint-Jean-sur-Richelieu was formed on January 24, 2001 from five municipalities, Saint-Jean-sur-Richelieu, Iberville, Saint-Luc, L’Acadie and Saint-Athanase, which are now sectors of the city. Saint-Luc, close to the highways and to Montreal’s South Shore, has drawn families and commuters, the city says, and has a growing commercial area and farmland that runs to the edge of the South Shore. QPAREB put its single-family median, with L’Acadie, at $655,000 in the third quarter of 2026, against $540,000 in the Saint-Jean sector.
Across the river, Iberville grew around its old buildings and the Vieux-Iberville commercial strip; a pottery opened there in 1876 and ran until 1930. L’Acadie takes its name from Acadian exiles who settled along the Rivière L’Acadie from 1763, and its church, presbytery and sexton’s house form an ensemble the city calls unique in Quebec. Saint-Athanase is the country belt around Iberville, with farms, agritourism and newer housing developments.

Chambly
A stone fort at the foot of the rapids
Chambly dates itself to 1665, when Captain Jacques de Chambly of the Carignan-Salières regiment built a wooden fort at the foot of the Richelieu rapids; Samuel de Champlain had reached the basin in 1609. The stone fort that replaced it in 1709, restored, is a national historic site 35 km south of Montreal and, Parks Canada notes, the only fort in Greater Montreal, with exhibits, a guided outdoor tour and picnic spots by the rapids.
The town sits on the Chambly basin, where the canal’s first locks climb from the river. Parc des Ateliers, a wide lawn near downtown just upstream of Lock No. 3, is made for picnics, avenue Bourgogne runs through the historic centre, and the Parc naturel des Ruisseaux, at 47.28 hectares the city’s largest park, has 5 km of walking trails and 6 km of cross-country ski trails. Downtown is adding homes too: the city lists a 146-unit rental building on avenue Bourgogne and 126 units of four to seven storeys on boulevard Fréchette.
Carignan is the fastest-growing of the three: 9,462 residents in 2016, 11,740 in 2021 (up 24.1%) and 12,657 in Quebec’s 2026 decree. It is mostly houses. Single-detached homes are 80.4% of its occupied dwellings, nine in ten households own, and 22.3% of its homes were built between 2016 and 2021 (2021 Census).
Its median household income, $122,000 in 2020, was the highest of the three, and it has room: about 189 people per square kilometre, against about 1,254 in Chambly. The Chambly Canal path runs through Carignan on its way to Saint-Jean, and the town takes in Île Goyer, Île aux Lièvres and Île Demers as well as the Carignan-sur-le-golf neighbourhood near Route 116.
What the numbers say about the Richelieu Valley, 35 to 40 km from Montreal.
More house for the money
QPAREB’s third-quarter 2026 median for a single-family home was $590,000 in Saint-Jean-sur-Richelieu, up 7% on a year earlier, and $718,000 in the Chambly area, against $811,000 on the Island of Montreal (Centris data).
A city past 100,000
Quebec’s 2026 population decree puts Saint-Jean-sur-Richelieu at 100,967 residents, up from 97,873 at the 2021 Census. Carignan grew 24.1% and Chambly 8.0% between 2016 and 2021, against 4.1% for Quebec (Statistics Canada).
A finished highway
The last section of Autoroute 35 opened on September 3, 2025, so the drive between Montreal and the U.S. border is now on four divided lanes (Government of Quebec).
The REM next door
Saint-Jean-sur-Richelieu’s route 96 buses now run to the REM’s Panama and Brossard stations, where the city says trains leave every 3.5 minutes at rush hour and every 7 minutes the rest of the day.
What homes here look like
Saint-Jean-sur-Richelieu is a mix: half its occupied homes (50.1%) are single-detached houses and 36.8% are apartments in buildings under five storeys, and 60.0% of households own. Chambly is 54.5% single-detached with 18.5% of its homes in condominiums, and Carignan is 80.4% single-detached (2021 Census).
The census medians cover every owner-occupied home in 2021 ($348,000 in Saint-Jean-sur-Richelieu, $400,000 in Chambly and $500,000 in Carignan), so today’s sale prices run well above them: QPAREB’s third-quarter 2026 medians were $590,000 for a single-family home and $374,000 for a condo in Saint-Jean-sur-Richelieu, and $718,000 and $420,000 in the Chambly area.
Older homes
18.2% of Saint-Jean-sur-Richelieu’s homes were built in 1960 or earlier (2021 Census). The city has evaluated 300 heritage buildings, and work in Vieux-Saint-Jean, Vieux-Iberville and Vieux-L’Acadie falls under its architectural review rules (PIIA), so ask before you plan changes.
Plexes
Duplexes, triplexes and larger plexes are a category of their own in QPAREB’s Centris statistics. The 12-month median plex price to September 2026 was $625,000 in Saint-Jean-sur-Richelieu and $730,000 in the Chambly area.
Condominiums
Condos are 18.5% of Chambly’s homes and 10.1% of Saint-Jean-sur-Richelieu’s (2021 Census). Ask the syndicate of co-owners for its minutes, budget and contingency fund before you make an offer.

Schools
Two school service centres run the French-language public schools. The Centre de services scolaire des Hautes-Rivières, based in Saint-Jean-sur-Richelieu, teaches more than 21,000 young students in 34 preschool and elementary schools, another elementary school, a specialized school and seven secondary schools. Chambly and Carignan belong to the Centre de services scolaire des Patriotes, which lists eight schools in Chambly for 2026-2027, École secondaire de Chambly and École secondaire le Tremplin among them, and three in Carignan: du Parchemin, Carignan-Salières and du Boisé.
English public schools belong to the Riverside School Board. St. Johns School (elementary and high school) gives priority to Saint-Jean-sur-Richelieu, including Saint-Luc, Iberville, L’Acadie and Saint-Athanase, while William Latter School (elementary) and Heritage Regional High School serve Chambly and most of Carignan. In Quebec, school is in French unless a child is eligible for English instruction under the Charter of the French language, so check eligibility before you pick a home for a school.
By car, Saint-Jean-sur-Richelieu is about 20 minutes from the Champlain Bridge, according to the city, and Chambly sits close to Autoroutes 10 and 35. Most people drive: the car is the main way to work for 91.7% of commuters in Saint-Jean-sur-Richelieu, 87.3% in Chambly and 94.6% in Carignan, and 39.4% of Saint-Jean’s commuters get to work in under 15 minutes; 61.4% of them work in the city itself (2021 Census).
For transit, Saint-Jean-sur-Richelieu runs its own route 96 to the REM: the 96 A by Autoroute 30 to Panama station, and the 96 E express by boulevard du Séminaire Nord and the 96 S super express by Autoroute 35 to Brossard station, with service to Brossard seven days a week, evenings included. The direct buses to Montreal have ended. In Chambly, Richelieu and Carignan, exo runs the buses and shared taxis, local routes inside the three towns charge no fare, and exo riders can park at the lot at boulevards Fréchette and Brassard at the entrance to Chambly.
The Chambly Canal opened in 1843 to take boats around the Richelieu rapids between Saint-Jean and the Chambly basin. Its nine locks and its bridges still work by hand, and a motorboat now makes in 3 to 5 hours a trip that took a towed barge 10 to 12. The old towpath is the outdoor spine of the area.
The canal path
20 km between Chambly, Carignan and Saint-Jean-sur-Richelieu, flat and unpaved, away from car traffic for 16 km, and part of the Route verte 1 and the Trans Canada Trail. It is maintained from April 15 to November 15, with snowshoeing and cross-country skiing in winter.
Longer rides
With La Montérégiade and La Route des Champs, the canal path makes a 110 km loop, and the Véloroute Gourmande links Montreal and Sherbrooke. Saint-Jean-sur-Richelieu adds 44.1 km of marked bike lanes.
Nature parks
Chambly’s Parc naturel des Ruisseaux (47.28 ha), Saint-Jean-sur-Richelieu’s Parc naturel des Parulines (26 ha, the city’s first nature park) and the 21-hectare Parc naturel Carillon in the Saint-Eugène neighbourhood.
On the water
Boats lock through the canal in season, canoes, kayaks and paddleboards launch with a navigation sticker, and La Route Bleue, a paddling route, follows part of the canal. Parks Canada’s red chairs dot the banks.

The river, the spring and flood maps
The Richelieu crosses Saint-Jean-sur-Richelieu from south to north, and the city lists floods from heavy rain or the river overflowing among the disasters most likely to happen there. In spring 2011, record precipitation and snowmelt pushed Lake Champlain and the Richelieu over their banks; the lake stayed above flood stage for 67 days, from April 13 to June 19, and close to 4,000 homes were damaged in the two countries (Lake Champlain Basin Program).
Quebec’s modernized rules for flood zones, shorelines and littoral zones replaced the transitional regime on March 1, 2026, and new-generation flood maps are being published sector by sector. Before you buy or list near the water, look the address or lot number up on the Government of Quebec’s map, confirm the rules with the city, and ask your insurer early about overland flood coverage. Saint-Jean-sur-Richelieu also sends text alerts during the spring flood.

Moving for the river, the canal or the room? Tell us which towns you are watching and you are matched with a licensed buyer’s agent who works the Richelieu Valley. In Quebec, a notary checks the title, draws up the deed of sale from your accepted offer, holds the money in trust and registers the sale in the land register, and a mortgage must be signed before a notary. Budget for the transfer duty, the welcome tax: in 2026 Saint-Jean-sur-Richelieu and Chambly both charge 0.5% up to $62,900, 1% up to $315,000, 1.5% up to $500,000 and 3% above, about $10,110 on a $650,000 home (our calculation).

Questions about Saint-Jean-sur-Richelieu and Chambly
How much does it cost to sell a house in Saint-Jean-sur-Richelieu, Chambly or Carignan with Landian?

It is shown before you meet your agent, written into your agreement, and paid from your proceeds at closing. Nothing upfront.
Is the fee the same in Saint-Jean-sur-Richelieu, Chambly and Carignan?
Yes. The schedule is set by the home's price, not by the town, so a home at the same price pays the same flat fee anywhere in Quebec. Under $500,000, the fee you see is final. From $500,000, an agent may propose a different fee before you choose them, with a reason and always under 1% of your expected price. You can say no and wait for an agent who accepts.

How do I get to Montreal without a car?
From Saint-Jean-sur-Richelieu, take a route 96 bus to the REM: the 96 A to Panama station, or the 96 E or 96 S to Brossard station, where the city says trains leave every 3.5 minutes at rush hour. The direct buses to Montreal have ended. In Chambly, Richelieu and Carignan, exo runs the buses, and local routes inside those towns charge no fare.
How much is the welcome tax in Saint-Jean-sur-Richelieu or Chambly?
Both cities use the same 2026 rates: 0.5% on the first $62,900, 1% up to $315,000, 1.5% up to $500,000 and 3% above that, on the higher of the price and the assessed value times the comparative factor. That is about $10,110 on a $650,000 home and $20,610 on a $1,000,000 home (our calculation). The buyer pays it in one payment; Saint-Jean-sur-Richelieu sends the bill one to three months after the sale is registered.
How do I check whether a home is in a flood zone?
Search the address or lot number on the Government of Quebec’s flood-zone map, which shows the older municipal maps and the new-generation maps published since the modernized rules took effect on March 1, 2026, then confirm the rules with the city or the MRC. The Richelieu flooded for weeks in 2011, so ask the seller about past water and your insurer about overland flood coverage early.
When is the balloon festival?
In August, at the Saint-Jean-sur-Richelieu airport, every year since 1984. The city counts more than a hundred balloons and two flights a day, around 6 a.m. and 6 p.m. when the weather allows, along with hundreds of shows, and calls it Canada’s largest gathering of hot-air balloons.
