Longueuil Real Estate Market by Sector: Q3 2026

Added together, the three pages Centris devotes to Longueuil count 540 residential sales in the third quarter of 2026, a quarter of the 2,154 sales on the South Shore. The median price of a single-family home shows 0% change over one year: $625,000 in Vieux-Longueuil, $587,500 in Saint-Hubert. What is moving is the number of transactions, down 25% in Saint-Hubert. Here are the three boroughs, their four neighbouring cities and what is confirmed on Taschereau, the metro and the REM.

Longueuil’s three boroughs compared

Centris does not publish a page for the city as a whole, only one per borough. There is therefore no median price for Longueuil, and none can be calculated from the three: medians do not add up.

Changes are compared with the third quarter of 2025; changes in days, which refer to single-family homes, are expressed in days. “n.p.”: not published by Centris, because there are too few transactions.

Saint-Hubert loses a quarter of its sales. It is the steepest drop of the seven territories presented here, and it is condos that fall the most there: 60 sales, -44%. Yet single-family homes sell there in 29 days on average, the shortest selling time in this article, and the supply of houses is shrinking: 134 active single-family listings, 10% fewer than a year earlier. Local context: real estate broker in Saint-Hubert.

Vieux-Longueuil accounts for more than half of the sales. 283 out of 540, with as many condos as single-family homes (116 each) and 51 plexes. The single-family selling time there lengthens by 13 days, to 35, the largest increase in the table, without the median moving. See real estate broker in Old Longueuil.

In Greenfield Park, supply doubles. Sales barely drop (41, -4%), but active listings rise to 73, 102% more than in summer 2025. The 28 single-family homes sold are not enough for a quarterly median; over four quarters and 109 sales, it stands at $570,062.

Longueuil condos and plexes by borough

Source: the same Centris pages, third quarter of 2026. Quarterly medians, except where marked “over 4 quarters”, which refers to the Centris “Cumul 4 derniers trimestres” column (last four quarters combined).

Condos wait longer. In Vieux-Longueuil, 221 active condo listings (+32%) and 47 days on the market (+7); in Saint-Hubert, 137 active listings (+52%) and 45 days (+16). The two medians, $3,500 apart, both remain below the South Shore median.

South Shore plexes sell mostly in Longueuil. Over four quarters, the three boroughs total 394 of the 678 plexes sold on the South Shore, or 58%, including 259 in Vieux-Longueuil alone. On the rental side, the October 2025 CMHC survey, the most recent one, measured a vacancy rate of 2.1% in the city of Longueuil, compared with 2.9% for the metropolitan area.

Longueuil and its neighbours in the agglomeration

According to the City, Boucherville, Brossard, Saint-Bruno-de-Montarville and Saint-Lambert are part of the Longueuil agglomeration, not of the city itself. They serve here as a point of reference.

The gap with the neighbours is clear. The lowest published quarterly single-family median among the neighbours, $739,500 in Brossard, is $114,500 higher than the highest one published in Longueuil, that of Vieux-Longueuil. Brossard is also the only one to hold its number of sales: 291 transactions, unchanged. Among the other three, the drop ranges from 12% in Saint-Bruno-de-Montarville to 22% in Saint-Lambert. The Brossard, Boucherville and Saint-Bruno-de-Montarville pages describe each city.

The assessment roll ranks Longueuil the same way. On the agglomeration’s 2025-2026-2027 roll, which reflects the market as of July 1, 2023, the average value of a single-family home is $545,700 in the city of Longueuil, the lowest of the five cities, compared with $656,400 for the agglomeration; for a condo, $365,500 against $409,500. A roll average is neither a median nor a sale price: it can be compared from one city to another, not with the tables above.

What is weighing on the Longueuil real estate market

The policy rate. As of October 20, 2026, it stands at 2.25%, unchanged since the cut of October 29, 2025. The Bank of Canada’s next announcement is scheduled for October 28, 2026. To turn a $587,500 median into payments, the mortgage calculator gives you the order of magnitude; your mortgage broker sets the actual rate.

The APCIQ classification. For single-family homes, the APCIQ barometer for the third quarter of 2026 places every price range in its two Longueuil sectors in a seller’s market, over the last 12 months: from 1.5 to 4.1 months of inventory in the “Vieux-Longueuil” sector, which includes Greenfield Park, and from 2.1 to 6.7 months in Saint-Hubert. The APCIQ puts balance between 8 and 10 months. For condos, its October 14, 2026 release lists the South Shore among the areas that remain in sellers’ favour.

Transfer duties (the welcome tax). Longueuil applies 0.5% up to $62,900, 1% up to $315,000, 1.5% up to $630,100 and 3% above that. For a plex bought for $840,000, the Vieux-Longueuil median, that comes to $13,859 if the price serves as the base, including $6,297 on the 3% bracket. The base is the highest of the price, the consideration stated in the deed and the roll value multiplied by the comparative factor, 1.06 in 2026. The City publishes a 2026 transfer duty calculator; your notary confirms the amount.

New construction. According to CMHC, 406 housing units were started in the city of Longueuil from January to September 2026, including 376 apartments, compared with 1,015 in the same period of 2025. CMHC does not break these figures down by borough.

Taschereau, the metro and the REM: what is confirmed

Taschereau: a rapid bus service planned, a bus line in operation. The preliminary design vision presented on June 9, 2025 by Longueuil and Brossard opts for a rapid bus service, not a tram, between the Longueuil-Université-de-Sherbrooke terminus and the Panama terminus; the City of Brossard still classifies the project as “Planifié” (planned). What is already running is a bus line: according to the ARTM, metropolitan line 901 Taschereau, operated by the RTL, entered service on August 24, 2026. The ARTM’s 2025-2029 implementation plan has it linking the Longueuil terminus, the Panama REM station and terminuses in La Prairie, Candiac and Delson.

No yellow line extension in the plan. Longueuil is home to the terminus of the yellow line. Among the priority interventions in its 2025-2034 strategic plan, the ARTM counts only one metro extension: the blue line, scheduled for 2031.

The REM stops in Brossard. The REM lists three stations under “Agglomération de Longueuil”, all in service: Panama, Du Quartier and Brossard. Their addresses are all in Brossard; no station is in the city of Longueuil.

Espace Longueuil, near the metro. On June 16, 2026, the City selected Groupe Montoni for a complex in the metro sector: a convention centre, a hotel and some 620 housing units, 20% of them non-profit. The project remains conditional on final agreements; the City is considering a construction start in 2027 and delivery by 2030.

The river. According to the agglomeration’s land use plan (schéma d’aménagement), the St. Lawrence floodplain is delineated, based on federal-provincial mapping from 1979; the floodplains of the other watercourses are not yet, apart from portions of two rivers. For a waterfront address, see buying in a flood zone in Quebec.

Longueuil’s three sectors, one by one

This series devotes an analysis to each of the three boroughs.

Vieux-Longueuil. The city’s largest market, and the leading plex market on the South Shore over four quarters. It contains the cited heritage site of Vieux-Longueuil, more than 950 buildings protected under the Loi sur le patrimoine culturel (Quebec’s Cultural Heritage Act): exterior work there is regulated, something a buyer checks before signing a promise to purchase.

Saint-Hubert. The sharpest drop in sales, but the houses that sell fastest. The former Saint-Hubert airport, now the Aéroport métropolitain de Montréal, has been welcoming passengers in its new terminal since June 15, 2026, with Porter Airlines and Pascan Aviation. No source measures an effect on prices: near the airport, visit at flight times.

Greenfield Park. The smallest of the three: 41 sales, supply that doubles and no published quarterly median. The City’s 2026 budget plans an underground retention basin there, in the Murray sector, which it describes as “particularly vulnerable to heavy rainfall.”

Reading these figures without getting them wrong

The territory changes the figure. Centris names its pages after the City’s three boroughs; whether their boundaries match exactly has not been verified here. The APCIQ divides the territory differently: its “Vieux-Longueuil” sector combines Greenfield Park and Vieux-Longueuil, with 325 sales and a single-family median of $605,000 (-3%), where the Centris page for Vieux-Longueuil alone gives $625,000 (0%). The tables in this article do not mix the two sources.

A median follows the mix of sales. A change in the median price is not the change in value of any given house, since the properties sold differ from one summer to the next. Caution when sales are few, the APCIQ warns: the median of Saint-Lambert’s 31 condos rises 21%. For a specific address, the method is in auditing the comparables of a nearby sale.

What is missing is not estimated. The two Centris asterisks signal an “Insufficient number of transactions to produce a reliable statistic.” None of these gaps is filled in here; the four-quarter total takes over when it exists.

What it changes for you. A condo seller in Saint-Hubert faces 137 active units for 60 sales in the quarter: the competition shows in the supply, not in the median. A single-family buyer in Saint-Hubert, where the average selling time is 29 days, is well advised to have a pre-approval and an inspector lined up before visiting.

Frequently asked questions

Which Longueuil borough has the lowest prices? Among the single-family medians published for the third quarter of 2026, it is Saint-Hubert: $587,500, compared with $625,000 in Vieux-Longueuil. Over four quarters, Greenfield Park is the lowest, at $570,062. For condos, Saint-Hubert ($395,000) and Vieux-Longueuil ($398,500) are almost tied.

Are prices falling in Longueuil? Not according to Centris medians: 0% over one year for single-family homes in Vieux-Longueuil and in Saint-Hubert, +4% and +3% over four quarters. It is sales that are falling. These measures describe the past and do not say what prices will do.

Does the Longueuil market favour sellers? For single-family homes, yes, according to the APCIQ barometer for the third quarter of 2026: every price range in its two Longueuil sectors is under 8 months of inventory. For condos, the APCIQ places the South Shore on the sellers’ side, even though supply there is growing.
