Greenfield Park, Longueuil Real Estate Market: Q3 2026

Between July and September 2026, Centris counted 41 residential sales in Greenfield Park, the least populous of Longueuil’s three boroughs, 4% fewer than a year earlier. Over the same period, the number of properties for sale doubled: 73 active listings, up 102%. With so few transactions, Centris does not publish the quarterly median price of a single-family home. Over the last four quarters, it stands at $570,062, unchanged from a year earlier.

The Greenfield Park, Longueuil real estate market by the numbers

According to the Charter of Ville de Longueuil, the borough covers the territory of the former City of Greenfield Park and elects 1 of the city’s 18 councillors. Centris publishes it under the name “Longueuil (Greenfield Park)” and credits it with 17,197 residents in the 2021 census, compared with 146,388 in Vieux-Longueuil and 90,898 in Saint-Hubert.

Plexes of 2 to 5 units. Two sales in the quarter, 10 over four quarters: Centris publishes no price for Greenfield Park.

Few sales: what the figures can tell you

One quarter is not enough. Twenty-eight houses sold in three months is too few for Centris to publish a median price, a selling time or even the change in the number of sales. The only solid footing is the total for the last four quarters: 109 single-family homes sold (+3%), a median unchanged at $570,062 and 34 days on the market, with no change from a year earlier.

What the four-quarter total supports, and no more. Over one year, single-family sales are holding and their median is not moving. The condo median gains 12%, but on 50 sales: a median describes the properties that changed hands, not the value of any given home, and the mix of sales alone is enough to shift it. The APCIQ says as much: these statistics should be read “with caution, particularly when the number of transactions is low.”

The APCIQ grouping. Its barometer combines Greenfield Park and Vieux-Longueuil in its sector 43: 145 single-family sales in the third quarter, at a median price of $605,000 (-3%). In the same quarter, Centris counts 116 single-family homes sold in Vieux-Longueuil and 28 in Greenfield Park: sector 43 mainly describes Vieux-Longueuil. Over the 12 months ending in September, every single-family price range in the sector favours sellers, with 1.5 to 4.1 months of inventory; the APCIQ puts a balanced market between 8 and 10 months.

What changed in a year

Supply jumped, sales did not. Active listings rose to 73 (+102%), including 36 single-family homes (+63%) and 33 condos (+266%), while sales slipped 4%. On such a small base, a few dozen listings are enough to double a total, but the movement is regional: on the South Shore, Centris counts 26% more active listings, and 40% more for condos.

The regional context. According to the APCIQ’s October 14, 2026 release, the Montreal metropolitan area recorded 12% fewer sales and 17% more listed properties in the third quarter than a year earlier. Single-family sellers keep the upper hand in each of the major areas, and the South Shore remains in sellers’ favour for condos.

Greenfield Park’s language status: what it changes

A recognized borough, status kept in 2023. Section 12 of the Charter of Ville de Longueuil deems the borough recognized under section 29.1 of the Charter of the French Language. Since 2022, section 29.2 withdraws that recognition from a municipality that no longer has a majority of residents whose mother tongue is English, unless a resolution to keep it is adopted within 120 days. On December 12, 2022, the Office québécois de la langue française notified the borough that 27.4% of its residents have English as their mother tongue, according to the 2021 census. On January 9, 2023, the borough council voted unanimously to keep the status, and the borough still appears on the Office’s list of recognized bodies as of October 20, 2026.

What it changes. The borough may post signs in two languages, with French predominant (section 24), and may draw up its documents and offer its services in both languages (section 26), but it must make its services available in French (section 23). The status applies to the borough, not to the city: the Ville de Longueuil website is in French only.

What it does not change. No source consulted says this status affects a real estate transaction. The language of the promise to purchase or of the notarial deed is governed by other rules, explained in the article on language and your real estate transaction.

What is moving in Greenfield Park and Longueuil in 2026

Boulevard Taschereau: a bus line, not a tram. In June 2025, Longueuil and Brossard presented a preliminary design vision built around a rapid bus service. What is already running is metropolitan line 901 Taschereau of the Autorité régionale de transport métropolitain (ARTM), operated by the Réseau de transport de Longueuil and in service since August 24, 2026. According to the ARTM’s 2025-2029 implementation plan, it links the Longueuil terminus, on the metro’s yellow line, the Panama REM station and terminuses in La Prairie, Candiac and Delson.

The hospital. Among the hubs served by line 901, the ARTM lists Hôpital Charles-Le Moyne, with 515 beds, at 3120 boulevard Taschereau in Greenfield Park. No source consulted measures its effect, or the line’s, on prices in the neighbourhood.

Heavy rain: a basin in the Murray sector. The City’s 2026 budget lists Vieux-Longueuil and Greenfield Park among the boroughs “particularly affected by episodes of heavy rainfall” and announces an underground retention basin in the Murray sector, which it describes as “particularly vulnerable.” The risk being addressed is pressure on the sewer system during heavy rain, not a river flood: ask for the history of water damage and check the backwater valve, as detailed in the article on climate resilient renovations.

The former city hall. The same budget plans to redevelop it, keeping the borough office and adding an intergenerational community centre; the project starts in 2026 with plans and specifications, at $5 million.

Boulevard Churchill. Longueuil’s 21-35 urban plan (plan d’urbanisme) devotes a special planning program (programme particulier d’urbanisme) to this “community and commercial heart” of the borough. Among the challenges, it cites “sensitive residential densification” and notes, between Fairfield and Verchères streets, a group of buildings with a “Boomtown” influence that is “of interest for preservation and enhancement.” The City’s heritage management framework, dated 2018, subjects the entire borough to a PIIA (plan d’implantation et d’intégration architecturale, an architectural review process) for any change to exterior appearance. The regulations were revised in 2025: before exterior work, have the rule for your address confirmed at 450 463-7311.

Greenfield Park and its Longueuil neighbours

A lower median. Over four quarters, the single-family median in Greenfield Park, $570,062, is below those of Saint-Hubert ($588,750), Vieux-Longueuil ($616,500) and the South Shore ($642,125). In Brossard, at the other end of the Taschereau corridor, it reaches $725,000. These medians do not compare similar houses: size, age and lot vary from one territory to the next. The average selling time over four quarters, on the other hand, is similar: 34 days in Greenfield Park, 32 in Vieux-Longueuil, 31 in Saint-Hubert.

The assessment roll does not separate the boroughs. The 2025-2026-2027 roll reflects the market as of July 1, 2023. The City publishes average values for the city of Longueuil as a whole, $545,700 for a single-family home (+40%) and $365,500 for a condo (+41%), and none by borough.

The neighbouring sectors are profiled on the Longueuil, Vieux-Longueuil, Saint-Hubert and Brossard pages.

Selling or buying in Greenfield Park

For a seller. Twice as many active listings as a year ago: buyers are comparing. With 28 single-family sales in the quarter, no median sets your price; it is built from dated comparable sales in your micro-sector: see how to audit comparables. Before redoing the facade, check the PIIA, and keep the history of water damage on hand.

For a buyer. Choice has grown, but the APCIQ classifies single-family homes in sector 43 as favouring sellers. Budget for the welcome tax (transfer duties) using Longueuil’s brackets: 0.5% up to $62,900, 1% up to $315,000, 1.5% up to $630,100 and 3% above that. On a base of $570,062, the four-quarter median, the duty comes to $6,661.43. The base can exceed the price paid: the City uses the highest of the price, the consideration stated in the deed and the roll value multiplied by 1.06 in 2026. Below $630,100, these brackets are the ones set by provincial law, so the welcome tax calculator, with the “Other Quebec municipality” option, gives the right amount; above that, use the City’s calculator.

Frequently asked questions

Why does Centris show no median price for Greenfield Park this quarter? There are too few sales: in that case, Centris replaces the figure with **. Use the total for the last four quarters, $570,062 for a single-family home, and do not rebuild a quarterly median from other figures.

Do you need to speak English to deal with the borough? No. The borough may serve the public in English, but section 23 of the Charter of the French Language requires it to make its services available in French.

Can the borough lose its status? Section 29.2 provides for a review in light of each census. If the English mother tongue majority is still missing, the borough receives a notice and has 120 days to vote to keep its status, as it did in 2023.
