Saint-Hubert is the largest of Longueuil’s three boroughs: 66 km² according to the Ville de Longueuil, the territory of the former city of Saint-Hubert. It is also the only one that combines an airport, a permanent agricultural zone and a commuter rail station.
What moves prices here
The age of the housing stock. The Ville de Longueuil archives recall that Saint-Hubert and the cité de Laflèche merged on 30 October 1971, and that the new city went from 37,000 residents in 1971 to more than 82,000 within thirty years. That growth left entire neighbourhoods of bungalows, split-levels and cottages, uniform within a sector and very different from one sector to the next. The year of construction weighs more here than the postal code.
Access. Autoroute 30 crosses the borough, Route 112 runs through it as boulevard Cousineau and Route 116 as boulevard Sir-Wilfrid-Laurier. Gare Longueuil-Saint-Hubert, at 2505 rue Patrick, is served by exo line 13 Mont-Saint-Hilaire, with a 600-space park and ride according to exo. The RTL runs lines 8 and 88, and its on-demand service links several sectors to Terminus Longueuil and the REM’s Panama station.
The airport. Montreal Metropolitan Airport inaugurated its passenger terminal on 15 June 2026. For a buyer the question is not the terminal: it is where the address sits relative to the approach corridors.
The southern boundary. Part of the borough is in the permanent agricultural zone: the stock of buildable land there is closed and growth happens by redevelopment of the arteries.
The sectors
Vieux-Saint-Hubert, along chemin de Chambly, is the old core and the sector where densification is most visible: multi-storey buildings are replacing former commercial lots. This is readable in the zone’s specification grid published by the Ville de Longueuil.
Laflèche, against Greenfield Park, is the former city merged in 1971: smaller lots, postwar houses, and a stock where the age of the systems weighs heavily in the negotiation.
Parc-de-la-Cité is organized around the park of the same name, at 6201 boulevard Davis. The streets around it form a micro market of their own.
Croydon-Iberville and Boisé-Pilon cover the more recent developments: larger lots, garages, finished basements. This is where buyers priced out of Boucherville or Saint-Bruno-de-Montarville most often land.
Les Maraîchers, to the south, covers most of the agricultural zone: buying land there is not like buying it anywhere else.
Selling in Saint-Hubert
The useful number here is not a city average, it is the comparison between two streets. According to APCIQ, in August 2026 the South Shore of Montreal recorded 664 sales, down 15% over twelve months, with 3,703 active listings, up 28%. For single-family homes: a median price of $655,000, up 4%, and 37 days on market on average. For condominiums: $400,000, flat, and 51 days.
The assessment roll matters too. The Ville de Longueuil filed the agglomeration’s 2025-2026-2027 rolls on 30 September 2024; they reflect the market as of 1 July 2023 and have been in force since 1 January 2025. The average assessment of a single-family home reaches $656,400, against $473,200 on the previous roll. The City notes it then spread the effect over three years because the increase mainly hit the first-time buyer market of Greenfield Park and Saint-Hubert.
The comparative analysis is prepared at no charge, from the sales of your micro sector and the properties withdrawn without a buyer.
Buying in Saint-Hubert: what gets checked
Aircraft noise. In its urban planning data, the Ville de Longueuil publishes an Aéroport Courbes Isophoniques layer and a Contraintes sonores totales layer, consultable address by address. The airport publishes the WebTrak flight tracking tool and a complaint form, and Transport Canada confirmed the ban on commercial night flights, in force since 1 April 2024. The acoustic study the airport commissioned in 2023, which concludes the new terminal has a reduced impact, is contested by a citizens’ group. In practice: the City’s map for the exact address, then two visits at different hours.
Zoning, municipal and federal. The zone’s specification grid says what is allowed on the lot. The St-Hubert Airport Zoning Regulation, a federal regulation, further prohibits erecting a building, structure or object whose top would exceed the airport’s protective surfaces, and lets the Minister of Transport require the removal of vegetation that exceeds them.
The agricultural zone. Since 9 November 1978, the Act respecting the preservation of agricultural land and agricultural activities has prohibited, without authorization from the Commission de protection du territoire agricole du Québec, using a lot in the agricultural zone for a purpose other than agriculture, subdividing it or removing its arable soil. A large, inexpensive lot in the south is therefore not a building lot until the CPTAQ has ruled.
The building. On a stock largely built after 1960: aluminum wiring, common in houses from the mid 1960s to the late 1970s, which insurers often ask to have certified by a master electrician; the old fuel oil tank, whose eventual decontamination follows the property; and the original French drain. An up to date certificate of location and a pre-purchase inspection: specialized tests are billed separately, as the pre-purchase inspection guide explains.
You also benefit from the Intégri-T guarantee, paid by the seller or by the buyer, covering up to $50,000 in latent defects for three years after the notarial deed.
