Longueuil is the gateway to the South Shore, and one of the few off-island cities where the metro connects directly to downtown Montreal.
Three boroughs, three markets
Vieux-Longueuil holds most of the plex market and the older housing stock. Streets within walking distance of the Longueuil-Université-de-Sherbrooke station give access to the Montreal metro without a car.
Saint-Hubert is the largest of the three boroughs, and first of all a single-family market: 129 of its 216 sales in the third quarter of 2026, according to Centris (the Longueuil real estate market by borough).
Greenfield Park keeps its own identity, inherited from its status as a separate municipality until the mergers, with housing stock from the 1950s through the 1970s. Mature lots and established trees are a real argument for part of the buyer pool. Over four quarters, it is the most affordable of the three, at a median single-family price of $570,062, according to Centris.
The figures behind these three markets are in the Longueuil real estate market by borough in the third quarter of 2026: sales, median prices and days on market for Vieux-Longueuil, Saint-Hubert and Greenfield Park, as published by Centris.
What to check first here
System age, in Vieux-Longueuil and Greenfield Park. A good share of the stock is over fifty years old: roof, electrical service, cast-iron plumbing, French drain. That is not an obstacle, it is an amount to build into the offer.
Existing leases, for any plex. A building with below-market rents cannot be freely corrected: Quebec’s rent-setting regime tightly frames increases, and the real return has to be calculated accordingly.
Aircraft noise in Saint-Hubert, for properties in the approach corridors. It does not prevent a purchase, but it is negotiable.
Selling in Longueuil
Your buyer may come from the island as well as from the South Shore. A buyer leaving Hochelaga compares your property to what they would have gotten by staying on the island: the list price has to hold up against that comparison.
The comparative analysis is prepared at no charge, with recent sales from your specific borough and properties withdrawn without finding a buyer.
