Understand Longueuil before you commit to an address
Longueuil is two hundred and sixty-nine thousand people directly across the river from Montreal, and the centre of its own agglomeration. The city that merged in 2002, saw four of its suburbs demerge in 2006, and kept the core. Its metro station is a single stop from Berri-UQAM, which makes parts of this city a shorter commute to downtown Montreal than parts of Montreal. Figures come from the province's assessment roll and municipal budget file, measured the same way in all 28 municipalities here. It sits in the Longueuil agglomeration, so part of what an owner pays here funds services set by a council this municipality does not control.
The cost of living in Longueuil, and what a home costs
Two calculators on Quebec's own rules: semi-annual compounding and the real minimum down payment tiers, and the closing costs this province actually charges.
Rent or buy in Longueuil
Whether buying here beats renting, and the year it turns over. Both households start with the same cash, so the comparison is not rigged either way.
Mortgage calculator
Semi-annual compounding, the CMHC premium under twenty percent down, and the 9% Quebec sales tax charged on it in cash at closing, the highest in the country.
Then work out whether Longueuil is the right part of the region

What buying in Longueuil actually involves
Longueuil charges 0.7412%, the second-highest rate of the South Shore municipalities here after Saint-Lambert and the sixth-highest of these twenty-eight, on a median detached house assessed at $514,700: a bill of about $3,800. The structure is the mirror image of the island enclaves: Longueuil is the agglomeration's central city, so it carries the costs of being one, while Boucherville, Brossard, Saint-Lambert and Saint-Bruno pay a quote-part and set their own lower rates. Whether that is fair is a live local argument; that it is the case is not.
The Vieux-Longueuil core around the metro is dense, walkable and among the best-value urban housing anywhere in this region, and the further parts of the city (Saint-Hubert and Greenfield Park, both merged in 2002) are suburban in a completely different way. The median above averages all three. Saint-Hubert also has an exo station and an airport, and the difference between a Vieux-Longueuil condominium and a Saint-Hubert bungalow is larger than the difference between two municipalities elsewhere on this list.
Much of the housing is post-war duplex and triplex, which in this region is as much an investment decision as a housing one. Rental income, tenant rights under Quebec law and the rules on repossessing a unit for personal use are all part of that purchase, and they are not the same as elsewhere in Canada.
Moving to Longueuil: check these before you commit
- Which Longueuil: Vieux-Longueuil, Saint-Hubert and Greenfield Park are three different markets under one council.
- The real walk to the metro, because the station's catchment is smaller than the city by a very long way.
- The city's tax increase history rather than the current rate, since the agglomeration share is set separately from the local one.
- For any duplex or triplex, the leases, the rents and what Quebec law permits after a purchase.
The 33,267 detached one-dwelling houses on Longueuil's 2026 roll are what the median above describes. The roll was built against market conditions on 1 July 2023 and is fixed for three years, so it is a market value rather than a current one.
Sourced, dated, and separated from the guesswork
Every Longueuil figure below is cited, stamped with the period it describes, and editable, because a number for the whole city rarely describes your purchase. Appreciation and investment returns are assumptions rather than facts, and they are labelled that way. Read the methodology for how the line is drawn.
- Prices, rents and tax rates: published statistics and the official schedules.
- Nothing here is a lender quote, a pre-approval or financial advice.
