Understand Saint-Lambert before you commit to an address
Saint-Lambert is a small, old, leafy municipality at the south end of the Victoria Bridge, closer to downtown Montreal than most of the island is. Four and a half kilometres in a straight line. Its median detached house is assessed at $1.08 million, the highest on the South Shore, and it charges 0.7507%, the fifth-highest rate of these twenty-eight municipalities and the highest on the South Shore. 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 Saint-Lambert, 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 Saint-Lambert
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.

What buying in Saint-Lambert actually involves
Saint-Lambert demerged from Longueuil in 2006 and, unlike Brossard and Boucherville, has almost no commercial or industrial assessment to fund itself with, so it landed in the same position as the island's residential enclaves. About $8,100 a year on the median detached house, on a small municipality with a village-scale main street and no big-box anything. The proximity, the housing stock and the schools are what people pay for; the rate is what it costs.
The practical draw is that this is a genuinely walkable old suburb with a commuter station, and the Victoria Bridge and the Champlain are both close, which is also the risk, because both of them are the commute and neither has spare capacity. Saint-Lambert also sits alongside the Seaway, and the recreational path along it is one of the better pieces of public realm in the region.
The town is walkable in a way very little of the South Shore is: a small commercial street, a station in the middle, and a street grid of older houses around both. That is what the price premium buys, and it is concentrated in the streets close to the centre rather than spread across the town.
The housing is older than its neighbours', including a substantial number of pre-war houses, and the town regulates alterations in its older sectors. Century-house questions apply here, and so does the process for changing anything visible from the street.
Moving to Saint-Lambert: check these before you commit
- The bill rather than the rate, since on a house at this assessment Saint-Lambert is one of the more expensive municipalities in Quebec to own in.
- Which bridge your commute depends on, and what it looks like at your hour.
- The age and condition of the housing stock, much of which predates the war.
- The town's rules on exterior alterations in the older sectors, which are enforced.
- How far the address really is from the station and the commercial street, since the premium tapers quickly.
The 3,044 detached one-dwelling houses on Saint-Lambert'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 Saint-Lambert 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.
