The municipalities around Montreal

Two towns on the island of Montreal, 9 kilometres apart, share a police force and a fire service — and one of them charges its homeowners more than twice what the other does. That is not a story about competence or service levels, and it is the pattern that runs through this whole region. These are 28 municipalities around Montreal, each with its own hub and its own two calculators, all measured from the same two provincial files.

Side by side

All 28, sorted by distance from downtown

The house value is the median detached one-dwelling residence on the 2026 assessment roll, computed the same way in every municipality from the province's own open data. The rate is what each council adopted for 2026, in the unit Quebec publishes it in — dollars per $100 of assessment. The bill column is the two multiplied together, and it is the number an owner actually receives.

The roll market date column is not decoration. A Quebec assessment roll runs three years and is built against market conditions eighteen months before it takes effect, and these municipalities are on different cycles: 12 of them describe the market on 1 July 2023 and 16 describe 1 July 2024. The bill is exact either way, because the rate is charged against the roll — but comparing one municipality's value with another's across that line compares two different markets, and this region moved between them. Rent is deliberately not a column here. CMHC surveys the Montreal area by zone rather than by municipality, so a rent column would be the same regional figure twenty-eight times; it appears on each municipality's calculator page, labelled, instead.

The thing that actually drives the table

The rate is a map of where the commerce is

A municipal budget is divided across whatever assessment a municipality has. Put an airport, a refinery or an industrial park inside the boundary and the houses are taxed lightly; draw the boundary around nothing but houses and they are not. Two pairs on this table make the point better than any argument:

Dorval and Beaconsfield are 9 kilometres apart on the same island, in the same agglomeration, policed by the same force and covered by the same fire service. Dorval contains Montréal–Trudeau airport and charges 0.3964 per $100; Beaconsfield has no commercial development at all and charges 0.8096. On their respective median houses that is $2,574 a year against $7,753.

Boucherville and Saint-Lambert are the south shore version. Both left Longueuil in 2006, both pay the same agglomeration council. Boucherville has one of the largest industrial parks in Quebec and charges 0.3976; Saint-Lambert is an old residential suburb with almost no commerce and charges 0.7507$2,602 a year against $8,109 on a house worth two-thirds more.

Across the whole table the rate runs from Mirabel at 0.3270 to Montréal-Ouest at 0.9538 — a factor of 2.9 — and the bill from $1,843 in Mirabel to $23,918 in Westmount, a factor of 13. The house values run from $386,800 in Montréal-Est to $3,633,250 in Westmount. And Montreal itself, the city all of these are suburbs of, charges 0.4631 — below the median of its own suburbs, which is not what anyone expects.

Why there are twenty-eight of them at all

The mergers of 2002 and the demergers of 2006

In 2002 the Quebec government merged every municipality on the island of Montreal into one city, and did the same on the south shore around Longueuil. In 2004 the affected towns held referendums, and on 1 January 2006 18 of the municipalities on this list were reconstituted — fifteen on the island, four around Longueuil. They got their councils, their names and their local services back.

What they did not get back was independence. Police, fire, water production, arterial roads, public transit and social housing are agglomeration competences, delivered centrally and funded by a levy an agglomeration council sets. A reconstituted municipality pays that levy, holds a small share of the votes on the council that sets it, and funds it from its own tax base. Roughly half of what an owner in one of these municipalities pays is for services their council does not control.

That structure explains the shape of the table but not its direction, and it is worth being precise about which. Demerging did not make a municipality expensive: Boucherville and Dorval both demerged and both have among the lowest rates here. What demerging did was remove the pooling — so a municipality's rate now depends on its own assessment base rather than on the island's. For a town with an airport that was a good trade. For a town with nothing but houses it was not, and Montréal-Ouest at 0.9538 per $100 is what the bad end of it looks like.

The entry cost, and the one this site cannot fully model

The welcome tax is set by the municipality, not the province

Every other transfer tax on this site is provincial or state-level, with Toronto the single exception. Quebec inverts that. The province sets a floor — 0.5% to $62,900, 1.0% to $315,000, 1.5% above — and then lets every municipality raise the rate on any bracket above $500,000 to as much as 3%. Montreal alone is authorised to go further, and does, to 4% above $3,113,000.

On a $1,000,000 purchase the provincial floor is $13,111. Montreal's own table charges $15,349 on the same purchase — $2,239 more, on a difference of nothing but which side of a municipal boundary the house is on. Many municipalities in this region have adopted tables of their own between those two figures.

So this is the limit of what these pages can tell you. The transfer duty modelled here is the provincial floor: 0.5%, 1.0% and 1.5%. Quebec lets every municipality raise the rate on any bracket above $500,000 to as much as 3%, and many in this region have. Check the municipality's own by-law before treating the closing cost here as yours — on a purchase over $500,000 it is a floor rather than an estimate. The other Quebec peculiarity worth knowing before you budget: the duty is not collected at closing. The municipality bills it some months later, once the transfer is published and the roll updated, by which time a great many buyers have spent the money.

By part of the region

Six groupings, and none of them official

The CMM publishes five sectors and they cut across what people here actually say, so the grouping below is editorial — built from the names in use. What is not editorial is the pattern inside it: the enclaves carry the region's highest bills, the West Island splits almost perfectly by whether a municipality has commerce in it, and the Rive-Nord is where the cheap end of the table lives.

The enclaves

Westmount The most expensive housing in Quebec, and the largest tax bill in this region by a factor of two. · Mont-Royal A 1912 garden city with radial streets, an REM station in the middle of it, and a rate well below its neighbours. · Hampstead A 1914 garden suburb of seven thousand people, and one of the highest tax bills in the region. · Montréal-Ouest The highest residential tax rate in this region, on a railway village of five thousand people. · Côte-Saint-Luc The largest of the enclaves, half of it apartments, and a rate that reflects having almost no commerce.

The West Island

Dorval The airport pays the tax bill: the lowest residential rate on the island of Montreal. · Dollard-des-Ormeaux The largest West Island suburb, built almost entirely between 1960 and 1985, and no station in it. · Pointe-Claire A lakeshore village, a regional shopping centre and an REM terminus in the same municipality. · Kirkland Large lots, a pharmaceutical corridor and an REM station of its own. · Beaconsfield Almost purely residential, and it pays for that with the second-highest rate on the island. · Baie-D'Urfé Expensive houses and a cheap rate, because an industrial park sits behind them. · Senneville A thousand people on the largest lots on the island, and the only village among them. · Sainte-Anne-de-Bellevue The far tip of the island: a boardwalk, two university campuses and the REM's western terminus.

The east end of the island

Montréal-Est The cheapest houses in this region, on the island, next to the refineries.

The South Shore

Saint-Lambert The oldest and most expensive of the South Shore suburbs, four kilometres from downtown. · Longueuil The fifth-largest city in Quebec, one metro stop from downtown, with the South Shore's highest rate. · Brossard The REM's southern terminus, and the fastest-changing municipality in this region. · Boucherville The lowest residential rate on the South Shore, funded by one of the region's largest industrial parks. · Saint-Bruno-de-Montarville A mountain, a national park and a commuter station, at a mid-table rate. · Châteauguay South-west of the island, on the far side of the bridge everyone warns you about.

Laval and the Rive-Nord

Laval The third-largest city in Quebec, a whole island of its own, and three metro stations. · Terrebonne The largest city on the Rive-Nord, with an eighteenth-century core and a rate to match its growth. · Saint-Eustache A low rate, low assessments and the REM one municipality away. · Mascouche The Rive-Nord's low-rate outlier, and the terminus of the region's newest rail line. · Repentigny The eastern gateway on the north shore, and the debt line is visible in the rate. · Blainville The most expensive houses on the Rive-Nord, at one of its lower rates. · Mirabel The lowest tax bill in this region, on the largest territory and the site of Canada's most famous expropriation.

Vaudreuil-Soulanges

Vaudreuil-Dorion The western gateway, growing faster than anywhere else in this region.

Two members of the Montreal agglomeration are not on this list. Montreal itself is the reference row rather than one of the twenty-eight. And L'Île-Dorval — a legally constituted city of nine people on an island off Dorval, reachable by municipal ferry — has seventy-four units on the 2026 roll, not one of them a detached single-dwelling residence, and adopted no residential tax rate at all. There is nothing here for these pages to measure, and saying so is better than inventing it.

Where these figures come from

Sources

Every number above comes from the Quebec government's own open data — the 2026 assessment roll and the 2026 municipal budget forecasts, one file per municipality, published by the Ministère des Affaires municipales et de l'Habitation. The medians were computed from the roll directly rather than taken from anyone's summary. Rents are CMHC's for the Montreal CMA as a whole ($1,200 average across the purpose-built stock, $2,050 asking, 2.9% vacancy) and are not broken out by municipality anywhere on this site.

Nothing here is a listing, a lender quote or financial advice. Assessment rolls are refiled every three years and councils set rates every winter.
