Understand Senneville before you commit to an address
Senneville is a village of just over a thousand people at the north-western tip of the island, and the only one of these twenty-eight municipalities that is legally a village rather than a ville. It is mostly woodland, shoreline and estate lots (a handful of the properties here are measured in hectares) with a median detached house assessed at $1.07 million and almost no commercial activity at all. 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 Montréal 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 Senneville, 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 Senneville
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 Senneville actually involves
For a municipality of a thousand people the rate of 0.4941% is surprisingly moderate, and the explanation is the same as Baie-D'Urfé's next door: an industrial strip along Highway 40 and the Anse-à-l'Orme sector carry a share of the base. The bill on the median detached house is about $5,300. What a village this size cannot do is deliver services at scale, so almost everything beyond road maintenance and planning comes from the agglomeration or from a neighbouring municipality by agreement.
Senneville has spent decades protecting its character against development pressure, and a large part of its territory is now in the Anse-à-l'Orme nature park and the Grand parc de l'Ouest. That is why it looks the way it does and why there is very little to buy. Practically: no transit, no shops, no school in the village, large lots with the maintenance that implies, and a long drive to everything, which is more or less the point.
The village has almost no services of its own and buys most of what it needs, which is the only way a municipality of a thousand people can work. Everyday shopping, schooling and medical services are in the neighbouring towns, and the drive to them is part of daily life here.
Much of the territory is protected woodland and agricultural land, and the residential lots are the largest on the island. Those come with private wells or long service runs in places, extensive tree cover to maintain, and a set of bylaws designed specifically to stop the village becoming a subdivision.
Moving to Senneville: check these before you commit
- Servicing on the specific lot, since parts of the village are not on municipal sewer and well water is common.
- Protected and park land adjoining the property, which constrains what can be built and is why the setting is what it is.
- The genuine cost of maintaining a very large lot, which no calculator on this site models.
- How the property is serviced for water and sewer, which is not uniform in the village.
- What the bylaws permit on a large wooded lot, since the rules here are designed to restrict change.
The 339 detached one-dwelling houses on Senneville's 2026 roll are what the median above describes. The roll was built against market conditions on 1 July 2024 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 Senneville 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.
