Senneville doesn’t advertise itself. With fewer than 1,000 residents and a density of just 128 per km² — the lowest of any municipality on the Island of Montréal by a considerable margin — it is less a neighbourhood than a sanctuary. Large forested lots, meandering roads with almost no through traffic, and a position at the island’s northwestern tip combine to create something genuinely rare in a major metropolitan area: true privacy, within city limits.
The housing profile is about as concentrated as it gets. At 91% single-family homes and essentially no multi-unit inventory, Senneville is a market of detached properties on substantial lots — many of them heavily treed, some with water frontage along the Ottawa River or Lac des Deux Montagnes. Transactions here are infrequent by design, not by lack of demand. When properties come to market, they tend to draw from a narrow, well-defined buyer pool that knows exactly what it’s looking for and is financially positioned to act. With 49% of households earning over $150,000 annually — among the highest concentrations on the entire island — this is unambiguously an executive and generational wealth market.
The ownership rate of 55% alongside a 45% renter cohort is worth noting, and somewhat counterintuitive given the income profile and housing type. The likely explanation lies in Senneville’s adjacency to McGill’s Macdonald Campus and the agricultural research facilities nearby, which bring a small but meaningful population of faculty, researchers, and institutional residents who rent rather than own. That dynamic doesn’t diminish the ownership market — it exists in parallel with it, largely invisible to the executive buyer segment.
What defines Senneville as a real estate proposition is scarcity in its most absolute form. There is no new development coming. There is no land to subdivide. The municipality’s semi-rural character is protected by its own geography and the deliberate absence of the infrastructure that drives densification elsewhere. Buyers who secure a position here are acquiring something that simply cannot be replicated — a private, forested estate-scale property at the edge of the island, with all of Montréal still within reach.
For a certain kind of buyer, there is nowhere else quite like it.

Thinking of Buying or Selling in Senneville?
Senneville is one of the most transaction-light markets on the Island — which means when a property does come available, both buyers and sellers are operating with very limited comparable data. Getting the positioning right requires deep familiarity with a market that rarely shows its hand.
