How many properties sold in Montreal from September 10 to 16, 2026?

In total, 261 closed sales were concluded in seven days, across all residential categories. The table below gives the full picture, with the year-over-year comparison:

Data from Centris, week of September 10 to 16, 2026, compiled by Endurance Groupe Immobilier par Tardif. Sales-to-new-listings ratio: above 60%, seller’s market; below 40%, buyer’s market.

Which area performed best this week?

Ville-Marie once again leads the condo segment with 18 sales, despite the category’s 18.1% year-over-year decline. Rivière-des-Prairies/Pointe-aux-Trembles dominates single-family homes with 10 sales, reflecting sustained demand in the island’s more affordable eastern areas. In four-plexes, Ahuntsic accounts for 4 of the week’s 10 transactions — a sign that multi-unit investors continue to target this neighbourhood. For buildings of 5 or more units, the average GRM sits at 16.90 and the average price per door at $223,038.

What’s the read from the ground this week?

“What strikes me this week isn’t just the ratio — it’s the split. The duplex segment is down 45.9%. That’s the worst number we’ve seen in that category since we started these bulletins. And at the same time, four-plexes and 5+ unit buildings are up. Both of these realities coexist in the same market, the same week, in Montreal. What that tells me is that multi-unit buyers have done their math. Rates moved at the right time for them, sellers finally adjusted, and the numbers are starting to come in. For the duplex, it’s different — the typical buyer is less rushed, often less capitalized, and they’re waiting. It shows in the data. The triplex on Saint-Dominique Street selling at 112.6% in 27 days wasn’t a coincidence: it was the right asset, at the right price, in the right area. That still sparks competition.”

Why is the duplex segment dropping while multi-unit buildings climb?

Twenty duplexes sold, versus 37 last year — a 45.9% decline that marks the segment’s steepest year-over-year drop since we began these bulletins. With 61 new listings and only 7 expirations, inventory remains limited, but demand has clearly contracted in this segment. By contrast, four-plexes are up 25.0% (10 sales versus 8) and buildings of 5 or more units are up 50.0% (9 sales versus 6). For these properties, the average GRM sits at 16.90 and the average price per door at $223,038, suggesting institutional and semi-institutional investors see an entry window in the current market.

This week’s notable transaction captures the nuance perfectly: the triplex at 7811-7815 Saint-Dominique Street (Villeray/Saint-Michel/Parc-Extension) sold for $1,350,000 against an asking price of $1,199,000, or 112.6% of list, in 27 days. In a market that’s broadly favorable to buyers, a well-located, well-presented triplex can still spark a bidding war.

What does the Tardif Index say?

The reference monthly score remains July 2026’s: 24.5/100, “light buyer” zone. The Tardif Index indeed combines three components — the sales-to-new-listings ratio (40%), the expiration ratio (30%), and annual sales momentum (30%) — into a score out of 100, published monthly. The weekly bulletin, for its part, has no score of its own: it documents the week and feeds into next month’s score.

The data for September 10 to 16 confirms July’s score’s buyer-leaning direction: an overall sales-to-new-listings ratio of 32.9%, still well below the 40% threshold, and expirations up 25.7% year-over-year. Multi-unit buildings, however, are sending a contrary signal worth watching in the coming weeks — one that could weigh positively on the August 2026 score, expected this month.

Notable transactions of the week

The Saint-Dominique Street triplex, sold at 112.6% of asking in 27 days, captures the full contradiction of the week: in a market broadly favorable to buyers, a strong multiplex asset that’s well presented can still spark a bidding war. By contrast, the Westmount condo sold at only 78.9% of list after 218 days illustrates the fate of properties whose price hasn’t kept pace with the market’s adjustment.
