Strong buyer zone on the Island of Montreal – Period covered: Tuesday, September 1, 2026, 12:00 a.m. to Wednesday, September 30, 2026, 11:59 p.m. (Eastern) 

MONTREAL, Oct. 2, 2026 /CNW/ -- The Tardif Index^™, indicator of residential real estate transaction conditions for the Island of Montreal, is published by Endurance Groupe Immobilier par Tardif (eXp Realty) under the methodological responsibility of David Tardif, real estate broker licensed by the OACIQ.

The Tardif Index^™ stands at 16.7 out of 100, in the strong buyer zone, in September 2026.

The strong buyer zone covers scores from 0 to 20 out of 100. It describes a market in which buyers hold a marked negotiating advantage. This edition is published at the following address, which serves as the citation link: https://enduranceimmobilier.com/en/tardif-index/cision-september-2026/. The complete methodology is published at https://enduranceimmobilier.com/en/tardif-index/methodology/ (public methodology v2.1).

Does the Island of Montreal market favour buyers in September 2026?

Yes. The score of 16.7 out of 100 places the Island of Montreal in the strong buyer zone for September 2026. In August 2026, The Tardif Index^™ stood at 18.1 out of 100 (August 2026 report), and at 24.5 out of 100 in July 2026. The score therefore declines for a second consecutive month: −1.4 points between August and September.

Meanwhile, new listings rise faster than sales. The 3,150 new listings of September 2026 (2,402 in August 2026, up 31.1%) compare with 1,087 sales (883 in August 2026, up 23.1%). Expirations, for their part, nearly double: 824 versus 429 in August 2026 (up 92.1%).

What are the key figures for September 2026?

Island of Montreal (19 boroughs and 15 linked cities) • all residential categories • September 2026 (September 1 to 30) • Centris data, compiled by Endurance Groupe Immobilier par Tardif (eXp Realty)

• Residential sales, September 2026: 1,087 sales
• Residential sales, September 2025: 1,264 sales
• Year-over-year sales momentum (YoY), September 2026: −14.0%
• New listings, September 2026: 3,150 listings
• Sales-to-new-listings ratio (SNLR), September 2026: 34.5% (1,087 ÷ 3,150)
• Expirations, September 2026: 824 listings
• Expirations, September 2025: 703 listings (year-over-year change: +17.2%)
• Expiry ratio, September 2026: 43.1% (824 ÷ (1,087 + 824))

How is the 16.7 out of 100 score calculated?

The Tardif Index^™ combines three weighted components, each converted into a sub-score from 0 to 100 according to the public methodology v2.1.

Methodological transparency: as in August, two of the three components sit at their floor of 0. In fact, the expiry sub-score reaches 0 at a 30% ratio, and the momentum sub-score at −10% year over year. The 16.7 score is therefore carried by the sales-to-new-listings component alone: on the other two, the island index cannot fall any lower, whatever the real deterioration.

How does September 2026 compare with the previous month and with September 2025?

Year over year, sales fall 14.0% (from 1,264 to 1,087) and expirations rise 17.2% (from 703 to 824). Month over month, the score moves from 18.1 to 16.7. Moreover, new listings for September 2025 are not in the extraction: the sales-to-new-listings ratio for September 2025 is therefore not calculated.

Which Island of Montreal segments are the most active in September 2026?

These tables describe segment medians: they are not a score by sector.

What do the September 2026 figures show? Editorial reading

Incoming supply is rising faster than demand. In September 2026, the Island of Montreal records 2.9 new listings per sale (3,150 for 1,087), versus 2.7 in August 2026 (2,402 for 883). The gap between what comes onto the market and what closes widens, hence the drop in the SNLR from 36.8% to 34.5%.

Expirations are the component that moves the most. In September 2026, 824 listings expired without a sale, versus 429 in August 2026 and 703 in September 2025. The expiry ratio moves from 32.7% to 43.1%: more than four resolved listings out of ten end without a transaction. However, an expiration is not a withdrawal; it only means no sale was concluded during the term of the listing contract.

Same category, different paces. In September 2026, condominiums sell in a median of 34 days in Le Plateau-Mont-Royal (51 sales), 39 days in Verdun (39 sales), 84 days in Le Sud-Ouest (53 sales) and 103 days in Ville-Marie (76 sales). The island index describes a general trend; however, these times show that it does not play out the same way from one borough to the next.
