In September 2026, Montreal’s South Shore records 746 residential sales and 4,050 properties available on Centris. Buyers have more choice than a year earlier, particularly among condos. Houses, condominiums and plexes nevertheless show different results.
Key takeaways
- 746 September sales : down 7% from September 2025.
- 4,050 active listings : up 32%; condo supply grows 43%.
- Figures cover the South Shore area in APCIQ’s bulletin, not Brossard or Longueuil individually.
The area and period covered
This report uses page 8 of APCIQ’s September 2026 monthly bulletin. All monthly changes compare September 2026 with September 2025. Saint-Jean-sur-Richelieu has a separate table on page 10. The figures come from the Centris system.
The results describe the Montreal South Shore statistical area. Valuing a property in Brossard, Saint-Lambert or Chambly still requires local comparable sales. The second-quarter local barometer remains a separate reference, covering a different period and a more specific area.
September residential activity
Lower sales accompany increases in new listings and available supply. Sales volume reaches approximately $487.7 million, down 5%. These indicators suggest more competition among sellers without establishing identical market conditions for every segment.

Houses, condos and plexes: prices and selling times
Houses account for 452 sales (−7%). Their median price is $640,300 (−1%), with an average selling time of 37 days. Condo sales decline 14%, supply grows 43% and the median price falls 3%. A 57-day selling time, compared with 41 in September 2025, makes the adjustment particularly visible.
Plexes move in a different direction: 63 sales, up 26%, with a median price of $775,000 (+2%). Their average selling time nevertheless reaches 61 days, 22 more than a year earlier. The smaller number of transactions calls for care: the mix of buildings sold can shift both medians and selling times.

Nine months in perspective
From January through September 2026, the South Shore records 8,096 sales (−4%). Year-to-date medians are $645,000 for houses (+3%), $405,000 for condos (+2%) and $811,500 for plexes (+7%). September and the year-to-date picture therefore tell somewhat different stories.
The market page chart compares matching months of 2026 and 2025. Earlier bulletin values are retained as published; Centris revisions can cause differences from the latest year-to-date total. A median describes recorded sales without directly measuring the value of the same property.
Adapt your strategy to your segment
For sellers, growing choice makes price positioning and a well-prepared file more important. For buyers, it allows more comparison but does not guarantee a discount on every property. Average selling time describes properties sold during the period; it does not predict the time required for an individual listing.
