Mississauga’s housing market in September 2025 reflected a decisive shift toward buyer-friendly conditions as inventory reached its highest level in more than fifteen years and prices trended downward across all major housing categories. Sales volumes have begun to stabilize after a period of disruption driven by rate hikes and broader economic uncertainty, but the supply of available homes continues to outpace demand, placing downward pressure on pricing. Source: Cornerstone Association of RealtorsⓇPricingHome prices in Mississauga declined on a year-over-year basis in September, with every property type showing reductions. The MLS® Home Price Index composite benchmark price fell to $972,100, representing an 8.9% decrease compared to September 2024. Single-family homes saw a benchmark price of $1,234,900, down 9.4% from last year, while townhouse and row units recorded a benchmark of $769,000, reflecting a 7.3% annual decline. The most significant price adjustment occurred in the apartment segment, where the benchmark price decreased by 11.5% to $570,300.

When examined over a longer timeframe, the year-to-date average price came in at $1,004,272, down 5.8% from the same period in 2024. The consistency of these reductions across both monthly and year-to-date figures suggests a sustained recalibration after earlier market peaks. SalesSales activity in September offered a sign of gradual recovery. An increase of 10.4% in sales was seen compared to September 2024. Despite this gain, overall transactional volume remains subdued relative to longer-term norms. Sales remained 6.3% below the five-year average and 26.4% below the ten-year average for the month. On a year-to-date basis, sales totalled 4,136 units, which represents a 10.7% decline from the first nine months of 2024. Inventory and SupplyNew listings surged in September, with a 13% increase year over year and the highest count for September in five years. Active listings rose to 2,727 units, up 24% from September 2024. Active listings now sit 57.3% above the five-year average and 71% above the ten-year average. Buyers now have a broader range of options.Market BalanceThe months of inventory figure reached 5.5 in September, well above both the 4.9 levels observed last year and the long-run average of approximately 2.8 for this time of year. The Sales-to-New-Listings Ratio stood at 36.8, reinforcing that supply is outpacing demand. Markets with ratios below 40% are typically characterized as favourable to buyers. With more listings arriving and sales recovering only slowly, these conditions may persist. For active buyers, this environment offers negotiation leverage, options across price brackets, and fewer bidding pressures.
