Newmarket sales dip as supply rises
Newmarket’s housing market lost some of the momentum it had built over the summer in September, as sales fell and new listings rose, according to local real estate data. The shift contrasted with nearby Aurora, which showed signs of renewed activity during the same month.
Across the Greater Toronto Area, the Toronto Regional Real Estate Board reported 5,040 homes changed hands in September, down 9 per cent from the same month last year. New listings in the GTA declined year over year, falling 14.4 per cent to 16,500, while the GTA average selling price dropped 5.1 per cent to $1,006,409. The MLS Home Price Index composite benchmark fell 4.7 per cent.
But month-to-month figures for Aurora and Newmarket showed a divergence, reflecting a fall market still searching for direction.
“September gave us the first real test of the fall market, and the biggest takeaway is that Aurora and Newmarket are starting to behave differently again,” said Matthew Gizzie, a local realtor with Keller Williams Realty Centres. “Aurora improved from a very weak August, while Newmarket gave back some of the strength it had built through the summer.”
Key local numbers
In Newmarket specifically, activity slowed in several measures in September:
- Sales fell from 80 in August to 67 in September — down about 16 per cent.
- New listings surged from 161 to 240.
- Active listings rose from 322 to 339.
- Months of inventory climbed from 4.08 to 5.06.
- Median days on market increased from 24 to 28.
Gizzie noted the 67 sales recorded in September were the second-lowest September total in available historical data going back to 2010, with only September 2023 recording fewer transactions.
| Measure | August | September |
|---|---|---|
| Sales | 80 | 67 |
| New listings | 161 | 240 |
| Active listings | 322 | 339 |
| Months of inventory | 4.08 | 5.06 |
| Median days on market | 24 | 28 |
What the numbers mean for buyers and sellers
Rising supply and longer marketing times typically shift bargaining power toward buyers, and the September figures suggest that dynamic is emerging in Newmarket. An increase in months of inventory from 4.08 to 5.06 indicates it would take more time to clear current listings at the recent sales pace, while a longer median time on market suggests properties are taking slightly longer to sell.
For sellers, the data underlines the importance of pricing and presentation if they hope to attract attention in a market where more choice is available. For buyers, the uptick in listings could mean more negotiating room than earlier in the year.
Local context, cautious interpretation
Local realtors caution that one month does not establish a lasting trend. Gizzie said September interrupted a recovery that had been taking shape earlier in 2026, but stressed the market can shift again as economic conditions and buyer sentiment change.
For Newmarket residents keeping an eye on housing, the September data is a reminder that local markets can diverge from regional averages. While the GTA saw price and listing declines year over year, Newmarket experienced a short-term increase in supply and a pullback in sales compared with August.
Observers will be watching coming months for signs of whether Newmarket’s September slowdown is a brief pause or the start of a broader shift as the autumn market unfolds.
