King is a 20-sale market, and in a market this size the average price tells you which homes sold, not what homes are worth. September's average was $1,875,750, up 6.2% from last September. The median was $1,710,000, up 4.0%. The detached median, which is 16 of the 20 sales, was up 0.3%. Flat is the plainer read on prices.
. The average fell 8.7% to $1,139,770 and the median fell 8.3% to $1,050,000, both moving together, so this isn't a mix story. Detached, which is 63% of what sells here, repriced 8% on the average and almost 10% on the median across 26 sales. The homes that did sell went quickly, 35 days against 44 in August, and semis and townhouses closed above asking. Fewer buyers, but the ones who showed up were decisive. The GTA-wide picture is in our September 2026 Market Watch post.
Vaughan's average sale price in September 2026 was $1,163,441. In September 2025 it was $1,163,498. Fifty-seven dollars apart, on 213 sales. We've been doing this a long time and we don't remember a cleaner year-over-year flat line. It's also almost entirely a coincidence, because underneath that number the two Septembers look nothing alike.
Prices came down together this time. The average slipped 3.7% year over year to $1,136,650 and the median fell 4.1% to $1,043,000. In August the average held while the median dropped; in September both moved, and the detached share of sales was the same 54% it was a year ago, so there's no mix story to hide behind. The softness sits below the detached tier: semi-detached, condo townhouse and condo apartment medians are all down roughly 11% to 14%.
Newmarket had a slow September. Sixty-four homes sold, down 22.9% from last September and 22.9% from August, tied with March for the lowest count since February. The average price fell 8.6% year over year to $915,986, the first time it's been under $920,000 since January. The median held better at $872,500, down 5.2%. New listings jumped 46% from August to 234, the biggest fall listing wave of any large York Region market, and the sales-to-new-listings ratio slipped for the first time since ...
Richmond Hill is the one large York Region market where prices actually moved this year, and September made that plain. The average sale price fell 10.2% from last September to $1,189,203 and the median fell 10.1% to $1,079,000. Both numbers moving by the same amount means this isn't a mix effect or a thin month at the top. Detached homes, half of everything that sells here, repriced about 11% on both the average and the median across 84 sales. That's a real reset.
Last month Aurora posted an 18.7% drop in its average price and we spent most of that update explaining why the number was a mix effect rather than a collapse. September is the proof. The average came in at $1,165,686, down just 1.5% from last September, and the median rose 5.5% to $1,081,500. Against August, the median jumped almost 15%. Nothing changed about Aurora's homes between August and September. What changed is which ones sold.
The average fell 4.4% from last September to $1,125,353 and the median dropped 8.0% to $1,051,000. Detached held almost flat on the average, and everything below detached fell 10% or more on the median. So you have the tightest supply in York Region, 4.1 months of inventory, sitting next to a median decline that only Richmond Hill and Stouffville exceeded this month. Those two facts aren't in conflict. That's what the early part of a turn looks like: inventory burns off first, prices move last.
Vaughan's real estate market moved in two directions this August. The average sale price climbed 2.0% year over year to $1,234,758, but the median price actually fell 2.6% to $1,148,750. That gap tells you something important about where buyers were spending their money. Detached homes, which accounted for half of all sales, saw their average jump 4.2%, and that higher-priced mix pulled the overall average upward even as most other segments slipped. Meanwhile, the sales-to-new-listings ratio...
Markham's sales-to-new-listings ratio crossed 40%, the line TRREB uses to separate a buyer's market from a balanced one. It is the first municipality in York Region to get there, and it did not get there because of a sales surge. It got there because supply keeps thinning out while buyers keep showing up. That same pattern played out across the region at different speeds, pushing the overall SNLR to 35.8%, its eighth straight monthly increase.
