In September 2026, the average Innisfil home that sold had been on its current listing for 44 days. The same homes had been on the market for 68 days. The 24 days between those two numbers don't show up on a listing page. They matter more than the average price for a buyer shopping Innisfil against Barrie or Bradford this fall.
Both figures come from the Toronto Regional Real Estate Board's September 2026 Simcoe County Market Watch, released October 15. It is the most recent monthly report TRREB has published for the county.
The 24 days that reset when a home is relisted
TRREB tracks two clocks. Listing days on market counts how long a sold home sat on the listing that actually sold. Property days on market keeps running through relists. The board defines it this way:
"the average number of days a property was on the market before selling, irrespective of whether the property was listed more than once by the same combination of seller and brokerage during the original listing contract period."
When the two numbers drift apart, homes are being taken down and put back up before they sell. In Innisfil the gap averaged 24 days across September's sold homes. That is an average, so some homes sold on their first listing and others carried much longer histories. The definition also has a limit. It covers relists by the same seller and the same brokerage. It doesn't say whether a home relisted through a different brokerage carries its old days forward.
For a buyer, a listing that shows three weeks on market may have been available, at some price, for much longer. That history shapes how a seller thinks about an offer.
Innisfil carries more supply than its neighbors
The relisting gap follows directly from how much is for sale here compared with how much is selling. September's figures for Innisfil and the markets buyers most often compare it with:
| September 2026 | Sales | New listings | Active listings | Sales-to-new-listings ratio | Months of inventory | Listing days | Property days | Gap |
|---|---|---|---|---|---|---|---|---|
| Innisfil | 56 | 211 | 413 | 27.1% | 7.3 | 44 | 68 | 24 |
| Barrie | 130 | 513 | 888 | 33.1% | 5.2 | 40 | 59 | 19 |
| Bradford | 44 | 99 | 177 | 41.6% | 4.4 | 35 | 51 | 16 |
| Essa | 25 | 78 | 136 | 35.7% | 4.9 | 43 | 59 | 16 |
| Simcoe County | 611 | 2,147 | 4,305 | 32.5% | 6.3 | 46 | 64 | 18 |
Two columns matter more than they appear to. TRREB calculates the sales-to-new-listings ratio and months of inventory as 12-month moving averages. Innisfil's 27.1% doesn't describe one slow September. Over a full year, roughly one home has sold for every four that came to market. Bradford, directly south along the same commuter corridor, has run closer to two in five.
September alone matches that pattern. In Innisfil, 211 new listings came to market against 56 sales, and 413 homes were still active at month-end. At September's pace, that active inventory would take about seven months to clear, which lines up with the 7.3 months TRREB's trend figure shows.
Sellers in a market that crowded try things. They lower the price, refresh the photos, or pull the listing and bring it back. Each relist resets the clock buyers see. Bradford and Essa share a 16-day gap, and Innisfil's is half again as wide.
The pile is shrinking faster than buyers are leaving
The year-over-year figures point somewhere less comfortable for buyers.
Compared with September 2025, Innisfil's active listings fell 16.7% while sales fell only 6.7%, as Simcoe.com reported from the TRREB data. Inventory is shrinking more than twice as fast as demand. The glut is still large, but it is getting smaller.
The average price moved the same way. Innisfil averaged $747,652 in September 2026, down 4.9% from a year earlier but up 0.8% from August. The median was $707,500. Homes that did sell closed at an average of 97% of list price, one point below Barrie and Bradford.
TRREB's county-wide commentary describes the same tension. Across Simcoe County, sales fell further than new and active listings, which the board said gave buyers "more choice and negotiating power in some segments of the marketplace." It also noted that some would-be buyers were waiting on the sidelines for more certainty on US trade and inflation, after a recent uptick in fixed mortgage rates.
Put together, Innisfil's buyer leverage is real and comes from a full year of oversupply. That oversupply is draining. If the buyers who are waiting come back while active listings keep falling at this rate, the room to negotiate can narrow quickly. The best evidence of how much room remains on a particular home is its listing history.
Ten sales cannot carry a trend
The same report shows a second trap. Innisfil is small enough that its segment averages rest on very few sales.
- Detached homes made up most of the market, with 45 sales at an average of $777,023 and 328 active listings. That average was down 2.4% from August and 4.2% from September 2025.
- Attached homes averaged $640,346, up 13.7% year over year. That figure comes from 10 sales against 37 active listings.
- Apartment-style condos averaged $499,000, down 21.4% year over year. That figure comes from a single sale, with 44 condos still active at month-end.
A 13.7% jump on 10 transactions could reverse next month because of which ten homes happened to sell. A 21.4% drop on one condo sale tells you about one condo. The detached figures are the only Innisfil segment with enough volume to show a direction, and they match the town-wide story of slightly softer prices and long time on market. With 328 active detached listings against 45 sales, detached supply alone works out to about seven months at September's pace.
For condo buyers, the clearest signal is the ratio itself. With 44 active listings against one September sale, condo sellers face very little competition from other buyers.
Reading an Innisfil listing on the full clock
Since the listing clock can reset, the useful questions are about history rather than the current listing. Before writing an offer in Innisfil this fall, it helps to know:
- When the property first came to market in its current selling effort, and whether it has been relisted since.
- What it was first listed at, and how many times the price has changed along the way.
- Whether the listing brokerage has changed, since TRREB's property-days definition is written around the same seller and brokerage.
- How the home compares with nearby active listings, given that the town had roughly seven months of supply at the end of September.
- Which segment it belongs to, so a 10-sale attached average or a one-sale condo figure doesn't end up anchoring the price.
None of these questions assumes a seller will accept less. Some homes relist after a deal collapses, and some sellers simply misjudged timing. The history tells you which situation you're in, and the days-on-market figure on the listing page won't.
FAQ
Is Innisfil a buyer's market right now? As of TRREB's September 2026 data, Innisfil had 7.3 months of inventory and a 27.1% sales-to-new-listings ratio, both 12-month moving averages. That is looser than Barrie, Bradford, Essa, and the Simcoe County average. Active listings also fell 16.7% year over year while sales fell 6.7%, so the supply cushion is shrinking.
Why are there two days-on-market numbers? Listing days count time on the listing that sold. Property days count total time on the market across relists by the same seller and brokerage. In September 2026, Innisfil's figures were 44 and 68.
Do Innisfil homes sell far below asking? Not on average. In September 2026, sold homes in Innisfil closed at 97% of list price. A home's full listing history shows whether its asking price changed before that final sale.
