Welcome to your Week of September 28, 2026 GTA real estate update. Ten days ago I wrote that tame core inflation had lowered the odds of an October rate hike. The bond market has since disagreed. Traders now treat the Bank of Canada’s October 28 decision as a coin flip, fixed mortgage rates have already moved higher, and the national housing data shows a market that has stopped falling but is bracing for headwinds. This week’s spotlight heads north to Innisfil and Barrie, where prices are actually up year-over-year.
Why a Hike Is Suddenly a Real Possibility
The overnight rate is 2.25%, where it has sat through seven straight holds. On September 16, the Bank released its summary of deliberations from the September 2 decision, and the tone was more cautious than the hold suggested. Governing council was worried that high gasoline prices tied to the war in Iran would eventually spread into other prices, and it discussed possibly adjusting the policy rate at future meetings. BNN Bloomberg reported that market odds of an October hike reached 60% that afternoon, the same day the U.S. Federal Reserve delivered its first rate hike in three years.
By September 18, markets saw October as a coin flip leaning slightly toward a hike. Economists are more cautious. Desjardins and RBC both expect the Bank to hold for the rest of 2026 and hike in early 2027, and Capital Economics’ base case is no October hike, though it calls it a close call. The counterweight is trade: the U.S. imposed 50% tariffs on roughly $28 billion of Canadian goods on August 22, and the Bank worries that will weigh on hiring and spending.
What this means at the mortgage desk: You don’t have to wait for October 28 to feel this. Fixed rates track the five-year Government of Canada bond yield, which has been sitting near a 52-week high around 3.3–3.4%. Lenders raised three- to five-year fixed rates by roughly 5 to 20 basis points this month, and the lowest advertised five-year fixed rates are now around 4.2–4.3%, per rate-comparison sites. Variable-rate borrowers face the direct risk if the Bank moves. If you’re shopping, get a rate hold in writing now.

Headlines I’m Watching This Week
- National sales flatlined for a fourth month. CREA reported August sales down 0.7% month-over-month and 6.9% below last year, while new listings jumped 3.3% as sellers got an early start on the fall market. The MLS® HPI was flat month-over-month and down 3% year-over-year, the smallest annual drop since October 2025. With 4.8 months of inventory, the national market is balanced. CREA’s senior economist pointed to higher fixed rates and hike risk as fresh headwinds heading into 2027. That’s the same message the bond market is sending.
- New low-rise homes keep selling. BILD reported September 22 that GTA single-family new home sales hit 692 in August, 47% above the 10-year average and the fifth straight month above it, which BILD credits to the HST rebate program. Condos are a different story: 215 units sold, up 50% from a record-low 2025 but still 78% below the 10-year average. The new single-family benchmark price is $1,248,866, down 14.6% year-over-year, as builders shift toward more affordable product. That puts new construction in direct competition with resale for the first time in a while.
- The fall supply picture. TRREB’s August Market Watch showed 5,057 GTA sales (−2.1%), an average price of $993,410, and new listings down 14.1%. September results arrive in early October. The key question is whether the national uptick in late-August listings reached the GTA.
Neighbourhood Spotlight: Innisfil & Barrie
This week I’m looking at Innisfil and Barrie, the Lake Simcoe corridor that has become the GTA’s value option for buyers who can handle the Highway 400 commute or the GO train. Unlike most of the 416 and 905, both markets are showing year-over-year price gains.
| Per Zolo (latest 28-day window) | Barrie (Aug 28 – Sep 25) | Innisfil (Aug 25 – Sep 22) |
|---|---|---|
| Average sold price | $676K (+4.6% YoY) | $720,133 (+7.3% YoY) |
| Detached average | $797K (+4%) | $752K (−7%) |
| Active detached listings | 622 (−24%) | 409 (−16%) |
| New listings (all types) | 498 | 228 |
| Median days on market | 37 | 41 |
| Sale-to-list ratio | 98% | 96% |
Barrie is the healthier market. Detached prices are up about 4%, active detached inventory is down 24%, and new detached listings are down 38% from last year. Homes are selling at 98% of asking. That’s the same supply squeeze we’ve seen across the GTA, and it’s a big reason prices are holding. The softness is in attached housing: Barrie townhouses averaged about $546K (−14%) and condos about $439K (−24%), with condos taking 54 days to sell.
Innisfil’s headline gain of 7.3% is partly a mix effect. Its detached average actually fell 7% to about $752K, and sales volume is thin, so a few townhouse sales can move the average. Read Innisfil as stable, not hot. The number that matters most here is from BILD: new single-family homes in Simcoe County sold at a weighted average of $1,032,483 in August, before any HST rebate. Barrie and Innisfil resale detached homes average roughly $750K–$800K, so resale is running about $230K–$280K below new construction. Even after rebates, many buyers will get more house for their money in resale.
This Week’s Takeaway
If you’re a buyer: the risk has shifted. For most of 2026 the question was when rates would fall. Now it’s whether they rise. Fixed rates have already gone up without the Bank doing anything. Lock in a pre-approval with a rate hold now, since most holds run 90 to 120 days and would carry you past October 28. If GTA prices are stretching your budget, Barrie detached homes near $800K, with 98% sale-to-list, offer value, but expect competition for well-priced homes.
If you’re a seller: national listings rose in late August, and TRREB’s September data will show whether that reached the GTA. If buyers get squeezed by higher rates, the ones who stay active will be more rate-sensitive and more careful on price. Get listed before any October rate shock and price to the last 30 days of sales. In Barrie and Innisfil, detached inventory is down 16–24%, which gives sellers leverage. In the condo segment you don’t have that leverage, so price for it.
If you’re an investor: plan for rate risk in both directions. Model 2.25% holding, but stress-test a 2.50–2.75% overnight rate by early 2027, since several forecasters see hikes coming. Resale is priced well below new construction in Simcoe County, and Barrie condos are down 24% year-over-year. That’s a buyer’s entry point for anyone whose rental math works at today’s fixed rates, but only if it works at today’s rates.
Bottom line for the week of September 28, 2026: The Bank of Canada is at 2.25%, and markets now price the October 28 decision as roughly a coin flip toward a hike. Oil-driven inflation risk and the Fed’s first hike in three years are the main drivers. Five-year bond yields are near a 52-week high, and the best five-year fixed rates are around 4.2–4.3%. CREA shows a flat, balanced national market (4.8 months of inventory). BILD’s August new single-family sales ran 47% above average. Barrie averaged ~$676K (+4.6%) and Innisfil ~$720K (+7.3%), with detached inventory down sharply in both. Buyers: lock a rate hold now. Sellers: list ahead of October with sharp pricing. Investors: stress-test for hikes and look for resale discounts.
FAQ
Will the Bank of Canada raise interest rates on October 28, 2026?
It’s uncertain. The overnight rate is 2.25% after seven straight holds. In mid-September, bond markets priced October as roughly a coin flip leaning toward a hike, driven mainly by high oil prices. Economists at RBC, Desjardins and Capital Economics expect a hold in October, with some pencilling in a hike in early 2027.
Why are fixed mortgage rates going up in September 2026?
Fixed rates follow the five-year Government of Canada bond yield, which has risen to near a 52-week high around 3.3–3.4% as markets price in possible hikes and global yields climb. Lenders raised three- to five-year fixed rates by roughly 5 to 20 basis points, and the lowest advertised five-year fixed rates are around 4.2–4.3% in late September.
What is the average home price in Barrie in September 2026?
Per Zolo data for August 28 – September 25, 2026, the average Barrie home sold for about $676,000, up 4.6% year-over-year, with a median of 37 days on market and a 98% sale-to-list ratio. Detached homes averaged about $797,000 (+4%), and active detached listings were down 24%.
What is the average home price in Innisfil in September 2026?
Per Zolo data for August 25 – September 22, 2026, the average Innisfil home sold for about $720,133, up 7.3% year-over-year, with a median of 41 days on market and a 96% sale-to-list ratio. Detached homes averaged about $752,000, down 7%, so the overall gain partly reflects a shift in the mix of homes sold.
How did Canadian home sales perform in August 2026?
CREA reported September 15 that national sales fell 0.7% month-over-month and were 6.9% below August 2025. New listings rose 3.3%, the sales-to-new-listings ratio eased to 49.1%, inventory was 4.8 months, and the MLS® HPI was flat month-over-month and down 3% year-over-year. The national average price was $668,219, up 0.6%.
