September’s Fragile Market: What the Latest Canadian Housing Data Actually Shows

The Housing Evidence Brief

The issue in brief

A reader in Ontario asked: “I keep hearing the housing market is recovering and also that it’s weakening. Which is it, and what should I actually watch this fall?”

Both impressions have support. September 2026 data shows weaker national resale demand, roughly steady construction, and higher fixed mortgage rates. The important distinction is between what the data confirms, what it cannot show, and what remains a forecast.

What the September resale data says — and how it is defined

The most recent national market report, dated October 16, 2026, describes September as further evidence that the recovery remains fragile (WOWA Canadian Housing Market Report, October 16, 2026).

• Seasonally adjusted sales fell 2.3% from August, or month over month. Seasonal adjustment removes normal calendar patterns, so this decline is not explained simply as a routine end-of-summer slowdown.
• New listings declined 1.8% from August.
• The sales-to-new-listings ratio slipped to 48.8%, a measure of balance between buyers and sellers.
• The national benchmark price declined 0.4% month over month on a seasonally adjusted basis.

These are seasonally adjusted, month-to-month figures. They are not year over year comparisons, and they are not the unadjusted figures that other coverage may quote. Mixing definitions can make the same market appear stronger or weaker than it is.

Regional qualification: this is not one national market

The national figures conceal substantial provincial variation. Ontario and British Columbia continue to experience weaker pricing conditions, while several Prairie and Atlantic provinces remain more resilient. Ontario is described as a buyer’s market, with 5.4 months of supply in September 2026. Months of supply estimates how long current inventory would take to sell at the recent sales pace.

A national headline such as “Canadian prices slip” may describe Ontario and B.C. accurately while missing conditions in Manitoba, Saskatchewan, or the Atlantic provinces. National data is useful context, not a description of every city or neighbourhood.

The construction side: a genuine contradiction

The “recovering” and “weakening” narratives also both appear in construction data. The seasonally adjusted annual rate of housing starts rose approximately 3% from August to 248,896 units in September. However, the six-month trend rose only 0.6% to 250,411 units, suggesting that the underlying pace remained essentially flat (CMHC housing data and sources).

Other reported supply indicators were weaker:

• Actual starts in centres with populations of at least 10,000 were 11% lower than September 2025.
• During the first nine months of 2026, starts were down 4% from the same period last year.
• Approximately 371,617 housing units remained under construction in larger urban centres.
• Monthly completions totalled 17,398 units, down 0.9% from August.

The tension is clear: resale demand is constrained by affordability and borrowing costs, while Canada still faces a long-term supply shortage. CMHC estimates annual starts would need to reach approximately 417,000 to 469,000 units to restore affordability to pre-pandemic levels by 2036, well above the current pace. Weak demand today could discourage development and reduce supply several years from now.

Mortgage rates: confirmed moves versus forecasts

Confirmed developments as of mid-October include the following:

• All six of Canada’s largest banks raised select fixed mortgage rates since early September. CIBC raised several fixed rates on October 9, following BMO increases to its three-year and five-year fixed rates on October 7 (October 2026 mortgage-rate report).
• The five-year Government of Canada bond yield, a key benchmark for fixed mortgage pricing, reached a 52-week high near 3.73% on September 28 before easing to approximately 3.56% by October 9.
• CMHC estimates that approximately 1.15 million Canadian mortgages are set to renew in 2026 and another 940,000 in 2027.
• A rate snapshot dated October 17 showed average five-year fixed rates among a 10-lender basket at 4.92%, up 18 basis points over 30 days. The lowest advertised five-year fixed rate was 4.39%. Advertised rates change without notice and depend on lender, term, and borrower qualification.
• The Bank of Canada policy rate stood at 2.25%, unchanged since September 2, according to a forecast update dated October 9 (Canada mortgage-rate forecast).

The outlook is less certain. Most economists at Canada’s largest banks expected the policy rate to hold through year-end, with the first increase expected in 2027. Money markets were pricing roughly 100 basis points of Bank of Canada increases over the following 12 months. That is market pricing, not a commitment.

Forecasts also differ. Scotiabank projected a policy rate of 2.50% by the end of 2026, while National Bank expected 2.25% through 2026 before a rise to 2.75% by the end of 2027. The September Consumer Price Index release on October 19 was identified as the next major catalyst; August headline inflation was 3%.

What the 2026 forecasts say

CREA’s July 2026 forecast expected 463,336 residential sales in 2026, a 1.4% decline from 2025, and a 1.1% increase in the national average price to approximately $686,710. CMHC’s Summer 2026 outlook was more cautious, projecting approximately 457,200 sales, an average price of approximately $675,200, and 241,400 housing starts. It attributed weaker demand to slow economic growth, weaker population growth, elevated borrowing costs, and economic uncertainty, with improvement expected in 2027 and 2028 (CMHC Housing Market Outlook 2026).

CMHC’s regional overview says resale markets should recover but remain below long-term averages. It also expects starts to slow in 2026, with a larger decline in 2027–2028, while rental affordability improves as high vacancies and slower rent growth persist. Forecasts are scenarios, not promises about any particular city.

What this data cannot show

• National figures cannot identify conditions in a specific neighbourhood or price segment.
• Benchmark and average prices measure different things; averages can change because of the mix of homes sold.
• The sales-to-new-listings ratio describes market balance, not future prices.
• Renewal counts do not determine an individual household’s payment; that depends on its term, rate type, and qualification.
• Forecasts depend on inflation, policy decisions, and economic growth that have not happened yet.

A practical next step for readers

If your mortgage renews within 12 months, check your renewal date and current rate, then compare your lender’s offer with other lenders when your renewal window opens. Offers vary, and you are not required to accept the first offer from your current lender. For general information on housing conditions and mortgage research, consult CMHC’s housing research and data portal.

If you are monitoring the market, note the October 19 CPI release and the Bank of Canada’s October 28 rate announcement. Those releases should clarify the rate picture more than a single national price headline.

Uncertainty boundary

This issue reflects information available in mid-October 2026. September figures may be revised. Rate forecasts are opinions and market pricing, not commitments.
