Ontario Mortgage Arrears Hit 0.32% and Will Keep Rising to Mid-2027, CMHC Warns GTHA and Southwestern Owners

The headline figure and the forecast window

The core finding is short. According to CMHC's October 27 release, Ontario's arrears rate reached 0.32% in Q2 2026 and, while still below historical peaks, is expected to continue rising through mid-2027. CMHC counts a mortgage as in arrears once payments are 90 days or more past due.

The forecast is regional, and that is the point. Ontario is the outlier. Other provinces are moving sideways or improving.

The two-sided message

CMHC is careful not to call this a crisis. The same release says the largest renewal shock has likely passed, new lending carries a lower risk profile, and banks' provisions for potential losses remain low relative to their mortgage portfolios.

Deputy Chief Economist Aled ab Iorwerth framed it plainly: "Canada is not facing a broad mortgage crisis." His caution came in the next breath. Pressure, he said, is concentrating in specific regions and appearing first in other debts, and the early warning signs in parts of Ontario need close monitoring.

Hold both ideas at once. The system is stable. Specific households in specific places are not.

CMHC's accompanying podcast summary adds two details. Ontario delinquency rates are approaching levels last seen around 2008, and Toronto is the city most exposed to further pressure. Among mortgage investment entities, the smaller private lenders that serve more financially vulnerable borrowers and hold about 1.8% of outstanding balances, the GTHA delinquency rate is more than three times the rest of Canada's. CMHC describes that segment as small and not systemic.

The Ontario trend has been building for a while. Our earlier coverage tracked it through the TransUnion Q2 data showing Ontario delinquencies rising six basis points.

Arrears are a lagging indicator

A 90-day threshold means arrears capture the end of a long process, not its start. CMHC's Ask an Expert explainer on mortgage arrears describes the usual sequence: households cut spending, draw down savings and lean on credit cards or lines of credit before they miss a mortgage payment. Delinquency then moves through 30, 60 and 90 days late. By the time a mortgage reaches the statistic, the safety nets are often already worn through.

That is why the provincial rate is a poor gauge of personal risk. It tells you how many Ontario mortgages crossed the 90-day line. It says nothing about whether yours will. Your own risk is set by your income stability, your other debts, your equity and when your term ends.

Why the stakes rise once a payment is missed

CMHC's explainer is direct about the consequences. Canadian mortgages are usually recourse loans, so a lender can pursue other assets after a default. Arrears can also damage a credit score, narrow borrowing options and make it harder to switch lenders at renewal.

That last point is the hinge for everything that follows. Many of the tools that help a stretched owner, including refinancing and moving to a better rate, depend on still looking like a good borrower. A missed payment closes doors that were open the month before.

Arrears are not the same as losing the home

Context matters here, and the data is reassuring. Desjardins Economics noted in July that Ontario had nearly 60,000 mortgages in arrears last year, while Teranet recorded fewer than 3,000 properties changing hands under power of sale. Most cases are worked out with the lender through repayment plans, capitalized payments, longer amortizations, a co-borrower or a voluntary sale.

The lesson is not that arrears are harmless. It is that the lender conversation is where most outcomes are decided, and that conversation goes better earlier.

Jobs first, arrears later

Mortgage arrears follow employment, with a delay. The Canadian Bankers Association, citing Bank of Canada research, puts it in numbers: a one-percentage-point rise in unemployment leads to roughly a 0.1-point rise in the arrears rate, about a year later. The same source reports a national bank arrears rate of 0.29% as of July 2026, near historic lows. That figure covers large banks only and is not directly comparable to CMHC's broader data.

The lag explains the shape of CMHC's forecast. Job losses in 2026 become arrears in 2027.

The September job numbers

The latest labour data points the wrong way for Ontario. Statistics Canada's September Labour Force Survey showed national employment down 68,000 and unemployment up to 6.5%. Ontario's unemployment rate reached 7.0%, with employment down 20,000. Manufacturing shed 13,000 jobs nationally.

CMHC's language on causation is deliberate. Trade tensions are "contributing to" labour-market uncertainty alongside softer housing conditions. They are one driver, not the only one.

Windsor, London, Kitchener-Waterloo and Hamilton

These four communities sit inside CMHC's exposure zone for the same structural reason: a meaningful share of local paycheques flows from manufacturing, auto assembly or the supplier chains behind them. CMHC's release does not break out city-level arrears forecasts for them, and official city-level figures were not part of this report, so treat the exposure as structural rather than measured.

What that means in practice is simple. If your household income depends on an auto plant, a parts supplier, a steel or metal fabricator, or a logistics firm serving them, your risk profile is different from a neighbour's in health care or government. The provincial number averages you together. Your lender will not.

• Windsor: auto assembly and tool-and-die work tied directly to cross-border trade.
• London: auto parts and other manufacturing alongside a large public and health-care sector.
• Kitchener-Waterloo: a technology base, but also auto assembly and advanced manufacturing that ship to the U.S.
• Hamilton: steel and metals, with GTHA housing costs layered on top.

Equity matters here as well. Falling prices in the GTA have thinned the cushion that makes refinancing possible, a trend we covered when the GTA benchmark slipped 6.7%.
