Mortgage Stress Is Rising in Ontario — Here’s What It Means for You

If you’re carrying a mortgage in Ontario right now, you’re not imagining it: the pressure is real, and the numbers back it up. New data from TransUnion Canada shows that mortgage delinquencies are ticking higher across the country’s priciest housing markets — and Ontario is leading the trend.

Here’s a plain-language breakdown of what’s happening, why it’s happening here first, and what it means if you’re a homeowner, buyer, or renewing your mortgage in the months ahead.

The numbers: Ontario is feeling it most

Nationally, mortgage delinquencies are still low. As of Q2 2026, only 0.31% of mortgage balances across Canada are 60 or more days past due — a small uptick of six basis points from a year earlier. That sounds reassuring, and in the big picture, it is: 99.7% of mortgage holders are still current on their payments.

Ontario’s balance-level rate rose 10 basis points year over year, the largest increase of any province. Its account-level delinquency rate also recorded the biggest provincial jump. B.C. saw a similar direction of travel, while Quebec’s rates were flat or improved slightly.

As TransUnion’s Matt Fabian explained, borrowers in higher-cost markets tend to carry larger mortgage balances and face greater exposure to affordability pressure. Put simply: bigger mortgages mean bigger monthly payments and less cushion when rates, income, or expenses shift.

Who’s most affected?

If you got your mortgage — or renewed — during 2022 or 2023, this data is especially relevant. That was the window when interest rates rose fastest, and borrowers who locked in or renewed during that stretch are still feeling the affordability squeeze. TransUnion notes that this group, particularly a smaller subprime segment, continues to show higher delinquency rates than borrowers who took out mortgages more recently.

The good news: mortgages originated in 2024 are performing noticeably better, a sign that recent underwriting and the current rate environment are giving newer borrowers more breathing room.

New borrowing is slowing down, too

It’s not just delinquencies — the pace of new mortgage activity is cooling as well. Mortgage originations grew 7.8% year over year in Q2, a solid number on its own, but a real slowdown from the double-digit growth rates seen previously. Affordability challenges, economic uncertainty, and cautious buyer sentiment are all being cited as reasons.

Interestingly, the average size of a newly issued mortgage dropped 2.4% to $354,683. That likely reflects buyers being more strategic — choosing less expensive homes, putting more money down, or looking outside the priciest markets to make the numbers work.

Meanwhile, total mortgage debt across Canada climbed to $1.93 trillion, even though the total number of mortgage accounts dipped slightly. In other words: fewer people are taking out new mortgages, but the borrowers carrying debt are carrying more of it.

What this means if you’re in Ontario

None of this is cause for panic — the vast majority of homeowners are still managing their payments. But if you’re in Ontario, here’s why this data matters to you:

• If you’re up for renewal soon, especially if your current rate was locked in during 2022–2023, get ahead of your options rather than waiting for your renewal notice. A proactive conversation can uncover savings or a better structure before you’re under pressure.
• If you’re feeling squeezed by your current payment, you’re far from alone. Refinancing or restructuring your amortization may help ease monthly cash flow, depending on your situation.
• If you’re buying in today’s market, build in a real affordability cushion rather than simply qualifying for the maximum amount available.

The bottom line

Mortgage stress in Ontario isn’t a crisis — but it is a trend worth paying attention to. The households feeling the pinch are largely those who bought or renewed at the peak of the rate cycle, and the gap between them and more recent borrowers is widening. Whether you’re renewing, refinancing, or just want a second opinion on where you stand, now is a smart time to check in.
