Canada's Mortgage Renewal Wave Peaks as Toronto Delinquencies Surge 45% Year-over-Year
The highly leveraged Canadian household sector is navigating the peak of its multi-year mortgage renewal wave, with high interest costs translating into severe localized credit deterioration.1 Fresh analysis from the Canada Mortgage and Housing Corporation (CMHC) released in May 2026 highlights that beneath a stable national surface, significant regional stress is building.
The CMHC reports that residential mortgage debt crossed the $2.4 trillion mark as of December 2025 (up 4.8% YoY), with renewal activity dominating the industry. While renewal volumes are expected to ease slightly through the rest of 2026 as borrowers who took out 3-to-5-year mortgages in the early 2020s complete their transitions, the financial shock remains severe. The vast majority of renewing borrowers face massive increases in interest expenses, prompting a shift toward shorter mortgage terms and variable rates to hedge against rate uncertainty.
This payment shock has driven up delinquency rates. The national 90+ day mortgage delinquency rate edged up to 0.24% in Q4 2025 (up from 0.21% a year earlier). However, this national average masks acute regional crises. The rise in arrears is being heavily driven by Ontario and British Columbia. Specifically, mortgage delinquencies in Ontario surged by 35% year-over-year, while delinquencies in the Toronto Census Metropolitan Area (CMA) skyrocketed by 45% year-over-year.
These figures align with Equifax Canada’s reports of rising consumer insolvencies and credit card delinquencies, indicating that the household "wealth buffer" in major urban centers is rapidly depleting as the renewal wave collides with higher-for-longer interest rates.
