In the face of ongoing worries about the weakening real estate markets in Ontario and British Columbia, Canada’s major banks have demonstrated an unexpected robustness in their mortgage portfolios. Recent data reveals that the Big Six banks collectively wrote off a mere $38 million from a staggering $1.76 trillion in mortgages between November 1, 2025, and January 31, 2026. This figure represents just 0.01 per cent of their total mortgage holdings, indicating a level of stability that many analysts had not anticipated.
Low Default Rates Bolster Bank Fortunes
One of the primary reasons for the banks’ impressive performance is the remarkably low rate of mortgage defaults. As of December 2025, only 0.24 per cent of mortgage holders were more than three months behind on their payments. This resilience can largely be attributed to Canada’s stringent regulatory framework, particularly the mortgage stress test, which necessitates that borrowers qualify at higher rates than those of their actual contracts. This requirement creates a safety net, ensuring that borrowers are financially prepared for potential economic shocks.
Moreover, Canadian homeowners tend to go to great lengths to avoid defaulting on their mortgages. With the understanding that lenders can pursue other assets to recover outstanding debts, borrowers remain motivated to keep their payments current, further stabilising the banks’ mortgage portfolios.
Risk Distribution Among Lenders
Another significant factor contributing to the stability of the Big Six banks is the uneven distribution of risk across the mortgage lending landscape. These banks have strategically avoided the riskier segments of the mortgage market. The national mortgage arrears rate remains at a low 0.24 per cent, in stark contrast to the much higher rate of 2.01 per cent seen in mortgage investment corporations. This discrepancy highlights the disciplined underwriting practices adopted by the major banks, which have enabled them to sidestep much of the risk that plagues less cautious lenders.
When analysts discuss mortgage risk in Canada, they are often referring to these more vulnerable segments of the market, which the Big Six have consciously chosen to avoid.
Protective Measures and Insurance Backing
Even in instances where borrowers do default, the potential losses for banks are mitigated by the comprehensive Canadian mortgage insurance requirements. Borrowers who make a down payment of less than 20 per cent are mandated to carry default insurance, effectively transferring the risk away from lenders to insurance providers such as Canada Mortgage and Housing Corporation. For those who can afford larger down payments, the equity built into their properties serves as a robust buffer. This allows banks to recover outstanding balances through property sales, even in the event of market downturns.
Significant losses for banks only become a concern during extreme price drops that approach the size of the initial down payment. However, recourse provisions empower lenders to pursue borrowers’ other assets, further decreasing the likelihood of substantial losses.
The Big Picture: A Stable Mortgage System
The resilience displayed by Canada’s Big Six banks amidst real estate uncertainties reflects the strength of the country’s mortgage system. With near-zero write-offs against a multi-trillion-dollar portfolio, these institutions not only navigate the current market challenges but also maintain a profitable business model centred around residential mortgages.
Dr. Hanif Bayat, CEO and founder of WOWA.ca, a Canadian personal finance platform, highlights the importance of this stability, noting that for these banks, residential mortgages remain one of the safest and most reliably profitable asset classes available.
Why it Matters
The findings regarding the Big Six banks underscore the broader health of Canada’s mortgage system, providing reassurance to investors and stakeholders alike. As the real estate landscape continues to evolve, the prudent practices adopted by these institutions not only safeguard their financial wellbeing but also contribute to overall economic stability. This scenario serves as a reminder of the importance of regulatory frameworks and risk management strategies in fostering a resilient banking sector capable of weathering market fluctuations.
