Key takeaway: A recent Bank of Canada analysis indicates that nearly 10% of Toronto mortgage holders may fail to meet the OSFI mortgage stress test qualification requirements when attempting to refinance in 2027. This stems from a combination of elevated property values, higher interest rates compared to when these mortgages were originally taken out, and stricter qualifying rules. Affected homeowners face the choice of staying with their current lender at renewal (potentially at less favourable rates), paying down principal to improve their loan-to-value ratio, or exploring alternative lending options.

What the Bank of Canada Finding Reveals

The Bank of Canada’s October 2026 analysis highlights a growing challenge for Toronto mortgage holders approaching renewal. Under the OSFI B-20 mortgage stress test, borrowers refinancing with a new lender must qualify at the higher of the contract rate plus 2 percentage points or the current benchmark qualifying rate (as covered in foundational mortgage finance texts such as Principles of Finance). According to the Bank of Canada, close to 10% of Toronto mortgage holders who need to refinance in 2027 will not meet this threshold based on their current income, debt levels, and property values.

This figure is significantly higher than the national average, reflecting Toronto’s elevated home prices and the large number of mortgages originated between 2020 and 2022 when rates were at historic lows. Many of these borrowers qualified under much lower stress test rates and are now facing substantially higher qualifying benchmarks when their five-year terms expire.

Why Toronto Is Particularly Affected

Toronto’s housing market saw rapid price appreciation through 2021 and early 2022, with many buyers stretching their budgets to enter the market. Borrowers who purchased with minimal down payments (requiring CMHC mortgage default insurance) or those with combined loan-to-value ratios near the maximum now face a qualification gap.

When refinancing with a new lender, the stress test applies the current qualifying rate to your remaining mortgage balance. Even if your home’s value has held steady or increased, rising interest rates mean the income required to qualify has jumped substantially. A mortgage that was comfortably within reach at a 1.5% contract rate in 2021 now requires qualification at 5% or higher in the current environment (as of October 2026, rates and qualifying benchmarks change frequently, verify current terms with a licensed mortgage professional before deciding).

What Happens If You Don’t Qualify to Refinance

If you cannot pass the stress test with a new lender, you are not forced into default. You retain the right to renew with your existing lender, even if you no longer meet the stress test criteria. However, this removes your negotiating leverage. Your current lender knows you cannot easily switch, which may result in a renewal offer at a higher rate than what competitive lenders would provide to a fully qualified borrower.

According to the Financial Consumer Agency of Canada, mortgage renewal is the point at which you renegotiate your mortgage term with your existing lender or transfer to a new one. If you stay with your current lender, the stress test does not apply. The trade-off is that you may pay a rate premium compared to shopping the market.

Steps to Improve Your Refinancing Position

Homeowners approaching renewal in 2027 who are concerned about qualification can take proactive steps:

  • Pay down your mortgage principal ahead of renewal. Even a modest lump-sum prepayment can improve your loan-to-value ratio and reduce the income needed to qualify.
  • Reduce other debts. Your total debt service ratio factors in all credit obligations. Paying off credit cards, car loans, or lines of credit can free up qualifying room.
  • Work with a licensed mortgage broker several months before your renewal date. A broker can assess your qualifying position early and help you explore options with multiple lenders or private financing if needed.
  • Review your prepayment privileges now. Most closed mortgages allow annual prepayments of 10% to 20% of the original principal without penalty. Use this room strategically if you have available cash.

Eligibility, limits, and prepayment options vary significantly by lender, mortgage product, and your specific circumstances. Consult with a licensed mortgage broker or your financial institution for personalized guidance based on your situation.

What This Means for the Broader Canadian Market

While Toronto shows the highest concentration of affected borrowers, other major markets with elevated home prices and high mortgage debt levels, including Vancouver and parts of the Greater Toronto Area suburbs, face similar pressures. The 2026-2027 period represents a massive renewal wave across Canada, with hundreds of thousands of mortgages originated at record-low rates during the pandemic coming up for renewal.

The OSFI stress test is designed to ensure borrowers can withstand rate increases and economic shocks, a principle recognized in mortgage underwriting practices. For the subset of borrowers who no longer meet current qualifying standards, the options are to stay with their lender, improve their financial position, or seek alternative financing.
