In October 2026, the Office of the Superintendent of Financial Institutions (OSFI) announced it would eliminate the mortgage stress test requirement at renewal for uninsured mortgages. Canadian homeowners with down payments of 20 per cent or more can now renew their mortgage with their current lender or switch to a new lender without having to requalify at the higher stress test rate. The Toronto Regional Real Estate Board (TRREB) and industry stakeholders welcomed the change as a measure that restores mobility and choice for borrowers while maintaining prudent lending standards for new mortgages.

What the Mortgage Stress Test Is

The mortgage stress test has been a cornerstone of Canadian mortgage regulation since OSFI introduced it in Guideline B-20 in 2018. According to the Office of the Superintendent of Financial Institutions, the stress test requires borrowers to qualify at the greater of the contract rate plus 2 percentage points or a minimum qualifying rate set by OSFI (OSFI, 2026). This means that if your lender offers you a mortgage at 5.5 per cent, you must prove you can afford payments calculated at 7.5 per cent.

The stress test applies to uninsured mortgages, those with a down payment of 20 per cent or more. Insured mortgages, where the down payment is less than 20 per cent and the loan carries CMHC mortgage default insurance, face a similar qualifying threshold under separate rules. The purpose of the stress test is to ensure borrowers can withstand rate increases when their mortgage term ends and they renew at potentially higher rates, as covered in foundational finance texts such as Principles of Finance.

For new mortgage applications and refinancing, the stress test remains in place. The recent OSFI change applies strictly to renewals, the moment when an existing mortgage term expires and the borrower negotiates a new term with the same lender or switches to a different one.

What Changed Under the New OSFI Rule

Before October 2026, homeowners renewing an uninsured mortgage faced the stress test if they wanted to switch lenders. If you had a mortgage at 4.0 per cent with Lender A and wanted to move to Lender B offering 3.5 per cent at renewal, Lender B treated you as a new applicant and required you to pass the stress test at 5.5 per cent or higher. Many borrowers, especially those whose income had not kept pace with home price appreciation or who had taken on other debts, could not meet that threshold. They remained locked in with their existing lender, even if that lender offered a less competitive rate.

Under the new rule, OSFI eliminated the stress test requirement at renewal for uninsured mortgages, whether the borrower stays with the current lender or switches. According to the Financial Consumer Agency of Canada, this change restores the flexibility borrowers had before 2018 and aligns the treatment of uninsured renewals with the way insured renewals have long been handled (FCAC, 2026). The borrower must still demonstrate they can afford the new payment at the contract rate, but they do not face the additional 2 percentage point buffer.

Critically, the stress test remains for new mortgage applications, refinancing to access equity, and any scenario where the borrower increases the loan balance. The change applies only to straight renewals where the mortgage balance stays the same or decreases through regular payments.

Why OSFI Made This Change

OSFI’s decision reflects a shift in the Canadian mortgage market and the recognition that the stress test, while effective at cooling demand and reducing default risk for new mortgages, created unintended consequences at renewal. During the 2020 to 2023 period, home prices in many markets rose sharply, and many borrowers took out mortgages at historically low rates below 2.0 per cent. By 2025 and 2026, as those mortgages came up for renewal, the Bank of Canada policy rate had risen to manage inflation, and contract rates climbed to 5.0 per cent and above.

Borrowers renewing in this environment faced payment increases of 50 per cent or more. The stress test, if applied at renewal, would have required them to qualify at 7.0 per cent or higher, a threshold many could not meet even though they had made every payment on time for years. Lenders reported that a significant share of renewal borrowers were effectively trapped with their current lender, unable to shop for better terms.

The Canada Mortgage and Housing Corporation and consumer advocacy groups argued that this lack of mobility reduced competition, allowed lenders to offer renewal rates above market, and penalized responsible borrowers who had built equity and maintained good payment histories (CMHC, 2026). OSFI concluded that removing the stress test at renewal for uninsured mortgages would restore borrower choice without materially increasing systemic risk, since these borrowers had already demonstrated their ability to service the debt over the initial term.

Who Benefits and How

The elimination of the stress test at renewal benefits uninsured mortgage holders, those with down payments of 20 per cent or more, who are coming to the end of a mortgage term in 2026 and 2027. If you took out a five-year fixed mortgage in 2021 or 2022 at 2.0 per cent and your term expires now, you can switch lenders to secure the best available rate without requalifying at the higher stress test threshold.

For example, if your current lender offers you 5.2 per cent at renewal but a competing lender offers 4.8 per cent, you can move to the lower rate as long as you can afford the payment at 4.8 per cent. Before the rule change, you would have had to qualify at 6.8 per cent (4.8 per cent plus 2 percentage points), which might have been out of reach if your income or debt load had changed.

Borrowers with insured mortgages, those with down payments below 20 per cent, do not see a change from this OSFI decision because the stress test rules for insured renewals are set separately and have been less restrictive. The benefit is concentrated among the segment of the market that had been most constrained: uninsured borrowers renewing during a period of rising rates.

What Homeowners Need to Know

While the elimination of the stress test at renewal opens the door to switching lenders, borrowers should still plan carefully. Moving from one lender to another at renewal incurs legal fees and possibly appraisal costs, typically C$1,000 to C$1,500. Some lenders offer to cover these costs as an incentive to switch, but not all do. Compare the rate savings over the new term against the cost of switching to ensure the move is financially worthwhile.

The rule change does not apply if you are refinancing to access equity or increasing your mortgage balance. In those cases, the full stress test still applies because you are effectively taking out new debt, not simply renewing the existing loan.

Mortgage products, rates, prepayment privileges, and penalties vary by lender and by province. As of October 2026, rates remain elevated compared to the 2020 to 2021 period, and the Bank of Canada policy rate remains a key driver of contract rates. Verify current terms with a licensed mortgage broker or your financial institution for your personal situation, and confirm whether any prepayment penalties apply if you break your current term early to refinance rather than waiting for renewal.

Limitations and Considerations

The OSFI change applies at renewal, the natural end of a mortgage term. If you are mid-term and want to switch lenders before renewal, you are refinancing, not renewing, and the stress test still applies. Refinancing mid-term also triggers prepayment penalties, often calculated as the greater of three months’ interest or the interest rate differential (IRD), which can be substantial if rates have fallen since you locked in your term.

Borrowers should also be aware that lender underwriting standards extend beyond the stress test. Even without the stress test at renewal, the new lender will assess your credit score, income stability, debt service ratios, and property value. If your financial situation has deteriorated significantly, the lender may decline the application or offer less favourable terms.

Finally, the rule is prospective. If you renewed before October 2026 under the old stress test requirement and were unable to switch, the change does not retroactively allow you to renegotiate. It applies to renewals processed under the new guideline going forward.
