OSFI has dropped the mortgage stress test expectation for many uninsured Canadian borrowers who switch lenders at renewal, provided it is a straight switch with no increase to the loan amount or amortization. The change matters because it can make renewal shopping easier for homeowners with at least 20 per cent equity. It does not remove the stress test for new purchases, refinances, HELOCs, or other material credit changes.

What changed in Canada

OSFI’s B-20 guideline sets expectations for federally regulated lenders that underwrite residential mortgages. For uninsured mortgages, OSFI generally requires lenders to use a minimum qualifying rate, commonly called the mortgage stress test, when assessing a borrower’s ability to pay (OSFI, 2026).

The update changes how that expectation applies to a narrow renewal situation. If an uninsured borrower moves the same mortgage balance to another federally regulated lender at renewal, without extending the amortization or borrowing more, the new lender is no longer expected to apply the uninsured minimum qualifying rate.

That is a Canadian-specific issue because most borrowers do not take one 30-year fixed mortgage. They usually have a mortgage term, often 1 to 5 years, and a longer amortization, commonly up to 25 or 30 years. Renewal happens at the end of the term, while amortization is the full payoff schedule.

Who may benefit

This update is most useful if your mortgage is uninsured and your term is ending. An uninsured mortgage usually means you had at least 20 per cent down when you bought, or you otherwise do not have mortgage default insurance attached to the loan.

According to the Financial Consumer Agency of Canada, borrowers should review renewal options before the current term ends and compare the rate, fees, features, and conditions of the new agreement (FCAC, 2026). The OSFI change can make that comparison more practical because a competing lender may be able to assess a straight switch without the added stress test hurdle.

It does not guarantee approval. Lenders can still review income, property, payment history, title details, credit, and their own risk rules.

What still triggers qualification rules

The change is not a full removal of Canada’s mortgage stress test. Expect normal qualification if you are buying a home, refinancing to access equity, increasing the mortgage balance, extending the amortization, adding a HELOC, consolidating debt, or changing the loan in a way that increases lender risk.

Mortgage default insurance also remains a separate issue. CMHC’s home buying resources explain that buyers with smaller down payments may need mortgage loan insurance, subject to eligibility rules and lender requirements (CMHC, 2026).

Why it matters at renewal

The practical effect is bargaining power. A homeowner who can switch lenders more easily may have a stronger reason to compare offers instead of accepting the first renewal letter.

Rates still change frequently. As of June 2026, verify current rates and terms with a licensed mortgage professional before deciding. Fixed and variable mortgage pricing can be influenced by lender funding costs, bond yields, competition, and the Bank of Canada’s policy rate environment (Bank of Canada, 2026).

Look beyond the rate. Ask about discharge fees, legal or title costs, appraisal requirements, prepayment privileges, portability, fixed-rate penalty formulas, and whether the new lender’s terms are more restrictive.

Bottom line

For uninsured Canadian mortgage borrowers, OSFI’s change can make a straight renewal switch easier. If your term is coming up, ask your current lender, competing lenders, or a licensed mortgage broker whether your file qualifies as a stress-test-exempt switch.
