Canadian homeowners with uninsured mortgages may have more room to shop at renewal because OSFI no longer expects federally regulated lenders to apply the mortgage stress test to a straight switch. In plain terms, if you move the same mortgage balance to a new lender at renewal and do not increase the amortization, the new lender may not need to qualify you under the minimum qualifying rate. This does not remove the stress test for new purchases, refinances, added borrowing, or many other material changes.

What changed for mortgage switches in Canada

OSFI’s B-20 guideline sets mortgage underwriting expectations for federally regulated lenders, including banks (OSFI, 2026). The important change for borrowers is narrow: a “straight switch” of an uninsured mortgage at renewal can be treated differently from a new mortgage application.

A straight switch generally means:

  • the mortgage is at the end of its term
  • the borrower is moving to a new lender
  • the loan amount is not being increased
  • the remaining amortization is not being extended
  • the property and borrower are not materially changing the risk profile

This matters because Canada does not usually have the US-style 30-year fixed mortgage. Canadian borrowers typically choose a mortgage term, often one to five years, within a longer amortization, commonly 25 or 30 years. When the term ends, the borrower renews, renegotiates, or switches lenders.

Why this is useful

Before this change, some uninsured borrowers could feel locked in with their current lender at renewal. Even if another lender offered a better rate, the borrower might have had to pass the stress test again to switch. That could be difficult if income had changed, debts had risen, or rates were higher than when the mortgage was first approved.

The Financial Consumer Agency of Canada explains that mortgage renewals are a chance to compare rates, payment options, and terms before accepting a lender’s offer (FCAC, 2026). This OSFI change makes that comparison more practical for some borrowers because the stress test is less likely to block a simple move to a competing lender.

When the stress test can still apply

The change does not mean the Canadian mortgage stress test is gone. It can still apply when you buy a home, refinance, increase the mortgage balance, extend the amortization, add a borrower, remove a borrower, or make another change that causes the lender to underwrite the file as new credit.

It can also matter whether your mortgage is insured or uninsured, whether the lender is federally regulated, and whether the transaction fits the lender’s definition of a straight switch. Mortgage default insurance, provincial and territorial rules, and lender policies can affect how your file is handled.

The Bank of Canada’s policy interest rate also remains relevant because it influences variable mortgage rates, lender funding costs, and broader rate conditions (Bank of Canada, 2026). As of June 2026, mortgage rates change frequently, so verify current terms with a licensed mortgage professional before deciding.

What borrowers should do at renewal

Do not accept a renewal offer without comparing it. Ask your current lender for its best available rate, then compare offers from other lenders or a licensed mortgage broker. Confirm whether your file qualifies as a straight switch and whether the new lender will require a full stress test.

Also check the details beyond the rate: prepayment privileges, portability, penalties, payment frequency, fixed versus variable terms, and whether the mortgage is open or closed. A lower rate can be less useful if the penalty terms are poor or if the product limits future flexibility.

Bottom line

OSFI’s stress test change on mortgage switches is good news for many Canadian homeowners renewing an uninsured mortgage. It may make it easier to leave an uncompetitive lender without requalifying under the full stress test, as long as the switch is simple and the mortgage amount and amortization are not increased.
