Canadian homeowners with uninsured mortgages generally do not have to pass the OSFI mortgage stress test when making a straight switch to a new federally regulated lender at renewal. In plain English: if the mortgage amount, amortization and borrower stay essentially the same, shopping around at renewal should be easier. The rule does not mean every renewal is stress-test-free, and it does not apply the same way to refinancing or borrowing more.

What changed for renewals?

OSFI’s B-20 mortgage guideline sets expectations for federally regulated financial institutions, including how they assess a borrower’s ability to repay. Under B-20, lenders use debt service ratios and a qualifying rate to test whether a borrower can carry the mortgage under more stressful conditions (OSFI, 2023).

The important renewal update is that a borrower with an uninsured mortgage can make a “straight switch” to another federally regulated lender without being stress tested again. This matters because, before the change, many borrowers could renew with their existing lender without a new stress test, but faced tougher qualification if they tried to move to a competing lender. That reduced their ability to negotiate.

A straight switch usually means:

  • the mortgage is at renewal
  • the borrower is not increasing the principal
  • the remaining amortization is not being extended beyond the existing schedule
  • the property and borrower are not materially changing
  • the new lender is taking over the existing mortgage rather than advancing new money

What still triggers the stress test?

The exception is not a free pass for every mortgage change. If you refinance, add new borrowing, consolidate debt, extend the amortization, change borrowers, or materially restructure the loan, the lender may treat the file as new underwriting.

That distinction is central in Canada. Your mortgage term is the contract period, often one to five years, after which you renew or switch. Your amortization is the full repayment timeline, commonly up to 25 or 30 years depending on the mortgage type and eligibility. A straight switch at the end of the term is different from refinancing the mortgage to access equity or reset the amortization.

The Financial Consumer Agency of Canada explains that mortgages vary by term, amortization, fixed or variable rate, open or closed features, and prepayment rules (FCAC, 2026). Those details still matter when comparing renewal offers.

Why this matters for borrowers

The change should make renewal shopping more competitive. If your current lender offers a weak renewal rate, you may be able to compare offers from banks, credit unions and mortgage brokers without worrying that a new lender will automatically disqualify you under the stress test.

It can also help borrowers whose income, debt load, or household circumstances changed since their original mortgage. They still need to meet the new lender’s documentation and risk requirements, but the qualifying-rate hurdle may not apply if the switch is truly straight.

Rates remain a moving target. The Bank of Canada’s policy rate influences variable-rate mortgages and lender funding costs, although retail mortgage rates also reflect bond yields, lender pricing and borrower risk (Bank of Canada, 2026). As of June 2026, mortgage rates change frequently, so verify current terms with a licensed mortgage professional before deciding.

What to check before switching

Ask the new lender or broker whether your file qualifies as a straight switch. Confirm whether there are legal, discharge, appraisal, title insurance, or administration costs. Check whether your existing mortgage is closed and whether any penalty applies if you move before the renewal date.

Also compare the whole offer, not just the rate. Prepayment privileges, portability, fixed versus variable pricing, payment frequency and the lender’s penalty formula can affect the true cost. A low rate with a harsh interest rate differential penalty may be less flexible if you sell, refinance, or break the mortgage early.

Bottom line

If you are renewing a Canadian uninsured mortgage and only want to move the same mortgage to a new lender, the stress test should generally not block you. If you want to borrow more, extend amortization, add a HELOC, or consolidate debt, expect a fuller review.
