Short answer: the mortgage stress test checks whether you could still afford your payments if rates were higher. In 2026, lenders regulated by OSFI qualify uninsured borrowers at the greater of your contract rate + 2% or 5.25%. You still pay your actual rate; the higher rate is only used for qualifying. If you are simply switching lenders at renewal without borrowing more, you generally won’t be re-tested.
How the stress test works
When you apply, the lender calculates your housing costs (mortgage payment, property tax, heating and half of condo fees) and your other debts using the qualifying rate, not your real rate. Those costs must fit within the lender’s debt-service limits, usually described as GDS (housing costs ÷ gross income) and TDS (all debts ÷ gross income).
- Qualifying rate: the greater of your contract rate plus 2% or 5.25% (OSFI’s minimum qualifying rate for uninsured mortgages).
- Who it applies to: federally regulated lenders such as banks. Insured mortgages (under 20% down) also face a stress test.
- Who sets other rules: provincially regulated credit unions and private lenders set their own policies.
A simple example
Illustrative only, not a rate offer. If your contract rate were 4.5%, you would qualify at 6.5% (4.5% + 2%), because that is higher than 5.25%. If your contract rate were 3%, you would qualify at 5.25%, because 3% + 2% = 5% is below the floor. The result is the same idea either way: the lender wants room in your budget if rates rise.
When the stress test doesn’t apply
- Renewing with your current lender: no new stress test.
- Straight switch to another lender at renewal: since November 21, 2024, OSFI does not expect lenders to apply the qualifying rate to an uninsured mortgage switched at renewal, as long as you don’t increase the loan amount or amortization. Insured mortgages switching at renewal are treated similarly.
- Refinancing or borrowing more: usually means qualifying again under the stress test.
This matters at renewal time. Because a straight switch generally doesn’t require re-qualifying, many Brampton homeowners can compare offers from other lenders before signing a renewal, instead of accepting the first letter that arrives. See Jatin’s mortgage renewal review.
Ways to improve how you qualify
- Increase your down payment. A smaller mortgage lowers the payment used in the test. See how much down payment you need.
- Pay down or close high-payment debts such as car loans and credit cards, which count against your TDS ratio.
- Document all eligible income. Self-employed borrowers often qualify for less than they earn because income isn’t documented the way lenders need. See self-employed mortgage options.
- Consider a co-borrower whose income and credit can be used.
- Look at amortization. First-time buyers and buyers of new builds can access 30-year amortizations on insured mortgages (since December 15, 2024), which lowers the payment, though you pay more interest over time.
What to do before you shop
Get your numbers reviewed before you make an offer or sign a renewal: your income documents, debts, down payment and the amount you are comfortable paying each month. A pre-approval or a quick review shows how the stress test affects your budget, so there are no surprises later.

Frequently asked questions
What is the mortgage stress test rate in Canada in 2026?
For uninsured mortgages at federally regulated lenders, OSFI’s minimum qualifying rate is the greater of your contract rate plus 2% or 5.25%. Insured mortgages (less than 20% down) use a similar test. You make payments at your actual contract rate; the higher rate is only used to check that you qualify.
Do I have to pass the stress test again when I renew my mortgage?
Not if you renew with your current lender. A straight switch to a new lender at renewal generally doesn’t require a new stress test, as long as the loan amount and amortization aren’t increased. For uninsured mortgages this has applied since November 21, 2024. Adding money or extending the amortization usually means re-qualifying.
Does the stress test apply to private lenders and credit unions?
OSFI’s rule covers federally regulated lenders such as banks. Provincially regulated credit unions and private lenders set their own qualifying policies, which may or may not include a stress test, and their costs and terms can be very different.
How can I qualify for a bigger mortgage under the stress test?
The usual levers are a larger down payment, paying down debts to lower your debt-service ratios, adding a qualified co-borrower, documenting all eligible income, or choosing a longer amortization where eligible. Each option has trade-offs, so it is worth reviewing them before you shop.
