Canada’s mortgage stress test in 2026, explained with numbers
How the 5.25% minimum qualifying rate and the 39% and 44% debt limits decide how much you can borrow, with a worked example and the recent rule changes.
Every Canadian buying a home with a mortgage from a federally regulated lender has to pass the stress test. It decides how much you can borrow, and it’s the reason your approval is often lower than the payments you think you could afford. Here’s how it works in 2026 and what it means in dollars.
The rule
Your lender has to check that you could still afford the payments at the minimum qualifying rate: your contract rate plus 2 percentage points, or 5.25%, whichever is higher. The test applies to insured mortgages (less than 20% down) and to uninsured mortgages from banks regulated by OSFI, the federal banking regulator.
At the qualifying rate, your housing costs must stay within two limits:
- Gross debt service (GDS): mortgage payment, property tax, heating and half of any condo fees at most 39% of gross household income.
- Total debt service (TDS): all of that plus car loans, credit cards and other debts at most 44%.
What it does to your budget
Take a household earning C$120,000 with an C$80,000 down payment, C$400 a month of other debt payments and a five-year fixed rate of 4.2% over 25 years.
| Tested at | Largest mortgage | Home price | |
|---|---|---|---|
| With the stress test | 6.20% | C$489,000 | C$569,000 |
| If tested at the contract rate | 4.20% | C$574,000 | C$654,000 |
The stress test cuts the price this household can pay by about C$85,000. The payments are still worked out at 4.2%: about C$2,627 a month on the C$489,000 mortgage. The test only limits how big the loan can be.
When rates are low, the 5.25% floor takes over. With a 3% contract rate, the same household is tested at 5.25%, not 5%, and could buy up to about C$607,000.
Recent changes
- Switching lenders at renewal. Since November 2024 you don’t have to pass the stress test again if you move an uninsured mortgage to a new lender at renewal without borrowing more.
- Bigger insured mortgages. Since December 2024 homes up to C$1.5 million can be bought with less than 20% down. The minimum down payment is 5% of the first C$500,000 and 10% of the rest.
- 30-year amortizations are allowed on insured mortgages for first-time buyers and buyers of new builds, which lowers the qualifying payment.
Ways to qualify for more
- Pay off small debts first. A C$400 car payment counts against TDS every month; clearing it can raise your limit by tens of thousands.
- Put down 20%. You’ll avoid mortgage default insurance, which costs 2.8% to 4% of the loan.
- Look at credit unions. Provincially regulated lenders don’t always have to apply the federal stress test to uninsured mortgages, though many use similar rules.
