Key takeaways
- For most uninsured mortgages, you must qualify at the greater of your contract rate + 2% or 5.25%.
- The test is about whether you could still afford payments if rates rise. It doesn't change the rate you actually pay.
- At renewal, a straight switch to a new federally regulated lender doesn't require the stress test again.
The "stress test" surprises many buyers. You can afford the payment at the rate you're offered, so why do lenders ask you to qualify at a higher one?
What it is
Canada's banking regulator (OSFI) requires federally regulated lenders to check that uninsured borrowers could still make payments if rates rose or their finances were strained. For uninsured mortgages, the minimum qualifying rate is the greater of:
- your mortgage contract rate plus 2%, or
- 5.25%.
OSFI reviews these figures at least annually. As of its most recent update (January 2026), the 2% buffer and 5.25% floor remain in place. Insured mortgages are tested to a related but different standard set by the mortgage insurers, so your lender can tell you which applies to you.
Examples
| Your contract rate | Qualifying rate |
|---|---|
| 3.00% | 5.25% (the floor is higher than 3% + 2%) |
| 4.50% | 6.50% (rate + 2%) |
| 5.50% | 7.50% (rate + 2%) |
The qualifying rate is used only to assess how much you can borrow. You still make payments at your actual contract rate.
What it means for how much you can borrow
Because lenders calculate your debt ratios at the higher qualifying rate, the stress test reduces the maximum mortgage you can be approved for. It's one reason your pre-approval amount may be lower than you expected.
At renewal
Since November 2024, borrowers with an uninsured mortgage at a federally regulated lender who simply switch lenders at renewal, without increasing the balance or changing the amortization, generally don't need to pass the stress test again. If you want to borrow more or extend the amortization, you'd typically be tested.
What helps you pass
- Lower monthly debts (cards, lines of credit, car loans)
- A larger down payment
- Higher or better-documented income
- A co-applicant with income
Not every lender applies the test the same way (provincially regulated and some alternative lenders may differ), so it's worth discussing your options. A pre-approval shows where you stand.
