If you’re comparing mortgages, you’ll notice two different numbers: the payment you’ll actually make and the higher payment you must qualify for. That gap is the stress test, and it is the reason some buyers are approved for less than they expected.
The rule, in plain language
Lenders qualify you at the higher of:
- your contract rate plus 2%, or
- the Bank of Canada benchmark rate.
So if your contract rate is 5%, you will qualify at 7% (unless the benchmark is higher).
Why your qualifying payment looks “too high”
It’s not a mistake. The stress test is a guardrail against rate increases. It answers one question: Could you still afford this mortgage if rates jumped?
That’s why your qualifying payment can be hundreds of dollars higher than your real payment.
When the benchmark matters (and when it doesn’t)
- If your contract rate is already high, the benchmark may not change anything.
- If your rate is low, the contract + 2% rule usually drives the qualifying rate.
Either way, the qualifying rate is the number that decides approval.
How to use the stress‑test payment
Use it as a capacity check, not your budget:
- If the stress‑test payment feels tight today, a rate increase later could be painful.
- If it feels manageable, you have more buffer if rates move.
The stress‑test payment isn’t what you will pay. It’s what you must prove you could pay.
A practical checklist before you commit
- Confirm the qualifying rate your lender is using.
- Compare offers using the same purchase price, down payment, and amortization.
- Don’t assume approval equals comfort — test your cash flow against the qualifying payment.
The bottom line
The stress test doesn’t change your contract payment, but it does change how much you can borrow. Use it as a reality check, and build your budget around what you can sustain — not just what you can qualify for.
