The Mortgage Stress
Test, Explained

It isn't as scary as it sounds.

Since 2018, every mortgage applicant in Canada gets stress-tested. Here's what the test actually does, why it exists, and exactly how to run your own numbers before you apply.

Benchmark rate 5.25% min Or Contract rate + 2% Applies to All federal lenders Introduced January 2018 At renewal Generally exempt

How the math actually works.

Four steps. Plain language. No acronyms without definitions.

01. Pick the qualifying rate

You qualify at whichever is higher: the Bank of Canada's minimum qualifying rate (currently 5.25%) OR your actual contract rate + 2%.

02. Calculate your maximum mortgage at that rate

Your lender runs your income and debts through GDS and TDS ratio limits at the stress test rate - not your actual rate.

03. That maximum is your approval ceiling

Your pre-approval and final approval are both based on the stress-tested number. You can always buy less - but you can't buy more.

04. Your actual payment uses your real rate

Once approved, your monthly payment is calculated at your real contract rate - not the stress test rate.

What it means in practice.

The stress test reduces your maximum mortgage - but your actual payment is based on your real rate, not the qualifying rate.

How I approach this

“The stress test was designed to make sure you can still afford your payment if rates rise. It's frustrating when you're close to the limit - but it's done a real job of keeping people from over-buying.”
- Jeremy LaHaie

When the stress test was introduced in 2018, a lot of people in the mortgage world were frustrated - it reduced what buyers could qualify for, sometimes by $50,000 or more.

But the intent was sound: if rates rose significantly, buyers who qualified at rock-bottom rates might struggle with the payment. The stress test was a buffer.

In practice, your pre-approval number will be lower than it would be without the test, but it's a more honest number.

If the stress test is keeping you from the home you want, I'll tell you the exact path to close the gap: how much more down payment helps, which debts to pay down first, and whether a slightly lower purchase price changes the picture.

Stress test FAQs.

What's the current stress test rate?

Whichever is higher: the Bank of Canada's minimum qualifying rate (currently 5.25%) or your actual contract rate + 2%.

Does the stress test apply if I put 20% or more down?

Yes. It applies to all insured and uninsured mortgages at federally regulated lenders, regardless of down payment size.

How much does it reduce my purchasing power?

Roughly 18–22% compared to qualifying at your actual contract rate.

Can I get around the stress test?

Not at a federally regulated lender. Private lenders don't apply it, but the rate trade-off is significant.

Does the stress test apply at renewal?

Generally no if you stay with your existing lender. If you switch lenders at renewal, the new lender will stress test you.

What if I'm close to the stress test limit?

Increase your down payment, pay down existing debts, extend your amortization, or target a lower purchase price.
