Does the stress test mean I pay a higher interest rate?

No. You still pay your contract rate. The stress test only uses a higher qualifying rate to calculate how large a mortgage you can be approved for.

What is the current stress test rate?

You must qualify at the greater of your contract rate plus 2 percentage points or the minimum qualifying rate of 5.25%.

Does the stress test apply when I renew?

If you renew with your existing federally regulated lender, you may not have to re-pass the stress test. But switching to a new lender at renewal generally means qualifying under the test again.

What is Stress Test?

The mortgage stress test is a Canadian qualifying rule that checks whether you could still afford your mortgage if rates rose. You must qualify at the greater of your contract rate plus 2% or a minimum qualifying rate of 5.25%. It does not change the rate you actually pay; it only changes how large a mortgage you can be approved for.

Also known as: Mortgage stress test, Qualifying rate

Key points

Qualify at the greater of your contract rate plus 2% or 5.25%.
Applies to most federally regulated lenders for insured and uninsured mortgages.
Does not change your actual contract rate, only your maximum approval amount.
Builds a buffer so you can manage payments if rates rise at renewal.
Lower other debt and a stronger application can offset its impact on borrowing power.

Stress Test explained

Under the federal stress test, lenders calculate your debt service ratios using a higher qualifying rate rather than the rate written into your mortgage. The qualifying rate is the greater of the Bank of Canada minimum of 5.25% or your contract rate plus 2 percentage points. The rule applies to most federally regulated lenders for both insured and uninsured mortgages.

The goal is to build a cushion so borrowers are not caught out if interest rates climb at renewal or on a variable-rate mortgage. Because the test uses a higher rate, it reduces the maximum mortgage you qualify for compared with qualifying at your actual rate, which means the amount you can borrow may be lower than your monthly budget alone would suggest.

What a Stress Test is for

The stress test exists to protect borrowers and the broader financial system from the risk of homeowners overextending at temporarily low rates. By proving affordability at a buffer above the contract rate, borrowers are more likely to manage payments if rates rise by renewal time.

How it can help you

Understanding the stress test helps you set a realistic budget before you shop, so you are not surprised by a lower approval amount. It also rewards strengthening your file, paying down other debts, or finding a sharper rate.

When it comes up

A buyer is offered a 5-year fixed at 4.5%. The lender does not qualify them at 4.5%; instead it uses 6.5% (contract rate plus 2%) because that is higher than 5.25%. Their approval amount is based on payments at 6.5%, leaving a buffer if rates climb.

Example: How the qualifying rate is set

Suppose your contract rate is 4.7%. The stress test compares two numbers: 5.25% (the floor) and 4.7% + 2% = 6.7%. The greater of the two is 6.7%, so you must qualify at 6.7%.

Now suppose your contract rate is only 2.9%. The two numbers are 5.25% and 2.9% + 2% = 4.9%. Here 5.25% is greater, so you qualify at 5.25%. In both cases the rate you actually pay is unchanged; only your approval amount is affected.
