Question 1

What is a mortgage stress test?

Accepted Answer

A mortgage stress test checks whether you can still afford your mortgage payments if interest rates rise. Lenders use it to ensure borrowers won't default during rate hikes.

Question 2

What rate is used in a mortgage stress test?

Accepted Answer

In Canada, lenders test at the higher of the Bank of Canada's benchmark rate (currently 5.25%) or your contract rate plus 2%. US lenders apply similar affordability buffers.

Question 3

Can I fail a mortgage stress test?

Accepted Answer

Yes. If your debt-to-income ratio exceeds lender limits at the stressed rate, you may need to borrow less, make a larger down payment, or choose a longer amortization.

Question 4

Does a stress test affect how much I can borrow?

Accepted Answer

Yes. Stress testing typically reduces the maximum mortgage amount you qualify for by 10–20% compared to qualifying at your actual contract rate.

Question 5

How can I improve my stress test result?

Accepted Answer

You can improve your result by increasing your down payment, reducing existing debts, extending your amortization period, or choosing a lower-rate lender.
