Understand how Canada's mortgage stress test works and how it affects how much home you can afford. Learn the current qualifying rate and strategies to improve your chances.
Canada's mortgage stress test is a qualifying requirement that ensures borrowers can afford their mortgage if interest rates rise. Introduced in 2018, this test requires all uninsured mortgage applicants to prove they can handle payments at a rate higher than their actual contract rate.
The stress test exists to protect both borrowers and the Canadian housing market from becoming overleveraged. It ensures you have a financial cushion if rates increase during your mortgage term.
You must qualify at the higher of: your contract rate + 2%, OR 5.25% (the minimum qualifying rate). This ensures you can handle rate increases.
