If you’ve applied for a mortgage in Canada, you’ve likely wondered what the Mortgage Stress Test is — but few buyers truly understand its purpose. Introduced to ensure Canadians can handle potential rate increases, it affects how much you can borrow, regardless of your actual rate.
At Sunlite Mortgage, we make this rule clear, so you know exactly how it impacts your budget and how to navigate it successfully.
The stress test is a federal qualification rule requiring lenders to calculate your affordability as if your rate were higher than what you’ll actually pay.
As of 2025, the minimum qualifying rate is the greater of:
This ensures that if rates rise in the future, you’ll still be able to manage your payments.
The qualifying rate is the interest rate used by lenders to test your ability to afford your mortgage. It’s higher than your actual rate, ensuring you can handle future increases.
Because you’re approved based on a higher “test” rate, your maximum mortgage amount may be lower than expected.
For example:
While it can be frustrating for buyers, it’s designed to protect Canadians long-term.
A buyer in Ottawa improved their credit score by 30 points and paid off a small car loan before applying. Their pre-approval rose from $540,000 to $610,000 – all while staying compliant with the stress test.
We calculate qualification limits using the latest rules from the Office of the Superintendent of Financial Institutions (OSFI) and the Bank of Canada. You’ll always know where you stand — and what steps to take next.
