Calgary Stress Test Calculator
Quick Answer
The OSFI B-20 stress test requires you to qualify at the higher of your contract rate plus 2%, or 5.25%. At a 4.49% contract rate, you must qualify at 6.49%. This reduces your maximum borrowing power by approximately 20% compared to qualifying at your actual rate.

Qualifying Rate (Stress Test)
6.49%
Contract rate + 2% = 6.49%
Floor rate = 5.25%
Higher of the two applies → 6.49%
💡 What This Means for You
Even though your actual rate is 4.49%, the bank qualifies you at 6.49%. This reduces your borrowing power by approximately $88,006 — the stress test is designed to ensure you can handle rate increases.
How It Works
Since 2018, all Canadian mortgage applicants must qualify at a stress-tested rate that is higher than their actual contract rate. The qualifying rate is the greater of:
- Your contract rate + 2%
- The Bank of Canada's qualifying rate floor (currently 5.25%)
This applies to all mortgages — insured, insurable, and uninsured — at federally regulated lenders.

Frequently Asked Questions
What is the mortgage stress test in Canada?
It's a federal regulation requiring all mortgage applicants to prove they can afford payments at a rate higher than their actual contract rate — specifically the greater of contract rate + 2% or 5.25%.
Does the stress test apply to renewals?
If you stay with your current lender, no stress test at renewal. If you switch lenders, you must re-qualify under the stress test.
Can I avoid the stress test?
Only by using a non-federally regulated lender (credit unions in some provinces, private lenders). These may have higher rates and different terms.
