Understanding Mortgage Stress Test in Canada
How lenders qualify you above the contract rate.
The stress test makes sure you could still afford payments if rates went up. It applies to all federally regulated mortgages in Canada.
The qualifying rate
You must qualify at the greater of (a) your contract rate + 2%, or (b) the Bank of Canada's benchmark rate of 5.25%.
Why it exists
Introduced by OSFI to reduce the risk of widespread defaults if rates rise sharply. It effectively caps how much you can borrow.
Example
Contract rate 4.5%. Stress test rate = max(4.5% + 2%, 5.25%) = 6.5%. Your debt ratios are calculated using 6.5%, not 4.5%.
Impact on borrowing power
On the same income, the stress test typically reduces the maximum mortgage by around 20%. Strategies: pay down debt, increase down payment, add a co-signer, or extend amortization to 30 years if eligible.
Key takeaways
- Applies to bank mortgages — credit-union rules vary
- Uses qualifying rate, not contract rate
- Reduces max borrowing by ~20%
- Renewing with the SAME lender may skip the test; switching lenders may not
