Straight switches to a new lender at renewal, with no new money, no longer need the stress test for uninsured mortgages (since November 21, 2024).

How it's worked out

Federally regulated lenders (OSFI Guideline B-20) and every insured mortgage use the same minimum qualifying rate: the greater of 5.25% and the contract rate plus two percentage points.

The calculator works out the monthly payment at that rate over your amortization, adds property tax and heating, and asks what income keeps that total at 39% of gross monthly income. That's the highest GDS insured lenders accept.

Other debts count against the 44% TDS limit, so real borrowers usually need more income than this. Use the affordability calculator to include them.
