A household stress check you can run this week
The most useful thing to do with RBC's forecast is turn it into a number. Ask your lender, or a competing one, for your renewal offer. Then ask what the payment would be at that rate plus one full percentage point. If your household budget absorbs the second number, a gradual climb of the size RBC expects is a manageable problem. If it doesn't, you have learned that months before any hike arrives, with time to adjust.
Here is what one point looks like on common renewal balances with 20 years of amortization remaining:
Rates are illustrative, not quotes. Payments use semi-annual compounding, the standard for Canadian fixed-rate mortgages. Swap in your own balance, amortization and offered rate; the size of the gap between the two payments is the figure that matters.
The regulatory stress test is tougher, and someone else sets it
The plus-one exercise is deliberately gentler than the federal mortgage stress test, and it is worth being precise about who runs that test. It isn't the Bank of Canada. For uninsured mortgages at federally regulated lenders, the Office of the Superintendent of Financial Institutions sets the minimum qualifying rate at the greater of the contract rate plus two percentage points or 5.25%.
For insured mortgages, the federal government applies the same formula, which the Department of Finance and OSFI review each December. Many renewing borrowers will never face that formal test. OSFI does not expect lenders to apply it when an uninsured borrower switches to another federally regulated lender at renewal without adding to the loan or the amortization, and insured borrowers have had the same freedom since December 2024.
