Contract Rate Plus Two Points: The Number That Decides Your Mortgage Approval
A buyer in Abbotsford who signs for a five-year fixed mortgage at 4.5% has to prove to the lender that they could carry the same loan at 6.5%. The 4.5% rate determines the monthly payment. The 6.5% rate determines how much the lender will advance at all.
The rule behind the number
Federally regulated lenders follow the Office of the Superintendent of Financial Institutions under Guideline B-20, which sets the qualifying rate at the contract rate plus 200 basis points, or 5.25%, whichever is higher. Bond Yield Watch lists that formula as current as of September 22, 2026. Insured mortgages, where the down payment is under 20%, use the same formula under Department of Finance rules. A buyer putting 10% down and a buyer putting 25% down both face the same two-point buffer.
The 5.25% floor gets most of the attention because OSFI reviews it publicly. The floor only takes effect when a contract rate falls below 3.25%, though, and through 2026 most mainstream five-year rates have been well above that. In practice, the qualifying rate is determined by the "plus two" half of the formula.
That changes how the test behaves. A floor set by a regulator stays put until the next announcement. A contract rate moves whenever a lender reprices, and fixed-rate pricing follows the five-year Government of Canada bond yield, which has swung noticeably over the past two years. So the bar a household has to clear can shift in a week when no regulation has changed at all.
Where a pre-approval stops protecting you
A pre-approval usually does two things. It holds a rate for a set window, often around 90-120 days, and it gives a rough sense of the maximum loan amount based on the income and debts the borrower reported at the time. Lenders treat the first as a commitment and the second as an estimate.
The estimate stays accurate only while every input stays the same. If the hold expires before an accepted offer, the new contract rate applies, and the qualifying rate rises by the same amount. Choosing a different term, moving to another lender for better pricing, or finding a property that needs a larger loan all produce a new calculation at the rate that day. A half-point rise in a five-year fixed rate becomes a half-point rise in the stress-test rate, and the maximum mortgage shrinks with it.
Abbotsford buyers feel this more than most. Detached homes in the Fraser Valley commonly sell at prices that push households to the top of their debt-service ratios, so the margin is thin. A small change in the qualifying rate can be enough to turn an approval into a request for a larger down payment.
Renewals, switches and the credit union question
Homeowners renewing have more room than they did a few years ago. Since late 2024, an uninsured borrower making a straight switch to a new lender at renewal, with the same balance and amortization, no longer needs to pass the stress test again. Adding funds, extending the amortization or refinancing brings the test back, and it is applied at that day's contract rate plus two.
Provincially regulated credit unions in British Columbia answer to the BC Financial Services Authority, not OSFI. Many follow similar qualifying rules, and some have at times used different criteria on certain products. For a borrower who falls just short at a bank, it may be worth asking a credit union how it qualifies applicants.
A test that measures the future
The two-point buffer was designed as a margin of safety against risks such as higher rates, including at renewal, when the rate may be well above what the borrower signed for. The Bank of Canada has credited it with helping households absorb the rate increases of 2022 and the years after. The same feature that makes it protective also makes it hard to plan around. It assumes rates could rise, so it moves when the market moves. A buyer who expects one fixed approval number is working from a figure that, by design, updates every time lenders reprice.
