Contract Rate Plus 2%: Why Your Qualifying Window Is Shorter Than It Looks
A buyer quoted 4.25% gets approved as though the rate were 6.25%. A buyer quoted 2.99% gets approved as though it were 5.25%, which is exactly where a buyer quoted 3.25% lands too. That is the stress test as it stands in October 2026. Under OSFI's Guideline B-20, and under the federal rules for insured mortgages, you qualify at your contract rate plus 2 percentage points or at 5.25%, whichever is higher.
Most people read that formula as a limit on how much they can borrow. It also controls when you can borrow it. Above a 3.25% contract rate, every rate increase flows straight into a smaller approval. Below 3.25%, further drops do nothing for your approval at all. Whether you're months from buying, holding a rate offer, or a year or two from renewal, the number to watch is how long your qualifying amount will hold up.
Above 3.25%, every quarter point moves your approval
Here's an illustrative example. Say a household's income and debts leave room for $3,000 a month in qualifying mortgage payments, on a 25-year amortization.
Qualifying at 5.25% (any contract rate of 3.25% or less), that payment supports roughly $503,000.
Qualifying at 6.25% (a 4.25% contract rate), it supports roughly $458,000.
One percentage point costs about $45,000 of approval, close to 9%. A first-time buyer using the 30-year insured amortization available since December 15, 2024 sees larger dollar figures, but rates move them the same way. If your quoted rate sits above 3.25%, a market bump during your house hunt shrinks your budget right away.
The floor makes waiting a one-sided bet
Plenty of buyers in the Cowichan Valley are waiting for rates to come down. If your quote is already near 3.25%, a lower rate would trim your payment but leave your approval where it is, because the 5.25% floor is doing the qualifying.
