The mortgage stress test qualifying rule remains the greater of your contract rate plus 200 basis points or 5.25%, whichever is higher. In the current rate environment, with contract rates typically above 4%, most borrowers now qualify at their contract rate plus 200 basis points rather than the floor. That changes what matters when you're choosing a mortgage for the Smith Manoeuvre™.
Since June 2021, OSFI's qualification rule has put a floor under stress testing. The rule compared two numbers: your contract rate plus 200 basis points, and a minimum of 5.25%. Whichever was higher became the rate you had to qualify under. A borrower with a contract rate of 2.50% faced a 5.25% test, because the floor pulled the number up. A borrower at 4.00% faced a 6.00% test, because 200 basis points above contract cleared the floor.
The floor remains in place at 5.25%, but in the current rate environment it rarely binds. You typically qualify at your contract rate plus 200 basis points, because rates have risen enough that the buffer now exceeds the floor. If your contract rate is 4.09%, you qualify at 6.09%. If rates fall to 3.00%, you qualify at 5.25%, because the floor pulls the qualifying rate up above the 5.00% that the buffer alone would produce. The test rate moves directly with the contract rate, which means the spread between what you pay and what you qualify at stays constant.
For the Smith Manoeuvre™, that constant spread matters more than the absolute level of rates. The strategy converts mortgage debt into investment debt by redrawing equity as you pay down principal. The readvanceable portion of the credit facility grows each time you make a payment, and the borrowing cost on that portion is deductible if the borrowed funds are used to purchase income-producing investments. The arithmetic works when you can service the full facility at qualification rates while carrying the investment debt at the same time.
When contract rates were very low, the floor limited how much those low rates helped qualification, because the test rate stayed at 5.25% even when the contract rate plus buffer would have been lower. That pinched borrowing capacity. A homeowner with a 2.00% contract rate paid interest on 2.00%, but qualified as if they were paying 5.25%. The gap between the two was wide.
When contract rates are high enough that the buffer exceeds the floor, lower contract rates produce proportionally lower test rates. That narrows the qualification gap and restores some headroom. A borrower at 3.50% qualifies at 5.50% (since 3.50% + 2.00% exceeds the 5.25% floor), so the test rate is slightly higher than the floor in this example. The test rate will fall when contract rates fall, and qualification capacity moves with it.
Variable rates gain an edge here. Fixed rates lock in a term, which locks in your qualification calculation at signing. Variable rates adjust with the lender's prime, and some readvanceable facilities let you reborrow flexibly as your principal balance drops. The combination of falling rates and the constant 200-basis-point spread makes monthly cash flow more predictable. When contract rates are above 3.25%, your test rate falls when your contract rate falls, maintaining a constant 200-basis-point spread, which means your qualification gap stays proportional to your contract rate rather than being pinned to the floor. A readvanceable mortgage combines a declining balance on the amortizing portion with an available line of credit on the investment side. Not all lenders structure these the same way. Some tie readvance limits to scheduled principal reduction. Others allow you to redraw the moment a payment clears. The latter works better for monthly compounding of deductible interest.
Three considerations matter for borrowers looking at the Smith Manoeuvre™ in 2026. First, run the qualification math using the greater of your expected contract rate plus 200 basis points or 5.25%. Second, stress your own cash flow at that test rate while carrying the full investment loan balance, to verify you can manage both. Third, compare variable products on readvance timing and prime-rate adjustment frequency, because when contract rates are high enough that the 200-basis-point buffer exceeds the 5.25% floor, rate drops translate proportionally to lower qualifying rates rather than being absorbed by the floor.
The rule has not changed, but the rate environment has. With contract rates now high enough that the 200-basis-point buffer typically exceeds the 5.25% floor, qualification has become more rate-sensitive than it was when contract rates were very low and the floor was binding, which can make variable products more strategically relevant for borrowers who expect rates to fall.
