How the 5.25% Qualifying Floor Shapes GTA Buying Power in 2026
When a federally regulated lender approves an uninsured mortgage, the payment it tests is not the payment you will actually make. Under OSFI's B-20 guideline, the borrower has to qualify at the contract rate plus 200 basis points, or 5.25%, whichever is higher. That rule was in place well before 2026, and OSFI's January 2026 review left it unchanged. Anyone reading older commentary about Greater Toronto pricing and timing will find the same test described there, because the test itself has not moved.
What matters is whether the floor or the buffer is the number doing the work on your file.
Where the floor takes over
The two halves of the rule meet at a contract rate of 3.25%. Add 200 basis points to 3.25% and you land exactly on 5.25%. Above that point, the buffer decides your qualifying rate. Below it, the floor does.
Here is some illustrative arithmetic. A borrower offered a 4.00% contract rate qualifies at 6.00%, because the buffer produces the higher figure. A borrower offered 3.00% qualifies at 5.25%, not 5.00%, because the floor sits above the buffer result. If that same borrower later finds a rate a little lower again, their qualifying rate stays at 5.25%. The lower rate reduces the actual monthly payment, but it does nothing for the size of the approval.
That's the part buyers in Vaughan, Richmond Hill and the rest of the GTA tend to miss. When rates ease, people expect their buying power to grow at the same pace. Once contract rates fall under 3.25%, the stress test stops following them down. Qualification is set by the floor, and further rate cuts help with cash flow, not with how much house you can be approved for.
What this means for self-employed borrowers
For business owners, the qualifying rate is only half of the calculation. The other half is the income a lender will accept, and that usually comes from what you reported to CRA, not from what the business brought in.
This is where the floor really shows. If your net income on your T1 has been kept low through legitimate write-offs, the 5.25% test is applied against that lower figure. The floor gives you no extra room, so every dollar of declared income counts for more.
A few practical steps make the conversation with a lender much smoother:
Pull your recent Notices of Assessment and T1 Generals before you start shopping, and confirm there are no balances owing to CRA.
Talk to your accountant before filing, not after, if you expect to buy or refinance in the coming year. How income is reported this tax season affects what you can qualify for next spring.
Ask whether stated-income or alternative lending fits your file if your reported income doesn't reflect what the business can actually support. These options exist, but they come with different pricing and terms, and you should weigh them openly.
For investors, look at how rental income is treated in the debt service ratios, because that treatment varies from lender to lender.
For real estate agents
If you're writing offers for GTA buyers, the pre-approval figure your client brings you was calculated at the qualifying rate, not the rate they'll pay. A buyer who says rates have dropped and asks to stretch the price may not have any more approval room than they did a few months ago. This matters most for self-employed clients, whose files take longer to underwrite and are more sensitive to any change in price or down payment.
Keep financing conditions realistic for these buyers, and encourage them to have their income documents reviewed before they start bidding, not after an offer is accepted. A clean, fully documented file at 5.25% is far more dependable than an approval assumed from a lower headline rate.
For purchases and refinances alike, the useful question in 2026 is not just where rates are heading. It's whether your contract rate sits above or below 3.25%, because that tells you which half of the rule is setting your limit.
