Stress Test Update: Self-Employed Borrowers Qualify at the Higher of 5.25% or Contract Rate Plus 2 Points
What changed, and what did not
Two hundred basis points and two percentage points describe the same distance on a rate scale, and that equivalence is the whole of the correction to our earlier article on self-employed borrowers and income discounting. That piece phrased the qualifying rate as the contract rate plus 200 basis points, or 5.25%, whichever is higher. The wording OSFI publishes for uninsured mortgages, as of 2026-09-25, is 5.25% or the contract rate plus 2 percentage points, whichever is higher. CMHC's self-employed fact sheet uses the same phrasing as of 2026-08-15, and Bond Yield Watch lists the same floor and margin as of 2026-09-22.
So the rule itself has not moved. What has changed is the language we used to describe it, which now matches the regulator's, and that is worth fixing because a borrower comparing two documents should not have to wonder whether they describe different tests.
How the formula works in practice
The test produces one number, the qualifying rate, and a lender uses it to calculate the mortgage payment it will measure against your income. Your actual contract rate only matters because it feeds the formula.
Two cases show where the floor takes over. A borrower with a 3.00% contract rate on an uninsured mortgage would have 2 points added for 5.00%, which is below the minimum, so the qualifying rate is 5.25%. A borrower with a 3.99% contract rate would reach 5.99%, which is above the minimum, so the margin decides. These are illustrative rates for the example only.
The floor and the margin therefore do different jobs at different rate levels. At low contract rates, the floor protects the buffer. At higher ones, the 2-point margin does the work and the floor stops mattering. The same formula applies to a refinance, according to OSFI's wording as of 2026-09-25.
Why self-employed borrowers feel it twice
The stress test raises the payment a lender uses. Income documentation determines the other half of the ratio, and for self-employed borrowers that half is often the smaller number.
A salaried borrower's income is read from a letter and a pay stub. A self-employed borrower's income is usually calculated from what the tax filings show, and business deductions that lower taxable income also lower the figure a lender can use. A larger payment divided by a smaller income produces a ratio that tightens from both sides.
The stress test is identical for everyone, which means it is not where self-employed borrowers differ. The difference sits in how each lender interprets the income. Two lenders applying the same qualifying rate can reach different answers because they treat the same tax returns differently.
What to do differently now
Very little changes in the arithmetic, but a few habits are worth tightening.
Use the current wording when you ask a lender or broker for your qualifying rate, so everyone is working from the same formula.
Ask which rate the lender will use for your specific product, then calculate the payment at that rate rather than at the contract rate.
Ask how the lender will arrive at your income, and which documents it will read, before you choose a purchase price.
Compare lenders on income treatment as well as on contract rate, since the qualifying rate is largely fixed by the regulator.
Anyone in Ontario planning a purchase this fall can run these steps in an afternoon, and the answers are better gathered before an offer than after.
What the correction shows
A figure can be right and still be stated in a way that makes readers hesitate. Here, "200 basis points" and "2 percentage points" agree completely, yet one reads like a rate-desk term and the other like a plain sentence. The formula depends on the rate you sign, the floor beneath it, and an income calculation that differs from lender to lender.
