What is the mortgage stress test rate — and how does it affect Windsor buyers?
The stress test is the minimum rate lenders must use to check you can afford a mortgage — it applies to Windsor buyers as it does everywhere in Canada. Here's the current rate and what it means for your borrowing power.
The minimum interest rate banks must use when testing whether you can afford a mortgage. Set by OSFI, Canada's banking regulator. Borrowers must qualify at this rate or their contract rate plus 2%, whichever is higher.
As of July 2026, Windsor's strongest market signal is Hold at 69% — Buy 47%, Hold 69%, Sell 47%.
Market conditions currently favour holding — prices are stable and inventory is balanced.
What this means for you
You must qualify at this rate (or your contract rate + 2%, whichever is higher), so a higher stress test shrinks the mortgage you qualify for — even if your actual rate is lower.
A tougher stress test means fewer qualified buyers, which can soften demand for higher-priced homes.
