Quick answer: A bank can decline a refinance that would lower your monthly payments because it has to qualify you at a higher rate than you’ll pay: the greater of your contract rate plus 2% or 5.25%. In our example, consolidating debts into a $360,000 mortgage drops an Ottawa household’s debt ratio from 63% to 40%, but at the 7.04% test rate it’s 46%, over a 44% limit. A decline from one bank is not a decline from every lender. Your options depend on how far over you are.
This is one of the most frustrating calls a homeowner can get. The refinance would make your budget easier, the equity is there, and the answer is still no. Here’s why it happens and what you can do next.
Why would a bank decline a refinance that lowers your payment?
Because a refinance is a new mortgage, and the bank must test it at a higher rate. For an uninsured mortgage, a federally regulated lender has to qualify you at the greater of your contract rate plus 2% or 5.25% (OSFI). Your real budget doesn’t come into it. The bank looks at what your payment would be at that higher rate, as a share of your income.
The equity limit is a separate test. You can usually borrow up to 80% of your home’s value (FCAC). Many stress-test declines have plenty of equity. It’s the debt ratio that fails.
What does that look like in numbers?
Here’s an Ottawa household earning $90,000 a year, with $450 a month in property tax and heat and a $450 car payment they’ll keep. They want to refinance to $360,000 to pay off a $290,000 mortgage, $40,000 on credit cards and a $30,000 line of credit. The current mortgage payment of $1,750 is an illustration. Cards and lines of credit are counted at 3% of the balance a month, as lenders count them. The new rate is 5.04%, the best uninsured 5-year fixed we tracked for a refinance up to 80% in Ontario as of October 29, 2026, so the test rate is 7.04%.
| Each month | Before | After, at 5.04% | After, as the bank tests it (7.04%) |
|---|---|---|---|
| Mortgage payment (25 years) | $1,750 | $2,102 | $2,530 |
| Credit cards and line of credit | $2,100 | $0 | $0 |
| Car payment | $450 | $450 | $450 |
| Property tax and heat | $450 | $450 | $450 |
| Total debt ratio | 63.3% | 40.0% | 45.7% |
Counted the lender’s way, their monthly debt payments fall by $1,748. But the test uses the 7.04% payment, and 45.7% is over 44%, the total debt limit CMHC sets for insured mortgages (CMHC) and a common limit for uninsured ones. So the bank says no to the household that would be in the best shape after the refinance.
What can you do after a stress-test decline?
Start with how far over you are. A file at 46% has different options from one at 60%.
- Try another lender. Lenders set their own limits within the rules, especially for borrowers whose credit isn’t in the top tier. A file just outside one bank’s line can sit inside another’s. A broker can run your stress-tested numbers against several lenders before anything is submitted.
- Stretch the amortization. A longer amortization lowers the payment the bank tests. In our example, 30 years instead of 25 brings the tested ratio from 45.7% to 43.7%, just under 44%. It costs more interest over the life of the mortgage, and a lender may still want more room than that.
- Borrow a little less. If you can leave one small debt out, or pay part of it from savings, the tested payment drops.
- Add income. A co-borrower with income, or income the bank didn’t count the first time, changes the ratio directly.
- Look at an Ontario credit union. Credit unions here are regulated by FSRA, not OSFI. FSRA expects them to stress-test and set their own limits (FSRA), so their test may differ from a bank’s.
- Use an alternative lender for a term. A B lender can approve a higher ratio at a higher rate, often for one or two years while you clear the debt and return to a bank. See what a B lender is.
Timing matters too. If your current mortgage is close to maturity, refinancing at renewal avoids a prepayment charge for breaking it early. If you only want to move your existing balance to a better rate, with no new money and no longer amortization, that’s a straight switch, and OSFI doesn’t expect federally regulated lenders to stress-test it at renewal. A switch won’t consolidate your debts, though.
When doesn’t this apply?
If you’re over the limit at every prime lender by a wide margin, another application won’t fix it. The answer is a plan: an alternative lender for a term, paying debts down, or both. If the decline was about equity rather than the debt ratio, because the refinance would take you past 80% of your home’s value, a different lender won’t change that. And consolidating cards into a mortgage only helps if the cards stay paid off. For more on how the test works, see the mortgage stress test for Ontario homebuyers.

Frequently asked questions
Why was my refinance declined if the new payment is lower?
Because the lender has to qualify you at the greater of your contract rate plus 2% or 5.25%, not at the rate you’ll pay. At that higher rate, your debt ratio can go over the lender’s limit even when your real monthly costs fall.
Does the stress test apply to a refinance?
Yes. A refinance is a new mortgage, so federally regulated lenders apply the minimum qualifying rate. A straight switch at renewal, with no new money and no longer amortization, is different: OSFI doesn’t expect lenders to stress-test it.
How much can I borrow when I refinance?
Usually up to 80% of your home’s value, including what you already owe. The lender’s appraisal sets the value.
Will another lender approve my refinance after a bank says no?
Sometimes. Lenders set their own debt ratio limits, so a file just over one lender’s line may fit another’s. If you’re far over at every lender, an alternative lender for a term, or paying debts down first, is the more likely path.
Does a longer amortization help me qualify for a refinance?
Yes. A longer amortization lowers the payment the lender tests, which lowers your debt ratio. In our example, going from 25 to 30 years cut the tested ratio from 45.7% to 43.7%. You pay more interest over the life of the mortgage.
