Switching lenders at renewal used to come with a catch: you could find a better rate, then fail the stress test at the new lender and feel stuck with the one you had. That has changed, but not for everyone. Many online explanations skip the conditions, and some still say the stress test always applies.
With the Bank of Canada raising its policy rate to 2.5% on October 28, 2026, the first increase since 2023, more Ontario homeowners are looking hard at their renewal options. Here is what the rule actually says, who it helps, and what can knock you out of it.
One pattern I’m seeing right now is homeowners extending their amortization again to bring their payments down. That can make a higher rate easier to carry, but it comes with a catch if you also want to switch lenders, because a longer amortization can take you out of the rules below.
The Short Answer
You generally won’t face the federal minimum qualifying rate if all of the following are true:
- You are moving at renewal from one federally regulated lender to another
- You are not increasing your loan amount, beyond up to $3,000 for costs such as fees
- You are not extending your remaining amortization
- Your mortgage is a stand-alone, amortizing mortgage, not a readvanceable product tied to a line of credit
If you meet those conditions, the new lender is no longer required to test you at the prescribed rate. That does not mean approval is automatic, which we’ll get to below.
What the Stress Test Normally Requires
For uninsured mortgages, federally regulated lenders normally qualify you at the greater of your contract rate plus 2% or 5.25%. This is the minimum qualifying rate, usually called the stress test.
Staying with your current lender at renewal has never required you to pass it. That gap created a real problem. A homeowner whose income had dipped, or whose debts had grown, could be stuck with an uncompetitive renewal offer because no other lender could approve them at the higher qualifying rate.
The Two Straight Switch Rules
A “straight switch” means moving your existing mortgage to a new lender at renewal without changing the terms that matter: the loan amount and the amortization. Two separate rules apply, depending on your mortgage.
| Uninsured straight switch | Low-ratio insured straight switch | |
|---|---|---|
| Effective | November 21, 2024 | Insurance applications from December 16, 2024 |
| Set by | OSFI | Department of Finance |
| Loan-to-value | Not the deciding factor | Up to 80% |
| Balance increase | Up to $3,000 for costs | Up to $3,000 for costs |
| Amortization | No increase | Existing schedule must be kept |
| Equity take-out | Not allowed | Not allowed |
You can read the conditions directly in OSFI’s notice on uninsured straight switches and the Department of Finance backgrounder. Mortgages with high-ratio default insurance have their own insurer rules, so confirm those with the new lender before assuming anything.
What Disqualifies You From a Straight Switch
This is where homeowners get caught. Any of these usually takes you out of the exemption:
- Adding to your mortgage. Rolling in a car loan, a renovation or credit card debt makes it a refinance, not a switch.
- Extending your amortization. If you have 22 years left, moving to 25 years to lower the payment does not qualify.
- Having a readvanceable mortgage. Combined plans that pair a mortgage with a home equity line of credit are excluded. Many homeowners have one of these without realizing it, so check your paperwork.
- Moving to or from a lender that isn’t federally regulated. The uninsured exemption covers switches between federally regulated institutions. Credit unions and private lenders set their own qualifying policies, which can sometimes help, but they fall outside this specific rule.
No Stress Test Doesn’t Mean Automatic Approval
OSFI is clear that the new lender should still assess a switch like any other new mortgage. Expect the lender to review:
- Your current income and how you document it
- Your credit history and existing debts
- The property’s value, which may need an appraisal
- Your ability to carry the payment under its own underwriting policy
If you are self-employed, this review matters most. Your income may have been fine at your last approval and look different on your latest tax return. A lender can still decline you even when the stress test is off the table.
What a Better Rate Could Be Worth
Here is a hypothetical example. These are not current rates or a rate offer.
Say you owe $480,000 with 22 years left. Your bank offers 4.69%, and another lender offers 4.29% on the same five-year term.
| Bank’s offer | Switching lenders | |
|---|---|---|
| Rate (hypothetical) | 4.69% | 4.29% |
| Monthly payment | $2,905.90 | $2,802.31 |
| Interest over 5 years | $103,728 | $94,645 |
| Balance after 5 years | $409,374 | $406,507 |
That is about $104 less each month, roughly $9,100 less interest over the term, and a lower balance at the end. Without the exemption, the new lender would have needed to qualify this borrower at 6.29%, which works out to a payment of about $3,338 for qualifying purposes.
You can run your own numbers with the mortgage renewal calculator.
How to Switch Lenders Step by Step
- Start about 120 days before maturity. Rate holds commonly last 120 days, so starting then can protect you if rates rise. Confirm how long your hold lasts.
- Confirm your mortgage type. Check your last statement for your balance, remaining amortization, maturity date, and whether it is insured or readvanceable.
- Compare the full offer, not just the rate. Look at prepayment privileges, portability and how the penalty is calculated.
- Ask what the switch costs. Appraisal, legal and discharge fees can apply, and some lenders cover some of them. Your $3,000 allowance only helps if costs are rolled in correctly.
- Time it to your maturity date. Leaving before maturity can trigger a prepayment penalty. Switching at maturity normally avoids one.
The most common delay I see is paperwork. When documents take too long to come in, the whole switch slows down, and your maturity date doesn’t move. Have your documents ready before you start.
Should You Wait After the Rate Increase?
Nobody can reliably predict the next move. The Bank of Canada has said further increases could be needed, while adding that it will proceed carefully. Its next decision is December 9, 2026. Fixed mortgage rates also respond to bond yields rather than following the policy rate directly.
The practical point: if your renewal is within the next few months, getting your options in place now costs little. Our mortgage renewal guide walks through the broader decision, and if the letter has already arrived, read why you shouldn’t sign your bank’s offer yet.
Frequently Asked Questions
Do I have to pass the stress test to switch lenders at renewal?
Not if you meet the straight switch conditions above. If you add money, extend your amortization or have an excluded product, expect to be qualified under the normal rules.
Can I add my renovation costs while switching?
Not as a straight switch. Beyond the $3,000 allowance for costs, adding funds makes it a refinance.
Does this apply if I switch to a credit union?
The uninsured exemption is for moves between federally regulated institutions. A credit union may have its own policy, so ask directly.
