Switching Lenders at Renewal Without Re-Passing the Stress Test

For years, the mortgage stress test did something perverse. If you stayed with your existing lender at renewal, no test. If you tried to take the identical mortgage to a competitor offering a better rate, you had to qualify at roughly two percentage points above the rate you were being offered. Plenty of borrowers could not, so they signed whatever their lender put in front of them.

That changed in November 2024. OSFI confirmed that federally regulated lenders no longer need to apply the minimum qualifying rate to a straight switch at renewal. The word doing the work in that sentence is straight.

What counts as a straight switch

A straight switch, sometimes called a transfer, moves the existing mortgage to a new lender without changing its substance. In practice that means all of the following.

• The loan amount stays the same. Not a dollar of new money, and the outstanding balance is what transfers.
• The amortization stays the same or gets shorter. Stretching it out to lower the payment is a change.
• The property is the same, and the borrowers on title are the same.
• The mortgage is at renewal, not mid-term.

Change any of those and you are refinancing, not switching. A refinance is a new mortgage, and the minimum qualifying rate applies: the greater of your contract rate plus two percentage points, or the 5.25% benchmark. The stress test guide explains how that qualifying rate is applied to your debt-service ratios.

What the new lender still checks

Skipping the stress test is not skipping underwriting. Expect all of this.

• Credit. A full credit check and a review of your history since the mortgage was written.
• Income. Pay stubs, a letter of employment, notices of assessment, and business records if you are self-employed.
• The property. An appraisal, often paid for by the new lender as part of a switch package, but confirm it.
• Payment history. Arrears on the existing mortgage will end the conversation quickly.

In other words, a switch is straightforward for a borrower whose circumstances are stable, and harder for someone who changed jobs, went self-employed, or damaged their credit during the term. Check your file first through the credit score guide rather than finding out during the application.

The thing that quietly blocks switches: collateral charges

How your mortgage was registered on title decides how easily it moves. A standard charge is registered for the mortgage amount and can usually be assigned to a new lender cheaply, often with the new lender covering the cost. A collateral charge is registered for a higher amount, frequently up to the property's value, so that the lender can advance more later without new registration.

The convenience has a cost at renewal. Most lenders will not accept an assignment of another lender's collateral charge, so switching means discharging the old registration and registering a new mortgage, with legal fees typically in the several-hundred-dollar range. Some lenders offer a switch package that covers those costs; many do not.

Find out which one you have before you shop. It is on your mortgage documents, and your lawyer or broker can confirm it in a minute.

The timeline that gets you a better rate

1. 120 days out: most lenders will hold a rate for you this far ahead. Get a rate hold from a broker or a competing lender before your own lender's renewal letter arrives.
2. 90 days out: the renewal letter arrives. Treat the rate on it as an opening position, not an offer; the posted renewal rate is often well above what the same lender gives a customer who asks.
3. 60 to 90 days out: collect two or three competing quotes, and ask each about switch fees, appraisal costs, legal costs and the penalty formula for the next term.
4. 45 to 60 days out: take the best external offer back to your current lender. Retention desks match more often than they lose a file.
5. 30 days out: if you are moving, submit the switch. Documents, appraisal and legal work take time, and a late switch can slip past your maturity date into a costly holdover rate.

If you are staying put anyway

Not everyone should move. If your lender matches the market and your mortgage is a collateral charge, staying can be the cheaper answer once legal costs are counted. And if your term still has time to run, the question is not switching at all but whether to blend, which is covered in blend-and-extend versus waiting for renewal.

The mortgage approval guide covers the documents a new lender will ask for, and the mortgage hub has the rest of the home-financing material in one place.

Frequently asked questions

Do I have to pass the stress test to switch lenders at renewal?

Not for a straight switch at a federally regulated lender, following OSFI's November 2024 confirmation. The loan amount and amortization must be unchanged, and individual lenders may still apply their own qualification.

What is the difference between a switch and a refinance?

A switch moves the same balance and amortization to a new lender. A refinance changes the amount, the amortization, or who is on the mortgage, and it is treated as a new mortgage with the stress test applied.

How much does it cost to switch lenders at renewal?

Often little, because the new lender covers the appraisal and assignment costs on a standard charge. A collateral charge usually requires a discharge and new registration, with legal fees typically running into the hundreds.

When should I start shopping for my renewal?

About 120 days before maturity, which is as far ahead as most lenders will hold a rate. Waiting for the renewal letter at 90 days leaves less room to negotiate.

Can I switch lenders if my income has dropped since I bought?

Possibly. The stress test may not apply to a straight switch, but the new lender still verifies income, credit and payment history, so a material change in circumstances can still end the application.
