Mortgage Renewal in 2026: Straight Switches, the Stress Test, and Negotiating Your Rate
The qualifying-rate formula itself, the greater of the contract rate plus 2 percentage points or 5.25%, is the stress test explainer. How to compare a fixed offer with a variable offer is the fixed versus variable framework. The cost of leaving before maturity is the IRD penalty guide. All three sit under the Canadian mortgage guide. A renewal is also the moment people start a Smith Manoeuvre, which needs a readvanceable plan and a fresh underwrite.
- OSFI's straight-switch letter is dated November 21, 2024, and the regulator's minimum-qualifying-rate page still described the same exemption in September 2026.
- The exemption is narrow: stand-alone, uninsured, amortizing, not readvanceable, federally regulated lender to federally regulated lender, no longer amortization, and no equity take-out.
- The unpaid balance may be increased by up to $3,000 to cover penalties or fees. That is the letter's allowance for costs. It is not a renovation budget.
- The new lender still underwrites you. OSFI stopped prescribing the qualifying rate for this case. It did not order the lender to approve the file.
- Insured switches, credit-union switches, and any refinance follow their own rules. Do not assume the OSFI letter covers them.
What counts as a straight switch?
| You want to | OSFI's prescribed qualifying rate | What to confirm |
|---|---|---|
| Move an uninsured stand-alone mortgage to another federally regulated lender at renewal. Same balance, aside from up to $3,000 of costs. Same or shorter remaining amortization. | OSFI does not prescribe the minimum qualifying rate. | The new lender still checks income, credit, and the property, and may use its own stressed rate. |
| Borrow more than the $3,000 cost allowance, or lengthen the amortization. | This is a refinance. The prescribed qualifying rate applies at a federally regulated lender. | A penalty can apply if you are not yet at maturity. Price it with the IRD guide before you chase a lower rate. |
| Switch a combined loan plan or a readvanceable mortgage. | The November 2024 letter excludes these. Footnote 1 limits the exemption to stand-alone mortgages outside combined plans, amortizing and not readvanceable. | The readvanceable guide is why a collateral charge is hard to assign. |
| Move to or from a provincially regulated credit union, or from a mortgage finance company. | The letter is aimed at federally regulated institutions. Treat the exemption as unavailable until the new lender says otherwise in writing. | A credit union can still be the right lender. It is a different rule set. |
| Switch an insured mortgage. | Insured qualification is set by the insurer and the Department of Finance, not by OSFI's uninsured letter. | Ask the new lender and the insurer whether they will re-qualify you at the minimum qualifying rate. |

How do you negotiate the renewal?
- Read the renewal letter for an automatic renewal. A lender can roll a closed term into a new term at a rate you did not shop. The date on the letter is the deadline, not a suggestion.
- Write down three facts. Insured or uninsured. Stand-alone or a collateral charge. Balance and remaining amortization. Those facts decide which row of the table you are in.
- Get the current lender's offer in writing, then one other federally regulated offer. Compare rate, term, prepayment privilege, and the penalty method. A cheaper rate with a harsh interest-rate differential is a bet that you will stay the whole term. The penalty guide shows why the discount off the posted rate matters.
- Ask the new lender, in writing, whether they will apply the prescribed qualifying rate. On a qualifying straight switch, OSFI does not require it. The lender can still decline, or still stress the payment under its own policy.
- If you need cash out, stop calling it a renewal. Price the penalty, the new stress test, and the closing costs. Land transfer tax is not charged again on a plain switch of the same property, but a refinance still has legal fees. The cost map is the closing cost guide.
- Decide what the payment is for. A lower payment that you spend is a longer amortization in disguise. A lower payment that you send as a prepayment is the prepayment versus investing choice.
An uninsured borrower owes $420,000 at maturity. A new federally regulated lender will cover a $2,400 discharge and assignment cost by adding it to the balance. The new balance is $422,400. That increase is inside the letter's $3,000 allowance for transaction costs, and equity take-out is still not allowed. The same borrower who wants $25,000 for a kitchen has left the straight switch. The file is a refinance. At a federally regulated lender it is underwritten at the minimum qualifying rate, and the kitchen interest is not deductible. If the kitchen can wait, renew first and price the renovation against cash or against a separate decision.
Some lenders offer to blend the old rate and the new rate instead of charging the interest-rate differential in cash. You still pay the penalty. It is inside the rate. Ask for the penalty in dollars, then decide whether blending or paying it and switching is cheaper over the new term.
Frequently asked questions
Do I still have to pass the stress test to switch lenders in 2026?
On a narrow set of files, OSFI no longer prescribes it. The mortgage has to be uninsured, stand-alone, not a readvanceable combined plan, and moving from one federally regulated lender to another, without a longer amortization and without borrowing more than $3,000 for costs. Everyone else should expect a qualifying-rate test. Even on a straight switch, the new lender underwrites the file and can say no.
Does the straight-switch rule apply to insured mortgages?
OSFI's letter is about uninsured mortgages. Insured mortgages are qualified under rules set for insurers and the Department of Finance. Ask the insurer and the new lender whether a switch at renewal will be re-tested at the greater of the contract rate plus 2% or 5.25%. Do not copy the uninsured exemption across.
Can I roll closing costs into the new mortgage?
The straight-switch letter allows the unpaid balance to rise by up to $3,000 for related costs such as penalties or fees. Anything beyond that, including a renovation or a debt consolidation, is equity take-out. Equity take-out is outside the exemption and is underwritten as a new loan.
What if my mortgage is with a credit union?
OSFI supervises federally regulated institutions. A switch that starts or ends at a provincially regulated credit union is outside the letter as written. You may still get a better rate. Budget for a full application, including the qualifying rate, until the lender confirms otherwise.
Should I break the mortgage before maturity to catch a lower rate?
Only after you have the penalty in dollars from the lender's calculator. On a closed fixed term the charge is usually the higher of three months' interest and an interest-rate differential, and the differential can be several times the interest you think you will save. Run the IRD guide's method, then compare it with the payment difference over the months you have left.
Will renewing into a readvanceable mortgage start the Smith Manoeuvre?
A renewal into a combined plan is a new product, usually a new registration, and it is outside the straight-switch exemption. The revolving limit still has to respect OSFI's 65% loan-to-value cap. Interest is deductible only on the portion whose current use is earning income. Read the readvanceable guide and the Smith Manoeuvre guide before you convert a plain mortgage into a credit line.

A renewal sets the rate. It does not set the tax.
If the renewed debt stays on the home you live in, the interest stays non-deductible. The 2026 tax guide is the filing side of any plan that borrows to invest instead.
