Start by asking your current lender whether an internal conversion is available. Get the offered fixed rate and term, effective date, conversion fee, minimum-term rule and any other conditions in writing.
An internal conversion is different from breaking the mortgage, transferring it to another lender or refinancing. Those alternatives can trigger prepayment penalties, discharge costs, appraisal fees and a new qualification review. Compare the total cost and payment—not just the advertised rate—against converting, blending and extending, or waiting until renewal.

What “switching” can mean
Borrowers use “switch” for several different transactions. Identify which one you are considering before asking for a quote:
- Internal conversion: You keep the mortgage with the same lender and exercise a contractual feature to change from variable to fixed during the existing term.
- Blend-and-extend or early renewal: The lender replaces the remaining term with a new one and calculates a blended rate. This is not the same as simply exercising a conversion clause.
- Break and transfer: You pay out the current mortgage and move it to another lender. A prepayment charge and discharge or setup costs may apply.
- Refinance: You replace the mortgage, potentially change the balance or amortization, and qualify under the new lender’s rules.
The steps and costs below are written for Canada. Provincial rules and lender contracts differ, and a lender’s conversion feature is not a market-wide entitlement.

Can I switch from a variable-rate mortgage to a fixed rate?
Check the mortgage commitment, standard charge terms and any renewal or amendment documents for words such as “convertible,” “conversion,” “fixed-rate option” or “change of interest-rate type.” The Financial Consumer Agency of Canada (FCAC) says some lenders allow a variable mortgage to be switched to fixed during rising or falling rates, but the feature can carry fees and conditions, and the new fixed rate may be higher than the variable rate you have paid.
Confirm how your variable mortgage payment works:
- With an adjustable-payment variable mortgage, the payment normally changes when the lender’s prime rate changes.
- With a fixed-payment variable mortgage, the payment may stay level while the interest portion changes. If rates rise enough, less of each payment goes to principal. A lender trigger point can require a higher payment, a lump sum or another action, and in some contracts the balance can grow.
Ask the lender to identify the remaining term, amortization, current balance, payment frequency, prepayment privileges and any trigger-point language. If a clause is unclear, request a written explanation rather than assuming the mortgage is convertible.
How to change your mortgage rate from variable to fixed
- Collect your contract details. Record the lender, mortgage type (open or closed), current balance, payment, remaining term, amortization and renewal date. Note whether the rate is fixed-payment or adjustable-payment variable.
- Ask for an internal-conversion quote. Request the fixed rate available today, every eligible term, the exact effective date, any conversion fee, the minimum term, and whether the conversion changes your payment schedule or amortization.
- Ask about qualification and restrictions. Find out whether you must submit a new application, pass a stress test, provide updated income documents or keep the mortgage balance unchanged. Ask how soon you may make lump-sum payments, refinance or convert again.
- Separate conversion from a payout. Ask the lender to state explicitly whether the proposal is an amendment to the existing mortgage or a discharge and replacement. If it involves paying out the loan, obtain a dated written penalty and fee estimate.
- Price the alternatives. Obtain figures for an internal conversion, blend-and-extend or early renewal, and keeping the variable mortgage to renewal. If you are considering another lender, request the complete payout, transfer and new-mortgage costs before comparing rates.
- Compare personalized outcomes. For each option, calculate the payment and total interest over the same period, principal repaid, next term-end date, prepayment flexibility and cost of selling or refinancing early.
- Confirm implementation in writing. Before the change takes effect, verify the fixed rate, term, balance, payment amount and frequency, effective date, fee, and any revised prepayment privileges in the lender’s documents. Keep the confirmation and the final statement.
Questions to put to the lender
A general rate quote is not enough. Ask for answers that apply to your account and request them by email or in the amendment documents:
- Is my exact mortgage convertible, and until what date can I exercise the feature?
- What fixed rates and terms are available today, and are they the lender’s posted, discounted or special rates?
- Does the new term have to be at least a particular length, or no shorter than the remaining term?
- Is there a conversion, administration or registration fee? Is it charged immediately or added to the balance?
- Will my payment amount, frequency, amortization or payment date change?
- Do I need a new application, income verification, appraisal or qualification test?
- Will existing privileges—annual lump sums, payment increases, portability and refinancing—remain unchanged?
- How soon can I convert again, renew, sell or make a large prepayment after accepting the fixed term?
- What is the lender’s written penalty if I break the new fixed mortgage before maturity?
Ask the representative to identify the document that controls each answer. A verbal promise or an online advertisement may not match the signed contract.
Four ways to respond to a rising-rate concern
| Option | Questions to ask | What to compare |
|---|---|---|
| Convert with current lender | Is conversion allowed? What rate, term, fee and conditions apply? | Payment certainty, conversion cost, next term-end and future prepayment flexibility |
| Blend-and-extend or early renewal | Is it available? How is the blended rate calculated? Are administration fees charged? | Blended rate, new term, fees, payment and interest over the new term |
| Keep the variable mortgage to renewal | How will payments and principal change if rates move? When can you renegotiate? | Budget tolerance, payment structure, trigger point and possible future rates |
| Break, transfer or refinance | What is the written penalty and complete discharge, setup and appraisal cost? Will I qualify? | Break-even time, rate and term, all fees, qualification risk and flexibility |
No choice is automatically cheaper or safer. Compare offers over equivalent time horizons using the lender’s actual numbers, not only a headline rate.
Costs and penalties to check
Internal conversion costs
A conversion may be free, or the lender may charge an administration fee or impose a minimum fixed term. FCAC and Quebec’s Autorité des marchés financiers (AMF) both caution that conditions vary. The fixed rate is the lender’s offer on the conversion date; it is not necessarily the rate you see in an advertisement or the rate available at renewal.

Breaking or transferring a closed mortgage
Paying out a closed mortgage before the term ends can result in a prepayment charge. Depending on the contract, the charge may be a set number of months’ interest or an interest-rate differential (IRD), often alongside administration, appraisal, reinvestment or discharge fees. The FCAC prepayment-rights guidance applies to federally regulated institutions such as banks and federal credit unions; other institutions and provincial rules can differ.
Ask for a written payout statement dated for the day you might close. The balance, accrued interest, lender rate and remaining term can change, so an estimate made weeks earlier may no longer be accurate. Confirm whether unused prepayment privileges, a lump-sum payment or an assumable mortgage can reduce the amount owing before a payout.
What Canadian mortgage data does—and does not—tell you
A 2026 Bank of Canada staff working paper reports that full prepayment and refinancing outside renewal periods are rare in Canada. It describes annual lump-sum privileges commonly limited to 10%–20% of the initial balance, three months of interest as a variable-mortgage prepayment penalty in the contracts it discusses, and IRD calculations for some fixed-rate breaks when rates fall. These are descriptive findings, not a quote for your mortgage; lender formulas differ. Use your contract and a lender-generated estimate (Bank of Canada Staff Working Paper 2026-2).
Blend-and-extend: an early-renewal comparison
Blend-and-extend can let you renew early without the usual prepayment penalty, although an administration fee may apply. The lender combines the rate on your remaining term with its current rate for the new term. Ask for the exact calculation and whether the new term starts immediately.
FCAC illustrates the method with a simplified example: a $200,000 balance at 5.5% with 24 months remaining, combined with a 4% rate for a new five-year term, produces an illustrative 4.6% blended rate. The FCAC example is not a quote or a universal formula. Your lender may use different balances, weighting, rounding or fees.
A lender’s conversion rule is not a universal rule
TD Canada’s published variable-mortgage information says its customers may switch at current mortgage rates, subject to a selected term of at least the lesser of three years or the remaining original term. That is a lender-specific condition for the cited product, not a rule that applies to every Canadian mortgage. Ask your own lender for its current written terms.
In Quebec, AMF’s mortgage-features guidance distinguishes open, closed and convertible mortgages and explains that the lender’s offered rate and conditions govern a variable-to-fixed change. Elsewhere, provincial consumer rules and the lender’s contract may produce different results.
How payment design affects the decision
Compare the principal balance as well as the payment. A fixed-rate payment is generally predictable for the selected term, but the amount depends on the offered rate, amortization and payment frequency. A variable mortgage with adjustable payments passes rate changes through to your budget. A fixed-payment variable mortgage can hide the effect temporarily: when interest rises, more of the same payment goes to interest and less to principal.
Ask whether your account is near its trigger point. Depending on the contract, reaching it can cause an immediate payment reset, a required lump sum, an amortization change or a balance that grows instead of shrinking. Get the lender’s projected balance and payment at several rate levels. This makes the risk concrete and lets you compare it with the fixed conversion payment.

Compare the outcome, not only the rate
Build a side-by-side worksheet for the same comparison period—for example, the time until the earliest date you could next change the mortgage. Include:
- Payment: amount, frequency and whether it can change.
- Interest: projected interest paid during the comparison period using the lender’s amortization schedule.
- Principal: balance at the end of the period and principal repaid.
- Term and renewal: the next renewal date and the rate risk you retain after the comparison period.
- Flexibility: annual lump-sum limit, payment-increase privilege, portability, refinancing rules and cost to break the new fixed term.
- One-time costs: conversion, administration, appraisal, legal, discharge, transfer and registration charges.
- Exit scenarios: what happens if you sell, refinance, make a large prepayment or move before the new term ends.
For a transfer, divide the total switching cost by the expected monthly saving to estimate a simple break-even period. Then test whether you would still break even if the outside lender’s rate changes before closing, the appraisal is lower than expected or qualification rules prevent approval. A lower rate that never recovers its penalty and setup costs is not a saving.
Timing, documents and implementation
Ask when the quoted rate expires and whether the lender can hold it until the conversion date. Do not assume that a rate discussed by phone is locked. Confirm the effective date, because interest can accrue under the variable formula until the amendment is actually registered or processed. Before authorizing the change, read the rate, term, balance, payment schedule, fee disclosure and prepayment section. Afterward, check the first statement to ensure the new payment and principal allocation match the documents.
Rank #4
If you are transferring or refinancing, allow time for an appraisal, income verification, lawyer or notary work, discharge instructions and registration. A lower rate at another institution is useful only if approval and closing occur before the current term’s obligations or the quoted offer expires.

Fixing the rate can make a payment predictable for the chosen term, which may help a household with little room in its monthly budget. It also removes the risk that a variable rate will rise during that term. In exchange, the fixed offer may be higher than the variable rate you have been paying, and breaking the new fixed mortgage can be expensive if rates fall or your plans change.
Keeping the variable mortgage preserves the possibility of benefiting from lower rates and may offer a less costly exit, but the payment or principal allocation can change. A blend-and-extend may reduce an immediate penalty while committing you to a new term and blended rate. The right choice depends on cash-flow capacity, expected time in the home, tolerance for rate changes and the contract’s flexibility.
Common mistakes and how to correct them
- Assuming every variable mortgage converts: Ask for the clause and written eligibility conditions.
- Comparing advertised rates only: Request personalized payment, balance and fee figures for the same term.
- Calling every switch a conversion: Confirm whether you are amending the mortgage or discharging it.
- Ignoring the next exit: Read the new fixed mortgage’s prepayment and portability provisions before accepting.
- Using a penalty estimate as a final number: Obtain a dated payout statement and ask how long it remains valid.
- Overlooking payment structure: Check whether a fixed-payment variable mortgage is approaching its trigger point and what action the lender requires.
- Waiting until the effective date to read documents: Review the rate, term, payment, fees and privileges before signing or authorizing the change.
- Assuming a quote is guaranteed: Ask how long the offer is valid, what can change it and whether a new credit or income review is required.
- Forgetting taxes and insurance: If your payment includes property-tax or insurance amounts, separate those items from the mortgage principal-and-interest change.
If the lender will not convert the mortgage
Ask whether an early renewal or blend-and-extend is available, and request the calculation in writing. You can also compare a transfer or refinance, but obtain the current lender’s full payout cost first and confirm that you qualify with the new lender. If none of these options works, keep the existing mortgage and prepare for renewal by tracking payments, balance, amortization and your preferred term. A licensed mortgage professional can explain offers, but you should still verify every rate, fee and penalty in the lender’s documents.
Do not confuse conversion with a rate lock
US readers may encounter the term “rate lock.” The Consumer Financial Protection Bureau defines a lock as holding an interest rate between a loan offer and closing, subject to a specified period and no material application changes. That is an origination feature, not evidence that an existing adjustable-rate mortgage can be converted. Borrowers outside Canada should use their lender and local regulator for the rules that apply to an existing loan.

Frequently Asked Questions
Can I switch from a variable rate mortgage to a fixed rate mortgage at any time?
Not necessarily. Some Canadian lenders include a conversion feature, while others do not or impose a minimum term, fee or remaining-term condition. Check your contract and obtain the lender’s current written eligibility rules.
Best Value

- Comes with secure packaging
- Helpful in various ways
Will switching to fixed automatically lower my payment?
No. The lender uses the fixed rate available on the conversion date and your remaining balance and amortization. The payment may be higher than today’s variable payment, even though it becomes more predictable.
Is an internal conversion the same as breaking my mortgage?
No. An internal conversion amends the mortgage with the same lender if the contract permits it. Paying out the loan to transfer or refinance is a separate transaction that can trigger a prepayment charge and discharge, appraisal, legal or setup costs.
What is blend-and-extend?
It is an early-renewal arrangement in which the lender combines the rate on the remaining term with its current rate for a new term. It may avoid the usual prepayment penalty, but an administration fee, a new commitment and a different payment can apply.
How much can a Canadian lender charge to break a variable mortgage?
The amount depends on the contract and lender. The Bank of Canada’s 2026 staff paper describes three months of interest in the variable contracts it discusses, but that is not a personal quote or universal rule. Request a dated payout statement.
Can I transfer to another lender if its fixed rate is lower?
Possibly, but compare the full break, discharge, appraisal, legal, registration and setup costs and confirm that you qualify. Divide total costs by expected monthly savings and test whether the rate offer remains available through closing.
Does a fixed-payment variable mortgage protect me from rising rates?
It can keep the scheduled payment unchanged temporarily, but rising interest leaves less going to principal. At a trigger point, the lender may increase the payment, request a lump sum, change amortization or apply another contractual remedy.
Does TD’s conversion term rule apply to every lender?
No. TD’s published information says its selected term must be at least the lesser of three years or the remaining original term. That condition applies to the cited TD product information, not to all Canadian mortgages.

The Bottom Line
Start with the contract and your current lender, not an advertised rate. Confirm whether an internal conversion is allowed, then obtain written figures for the fixed offer, fees, payment, term and restrictions. Compare those figures with blend-and-extend, waiting for renewal and any transfer or refinance after including penalties, setup costs, qualification and exit flexibility. Accept the option whose total cost and payment risk fit your budget and plans.
