Usually, not on the lower rate alone. In Canada, breaking a mortgage can make sense only when the interest and payment savings over a defined period exceed the lender’s prepayment charge, discharge and setup costs, any cash-back repayment, and the cost of the replacement mortgage’s terms. Get the lender’s current penalty in writing, then compare an early switch with blend-and-extend and simply waiting for renewal.
Start with the Canadian rule that determines the decision
This guidance is for mortgages in Canada. Mortgage law, contract wording and penalty calculations differ by country, so do not apply these rules automatically elsewhere.

Financial Consumer Agency of Canada (FCAC) consumer guidance puts the central issue plainly: “The cost to break your mortgage contract depends on whether you have an open or closed mortgage.” A closed mortgage normally charges a prepayment penalty when you end the contract before the term expires. An open mortgage generally lets you repay or break it without that prepayment penalty. A closed mortgage can still give you limited prepayment privileges, such as the ability to make specified extra payments, but those privileges do not necessarily let you cancel the whole contract without charge.

Your agreement, lender and remaining term control the actual amount. A rate quoted by a new lender is not enough to answer whether switching saves money. FCAC also advises: “Make sure the benefits of breaking your mortgage contract will save you money once you include all the fees.”

When a lower rate can be worth the cost
The practical test is a break-even comparison:
Expected savings over the comparison period − all switching costs = net benefit.
Expected savings should use the same balance, payment frequency and comparison period for every option. Include the interest and principal effects of the replacement mortgage, not just the difference between advertised rates. The comparison period might run to your existing renewal date, the end of the proposed new term, or another period that matches your plans. State the period before calculating; changing it can reverse the apparent result.
Switching is financially attractive only if the net benefit is positive and the new contract’s conditions suit you. A lower payment can result from stretching amortization rather than from a genuine reduction in total interest. Compare the actual term, amortization, payment schedule and prepayment rules.

List every cost before comparing rates
Request a current payout or penalty estimate directly from your lender. Ask for the calculation in writing and confirm the date it is valid. The amount can depend on contract details and may change as your balance, remaining term or the lender’s comparison rate changes.

- Prepayment penalty: This is the principal cost for breaking a closed mortgage before the term ends. The lender’s contract and calculation method determine it.
- Mortgage discharge costs: Ending the existing mortgage can involve a discharge or administration charge.
- Administration and appraisal costs: A switch or refinance may require lender administration, property appraisal or related processing.
- Replacement-mortgage fees: Ask the new lender whether it charges setup, registration or other fees, and whether either lender will pay or waive them.
- Cash-back repayment: If your current mortgage included cash back, the contract may require some or all of it to be repaid when you break the mortgage early.
- Different contract conditions: A new term can have different prepayment privileges, portability rules, payment options or qualification requirements. Put a value on the flexibility you would give up, even when no separate fee appears on the statement.
Do not subtract a quoted monthly payment from your current payment and call the difference savings. A payment can fall because the new mortgage has a longer amortization or a different repayment structure. Use the lender’s amortization schedules or a documented calculation of interest and principal for the same period.
Compare the four realistic choices
| Option | What happens | Costs and questions to check |
|---|---|---|
| Keep the mortgage until renewal | You continue the existing contract and negotiate or shop when the term ends. | Compare renewal offers and other lenders at renewal; there is no early-break penalty from ending the term before its scheduled date. |
| Blend-and-extend | The lender ends or extends the current term early and blends your existing rate with the rate for a new term. | FCAC says this option avoids a prepayment penalty, but administrative fees may apply. Confirm the blended-rate formula, new term, payment, amortization and all conditions. |
| Switch lenders now | You discharge the current mortgage and arrange a replacement mortgage before renewal. | Include the current lender’s penalty, discharge and other costs, replacement setup fees, any cash-back repayment, and the new contract’s interest and conditions. |
| Port the mortgage when moving | You transfer the existing balance, rate and conditions to another property, subject to the lender’s rules. | Check eligibility, timing, property restrictions and how the balance changes. A cheaper replacement home or a mortgage that cannot be ported may still trigger a penalty. |
Keeping the mortgage until renewal
Waiting is often the cleanest baseline because you avoid an early-break charge. At renewal, you can negotiate with your current lender and compare other lenders. It is not a promise that rates will be lower then; it is a way to avoid paying today’s penalty in exchange for a future rate that is not yet known. Use the interest you will pay during the remaining term as part of the comparison, rather than assuming waiting is free.
Blend-and-extend
Ask the current lender for a written blend-and-extend quote. It may permit an early extension without the prepayment penalty, but the resulting blended rate is not necessarily the lowest available rate. Compare the new term and total interest with both a switch and waiting. Ask whether an administration fee applies and whether the lender changes prepayment privileges or other conditions.

These are FCAC’s example inputs, not a current market quote or an individualized offer. Your lender’s formula and rates can produce a different result.
Switching lenders now
A switch can be sensible when the replacement mortgage’s savings are large enough to recover every cost before the comparison period ends. Obtain a firm offer that states the rate, term, amortization, payment, fees and conditions. Confirm that you qualify under the new lender’s underwriting rules; approval is not automatic merely because you already have a mortgage. Ask both lenders which fees they will pay or waive, and obtain documentation rather than relying on a verbal promise.
Portability when you are moving
If a move is causing the decision, ask whether your mortgage is portable. Portability may let you transfer the balance, rate and conditions to a new property, but lender eligibility and restrictions apply. The lender may impose timing, property or balance requirements. If the new home costs less, the mortgage cannot be ported, or you do not meet the conditions, a penalty can still result. Compare the ported loan with a new mortgage and include any shortfall, fees and changed terms in writing.

Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problems- Current contract: balance, rate, payment frequency, amortization remaining, term end date and prepayment privileges.
- Early-break costs: the lender’s dated penalty estimate, discharge and administration charges, appraisal costs, cash-back repayment and any other fee.
- Replacement offer: rate, term, amortization, payment, setup fees, conditions and qualification requirements.
- Alternative quotes: blend-and-extend terms and a renewal or wait scenario using the interest paid until renewal.
- Flexibility: portability, lump-sum privileges, payment increases and any restrictions that differ between contracts.
Then calculate the interest and principal paid under each option through the same end date. Add one-time costs to the early-switch option. If the replacement term ends before your chosen comparison date, make an explicit assumption about the rate after that term; do not quietly treat an unknown future rate as zero or as today’s offer.

The break-even time is the point at which cumulative interest and payment savings equal the penalty and other one-time costs. There is no universal break-even number. It changes with your balance, months left, lender’s penalty method, replacement rate and term, fees and assumptions about what happens afterward.
Questions to ask your lender and broker
- Is the mortgage open or closed, and what exact prepayment privilege applies?
- What is the current payout amount and penalty if I break on a specified date?
- Which part of the estimate is the prepayment charge, and which amounts are discharge or administration fees?
- Will I have to repay cash back, and how is that amount calculated?
- Can you provide a blend-and-extend quote, including the blended-rate formula, term, payment and fees?
- Is the mortgage portable if I move, and what property, timing or balance restrictions apply?
- What rate, term, amortization, payment, privileges and fees would apply to the replacement mortgage?
- Will either lender pay or waive appraisal, administration, legal or discharge costs?
- What qualification documents or approval tests apply to the new mortgage?
- How long is each quote valid, and can the penalty change before closing?
Common mistakes that produce a false saving
Comparing headline rates with different terms
A short term at one rate and a longer term at another are not identical products. Compare total interest, term length, renewal exposure and conditions. A lower initial rate can leave you refinancing sooner or paying more under a different amortization.
Ignoring the penalty because it is “only one number”
The penalty can be the largest switching cost. Do not use an online estimate as a substitute for the lender’s current written calculation when the contract-specific amount is available.

Forgetting cash-back repayment
Cash back received at origination can become repayable when you end the mortgage early. Check the original agreement and include the required repayment in the first-year cost of switching.

Assuming a lower payment means lower cost
Check amortization and total interest. A longer repayment period can lower the monthly payment while increasing the interest paid over the life of the mortgage.
Leaving qualification and flexibility until the end
A new lender may require updated income, debt and property information. The new contract may also have less favorable prepayment or portability provisions. Resolve those issues before paying a penalty or giving notice to the current lender.
A decision checklist
- Confirm that the Canadian rules apply to your situation.
- Identify whether the mortgage is open or closed, fixed or variable, and note the term-end date.
- Request a dated payout and penalty estimate in writing.
- Collect every discharge, administration, appraisal, setup and cash-back amount.
- Obtain a complete replacement offer, not just an advertised rate.
- Request a blend-and-extend quote and record its new term and fees.
- Calculate the keep-until-renewal scenario over the same period.
- If moving, test portability and the lender’s restrictions.
- Compare total interest, payments, term, qualification and flexibility.
- Switch only when the documented net benefit remains positive after allowing for rate and timing uncertainty.
What the evidence does—and does not—tell you
FCAC’s guidance supports comparing the complete costs and benefits of breaking, blending, switching and waiting. It does not establish a typical Canadian penalty, an average saving or a guaranteed break-even period. Those figures cannot be responsibly generalized because lenders and contracts calculate charges differently and borrowers have different balances and remaining terms.
