Short answer
At the scheduled end of your mortgage term, there is no early-break prepayment penalty, but switching or discharge fees may still apply. Breaking a closed mortgage before maturity normally carries a penalty. Three months’ interest and the Interest Rate Differential (IRD) are common methods; your contract determines the calculation. A 120-day rate hold is not a universal penalty-free break window.
Key takeaways
- Separate the prepayment penalty from discharge, legal, appraisal and other transaction costs.
- An open mortgage can be broken without a prepayment penalty; a closed mortgage normally cannot.
- Check your contract’s interest rate inputs and calculation method, not just the lender category.
- Confirm whether signing early changes the effective date or only holds an offer until maturity.
- Get a dated, written payout quote before deciding to break.
Quick example
Hypothetical fixed closed mortgage: $500,000 balance, 5.49% annual rate, 3 years left. Assume the contract charges the greater of three months’ interest or simplified IRD, and the IRD comparison rate is 3.99%. Three months’ interest is $6,862.50; simplified IRD is $500,000 × (5.49% − 3.99%) × 3 = $22,500. Under these assumed terms the penalty is $22,500, before other fees. This is not a lender quote; actual IRD inputs and methods differ.
What most people get wrong
- “No penalty means no cost.” Discharge and new-mortgage costs can remain even at maturity.
- “Signing 120 days early means I can leave immediately.” A hold for a future date and ending today’s contract are different actions.
- “All IRD formulas are the same.” Check the rate inputs, original discount, remaining term and rounding in your own contract. An online estimate is a starting point, not a dated payout quote.
Before comparing a lower rate, identify when the current term ends and which transaction you are considering. Then compare the full cost of staying, renewing early or breaking. A lower payment alone does not establish savings.
Natural Renewal: No Early-Break Penalty, but Check Fees
At scheduled maturity, paying off or transferring the mortgage is not an early break. Confirm the payout date and all fees. An open mortgage also permits breaking without a prepayment penalty; other charges may remain.
Rate hold, early renewal and breaking are different
- Rate hold: a quoted rate reserved for a defined period, subject to lender conditions. It does not itself discharge the existing mortgage.
- Early renewal: ask whether the new term starts now or at maturity, and whether a charge is waived. There is no universal 120-day entitlement.
- Blend-and-extend: if offered, FCAC explains that this early-renewal option avoids a prepayment penalty, but may have administration fees. The blended rate and longer term still need comparison.
- Early break or transfer: a closed contract normally has a prepayment penalty unless its terms or an agreed waiver provide otherwise.

Variable-Rate Penalty: Check the Three Months' Interest Clause
For a closed variable-rate mortgage, three months’ interest is a common contract method. Confirm the rate and balance used, any minimum charge and your prepayment privileges. Open variable mortgages are different. The distinction between fixed-payment variable and adjustable-rate mortgages concerns payments; it does not replace the penalty clause.
Enter a lender-confirmed penalty into the Ontario mortgage renewal calculator to compare scenarios. The tool does not determine your contract’s penalty.
Fixed-Rate Penalty: The Greater of 3-Months' Interest or IRD
Many fixed closed mortgages use the greater of three months’ interest or IRD. The contract and lender quote control; do not treat a simplified formula as a universal calculation.
For the $500,000, 5.49%, three-years-left example above, changing the assumed comparison rate to 4.99% gives a simplified IRD of $7,500. If it were 5.49%, IRD would be zero, but the assumed greater-of clause would still produce the $6,862.50 three-month-interest charge. Different inputs can change which method controls; these are not comparisons of actual lender offers.

Posted-Rate vs Discounted-Rate IRD: Check Your Contract
Posted-rate and discounted-rate inputs can produce different IRD estimates. FCAC describes calculations that may use the original posted rate or contract rate, and a current comparable posted rate with or without the original discount adjustment. The method varies by contract.
“Big 5,” “monoline” and “credit union” are not enough to identify a formula. Ask which two rates are being compared and how your original discount is treated. Compare the actual contracts rather than assuming every lender in a category has the same charge.
How to Verify Your Penalty Quote
Use this worksheet when requesting a written payout statement. Fill it from the lender’s documents; do not infer missing rate inputs from a public rate table.
- Transaction and dates: maturity, requested payout date, quote validity and whether a new contract starts early.
- Balance and interest: principal outstanding and accrued interest to payout, shown separately.
- Prepayment penalty: applicable clause, three-month-interest amount, IRD amount if applicable, and which amount controls.
- IRD inputs: both rates, original discount treatment, comparable term, remaining months/days, rounding and balance adjustments.
- Other charges: discharge/registration, administration, appraisal, legal fees and any cash-back repayment. Ask which are paid by the new lender and on what conditions.
- Alternatives: maturity payout, permitted prepayment, porting if moving, or an offered early-renewal option. Check deadlines and eligibility.
- Total and explanation: reconcile the line items and ask the lender to explain any difference from your estimate. A simplified IRD need not equal its contractual calculation.
Keep the quote date and expiry with your comparison. If the balance, rates or payout date change, request an updated amount before committing.
Penalties When Refinancing or Switching
A mid-term refinance or transfer of a closed mortgage normally triggers the contract’s prepayment terms. An open mortgage or an agreed lender waiver can change that. At scheduled maturity, no early-break penalty applies, but setup and discharge costs can remain.
A HELOC is separate borrowing with its own eligibility, fees and risks; it is not a blanket penalty-avoidance route. See the HELOC versus refinancing guide. FCAC’s renewal guidance lists transfer costs and notes that a new lender must approve the application.
Frequently asked questions
Is there a penalty to renew a mortgage in Canada?
At scheduled maturity there is no early-break prepayment penalty, but discharge and switching costs may remain. Breaking a closed mortgage before maturity normally carries a penalty; an open mortgage or a contract-specific waiver can change that.
What is the Interest Rate Differential (IRD)?
IRD compares interest under two contract-defined rates over the remaining term. A simplified estimate is the rate difference times balance times remaining years. Many fixed closed mortgages charge the greater of IRD or three months’ interest; your contract determines the actual method.
Why can bank and monoline mortgage penalties differ?
Rate inputs, discount treatment and contract terms can differ. Do not assume every bank, monoline or credit union uses one formula. Ask for the exact rates and calculation on your written payout quote.
How do I get an accurate mortgage penalty quote?
Ask your lender for a dated written payout statement for your intended payout date, with the penalty calculation and other fees separated. Confirm its expiry and request an update if the inputs change. An online calculator gives an estimate, not a payout commitment.
Is there a penalty for signing a renewal offer in the 120-day window?
There is no universal penalty-free 120-day window. A rate held for maturity is different from starting a new term early or transferring now. Confirm the effective date, fees and any waiver in writing. An offered blend-and-extend can avoid a prepayment penalty but may have administration fees.
Confused about your penalty quote?
Bring your contract and dated payout quote to a discovery call to discuss the assumptions and alternatives. A lender must confirm the actual charges.
Check the effective date and separate the penalty from other fees before deciding.
