Refinance costs and decision-making
Mortgage Refinance Costs in Ontario
The largest refinancing cost is often the penalty for breaking an existing closed mortgage, but appraisal, legal, discharge, registration and lender-related fees may also apply. The exact total depends on your present contract, lender, property and new mortgage structure.
Possible costs include a mortgage prepayment penalty, lender administration charges, appraisal, legal work, title search or insurance, mortgage discharge and new registration, plus lender or brokerage fees on some transactions. Obtain written estimates before deciding whether the payment or interest benefit justifies the cost.
What costs can apply to a mortgage refinance?
| Potential cost | Why it may apply | Who confirms it |
|---|---|---|
| Prepayment penalty | Existing closed mortgage is repaid before maturity | Current lender |
| Administration or reinvestment fee | Existing lender processes an early payout | Current lender |
| Appraisal or valuation | New lender must confirm property value and acceptability | New lender or appraiser |
| Legal and title work | Lawyer reviews title, handles payouts and registers financing | Lawyer or closing provider |
| Discharge or assignment fee | Existing charge is removed, transferred or assigned | Current lender and lawyer |
| Registration cost | New mortgage charge is registered on title | Lawyer or closing provider |
| Lender fee | May apply with alternative, private or specialized financing | New lender |
| Brokerage fee | May apply on certain alternative or private transactions | Mortgage brokerage |
| Cashback repayment | Original mortgage incentive must be repaid under its terms | Current lender |
Not every refinance includes every cost. Some lenders may cover or waive selected expenses, while other files require additional work. Treat online ranges as rough context only and obtain figures for your transaction.
1. Mortgage prepayment penalty
A prepayment penalty may apply when a closed mortgage is paid out before the end of its term. FCAC notes that this cost can reach thousands of dollars. An open mortgage can generally be repaid without a prepayment penalty, although other charges may still apply.
For many closed variable-rate mortgages, the penalty is commonly based on three months’ interest. For many closed fixed-rate mortgages, the contract may require the greater of three months’ interest or an interest rate differential, often called an IRD. The lender’s contract and calculation method control the actual result.
Lenders can use different comparison rates, discounts and calculation methods. Ask the existing lender for a written payout statement or penalty quote and confirm how long the estimate remains valid.
2. Appraisal or property valuation
The new lender may require an appraisal to confirm market value, property condition and acceptability. Some lenders use automated or alternative valuation methods instead. The required method depends on the property, location, requested loan-to-value and lender policy.
The borrower may need to pay the appraisal fee upfront. In some transactions, the lender or brokerage may reimburse it after funding, but this should not be assumed unless confirmed in writing. An appraisal below the expected value can also reduce the amount available—not just add a cost.
3. Legal, title and closing expenses
Refinancing generally requires legal or closing work because the existing mortgage must be paid, lender instructions must be satisfied and the new financing must be registered against the property. The lawyer or closing provider may also complete title searches, arrange title insurance, verify identity and direct approved debt payouts.
The final legal account may include professional fees, tax where applicable, title insurance, searches, registrations and other disbursements. Ask for an estimate that separates these items and confirm whether unusual title issues or additional payouts could increase the cost.
4. Mortgage discharge, assignment and registration charges
When changing lenders, the property title must be updated. FCAC explains that the old mortgage may need to be discharged and the new lender added to title. Some lenders charge discharge or assignment fees, and Ontario land-registration charges may apply through the legal closing.
A collateral charge can make a lender change more involved because other credit products may also be secured under the registration. Ask the current lender or lawyer how the mortgage is registered and what must be repaid, transferred or discharged.
5. Lender and brokerage fees
Many prime residential mortgages compensate the brokerage through the lender and do not involve a direct brokerage fee to the borrower. Alternative, private, short-term or specialized mortgage options may include a lender fee, brokerage fee or both. Any such charges should be clearly disclosed before the borrower commits.
Compare the rate, fees, term, exit costs and expected time in the product together. A lower stated rate does not automatically produce the lowest complete borrowing cost.
Compare the payment before deducting costs
Use the calculator for an initial refinance scenario, then add the actual penalty and transaction costs.
Illustrative refinance-cost example
Assume a homeowner is increasing a $350,000 mortgage to consolidate $35,000 of unsecured debt. For consistency with the other hub examples, assume $7,000 for the mortgage penalty and closing-related costs combined.
How costs affect the new mortgage
| Item | Illustrative amount |
|---|---|
| Existing mortgage payout | $350,000 |
| Unsecured debts paid at closing | $35,000 |
| Assumed penalty and closing-related costs | $7,000 |
| New mortgage | $392,000 |
The $7,000 figure is an assumption—not a standard fee estimate. The actual penalty and closing costs may be lower or higher. Figures are rounded and are not a quote or approval.
The homeowner is not borrowing only the $35,000 required for consolidation. The mortgage rises by $42,000 because the assumed transaction costs are financed as well. If those costs remain in the mortgage, interest is charged on them according to the mortgage terms.
Should costs be paid in cash or added to the mortgage?
Some costs may need to be paid upfront, while others may be deducted from the advance or added to the new mortgage when there is sufficient equity and lender approval.
Paying costs from available cash keeps the mortgage balance lower. Adding them to the mortgage preserves cash today but means they may be repaid with interest. Compare both versions and avoid using all available savings if doing so would leave the household without a reasonable emergency reserve.
How to calculate the refinance’s net benefit
A refinance should be evaluated over a defined comparison period. If you expect to keep the new mortgage for three years, compare the costs and projected balances over three years—not only the first payment.
- Calculate the monthly cash-flow difference. Compare all payments that will be replaced with the new mortgage payment.
- Choose a relevant time period. This may be the new mortgage term, expected sale date or another realistic decision point.
- Add transaction costs. Include the penalty, legal work, appraisal and every disclosed lender or brokerage charge.
- Compare remaining balances. A lower payment created by a longer amortization can leave a higher mortgage balance.
- Account for debts that remain. Do not treat a payment as eliminated unless the balance is actually paid at closing.
A simple cash-flow break-even calculation divides upfront costs by the monthly payment reduction. For example, $7,000 of costs divided by a $1,057 monthly reduction equals approximately 6.6 months. That only measures when the cumulative cash-flow difference matches the costs. It does not establish total savings because it excludes balance differences, interest over time and future rate changes.
Ways refinancing costs may be reduced or avoided
- Wait until maturity: refinancing at renewal may avoid a mid-term prepayment penalty when the need can safely wait.
- Use permitted prepayments: a lump sum within the contract’s privilege may reduce the balance used for a later penalty calculation. Confirm timing and restrictions first.
- Ask about a blend-and-extend: the current lender may offer a blended option without a standard break penalty, although terms and administration costs require comparison.
- Request a same-lender increase: some lenders can add funds or restructure borrowing without a complete lender change. Costs and qualification still apply.
- Compare a HELOC or second mortgage: preserving the first mortgage may make sense when its penalty is large, but the new borrowing may carry higher pricing or fees.
- Ask what the new lender covers: some transfer or refinance offers may cover selected appraisal or legal expenses.

How costs affect available equity
When costs are added to the mortgage, they use part of the homeowner’s borrowing room. A property-based maximum is commonly calculated at up to 80% of the lender-accepted value. Subtract the existing mortgage, other secured debts, required payouts and costs to estimate net funds.

Frequently asked questions
How much does it cost to refinance a mortgage in Ontario?
There is no universal amount. The total depends heavily on the existing mortgage penalty and may also include appraisal, legal, title, discharge, registration, administration and lender or brokerage fees.
Can I refinance without paying a penalty?
Potentially, such as at maturity or with an open mortgage. A same-lender option or blend-and-extend may also avoid a standard break penalty, but other costs and conditions may apply.
How is a fixed-mortgage penalty calculated?
Many closed fixed contracts use the greater of three months’ interest or an interest rate differential. Calculation methods vary, so obtain the actual amount from the lender rather than relying on a generic formula.
Are legal fees always required?
Refinancing normally involves legal or closing work to handle lender instructions, payouts and property-title registration. The process and cost depend on the lender and transaction.
Can refinancing fees be added to the mortgage?
Often some costs can be included when sufficient equity and qualification exist. This increases the mortgage and may cause the costs to accrue interest.
Does the refinance calculator include every cost?
No. It provides an initial comparison using entered assumptions. Obtain current penalty, legal, appraisal and other fee estimates before making a decision.
