What is mortgage refinancing?
Mortgage refinancing means replacing your current mortgage with a new mortgage or increasing the amount borrowed against your property. Homeowners may explore it to change their rate or amortization, consolidate other debt, fund renovations, or restructure borrowing after a major life event.
Refinancing is not automatically beneficial. A new payment may be lower because the interest rate is lower, because the repayment period is longer, or both. A longer amortization can improve monthly cash flow while increasing the amount of interest paid over time.
When might refinancing be worth comparing?
Consolidating higher-cost debt
Some homeowners consider adding credit-card, personal-loan or other debt to a mortgage. This may reduce the interest rate or monthly payment, but it also converts unsecured debt into debt secured by the home and may stretch repayment over many years. The Financial Consumer Agency of Canada’s debt-consolidation guidance explains products and risks to compare.
Approaching mortgage renewal
Renewal is an opportunity to review rates, features and lenders. Switching providers may involve qualification, appraisal, legal or administrative requirements. Review the FCAC mortgage-renewal checklist before accepting or replacing an offer.
Funding a substantial renovation
Using home equity may be one way to finance a renovation, but it increases property-secured debt. Compare a full refinance with alternatives such as a home-equity loan or line of credit, and account for variable-rate exposure where applicable.
Changing ownership or household finances
Separation, buying out a co-owner, income changes and estate matters can create a need to restructure a mortgage. These situations may require independent legal, tax or financial advice beyond a lending comparison.
Costs to include in a refinancing comparison
- Prepayment penalty: a closed mortgage may charge a penalty when broken before the term ends.
- Discharge or administrative fees: the existing lender may charge fees to close or transfer the mortgage.
- Legal fees: legal work may be required to register the new financing.
- Appraisal fees: the provider may require a current property valuation.
- Interest over time: extending amortization can increase total interest even when monthly cash flow improves.
- Optional insurance or product fees: review which products are optional and their complete cost.
Ask your current lender for a written payout statement and penalty estimate. FCAC explains how breaking a mortgage contract can involve costs and trade-offs.
How to estimate home equity
Estimated equity is the property value minus all borrowing secured against the property. For example, a property estimated at $700,000 with $400,000 owing has approximately $300,000 in gross equity before transaction costs. A provider may rely on an appraisal that differs from the owner’s estimate and will apply its own lending criteria.
The loan-to-value ratio is total property-secured borrowing divided by the property value. It is a useful planning measure, but it does not determine approval by itself.
Refinancing checklist
- Obtain the current mortgage balance and exact penalty estimate.
- List all debts or project costs you intend to include.
- Estimate the property value conservatively.
- Compare both monthly payments and total borrowing costs.
- Review the new rate, term, amortization and prepayment privileges.
- Confirm legal, appraisal, discharge and administrative fees.
- Consider the risks of securing previously unsecured debt against your home.
- Review the final disclosure and provider terms before proceeding.
Understand the break-even estimate
A monthly payment reduction does not automatically mean lower total interest. Our Canadian refinance break-even guide walks through upfront costs, monthly cash-flow improvement and the limitations of a simple recovery estimate.
