What Is a Mortgage Refinance?
A mortgage refinance replaces your existing mortgage with a new one — typically with a different lender, rate, term, or balance. In Ontario, refinancing is one of the most powerful tools available to homeowners who have built equity, but it comes with trade-offs that need to be modelled before committing.
The key question is always: does the financial benefit of refinancing outweigh the cost of breaking your current mortgage? That calculation depends on your lender type, remaining term, rate differential, and what you intend to do with the proceeds.
The Four Reasons Clients Refinance
- Rate reduction — securing a materially lower rate mid-term when the penalty is worth paying
- Cash-out / equity access — pulling equity as a lump sum for debt consolidation, renovations, investment, or major expenses
- Debt restructuring — rolling high-interest consumer debt (credit cards, lines of credit, car loans) into one lower-rate payment
- Term or structure change — switching variable to fixed, removing a co-borrower, changing amortization, or moving to a different lender
Understanding the Penalty: Fixed vs. Variable
Breaking a mortgage early triggers a prepayment charge. The type and size of that charge depends on whether your mortgage is fixed or variable rate — and which lender holds it.
Variable-rate mortgages almost always carry a penalty of 3 months' interest. On a $500,000 balance at 5.5%, that's approximately $6,875. Relatively predictable and often manageable.
Fixed-rate mortgages use the greater of 3 months' interest or the Interest Rate Differential (IRD). The IRD calculation compares your contract rate to the lender's current posted rate for the remaining term — and big banks use a posted-rate method that systematically inflates the penalty. On a fixed mortgage with 3+ years remaining, IRD penalties of $15,000–$30,000 are common. Monoline lenders (non-bank lenders used by brokers) calculate IRD more fairly.
Important: Never make a refinance decision based on a rate comparison alone. Paul will calculate the actual penalty using your mortgage statement before recommending any action. A lower rate only wins if the break-even timeline fits your plans.
Cash-Out Refinance: Accessing Your Equity
If your property has appreciated or you've paid down your mortgage significantly, a cash-out refinance lets you access that built-up equity as a lump sum. Most lenders allow a new mortgage up to 80% of the property's current appraised value.
Example: A $900,000 home with a $520,000 mortgage has $220,000 in accessible equity (80% of $900,000 = $720,000, minus the $520,000 balance). Those funds can be used for any purpose — no restrictions, no reporting requirement.
Refinancing With Poor Credit or as a Self-Employed Borrower
A-lenders (major banks, credit unions) apply the mortgage stress test and require income documentation. If your credit has deteriorated or you don't show sufficient T4/NOA income, you still have options through B-lenders and private mortgage lenders.
- B-lenders (trust companies, monoline B products) offer alternative income qualification and accept lower credit scores — rates typically 1–2% above A-lender pricing
- Private lenders focus almost entirely on equity position and property location — credit and income play a secondary role
- Bridge financing can be used short-term while you restore qualification for A-lender rates
Refinance vs. Renewal: Key Differences
At renewal, your mortgage term ends and you renegotiate — with no penalty. A refinance happens mid-term and incurs a prepayment charge. In some cases, it still makes sense to refinance before renewal — particularly if rates have dropped significantly, or if you need equity access urgently and can't wait. The break-even calculator above helps model that decision.
The Refinance Process in Ontario
The process is straightforward when you work with a broker who manages it end-to-end: assessment call (15 min) → review mortgage statement and confirm penalty → obtain appraisal if required → lender submission and approval → legal discharge of existing mortgage and registration of new one. For A-lender refinances, timeline is typically 3–5 weeks. Urgent private refinances can close in 5–7 business days.
