Renewal vs. refinance: what's the difference?

A plain-language guide for Ontario borrowers · Last updated October 2026

Key takeaways

• Renewal = end of term, no penalty, same balance. Refinance = new mortgage, during the term or at maturity; a prepayment penalty usually applies if a closed mortgage is broken before maturity, and the balance usually changes.
• A renewal offer from your lender is a starting position - shop it about four months before your term ends.
• Refinancing mid-term triggers a penalty (three months' interest or an interest-rate differential on fixed rates), legal costs, and the stress test.
• Refinancing makes sense when the math works: debt consolidation, accessing equity, or a much better rate.
• Switching lenders at renewal is not refinancing - it's still a renewal, and usually penalty-free.

Renewing, in plain language

A mortgage term - typically five years, sometimes shorter or longer - is a contract with an end date. When it ends, you renew: you sign a new term for whatever balance is left, at whatever rate and terms you agree to. That's it. The balance stays the same, no new money is borrowed, and there's no prepayment penalty, because you're not breaking anything - the contract simply ran its course.

Renewing with your current lender is the simplest path: no legal fees, no appraisal, no re-qualification under the stress test in most cases. But "simplest" isn't the same as "best." Your lender will mail you a renewal offer before the term ends - and that offer is a starting position, not a final answer. More on that below.

Refinancing, in plain language

Refinancing means replacing your current mortgage with a new one - often to access equity or change the amortization. It can happen during the term or at maturity. Breaking a closed mortgage before maturity usually triggers a prepayment penalty; refinancing at maturity generally avoids that penalty, although other costs may apply. Either way, it's a brand-new mortgage, so you go through full qualification again - credit check, income verification, appraisal, the stress test, the works. There are also legal costs, since the old mortgage has to be discharged and the new one registered.

So why would anyone do it? Because refinancing changes the mortgage itself: you can borrow additional money against your home equity, fold high-interest debt into a lower-rate mortgage, change your amortization, or move to a meaningfully better rate. It's a tool for restructuring your finances - and like any tool, it either pays for itself or it doesn't.

Renewal vs. refinance, side by side

Factor	Renewal	Refinance
Timing	At the end of your term	During the term or at maturity
Penalty	None - the contract ran its course	Usually applies if a closed mortgage is broken before maturity
Legal costs	None with the same lender; often covered by the new lender if you switch	Yes - discharge and re-registration
Credit check & re-qualification	Usually not required with the same lender; required if switching	Yes - full application
Stress test	Generally exempt with the same lender	Applies
Borrowing more money	No - balance stays the same	Yes - that's the main reason people do it
Purpose	Lock in a new rate and terms for the next term	Access equity, consolidate debt, restructure

The penalty question

The penalty is the biggest practical difference, so it's worth understanding properly. If you break a variable-rate mortgage mid-term, the penalty is typically three months' interest - straightforward and usually modest.

Fixed-rate mortgages are trickier. The penalty is usually the greater of three months' interest or an interest rate differential (IRD). The IRD is the lender's way of estimating the interest it loses because you paid out early: roughly, the difference between your contract rate and the rate the lender could get today, multiplied by your remaining balance and the time left in your term. When rates have fallen since you signed, the IRD can be substantial - several months of payments, sometimes more. When rates have risen, three months' interest is usually the number that applies.

The key point: never guess at your penalty. Ask your lender for the exact figure in writing before you make any decision. A refinance that looks brilliant on paper can fall apart once the real penalty lands - and occasionally the penalty is smaller than expected, which opens doors.

When to simply renew (or switch at renewal)

If your term is ending and you don't need to borrow more money, renewal is almost always the right move. No penalty, minimal cost, minimal hassle. The decision is really where to renew: with your current lender, or with a new one.

Switching lenders at renewal is still a renewal, not a refinance - there's no penalty, and the new lender will usually cover the legal and appraisal costs to win your business. The new lender will assess your application, and whether the prescribed stress test applies depends on whether the transfer qualifies for a straight-switch exemption. For most borrowers with stable income and decent credit, that's not a problem - and the savings from a better offer can be significant.

Start the process about four months before your term ends. That gives time to compare offers, negotiate with your current lender (who may improve their offer once they know you're shopping), and complete a switch without rushing.

When refinancing mid-term makes sense

Refinancing is worth it when the benefit clearly outweighs the penalty and costs. Common cases:

Consolidating high-interest debt

Rolling credit card balances or a car loan into your mortgage replaces high-interest debt with mortgage-rate debt. The monthly savings can be dramatic - but only refinance debt you're committed to not rebuilding.

Accessing equity for a renovation

If your Barrie home has appreciated and you need funds for a renovation that adds value - a legal basement suite, for example - refinancing can be cheaper than other borrowing. Run the numbers on the added value, not just the added debt.

Your penalty is small and the rate gap is large

Sometimes the math just works: a modest three-month interest penalty against years of lower payments. This is a break-even calculation - how many months until the savings repay the penalty? If the answer is well within the new term, it's worth a serious look.

Life has changed the mortgage you need

Separation, a new business, a move from variable to fixed for certainty - sometimes the mortgage you signed no longer fits. Refinancing restructures the debt to match the new reality, penalty and all.

Don't sign the first renewal offer

This deserves its own section, because it's the single most common - and most avoidable - way Ontario homeowners overpay. The renewal letter arrives, the rate looks plausible, life is busy, and the signature goes on. Done.

Here's what actually happens behind that letter: lenders know most borrowers won't shop around, so the first offer rarely reflects their best terms. We've seen borrowers accept a renewal rate and later discover meaningfully better options were available - from their own lender, once negotiated, or from a competitor. A broker's job at renewal is simple: compare the market, push back on the offer, and make sure you're not paying an inertia tax.

Four months before your term ends, that's the window. Mark it on your calendar now - or better, let us track it for you and reach out when it's time.

Questions to ask before you decide

• What is my exact prepayment penalty, in writing? Not an estimate - the real number, as of today.
• What is my break-even point? How many months of savings does it take to repay the penalty and costs?
• Am I borrowing more, or just changing terms? If the balance isn't changing and your term is nearly up, renewal is usually the answer.
• Will I pass the stress test? Refinancing generally requires it; a straight renewal usually doesn't. Whether it applies to a switch depends on whether the transfer qualifies for a straight-switch exemption.
• What are the full terms, not just the rate? Penalty calculation, portability, prepayment privileges - the fine print from our buyer mistakes guide applies at renewal too.
• Is there a cheaper way to get what I need? A home equity line of credit or a small second mortgage sometimes beats a full refinance.
