What is mortgage refinancing? Refinancing means breaking your current mortgage and replacing it with a new one, sometimes with a different lender. People refinance to get a lower interest rate, access built-up home equity or consolidate higher-interest debt. The main cost to watch is the pre-payment penalty, which can be significant on a fixed-rate mortgage. Whether refinancing makes sense depends on whether the long-term savings outweigh those upfront costs.
Refinancing is not the right move for everyone, but in the right situation it can meaningfully improve your financial position. This guide covers the main reasons homeowners refinance, how the process works, what it costs and when it is worth doing.
If you are unsure what your home is currently worth or how much equity you have built up, a free home evaluation is a good starting point. You can also visit our mortgage hub for more on your options.
Why Homeowners Refinance
Lower Interest Rate
If rates have dropped since you signed your mortgage, refinancing to a lower rate can save you a meaningful amount over the remaining life of your loan. The key is to compare those savings against the cost of breaking your existing mortgage. If the long-term savings are greater than the penalty, it is worth exploring.
Access Home Equity
When you refinance, you can typically access up to 80% of your home's current value minus your outstanding mortgage balance. For Oakville homeowners who have seen significant appreciation, this can represent a substantial amount of accessible cash. Common uses include home renovations, helping a child with a down payment or funding other investments.
Debt Consolidation
If you are carrying high-interest debt such as credit cards or a personal loan, folding those balances into your mortgage at a much lower interest rate can reduce your overall monthly payments considerably. This approach requires discipline since you are effectively converting short-term debt into long-term mortgage debt, but for the right situation it can be a genuinely useful financial tool.
Switching Rate Types
Refinancing also gives you the option to move between fixed and variable rate mortgages based on where rates are heading and your own comfort with uncertainty.
- Lower interest rate and reduced long-term cost
- Access to built-up home equity
- Consolidate high-interest debt at a lower rate
- Opportunity to switch rate type
- Reset mortgage terms to fit your current situation
- Pre-payment penalties can be significant
- Legal costs and administrative fees
- Extending your amortization increases total interest paid
- Consolidating debt resets repayment timelines
- New rate may not be better than what you have
How to Refinance: Your Options
Break Your Mortgage and Start a New One
The most straightforward approach is to end your current mortgage contract and replace it with a new one. This gives you the most flexibility to shop for the best rate and terms across multiple lenders. The trade-off is the pre-payment penalty, which you will owe to your existing lender for breaking the contract early.
Home Equity Line of Credit (HELOC)
A HELOC lets you borrow against the equity in your home on an ongoing basis, similar to a revolving credit line. Because the loan is secured by your property, the interest rate is significantly lower than an unsecured credit card or personal loan. This option works well if you want flexible access to equity over time rather than a lump sum.
Blend and Extend
Some lenders offer a blend-and-extend option where they combine your existing mortgage rate with the current market rate to create a blended rate, and extend your term. This avoids the pre-payment penalty entirely. The downside is that blended rates are often higher than what you could get by breaking and taking the best available rate on the market. Check our mortgage rate comparison to see how the numbers stack up.
What Refinancing Costs
Pre-payment penalties are the biggest cost to understand. For a fixed-rate mortgage, the penalty is typically the greater of three months' interest or the Interest Rate Differential (IRD). The IRD can be very large depending on how much rates have moved since you signed. For a variable-rate mortgage, the penalty is usually just three months' interest, which is much more predictable.
Legal costs are also involved since changes need to be registered on the title of your property. For mortgage balances over $200,000, many lenders and brokers will cover these costs as part of the refinancing deal. It is worth asking upfront.
When Does Refinancing Make Sense?
Refinancing makes the most sense when what you gain is clearly greater than what you pay to get there. A good rule of thumb: if you can recover the cost of the pre-payment penalty within 12 to 24 months through lower payments or interest savings, the math usually works. If it takes five or more years to break even, it is worth reconsidering.
The best situations for refinancing are when you can lock in a meaningfully lower rate, when you have significant equity to access for a specific purpose or when consolidating debt will reduce your total monthly obligations in a material way.

Fixed vs variable: which is right for your refinance?
If you are refinancing, you will need to choose a rate type again. Our guide to fixed vs variable mortgage rates breaks down the key differences and how to decide.
The question I get from homeowners most often is whether the penalty to break is worth it. The honest answer is that it depends entirely on your specific numbers, and the only way to know for sure is to get your lender to tell you exactly what the penalty would be and then model out what you would save over the next few years at a lower rate. A lot of people assume the penalty is too high without actually running the math. Sometimes it is. Sometimes it is not as bad as expected and refinancing makes clear sense.

Frequently Asked Questions
What is the difference between refinancing and renewing a mortgage?
Renewing happens at the end of your mortgage term when your contract naturally expires. At renewal, you can switch lenders or renegotiate terms without a penalty. Refinancing happens mid-term, before your contract ends. Because you are breaking the agreement early, you pay a pre-payment penalty. Refinancing gives you more flexibility but comes at a cost. Renewal costs nothing to switch.
How much home equity can I access when refinancing?
In Canada, you can typically access up to 80% of your home's current appraised value minus your outstanding mortgage balance. For example, if your home is worth $1.2 million and you owe $600,000, you have access to up to $360,000 in equity through a refinance. The lender will require an appraisal to confirm the current value.
How much does it cost to refinance a mortgage in Canada?
The main costs are the pre-payment penalty and legal fees. The penalty on a fixed mortgage can range from a few thousand dollars to tens of thousands depending on the IRD calculation. Legal fees are typically $1,000 to $1,500 but are often covered by the lender if your mortgage is above $200,000. Ask any lender you are considering about what they cover before committing.
Can I refinance if I have a variable-rate mortgage?
Yes. Variable-rate mortgages are generally easier and less expensive to break. The penalty is typically three months' interest, which is straightforward to calculate. This is one of the reasons some buyers choose variable: the cost of refinancing mid-term is much more predictable than on a closed fixed mortgage.
Should I use a mortgage broker or go directly to my bank to refinance?
A mortgage broker has access to multiple lenders and can often find better rates than a single bank. They also understand which lenders are most competitive for your specific situation. Going directly to your bank is faster and simpler but may not get you the best rate. For most homeowners, speaking to a broker first is worth the time.
