Key Takeaway

Refinancing your Canadian mortgage means breaking your existing mortgage contract before the term ends to secure a new mortgage, often with different terms or a new lender. It typically makes sense when you can secure a significantly lower interest rate, need to access home equity, want to consolidate high-interest debt, or need to change your mortgage structure. However, refinancing usually involves prepayment penalties and closing costs, so you need to calculate whether the long-term savings outweigh the upfront expenses.

What Refinancing Means in Canada

Refinancing your mortgage in Canada is different from renewing it. When you refinance, you break your current mortgage contract before the term ends and take out a new mortgage, either with your existing lender or a new one. This is distinct from a renewal, which happens at the end of your term when you renegotiate without penalties.

According to the Financial Consumer Agency of Canada, refinancing gives you the opportunity to renegotiate your rate, change your amortization period, access equity, or switch between fixed and variable products (FCAC, 2026). Because you are breaking your existing contract, you will face prepayment penalties, which can be substantial depending on your mortgage type and how much time remains on your term.

6 Steps to Refinance Your Canadian Mortgage

1. Determine Why You Want to Refinance

Start by identifying your specific goal. Common reasons Canadian homeowners refinance include securing a lower interest rate (especially if rates have dropped significantly since you locked in), accessing home equity for renovations or other expenses, consolidating high-interest debt into your mortgage, or switching from a variable-rate to a fixed-rate mortgage for payment stability.

Your reason will shape which mortgage product you choose and whether refinancing makes financial sense given the costs involved.

2. Calculate Your Prepayment Penalty

The biggest cost of refinancing is typically the prepayment penalty for breaking your current mortgage. For variable-rate mortgages, the penalty is usually three months of interest. For fixed-rate mortgages, lenders charge the greater of three months of interest or the interest rate differential (IRD), which compensates the lender for the interest they lose when you break the contract early.

The IRD calculation can result in penalties of C$10,000 to C$30,000 or more, depending on your remaining balance, how much time is left on your term, and the difference between your current rate and today’s rates. Contact your lender for an exact penalty calculation before proceeding.

3. Check How Much Equity You Can Access

In Canada, you can refinance up to 80 per cent of your home’s current appraised value. If your home is worth C$500,000 and you owe C$300,000, you could refinance for up to C$400,000 (80 per cent of C$500,000), giving you access to C$100,000 in equity minus closing costs.

You will need a current appraisal to confirm your home’s value, which typically costs C$300 to C$500. Keep in mind that accessing equity increases your mortgage balance and your monthly payments.

4. Understand the OSFI Stress Test Requirement

All mortgage refinances in Canada must meet the federally mandated mortgage stress test established by the Office of the Superintendent of Financial Institutions (OSFI). You must qualify at the higher of your contract rate plus two percentage points or the OSFI qualifying rate (currently 5.25 per cent as of July 2026).

This means even if a lender offers you a 3.5 per cent rate, you must prove you can afford payments calculated at 5.5 per cent (OSFI, 2026). If your income has decreased or your debt has increased since your original mortgage, you may not qualify to refinance for the amount you want.

5. Shop Around and Compare Offers

Do not simply refinance with your current lender. Mortgage brokers can access rates from multiple lenders, including banks, credit unions, and private lenders. Rate differences of even 0.25 per cent can save you thousands of dollars over the life of your mortgage.

Compare not just rates but also prepayment privileges, portability options, and penalties for future breaks. Some lenders offer cashback incentives or will cover your legal fees and appraisal costs, which can offset part of your penalty for leaving your current lender.

6. Factor in All Closing Costs

Beyond the prepayment penalty, refinancing involves legal fees (C$800 to C$1,500), appraisal fees (C$300 to C$500), title insurance, and potentially a mortgage discharge fee from your current lender (C$200 to C$400). If you are switching lenders, these costs add up.

Create a break-even calculation: divide your total upfront costs by your monthly savings to determine how many months it will take to recoup the expense. If you plan to move or refinance again before breaking even, it may not be worth it.

When Refinancing Makes Sense

Refinancing typically makes financial sense in these situations:

Rate savings: If current rates are at least 0.5 to 1 percentage point lower than your existing rate and you have several years left on your amortization, the long-term savings may justify the penalty.

Debt consolidation: If you are carrying high-interest debt (credit cards at 19 per cent or more, personal loans, lines of credit), consolidating it into your mortgage at 3 to 5 per cent can reduce your total interest costs significantly. However, you are securing unsecured debt against your home, so this strategy only works if you address the spending habits that created the debt.

Accessing equity for value-adding renovations: Using equity to fund renovations that increase your home’s value (kitchen, bathrooms, adding square footage) can be a sound investment, especially if the alternative is a higher-interest home equity line of credit or personal loan.

Switching mortgage structure: Moving from variable to fixed (or vice versa) to match your risk tolerance or financial situation can provide peace of mind or payment flexibility, though this alone rarely justifies a large prepayment penalty.

When to Wait

Refinancing may not make sense if you are close to your renewal date (within six months), since you can renegotiate penalty-free then. It also may not be worth it if your prepayment penalty is very high relative to your potential savings, if you plan to sell your home soon, or if you cannot pass the stress test with your current income and debt levels.

According to the Canada Mortgage and Housing Corporation, homeowners should carefully weigh the immediate costs against long-term benefits and consider whether a simple renewal or porting your mortgage to a new property might better serve your needs (CMHC, 2026).

Next Steps

Request a penalty calculation from your current lender, get a current appraisal if needed, and speak with a licensed mortgage broker to compare your refinancing options. A broker can help you run the numbers to determine whether refinancing will save you money over your remaining amortization period and which lender offers the best combination of rate, terms, and prepayment flexibility for your situation.
