What is a Mortgage Refinance in Canada?

Before diving into the specifics of mortgage refinance calculators, it’s essential to understand what a mortgage refinance actually entails in the Canadian context. Simply put, a mortgage refinance is the process of replacing your existing home loan with a new one, often with different terms or a lower interest rate.

Key Points:

  • A refinance involves paying off your existing mortgage with a new loan
  • The new mortgage can be with your current lender or a different one
  • Refinancing offers opportunities to change your loan terms, interest rate, and loan amount
  • In Canada, you can typically refinance up to 80% of your home’s appraised value

Why Consider a Mortgage Refinance in Canada?

There are several reasons why Canadian homeowners might consider refinancing their mortgage:

  1. Lower interest rates: If market rates have dropped since you obtained your original mortgage, refinancing could lead to significant savings.
  2. Improved cash flow: Refinancing can potentially lower your monthly payments, freeing up cash for other expenses.
  3. Debt consolidation: You can use a refinance to pay off high-interest debts, consolidating them into your mortgage at a lower rate.
  4. Home improvements: Refinancing can provide funds for renovations or remodeling projects.
  5. Investment opportunities: Some homeowners refinance to access equity for investment purposes.
  6. Changing mortgage terms: You might want to switch from a variable to a fixed-rate mortgage, or vice versa.

The Role of a Mortgage Refinance Calculator in Canada

A mortgage refinance calculator is an invaluable tool that helps Canadian homeowners determine whether refinancing makes financial sense. By inputting various data points, you can quickly assess the potential benefits and costs associated with refinancing your mortgage.

Key Functions of a Canadian Mortgage Refinance Calculator:

  • Estimate monthly payments under different scenarios
  • Calculate potential savings over the life of the loan
  • Determine the break-even point for refinancing costs

  • Account for Canadian-specific factors like prepayment privileges and penalties

How to Use a Canadian Mortgage Refinance Calculator

To get the most out of a mortgage refinance calculator tailored for the Canadian market, follow these steps:

  1. Gather your current mortgage information:
    • Current loan balance
    • Interest rate
    • Monthly payment
    • Remaining loan term
    • Prepayment privileges and penalties
  2. Research current market rates: Look for competitive rates from various Canadian lenders or consult with a mortgage broker.
  3. Estimate refinancing costs: These may include:
    • Application fees
    • Appraisal fees
    • Legal fees

Interpreting Canadian Mortgage Refinance Calculator Results

Understanding the output of a mortgage refinance calculator is crucial for making an informed decision in the Canadian market. Here are some key metrics to consider:

Monthly Savings

This represents the difference between your current monthly payment and the projected payment after refinancing. While a lower payment can be attractive, it’s important to consider the long-term implications and how it fits into your overall financial plan.

Total Interest Savings

This figure shows how much less you’ll pay in interest over the life of the loan if you refinance. Substantial interest savings can make refinancing worthwhile, even if there are upfront costs.

Break-Even Point

This is the time it takes for your monthly savings to offset the costs of refinancing. If you plan to stay in your home beyond this point, refinancing may be beneficial.

Break-Even Point = Total Refinancing Costs / Monthly Savings

Long-Term Savings

Consider the total amount you’ll save over the entire loan term. This can be significant, especially if you’re reducing your interest rate or shortening your loan term.

Canadian Mortgage Terms and Conditions to Consider

When refinancing in Canada, it’s important to understand the specific terms and conditions that may affect your mortgage:

Prepayment Privileges

Many Canadian mortgages offer prepayment privileges, allowing you to make extra payments without penalty. These can include:

  • Annual lump sum payments (typically 10-20% of the original mortgage amount)
  • Increasing your regular payments by a certain percentage

Prepayment Penalties

If you’re breaking your current mortgage term to refinance, you may face prepayment penalties. These can be significant and are typically calculated as:

  • For variable-rate mortgages: 3 months’ interest
  • For fixed-rate mortgages: The greater of 3 months’ interest or the Interest Rate Differential (IRD)


Some Canadian mortgages are portable, meaning you can transfer them to a new property if you move. This feature can be valuable if you refinance and then decide to relocate before your term ends.


An assumable mortgage allows a buyer to take over your mortgage when you sell your home. This can be advantageous if interest rates have risen since you refinanced.

Pros and Cons of Refinancing in Canada

While a mortgage refinance calculator can provide valuable insights, it’s important to weigh the pros and cons of refinancing in the Canadian context:


  • Potential for lower monthly payments
  • Opportunity to save on interest over the life of the loan
  • Ability to tap into home equity for other financial goals
  • Option to switch from an adjustable-rate to a fixed-rate mortgage (or vice versa)
  • Consolidation of high-interest debts


  • Upfront costs associated with refinancing
  • Potential for a longer loan term, which could result in paying more interest overall
  • Risk of prepayment penalties on your current mortgage
  • Temptation to cash out equity for non-essential expenses
  • Possible loss of beneficial terms from your original mortgage

Refinance vs. Home Equity Line of Credit (HELOC) in Canada

When considering accessing your home’s equity in Canada, it’s worth comparing a refinance to a Home Equity Line of Credit (HELOC):

Interest RateGenerally lowerUsually higher, variable
Funds AccessLump sumAs needed
RepaymentFixed monthly paymentsFlexible, interest-only options
Closing CostsTypically higherOften lower
Tax DeductibilityNot typically deductible for personal useMay be deductible for investment purposes
Maximum BorrowingUp to 80% of home valueUp to 65% of home value

Tips for a Successful Mortgage Refinance in Canada

To ensure you get the most out of your mortgage refinance in the Canadian market, consider these tips:

  1. Shop around: Don’t settle for the first offer. Compare rates and terms from multiple Canadian lenders.
  2. Check your credit score: A higher credit score can lead to better refinance terms. Take steps to improve your credit if necessary.
  3. Consider your long-term plans: If you’re planning to move in the near future, refinancing may not be worth the upfront costs.
  4. Look beyond the interest rate: Pay attention to fees, loan terms, and prepayment penalties specific to Canadian mortgages.
  5. Don’t cash out too much equity: Maintaining at least 20% equity can help you avoid CMHC insurance.
  6. Be cautious about extending your loan term: While a longer term can lower monthly payments, it may result in paying more interest over time.
  7. Prepare your documentation: Have your financial documents ready to streamline the application process.
  8. Understand the impact on your taxes: Unlike in the US, mortgage interest is generally not tax-deductible in Canada for personal residences.

Refinancing with Less-Than-Perfect Credit in Canada

If your credit score has declined since you obtained your original mortgage, refinancing may still be possible in Canada:

  • Explore alternative lenders: Some Canadian lenders specialize in working with borrowers who have less-than-perfect credit.
  • Consider a cash-out refinance: Using equity to pay off high-interest debts can improve your overall financial picture.
  • Work with a mortgage broker: They may have access to lenders specializing in less-than-perfect credit situations.
  • Improve your credit score: Even a small improvement can make a difference in your refinance terms.

The Canadian Mortgage Stress Test

When refinancing in Canada, you’ll need to pass the mortgage stress test, even if you’re staying with your current lender. This test ensures you can afford your mortgage payments if interest rates rise:

  • You must qualify at the higher of your contract rate plus 2% or the Bank of Canada’s five-year benchmark rate
  • This may affect how much you can borrow when refinancing

The Future of Mortgage Rates in Canada

While it’s impossible to predict future mortgage rates with certainty, several factors can influence the Canadian market:

  • Bank of Canada policies
  • Overall economic conditions
  • Inflation rates
  • Housing market trends
  • Global economic factors

Staying informed about these factors can help you time your refinance for maximum benefit in the Canadian market.

Government Programs and Refinancing in Canada

Several government programs in Canada can affect or assist with mortgage refinancing:

First-Time Home Buyer Incentive

While primarily for new homebuyers, this program can affect refinancing if you used it to purchase your home. You’ll need to repay the incentive when refinancing.

Home Buyers’ Plan (HBP)

If you withdrew funds from your RRSP under the HBP, remember that refinancing doesn’t affect your repayment obligations.

Green Home Program

Some lenders offer better rates or terms for energy-efficient homes. Consider this if you’re refinancing to fund energy-saving renovations.

Tax Implications of Refinancing in Canada

Unlike in the United States, mortgage interest on your principal residence is generally not tax-deductible in Canada. However, there are some tax considerations when refinancing:

  • If you use the funds for investment purposes, the interest may be tax-deductible
  • Rental property mortgages may have deductible interest
  • Consult with a tax professional to understand the implications for your specific situation

The Refinancing Process in Canada

Understanding the steps involved in refinancing can help you navigate the process more smoothly:

  1. Assess your current situation: Review your existing mortgage terms and financial goals.
  2. Research and compare options: Use mortgage refinance calculators and consult with lenders or brokers.
  3. Gather documentation: Prepare income verification, property information, and other required documents.
  4. Apply for the new mortgage: Submit your application to your chosen lender.
  5. Home appraisal: The lender will typically require a current appraisal of your property.
  6. Approval and underwriting: The lender reviews your application and makes a decision.
  7. Review and sign documents: Carefully read all terms and conditions before signing.
  8. Closing: Finalize the new mortgage, pay any required fees, and complete the refinance.

Conclusion: Is Refinancing Right for You in Canada?

Ultimately, the decision to refinance your mortgage depends on your individual financial situation and goals within the Canadian market. A mortgage refinance calculator can provide valuable insights, but it’s just one tool in the decision-making process.
