How to Break A Mortgage

by | October 15, 2026

Breaking a mortgage in Ontario, Canada, before the end of its term can lead to significant penalties. It’s important to understand these penalties and how they are calculated. Here are the key points to consider:

Types of Penalties

  • Fixed-Rate Mortgages:
    The penalty is typically the higher of three months’ interest, or the interest rate differential (IRD). The IRD is the difference between your current mortgage rate and the rate the lender can charge today for a mortgage term similar to your remaining term, multiplied by the remaining balance and term.
  • Variable-Rate Mortgages:
    The penalty is usually equivalent to three months’ interest on your current mortgage balance.

Interest Rate Differential (IRD)

  • IRD Calculation
    This can vary between lenders. It’s based on factors like your current interest rate, the current market rate for a similar term, and the remaining balance and duration of your mortgage.
  • Posted vs. Discounted Rates
    Some lenders calculate the IRD using their posted rates (which are typically higher) rather than the discounted rate you may be paying, which can significantly increase the penalty.

Three Months’ Interest

  • Simple Calculation:
    This is generally easier to calculate than the IRD. It’s simply three months of interest on your current mortgage balance at your current rate.

Other Fees

  • Administration Fees:
    Some lenders charge additional fees for discharging a mortgage early.
  • Reinvestment Fee:
    A fee that may be charged to cover the lender’s costs of reinvesting the funds when you pay off your mortgage early.

Porting Your Mortgage

  • Portability Option:
    If you’re moving to another property, some mortgages allow you to “port” your mortgage to the new property to avoid or reduce penalties.

Blend and Extend

  • Blending Rates:
    Some lenders offer an option to blend your current mortgage rate with the rate for a new term, which can reduce penalties.

Consult Your Mortgage Agreement

  • Review Terms and Conditions:
    Your mortgage agreement will outline the specific details of penalty calculations and any applicable fees.

Seek Professional Advice

  • Mortgage Agent:
    Give me a call to discuss and understand the implications of breaking your mortgage and to explore alternatives.

Consider the Timing

  • End of Term:
    If your term is almost over, it might be more cost-effective to wait until the term ends to avoid or minimize penalties.

Negotiate with Lenders

Negotiation: In some cases, you might be able to negotiate the penalty, especially if you are staying with the same lender but changing mortgage products.


Breaking a mortgage can be costly, and the penalties can vary significantly depending on your lender and the terms of your mortgage. It’s crucial to understand these penalties and consider them in your financial planning, especially if you’re contemplating selling your home, refinancing, or paying off your mortgage early. Always review your mortgage contract and consult with a financial professional to fully understand the implications of breaking your mortgage in Ontario.
