Most Canadian closed mortgages include prepayment privileges that let you pay down principal faster without breaking your term or triggering penalties. Typical privileges allow a 10 to 20 per cent lump-sum payment each year, plus the option to increase your regular payment by 10 to 20 per cent. Using these privileges strategically can cut years off your amortization and save tens of thousands of dollars in interest, even while you remain in your current term.

What Are Prepayment Privileges?

Prepayment privileges are built-in features of most closed mortgages in Canada that let you make extra payments toward your principal balance without incurring prepayment penalties. According to the Financial Consumer Agency of Canada, these privileges are outlined in your mortgage contract and vary by lender, but they typically include two main types: lump-sum payments and increased regular payments (FCAC, 2026).

A lump-sum prepayment privilege allows you to pay a set percentage of your original mortgage principal (commonly 10 to 20 per cent) once per calendar year or on each anniversary date, depending on your lender’s terms. An increased payment privilege lets you raise your regular mortgage payment by a set percentage (again, typically 10 to 20 per cent) without penalty, either permanently or temporarily.

Open mortgages allow unlimited prepayment at any time but charge higher interest rates. Closed mortgages lock in a lower rate in exchange for prepayment restrictions, though the prepayment privileges provide a middle ground.

How Prepayment Privileges Work in Canada

Canadian mortgages are structured around a term (the period your rate and conditions are locked in, commonly one to five years) and an amortization (the total time to pay off the loan, often 25 to 30 years). When you renew at the end of each term, you renegotiate your rate and can adjust your payment structure.

Prepayment privileges apply during your current term. Every dollar you prepay goes directly to principal, reducing the outstanding balance. Because mortgage interest is calculated on the remaining principal, a lower balance means less interest charged over the life of the loan. As foundational texts such as Principles of Finance explain, reducing principal early in the amortization has the greatest impact, since interest costs are front-loaded in a typical mortgage payment schedule.

The Canada Mortgage and Housing Corporation notes that even modest prepayments can materially shorten your amortization (CMHC, 2026). For example, increasing your monthly payment by 10 per cent on a 25-year amortization at 5 per cent interest can shave years off your payoff date and save significant interest.

Common Prepayment Privilege Structures

Lenders set their own prepayment terms, so the exact privileges vary. Major Canadian banks commonly offer:

  • Lump-sum privileges: 10 to 20 per cent of the original principal amount per year, paid on the anniversary date or within each calendar year.
  • Increased payment privileges: 10 to 20 per cent increase to your regular payment amount, either monthly or per payment period, without penalty.
  • Double-up payments: Some lenders allow you to double a regular payment at any time, with the extra amount applied to principal.

Prepayment privileges reset each term. If you do not use your full annual lump-sum allowance, it does not carry forward to the next year. Check your mortgage statement or contact your lender to confirm the exact privileges available under your current term.

Prepayment Penalties and Restrictions

Prepayments within your allowed privileges do not trigger penalties. Prepayments beyond those limits, or breaking your mortgage term early to refinance or pay off the full balance, typically incur a prepayment penalty. For closed mortgages, the penalty is the greater of three months’ interest or the interest rate differential (IRD), a calculation based on the difference between your contract rate and the current rate for the remaining term.

The IRD can be substantial when rates have fallen since you locked in. Prepayment privileges let you accelerate payoff without triggering this penalty, making them the most cost-effective way to reduce your mortgage balance during a term.

Provincial regulations govern mortgage contract terms, and the federal government requires lenders to disclose prepayment options clearly. Review your mortgage contract and confirm the specific privileges with your lender before making a prepayment.

Using a Calculator to Plan Your Prepayments

An extra mortgage payment calculator lets you model the impact of different prepayment strategies before you commit funds. You enter your current mortgage balance, interest rate, remaining amortization, and the amount and frequency of extra payments (lump sums, increased monthly payments, or both). The calculator shows how much interest you save and how many months or years you cut from your amortization.

This tool is especially valuable when deciding how to allocate a tax refund, work bonus, or other windfall. You can compare a single large lump-sum payment against spreading the same amount across increased monthly payments, or test different combinations to find the strategy that fits your cash flow and maximizes savings.

When to Consider Prepayments

Prepayment makes the most sense when:

  • You have stable cash flow and can afford extra payments without stretching your budget.
  • Your mortgage interest rate is higher than the after-tax return you would earn by investing the same funds elsewhere.
  • You are early in your amortization, when the interest portion of each payment is highest.
  • You are approaching retirement and want to reduce or eliminate housing costs before your income drops.

Prepayment may be less attractive if you carry higher-interest debt (such as credit card balances), lack an emergency fund, or can earn a higher guaranteed return through a registered savings vehicle like an RRSP or TFSA.

Practical Tips for Maximizing Prepayment Privileges

  • Confirm your privileges annually: Lender terms can change at renewal, and some privileges reset on the calendar year while others reset on your mortgage anniversary. Know your window.
  • Align lump sums with your cash flow: If you receive an annual bonus or tax refund, schedule your lump-sum prepayment shortly after to maximize the time the reduced principal saves interest.
  • Increase payments incrementally: If your budget allows, start with a small increase (5 per cent) and raise it further as your income grows or expenses decline.
  • Track your progress: Request an updated amortization schedule from your lender after making a prepayment to see the revised payoff date and total interest saved.

Final Thoughts

Prepayment privileges are one of the most underused tools available to Canadian mortgage holders. They let you reduce your principal, save on interest, and shorten your amortization without breaking your term or paying penalties. Whether you make a single lump-sum payment each year or increase your regular payments by 10 per cent, the cumulative effect over the life of your mortgage can be substantial. Use a calculator to model your options, confirm your lender’s specific terms, and choose a prepayment strategy that fits your financial goals and cash flow.
