Key Takeaway: Open mortgages let you prepay or refinance anytime without penalty but carry higher interest rates, while closed mortgages lock you in for the term with limited prepayment privileges and lower rates. Choose open if you expect a windfall or plan to sell soon; choose closed if you want the lowest rate and can work within standard prepayment limits (typically 10 to 20 per cent annually).

When you shop for a mortgage in Canada, one of the first decisions is whether to take an open or a closed mortgage. The difference comes down to flexibility versus cost. An open mortgage gives you complete freedom to prepay or break the contract without a penalty, but you pay a premium in the form of a higher interest rate. A closed mortgage restricts your prepayment and early-exit options but rewards you with the lowest available rate for the term.

Most Canadian borrowers choose a closed mortgage because the rate savings over a typical five-year term outweigh the prepayment restrictions, especially when the lender offers reasonable prepayment privileges. But an open mortgage can make sense if your situation is short-term or if you know a large lump sum is coming and you want to pay down or retire the loan quickly.

This checklist walks you through the factors that matter when choosing between the two, so you can match the mortgage type to your goals, timeline, and cash-flow expectations.

Checklist: When an Open Mortgage Fits

Use this section if you value maximum flexibility and are willing to pay a higher rate for it.

  • You plan to sell the property within 12 months. An open mortgage lets you pay off the loan when the sale closes, with no prepayment penalty.
  • You expect a large lump sum soon (inheritance, bonus, sale of another property, or investment maturity) and want to put it directly against the mortgage principal without restriction.
  • You are refinancing in the near term. If you know you will consolidate debt, access equity, or switch to a longer-term product within a few months, an open mortgage avoids the penalty for breaking a closed term early.
  • You prefer a bridge or short-term solution. Open mortgages are often used as temporary financing while you arrange permanent financing or wait for another transaction to settle.
  • The rate premium is acceptable given your timeline. Open mortgage rates are typically one to three percentage points higher than closed rates, according to the Financial Consumer Agency of Canada (FCAC, 2026). If your holding period is short, the total extra interest may be less than the penalty you would pay to break a closed mortgage early.

Use this section if you want the lowest rate and can live within the standard prepayment rules for the term.

  • You plan to stay in the property for the full mortgage term (commonly one to five years) or longer, and you have no plans to sell or refinance before renewal.
  • You want the lowest possible interest rate. Closed mortgages offer the best rates because the lender locks in your business for the term, as explained in foundational texts such as Principles of Finance (OpenStax, 2022).
  • The standard prepayment privileges meet your needs. Most closed mortgages in Canada allow you to prepay 10 to 20 per cent of the original principal each year, and to increase your regular payment by 10 to 20 per cent annually, without penalty. Check your lender’s specific terms.
  • You do not expect a windfall or major financial change during the term. If your income and expenses are stable and predictable, the prepayment limits are usually enough to let you pay down the mortgage faster without triggering a penalty.
  • You understand the prepayment penalty if you break the term early. Closed mortgages charge a penalty if you pay off the loan before the end of the term. The penalty is typically the greater of three months’ interest or the interest rate differential (IRD), which can be substantial if rates have fallen since you locked in. The Canada Mortgage and Housing Corporation (CMHC, 2026) provides educational resources on how these penalties are calculated.

Factors to Evaluate Before Deciding

Work through these questions to clarify which mortgage type aligns with your situation.

  • What is your expected time horizon in the property? Less than one year favours open; one year or longer favours closed.
  • How likely are you to receive or generate a large lump sum during the term? If very likely and you want to apply it all at once, open is safer. If unlikely or you can spread prepayments over time within the annual limit, closed works.
  • What is the rate difference between open and closed for the term you want? Request quotes for both and calculate the total interest cost over your expected holding period. Compare that cost to the estimated penalty for breaking a closed mortgage early, if that scenario applies.
  • Does your lender offer competitive prepayment privileges on the closed product? Some lenders allow higher annual prepayment caps or more flexible lump-sum windows. Review the fine print.
  • Are you refinancing or consolidating debt? If the goal is to roll other high-interest debt into the mortgage, a closed mortgage at a lower rate usually saves more in total interest, even with the prepayment restrictions, provided you can stay in the term.
  • Will you qualify under the OSFI mortgage stress test at the higher open rate? The stress test requires you to qualify at the greater of your contract rate plus two percentage points or the Bank of Canada five-year benchmark rate. An open mortgage’s higher rate may reduce your borrowing capacity.

How to Compare Your Options

  1. Request a written rate quote for both an open and a closed mortgage from your lender or mortgage broker, for the same term length.
  2. Calculate the monthly payment and total interest cost for each option over the period you expect to hold the mortgage.
  3. If you think you might break the term early, ask the lender for an estimate of the prepayment penalty under the closed mortgage, based on current and projected rate scenarios.
  4. Confirm the prepayment privileges (annual lump-sum limit, payment increase limit, frequency options) for the closed mortgage, and decide whether they give you enough flexibility for your goals.
  5. Choose the option that delivers the lowest total cost and acceptable flexibility for your timeline and financial situation, as recommended by Ratehub.ca (Ratehub, 2026).

Conclusion

Open mortgages suit short timelines and unpredictable cash flow; closed mortgages suit stable plans and rate-conscious borrowers. Most Canadians opt for a closed mortgage and use the prepayment privileges to accelerate paydown within the annual caps. If you expect to sell, refinance, or receive a windfall in the next year, an open mortgage avoids the penalty and gives you full control. Review your lender’s specific terms, run the numbers for both options, and confirm your choice with a licensed mortgage broker who can verify current rates and qualifying rules for your province and situation.
