How long should my mortgage term be if I might move? (Ontario)

If you might move within a few years, many Ontario borrowers choose a term that ends around the move, or a mortgage they can port or break for less. Leaving a fixed term early usually costs the higher of three months' interest or the interest rate differential. A shorter term means renewing sooner at whatever rates are then on offer, a longer one risks a penalty if you move first, and how sure you are of the timing decides which risk is easier to carry.

Why the term matters when you might move

Your term is the length of your mortgage contract. Your amortization is the time it would take to pay off the whole loan. At the end of a term there is no prepayment penalty: you can renew, switch lenders or pay the mortgage off. Paying the mortgage off before the end is a prepayment, and on a fixed mortgage the penalty is usually the higher of three months' interest or the interest rate differential (IRD), and your contract governs (source: Financial Consumer Agency of Canada, checked October 2026).

Selling the home does not end the contract. Unless the mortgage moves with you, the sale pays the mortgage off, and the penalty applies.

Four ways to plan for a move

Match the term to the plan. If you expect to move in about three years, a three-year term ends close to then, and paying off at maturity costs no penalty. The trade-off is renewing sooner, and because lenders price each term separately, the shorter term may cost more or less than the five-year one when you sign.
Choose a mortgage you can port. Porting moves your mortgage to a new home, within the lender's time limits, and the rules depend on the lender. Ask how many days you have between the sale and the purchase, and whether you can add money for a more expensive home.
Consider a variable rate. On a variable-rate mortgage the penalty is commonly three months' interest, though the contract governs. The payment or the time to pay off can change with rates; fixed or variable covers that trade-off.
Use an open mortgage for a short, certain stay. An open mortgage can be paid off at any time without a penalty. An open mortgage is generally priced higher, so it tends to suit a stay measured in months.

If you port a CMHC-insured mortgage, the insurance can move too, with no extra premium when the new loan is no larger than the balance owing and the amortization and loan-to-value are no larger than before. If the loan increases, CMHC charges an additional premium, with a credit for the premium already paid that shrinks over the first two years (source: CMHC, checked October 2026). Other insurers set their own rules.

If you expect to move in about three years

Illustrative, not a quote. On a $500,000 mortgage over 25 years, selling in year three of a five-year fixed term leaves two years to break. In our worked example, the penalty at that point was about $5,200 where it came to three months' interest. The penalty was about $9,300 where the IRD was calculated from posted rates.

With a three-year term that ends as you sell, there is no penalty. If the move slips a year, you renew for a term that fits the new timing, at the rates then on offer. If you stay put after all, the cost of the shorter term is renewing two years earlier than a five-year borrower would.

Terms longer than five years have one more rule. Under section 10 of the federal Interest Act, once five years have passed you can pay off with no more than three months' further interest. The rule does not apply to mortgages given by a corporation (source: Justice Laws, current to September 30, 2026). A lawyer can confirm how the rule applies to your mortgage.

Common follow-up questions

Can I avoid the penalty if I sell?

Usually by porting, where the lender allows it and you buy within its time limit. Otherwise the penalty generally applies to a closed mortgage paid off early. Ask the lender for a written penalty statement for your expected sale date; what it costs to break a mortgage explains the calculation.

What if I buy my next home before I sell?

If you buy first, the two closings may not line up. Bridge financing is commonly short, often a few months, and generally needs a firm sale on your current home. Costs and limits vary by lender. See buying before you sell.

Does a shorter term cost more?

Not necessarily. Lenders price each term on its own, and the gap between terms changes over time. Sometimes the shorter term has the lower rate, and sometimes the higher. Compare offers for both lengths on the same day, and add the penalty the shorter term would avoid.
