Porting Your Mortgage When You Sell in Ottawa and Buy in Kemptville or Brockville

Often, yes. If your mortgage is portable and your lender approves you and the new property, you can take your existing rate, terms and conditions with you from your Ottawa home to the one you buy in Kemptville, Brockville or elsewhere along the corridor, and avoid the prepayment penalty for breaking the term early.

The catch on this particular move is size. Corridor homes often cost less than the Ottawa home you are leaving, and the Financial Consumer Agency of Canada warns that if your new home costs less than the amount of your mortgage, you may still pay a penalty. Call your lender before you list, not after you have an offer.

What porting a mortgage actually means

Most homeowners have a closed mortgage with a set term. Selling your home pays the mortgage off early, and paying a closed mortgage off early normally triggers a prepayment penalty.

A portable mortgage is the way around that. The FCAC describes it simply: if you sell your home to buy another one, a portable mortgage allows you to transfer your existing mortgage. In practice that means you keep the rate, the remaining term and the conditions you already have, and they move to the new property.

Two things are easy to miss. Not every mortgage is portable, and the FCAC's advice is to check with your lender whether yours is eligible. And porting is not automatic. The lender is lending against a new property, so expect it to look at that property, and at you, before it says yes.

Why this matters more when you move from Ottawa to the corridor

Plenty of people moving from Ottawa to Kemptville, Brockville, Prescott or the townships around them are doing it partly for the price difference. They sell in the city, buy for less down the 416 or along the river, and use the gap to carry a smaller mortgage or none at all. We went through that equity math in the Ottawa-to-Brockville price gap.

That plan and porting can pull against each other. Porting works most cleanly when you are carrying the same mortgage to a similar or more expensive home. When you want to borrow less on a cheaper home, part of what you owe today is being paid off early, and the FCAC is explicit that if your new home costs less than the amount of your mortgage, you may pay a prepayment penalty.

So the question is rarely just "can I port?" It is "what happens to the part of my mortgage I no longer need?" Only your lender can answer that, and the answer can change which option makes sense.

Your realistic options

Option When it tends to fit What to watch
Port the mortgage as it is Your new purchase needs roughly the same mortgage you have now Keeps your current rate and terms and normally avoids the prepayment penalty, if the lender approves the move
Port a smaller balance Your Ottawa sale leaves you with enough equity to borrow less on the corridor home FCAC warns that if the new home costs less than the amount of your mortgage, you may pay a prepayment penalty. Ask how the lender treats the part you no longer need
Port and borrow more The next home needs a bigger mortgage than you have now Some lenders allow it. Ask in writing how the rate on the larger amount would be set before you count on it
Break the mortgage You are switching lenders, the mortgage is not portable, or the timing will not line up You normally pay a prepayment penalty, and the FCAC notes it can cost thousands of dollars

There is no option here that is right for everyone. A smaller penalty on a modest balance might be worth paying to get a cleaner mortgage on the new home. A large penalty on a big fixed-rate balance might make porting, even with some penalty on the difference, the better trade. You need the actual figures to compare.

How the penalty is usually worked out

If you do end up breaking the mortgage, or breaking part of it, it helps to know what drives the number. The FCAC says the penalty is typically the higher of two amounts:

  • three months' interest on what you still owe, or
  • the interest rate differential, often called the IRD

The IRD is usually what applies when the rate on your mortgage is higher than today's rate and you signed your contract less than five years ago. Lenders calculate it using rates that can include the posted rate when you signed, your discounted rate, and the current posted rate for a similar term. The method varies from lender to lender, which is exactly why a written payout quote matters more than any online calculator. Our line-by-line look at what it costs to sell covers where this sits alongside commission, legal fees and the rest.

The FCAC also suggests a few ways to soften it: use your annual prepayment privileges, consider a lump-sum prepayment before you break the contract, and if your term is close to ending, think about whether waiting makes sense. Some lenders restrict prepayments when you are close to the date you break the contract, so ask before you plan around it.

The timing between two closings

A port connects two transactions: the sale in Ottawa and the purchase in the corridor. How much time can pass between them is set by your lender and your contract, not by any standard rule. Ask what your window is before you agree to closing dates on either side.

If your purchase closes before your sale, that is a different problem, usually handled with bridge financing rather than a port. We covered that sequence in sell first or buy first.

The practical move is to get the lender's porting conditions first, then negotiate both closing dates around them. It is much easier to ask for a closing date that fits than to fix one after the agreement is firm.

Questions to ask your lender before you list

  • Is my mortgage portable, and is there anything in my contract that limits it?
  • How much time can pass between my sale closing and my purchase closing for the port to still work?
  • If I port a smaller balance than I owe today, is there a penalty on the difference, and how would it be calculated?
  • If I need to borrow more, can I add to the ported amount, and how would the rate on the total be set?
  • What would my penalty be if I broke the mortgage on my expected closing date instead? Please put the figure in writing.
  • What will you need from me to approve the new property, and are there any property types you treat differently?
  • How much of my prepayment privilege is still unused this year, and is there any restriction on using it close to the date I sell?

Before you count on porting

A few things can change the answer even when your mortgage is portable on paper:

  • Expect your situation to be reviewed. Ask the lender what it will look at now, since it is lending against a new property. A change in income or debts since you signed can matter.
  • The new property has to be acceptable to the lender. If you are moving to a rural home, an older house or something with acreage, ask early whether that changes anything.
  • Porting keeps you with your current lender. You are taking your existing mortgage with you. If you would rather move to another lender, compare that against the penalty you would pay to leave.

Common follow-up questions

My term ends in a few months. Should I just wait?

It can be worth comparing. The FCAC suggests considering waiting until the end of your term if your penalty would be large, because at that point you can pay the mortgage off without a penalty. Weigh that against what a later sale date means for your move.

Could the buyer of my Ottawa home take over my mortgage instead?

That is an assumable mortgage, which is a different arrangement. The FCAC notes the assumable option is typically available on most fixed-rate mortgages, but it also warns that in some provinces the seller may remain personally liable for the assumed mortgage after the sale. Talk to your lender and your lawyer before offering it.

Do I need a mortgage broker or my bank for this?

The port itself happens with the lender that holds your mortgage now. A broker can still be useful for comparing a port against a new mortgage elsewhere, penalty included, so you are choosing between real numbers.
