Summary: You do not have to pay off your mortgage before selling. On closing day, your lawyer uses the sale proceeds to pay out the mortgage and registers the discharge, then sends you the net proceeds. What you decide about the loan itself, whether to port it to your next home, break it and pay a penalty, or let it end at term, is separate, and worth sorting out early.
Most homeowners in Ontario sell with a mortgage still on the property, and the process is routine. The parts that catch people off guard are the prepayment penalty for breaking a fixed mortgage early and what happens if the sale price does not cover the balance. Here is how it works, from the payout statement to the discharge.
Can you sell a house before the mortgage is paid off?
Yes, and it is the norm. The outstanding mortgage does not block a sale; it simply has to be paid out of the proceeds when the deal closes. Until closing day, the mortgage stays active and you keep making your regular payments on time, because you still own the home. On closing, the loan is paid off and cleared from title as part of the transaction.
The key early step is telling your lawyer about every loan secured against the property. That includes not just your first mortgage but any secured line of credit. A home equity line of credit registered against the home has to be paid out and closed to clear title, the same as a mortgage.
How does the mortgage get paid off at closing?
Your lawyer runs the payout behind the scenes. The sequence looks like this:
Your lawyer requests a payout statement from your lender, which sets out the exact amount to clear the mortgage on the closing date: principal, accrued interest, any discharge fee, and any prepayment penalty.
On closing day, the funds are exchanged with the buyer's lawyer, and your lawyer uses the sale proceeds to pay the lender the full payout amount.
The discharge is registered. Once the lender confirms payment, your lawyer registers the discharge to remove the mortgage from the property's title.
You receive the net proceeds (the sale price, less the mortgage payout, closing costs, and adjustments) by the method you chose at signing.
Because the payout statement drives the closing math, requesting it early matters. Our guide to your sale closing walks through where this fits in the wider process.
Port, break, or pay off: what happens to the loan itself?
Paying out the mortgage on this property is separate from what happens to your borrowing going forward. You generally have three paths:
Port it. If your lender allows portability and you requalify, you can carry your existing rate and terms to your next home, which avoids a prepayment penalty. Porting usually requires your sale and purchase to line up within your lender's window, often somewhere around 30 to 90 days.
Break it. If you are not porting, ending a fixed-term mortgage early triggers a prepayment penalty. Per the Financial Consumer Agency of Canada, this is typically the greater of three months' interest or an interest rate differential (IRD) calculation, and it is usually higher on a fixed-rate mortgage.
Let it end at term. If your term happens to be maturing, you can pay the balance off on closing without a prepayment penalty.
Ask your lender for the penalty figure in writing before you firm up plans, because on a fixed mortgage an IRD penalty can be substantial and it changes the math on your net proceeds.
What if you owe more than the house sells for?
If your sale price will not cover the mortgage payout plus your selling costs, you are in a negative-equity position, and the shortfall is yours to cover. Title cannot be cleared for the buyer until the mortgage is paid in full, so you either bring the difference to closing from other funds or, in a genuine shortfall, get your lender's consent to the arrangement in advance. This is uncommon in a normal market, but it is worth checking your numbers early rather than discovering a gap days before closing. Map your costs of selling your home against your expected price so there are no surprises.
Port vs break vs pay off at term
The three routes for the loan itself compare like this:
Port the mortgage | Break the mortgage | Pay off at term |
Carry your rate and terms to the new home | End the mortgage early and repay in full | Repay in full as the term matures |
No prepayment penalty if you qualify | Prepayment penalty applies | No prepayment penalty |
Sale and purchase must align in a set window | Available whether or not you rebuy | Timing depends on your maturity date |
Best when your rate beats today's | Best when you are not rebuying, or porting is not offered | Best when your term is ending anyway |
In short, selling with a mortgage is routine; the decision that actually costs money is whether you port, break, or time the payout to your term.
Frequently asked questions
Do I have to pay off my mortgage before I list my house?
No. You can list and sell with a mortgage on title. It is paid out of the sale proceeds at closing, and your lawyer registers the discharge afterward.
Do I keep making mortgage payments while my house is for sale?
Yes. You still own the home until closing, so keep paying on schedule. The final payout is calculated to the closing date and settled then.
Will I pay a penalty for paying off my mortgage when I sell?
If you break a fixed-term mortgage early, usually yes — typically the greater of three months' interest or an interest rate differential. Porting the mortgage or paying it off at term avoids the penalty. Ask your lender for the exact figure.
What happens to my HELOC when I sell?
A home equity line of credit secured against the property must also be paid out and closed so title can be cleared. Tell your lawyer about it early, alongside your mortgage.
What if my home sells for less than I owe?
You have to cover the shortfall so the mortgage can be paid in full and discharged. In a true shortfall you would need your lender's agreement to the arrangement before closing.
