Discharging Your Mortgage When Selling a Home in Ontario

Most Ontario homeowners carry a mortgage right up until they sell. That mortgage doesn't disappear the moment a buyer signs a purchase agreement — it needs to be formally paid out and discharged from title before clean ownership can transfer. For many sellers, this process is invisible: your lawyer handles it on closing day. But understanding what's happening can save you from surprises, especially when prepayment penalties enter the picture.

Discharging a mortgage when selling a home in Ontario involves more than sending your lender a cheque. It means obtaining a formal payout statement, accounting for interest and penalties to the exact closing date, and registering a discharge on title — sometimes weeks after the sale closes.

What Is a Mortgage Discharge?

A mortgage in Ontario is registered on title to your property as a charge. It gives your lender a legal interest in the property as security for your loan. When you sell, that charge must be removed — discharged — so the buyer receives clear title.

The discharge is a two-step process. First, the mortgage is paid out in full on closing day. Second, the lender registers a formal discharge document at the land registry office, confirming the charge has been removed. These two events don't always happen simultaneously, which matters more than most sellers realize.

The Payout Statement (Discharge Statement)

Before your lawyer can close the sale, they need to know the exact amount required to pay off your mortgage. That figure comes from a payout statement (sometimes called a discharge statement), which your lender prepares on request.

A payout statement typically sets out:

• Principal balance — the amount still owing on the loan
• Per diem interest — the daily interest accruing, so the statement can be updated to your exact closing date
• Prepayment penalty (if applicable) — the lender's charge for breaking the mortgage early
• Administration fees — charges for preparing the statement and processing the payout
• Discharge registration fee — what the lender will charge to register the discharge document after closing

Your lawyer will request this statement early in the transaction and confirm the numbers are current just before closing. Even a one-day error in the closing date can change the final payout figure, so accuracy matters.

Prepayment Penalties: The Biggest Surprise for Sellers

For sellers breaking a closed mortgage mid-term, prepayment penalties can run into thousands of dollars. Understanding how your lender calculates the penalty is essential before you commit to a sale.

Open vs. Closed Mortgages

An open mortgage allows you to pay out the balance at any time without penalty. If you have one, selling is straightforward — you simply pay the outstanding balance plus any small administration fees.

A closed mortgage is different. Closed mortgages come with restrictions on early repayment. If you sell before your term ends, your lender will typically charge a prepayment penalty.

How Penalties Are Calculated

Most lenders use one of two methods, and the difference can be dramatic:

Three months' interest is the simpler calculation. The lender takes three months of interest on your outstanding balance at your contract rate. For a typical mortgage, this might run a few thousand dollars.

Interest Rate Differential (IRD) is the more expensive method. The IRD is the difference between your contract interest rate and the rate the lender could get by re-lending the money today (often based on their posted rate for the remaining term). When current rates are significantly lower than your contract rate, the IRD penalty can be substantially higher than three months' interest — sometimes tens of thousands of dollars on a larger mortgage.

Which method applies depends on your mortgage contract. Variable-rate mortgages typically use the three-month interest method. Fixed-rate mortgages often use IRD, though the exact formula varies by lender. Always request a penalty calculation from your lender as of writing, since rates and calculations change — verify the current figure before accepting an offer.

Collateral Charge Mortgages

Some lenders register mortgages as collateral charges rather than standard charges. A collateral charge is typically registered for an amount higher than your actual loan — giving the lender flexibility to advance additional funds without re-registering. Collateral charges can only be discharged, not transferred or assigned to a new lender. The practical impact for sellers is usually minimal, but it's worth flagging to your lawyer, as the discharge process may differ slightly.

Your Lawyer's Role on Closing Day

On closing day, your real estate lawyer acts as the fulcrum of the transaction. Among their many tasks, they:

1. Obtain and verify the final payout statement updated to the closing date
2. Collect sale proceeds from the buyer's lawyer via electronic funds transfer
3. Direct the payout to your lender out of those proceeds
4. Confirm receipt with the lender so the discharge process can begin
5. Account for the penalty and all fees in the final Statement of Adjustments you review before signing

The lender then has a defined period to register the formal discharge document at the land registry. In practice, discharge registration can take several weeks after closing. This is normal — your lawyer retains a holdback or undertaking to ensure the lender registers promptly.

What Happens If the Discharge Isn't Registered?

If your lender fails to register the discharge in a reasonable time, it can cloud the buyer's title and create complications for any mortgage the buyer is placing on the property. Your lawyer will follow up with the lender, and if necessary, can take steps to compel registration.

From your perspective as the seller, the obligation effectively ends once the mortgage is paid out and your lawyer holds the lender's written undertaking to discharge. The follow-through is your lawyer's job.
