How Power of Sale Works in Ontario — The Complete Guide

Power of sale is the most common method used by mortgage lenders in Ontario to recover money owed when a borrower defaults on their mortgage. It is a legal process — but unlike foreclosure (which is rare in Ontario) — it does not require the lender to go through a lengthy court process to take ownership of the property. Instead, the lender has the contractual right, embedded in virtually all Ontario mortgages, to sell the property on the borrower's behalf once the conditions for default have been met.

The term "power of sale" comes from the clause in the mortgage agreement itself — a provision that gives the lender the legal power to sell the mortgaged property if the borrower fails to meet their payment obligations. Most Ontario homeowners have this clause in their mortgage without being fully aware of it.

It is important to understand that power of sale does not mean you have lost your home. It means your lender has begun the legal process that could result in them selling your home if you do not take action. There are steps in that process, and at multiple points along the way, you have rights and options.

Foreclosure and power of sale are often confused, but they are fundamentally different processes with different outcomes for the homeowner.

In a foreclosure, the lender takes ownership of the property — the homeowner loses all equity and the lender becomes the new owner outright. Foreclosure requires a court order and is relatively rare in Ontario because most mortgage contracts include a power of sale clause, which gives lenders a faster alternative.

In a power of sale, the lender does not take ownership. Instead, they sell the property on the homeowner's behalf and recover what they're owed from the proceeds. Any money remaining after the mortgage debt, arrears, interest, and legal costs are paid belongs to the homeowner. This is a meaningful distinction — it means you may have equity to protect even in a power of sale situation.

Understanding the process is critical because it tells you where you have time to act.

Step 1: Default. You miss mortgage payments. Most mortgages define default as missing a specific number of payments (often three), though the terms vary by lender. Once default is established, the lender's right to act begins.

Step 2: Demand letter. The lender sends a formal demand for payment of the arrears. This is a legal notice, not just a collection call. You should consult a lawyer if you receive one.

Step 3: Notice of sale. After the demand period has passed — typically 15 days for commercial lenders, 35 days for residential mortgages under the Mortgages Act — the lender can issue a Notice of Sale. This formally notifies you that the lender intends to sell the property.

Step 4: Redemption period. Once the Notice of Sale is issued, you have a redemption period — for residential properties, this is generally 35 days — during which you can pay the full amount owing (arrears plus costs) and stop the process. This is your primary right during power of sale.

Step 5: Listing and sale. If you have not redeemed the mortgage by the end of the redemption period, the lender can list and sell the property. They are legally required to obtain fair market value — but their primary obligation is to recover their debt, not to maximise your equity.

Ontario homeowners have meaningful legal rights during the power of sale process. These rights exist specifically to protect you — knowing them is essential.

Right to redeem. At any point before the lender completes the sale, you have the right to pay out the full amount owing — the mortgage balance, arrears, interest, penalties, and legal costs — and reclaim your property. This right continues even after the Notice of Sale is issued.

Right to surplus proceeds. If the lender's sale generates more than what you owe (including all costs), you are entitled to the surplus. The lender cannot keep money beyond what they're owed.

Right to notice. The lender must follow specific legal notice requirements at each stage of the process. Failure to provide proper notice can invalidate their actions. A lawyer can review whether proper procedures have been followed in your case.

Right to sell privately. At any point before the lender completes their sale, you retain the right to sell the property yourself. This is often the most important right — because a private sale, managed properly, almost always generates a better outcome for the homeowner than a lender-driven sale.

This is the most important question for most homeowners in a power of sale situation — and it's one where many people assume the worst incorrectly.

Your equity is the difference between what your property is worth and what you owe on it. During a power of sale, that equity can be preserved — but only if you act.

In a lender-driven sale, the lender is legally required to obtain fair market value, but their costs come off the top: legal fees, realtor commissions (if they use an agent), carrying costs during the listing period, and any repairs they've made. After all of that comes off, and after the full mortgage balance and arrears are paid, whatever remains belongs to you.

In a private sale — where you sell the property directly before the lender completes their process — you control the price negotiation, the sale costs, and the timing. For most sellers, this results in more money in hand, even if the gross selling price is similar.

The math is straightforward: a lender-driven sale carries more costs, takes longer, and gives you zero control. A private direct sale is almost always a better financial outcome if you can arrange it before the lender's sale completes.

There are several ways to stop a power of sale in Ontario, depending on where you are in the process and what resources you have available.

Option 1: Pay the arrears. If you can bring your payments up to date and pay any associated penalties and costs before the end of the redemption period, the power of sale process stops. This is the simplest path, but requires the financial resources to catch up.

Option 2: Refinance. If you have equity, you may be able to refinance with a new lender — including a private lender — to pay out the existing mortgage and arrears. This can stop the power of sale and give you time to stabilise your finances.

Option 3: Sell privately. Selling the property to a buyer of your choice, at a fair market price, allows you to pay out the mortgage, recover your equity, and avoid the lender's sale process entirely. This option is available at any point before the lender completes their sale.

Option 4: Negotiate with the lender. Some lenders will agree to a payment arrangement or deferral, particularly if you can demonstrate that your financial difficulty is temporary. This is worth attempting — but get any agreement in writing and involve a lawyer.
