Power of Sale vs Foreclosure in Ontario: What Happens When a Mortgage Goes Into Default

Missing mortgage payments is stressful enough. Not understanding what happens next — and how fast — makes it worse. In Ontario, lenders have two main legal tools to enforce a mortgage after default: power of sale and foreclosure. Each follows a different legal process, comes with different consequences, and leaves the borrower in a different position. Knowing the difference gives you a clearer picture of your rights, your timeline, and your options.

What Is "Default"?

A mortgage default occurs when a borrower fails to meet an obligation under the mortgage contract. The most common default is missing principal and interest payments. Other defaults can include:

• Failing to maintain property insurance
• Failing to pay property taxes
• Breaching a term of the mortgage (for example, renting the property without lender consent, if prohibited)
• A second charge being registered without consent

Most mortgage contracts specify a number of days after which a missed payment constitutes a formal default — check your contract for the exact trigger.

Power of Sale: The Most Common Enforcement Route in Ontario

Power of sale is a process that allows the lender to sell the mortgaged property without going to court, using a contractual right that is typically built into the mortgage document and reinforced by Ontario's Mortgages Act.

The key features:

The lender sells — you do not

Unlike in a foreclosure, in a power of sale the lender sells the property on behalf of the borrower. Title does not transfer to the lender; instead, the lender arranges the sale and applies the proceeds.

The surplus (if any) goes to you

After the sale, the lender applies the proceeds in this order:

1. Sale costs and legal fees
2. Outstanding mortgage balance (principal, accrued interest, penalties)
3. Any junior charges (second mortgages, liens)
4. Any remaining amount (the surplus) — to the borrower

This is an important protection for borrowers: if the property sells for more than the total debt, you receive the difference. The lender cannot profit from the sale beyond recovering what it is owed.

You remain personally liable for any shortfall

If the sale proceeds do not cover the outstanding mortgage balance — called a deficiency — the lender can sue you personally for the difference under your personal covenant. This is one of the most significant risks of default.

The timeline for power of sale in Ontario

The exact timeline is governed by the Mortgages Act and the mortgage contract. The general sequence (as of writing — verify current requirements):

1. Default occurs (missed payment or other breach)
2. Notice of Sale is served on the borrower and other interested parties. Under the Mortgages Act, the borrower has a redemption period — typically 35 days from the date of the Notice of Sale for a residential mortgage — during which the borrower can pay all arrears and costs to stop the process (called redeeming the mortgage).
3. If the borrower does not redeem, the lender proceeds to list and sell the property.
4. The lender must sell the property at a price that reflects fair market value — they cannot sell at an artificially low price that harms the borrower.

The practical total timeline (from default to completed sale) typically ranges from several months to over a year, depending on the property, market conditions, and whether the borrower contests the process.

Foreclosure: Rarer, but Fundamentally Different

Foreclosure is a court process in which the lender asks a court to extinguish the borrower's right to redeem the mortgage and vest title in the lender outright. In other words, the lender becomes the new owner of the property.

Foreclosure is rarely used in Ontario residential real estate today, for two key reasons:

1. It requires a court application — slower, more expensive, and more complex than power of sale.
2. The lender takes the title risk — in a power of sale, the borrower bears the risk if the property sells for less than expected. In a foreclosure, once the lender owns the property, they bear the risk of market movements. If the lender later sells for more than the debt, the former borrower has no claim to the surplus (in most cases).

Because of these trade-offs, most Ontario mortgage lenders — including institutional and private lenders — use power of sale rather than foreclosure.

Your Rights as a Borrower

Right to redeem: At any point before the sale is completed, you have the right to pay all arrears, costs, and legal fees to bring the mortgage current and stop the enforcement process. Even in an advanced power of sale, paying what is owed can halt the sale.

Right to sell: Before the lender completes the sale, you can sell the property yourself at fair market value and use the proceeds to pay out the mortgage. In many cases, this produces a better outcome than allowing the lender to sell — you control the process and may net a higher price.

Right to independent legal advice: You have the right to retain a lawyer at any stage of the enforcement process. Given the stakes — your home — this is not optional in practice.

Right to accounting: The lender must account for how sale proceeds were applied and pay you any surplus.

Private Lenders: Faster and Less Forgiving

Federally regulated banks and credit unions follow guidelines (including OSFI guidance) that typically require them to work with borrowers in arrears before proceeding to enforcement. These standards do not bind private lenders. A private mortgage lender can move to power of sale as soon as the law permits — and may do so quickly.

If you have a private mortgage, missing even one payment can start the clock. Act early: contact the lender and your lawyer at the first sign of trouble.

What You Should Do If You Are in Default

1. Do not ignore it. Missing payments and hoping the situation resolves itself is the worst strategy. The enforcement process continues whether or not you open the mail.
2. Talk to your lender. Institutional lenders often have hardship accommodation options — deferral, payment restructuring. Private lenders may also prefer a negotiated solution to a costly enforcement process.
3. Get legal advice immediately. A lawyer can advise on your redemption rights, the validity of the Notice of Sale, and whether any procedural errors give you grounds to contest or delay enforcement.
4. Consider selling voluntarily. If you cannot service the mortgage, selling on your own terms (and timeline) before the lender takes over gives you more control and may result in a better net outcome.
