  • Ontario law sets out a priority waterfall — a ranked order in which the sale proceeds are paid out.
  • A surplus arises when the sale price — after subtracting the items in steps 1 through 3 above — leaves money on the table.
  • A deficiency occurs when the sale price is less than the total amount owed — the mortgage balance, accrued interest, and costs.

When an Ontario lender exercises a power of sale — the contractual right to sell a mortgaged property after a borrower defaults — the sale almost never ends the story cleanly. Once the property sells, someone has to figure out where the money goes. If the sale price is high enough to pay off everything owed, the borrower walks away with the leftover funds (the surplus). If it falls short, the borrower may still owe the difference (the deficiency). Understanding the power of sale surplus deficiency Ontario framework is essential whether you are a homeowner in default, a junior lender, or simply trying to figure out your legal exposure before the sale closes.

This article explains how Ontario law distributes sale proceeds, what your rights are on either side of the ledger, and what practical steps you should take right now.

How Sale Proceeds Are Distributed

Ontario law sets out a priority waterfall — a ranked order in which the sale proceeds are paid out. Think of it as a queue: each claimant is paid in full before the next claimant receives a dollar.

  1. Selling costs and enforcement expenses. The lender's legal fees, real estate commissions, property taxes in arrears, insurance, and any other reasonable costs of carrying out the power of sale come off the top.
  2. Principal and accrued interest owed to the selling mortgagee. The first-priority lender (the one exercising the power of sale) is then repaid the outstanding mortgage balance plus all interest that has accrued to the date of closing.
  3. Junior encumbrancers in priority order. If there are second mortgages, home equity lines of credit, or other registered charges behind the selling mortgagee, they are paid out in the order they were registered on title — each in full, if funds permit.
  4. Surplus to the borrower. Only after every charge on title has been satisfied does any remaining balance flow back to the registered owner (the borrower).

This order is not negotiable between private parties — it follows the statutory scheme and registered priority on title.

What Is a Surplus?

A surplus arises when the sale price — after subtracting the items in steps 1 through 3 above — leaves money on the table. The borrower is legally entitled to that money. It does not belong to the lender as a windfall.

How to Claim Your Surplus

The lender is obligated to account to you for the proceeds. In practice, you should:

If the lender refuses to account or delays unreasonably, you have legal remedies, including seeking a court order for the funds.

What Is a Deficiency?

A deficiency occurs when the sale price is less than the total amount owed — the mortgage balance, accrued interest, and costs. The gap between what the property sold for and what you owed is called the shortfall or deficiency.

Can the Lender Sue for a Deficiency in Ontario?

Yes. This is one of the most important distinctions between Ontario's power of sale process and the foreclosure process used in other provinces. In Ontario, a power of sale does not extinguish the borrower's personal liability on the mortgage covenant. The lender retains the right to commence a separate legal action against the borrower personally to recover the deficiency — sometimes called a deficiency judgment.

This differs from provinces where foreclosure (a court process that transfers title to the lender) eliminates the borrower's personal debt. Under Ontario's power of sale regime, you can lose the property and still owe the bank money.

The limitation period for a deficiency claim is governed by the general two-year limitation period under Ontario's Limitations Act (as of writing — verify), running from the date the lender's loss is ascertainable (typically the closing date of the power of sale). Borrowers should not assume the risk disappears once the property sells.

The Lender's Duty to Obtain a Fair Price

The lender's right to pursue a deficiency is not unlimited. Ontario law — both the Mortgages Act and the common law duty of care — imposes an obligation on the selling mortgagee to take reasonable care to obtain a fair market value (sometimes called a "reasonable price") for the property. The lender cannot rush the sale, accept an artificially low offer from a connected party, or skip proper marketing in order to close quickly — and then turn around and sue for a large deficiency.

What "Fair Price" Means in Practice

If a court finds the lender sold at an undervalue, the deficiency claim may be reduced or eliminated — the court will credit the borrower with what the property should have sold for, not what it actually sold for.

Challenging an Undervalue Sale

If you believe the lender undersold the property, you will need evidence:

Time matters here. Retain a lawyer and an appraiser as quickly as possible after you learn the sale has closed. Evidence becomes harder to assemble as time passes and the market moves.

Junior Mortgagees and Their Claims

A junior lender — a second mortgagee or line of credit holder registered behind the first mortgage — stands in line after the selling mortgagee in the waterfall. If there is no surplus after the first mortgage is paid, junior lenders receive nothing from the sale proceeds.

Critically, however, a junior lender also retains its personal covenant against the borrower. A second mortgage that is wiped out by the first lender's power of sale does not vanish: the second lender can still sue the borrower for the outstanding balance. Borrowers facing a first mortgage power of sale should immediately assess their exposure to junior lenders as well.

Practical Steps for Borrowers

Frequently asked questions

What happens to surplus funds if there is no mortgage behind the selling lender?

If there are no junior encumbrancers, the surplus flows directly to the borrower (the registered owner) after the selling mortgagee is paid out in full. The lender must account to you for the proceeds. If you do not act to claim the funds, the lender may pay the surplus into court, requiring you to bring a motion to retrieve it.

Can a lender pursue a deficiency judgment years after the power of sale?

Generally no. Ontario's Limitations Act sets a two-year limitation period for most claims (as of writing — verify). That clock typically starts on the closing date of the power of sale, when the lender's loss becomes clear. A lender that waits more than two years to sue risks having the deficiency claim dismissed, though the precise start date can be fact-specific. Get legal advice if you are uncertain when your limitation period began.

Can I negotiate a deficiency with my lender without going to court?

Yes, and many lenders prefer to negotiate rather than litigate. A borrower who is judgment-proof (no assets, no income to garnishee) gives the lender little practical incentive to sue. That said, do not negotiate a deficiency settlement without independent legal advice — you may be releasing claims (such as a duty-of-fair-price argument) that are worth money to you.

Does a power of sale affect my credit differently than a foreclosure?

Both a power of sale and a foreclosure appear on your credit file as a serious derogatory event. The key difference is legal, not credit-reporting: under a power of sale you retain personal liability for any shortfall, whereas in some other provinces a completed foreclosure extinguishes that personal debt. Ontario uses power of sale as the primary enforcement mechanism, so assume you remain personally liable until you confirm otherwise with a lawyer.
