What Happens to a Second Mortgage in a Power of Sale?

A meaningful share of the power of sale activity we track involves properties with more than one mortgage registered against them — and understanding how priority actually works matters whether you're a buyer, a homeowner, or holding the second mortgage yourself.

What "Priority" Actually Means

When more than one mortgage is registered against a property, priority is generally determined by registration order — the first mortgage registered gets paid first from any sale proceeds, with subsequent mortgages paid only from whatever remains. This is exactly why a second mortgage typically carries a higher interest rate than a first: the lender is taking on more risk, since they're only repaid after the first mortgage is fully satisfied.

How Sale Proceeds Are Actually Distributed

Under Section 27 of Ontario's Mortgages Act, when a power of sale closes, proceeds are applied in a specific order:

1. Costs of the sale — legal fees, real estate commissions, and other expenses of conducting the sale

2. The enforcing mortgage's principal and interest owing

3. Subsequent encumbrancers — including a second mortgage, in order of their registered priority

4. Any remaining surplus — returned to the original homeowner

What This Means If the First Mortgage Is Enforcing

This is the most common scenario: if the first mortgage holder is the one exercising power of sale, the second mortgage holder is entitled to receive whatever remains after the first mortgage and sale costs are fully paid — but nothing is guaranteed if there isn't enough equity to cover both. Second mortgage lenders size their loans conservatively against remaining equity for exactly this reason.

What This Means If the Second Mortgage Holder Is Enforcing

A second mortgage holder can also exercise power of sale rights if the borrower defaults on the second mortgage specifically — but the first mortgage doesn't simply disappear. The property is generally sold subject to the first mortgage remaining in place, or the first mortgage needs to be paid off or otherwise addressed as part of the sale, since the first lender's priority claim doesn't go away just because the second lender is the one enforcing.

Notice Requirements Protect Every Registered Party

Ontario's Mortgages Act requires the Notice of Sale to be served on every person with a registered interest in the property — including any second mortgage holder or lienholder, not just the borrower. This ensures every party with a financial stake gets the opportunity to respond, redeem, or protect their position before a sale proceeds.

What This Means for Buyers

• A property with multiple registered mortgages isn't automatically riskier to buy — once the sale closes properly, all prior encumbrances are typically discharged from title as part of the transaction, provided the process was followed correctly.

• Confirm with your lawyer that all registered interests have been properly addressed as part of your purchase, so you're taking clear title, not one still burdened by an unresolved second mortgage.

What This Means If You Hold a Second Mortgage as a Private Lender

If you're a private lender holding a second position on a property heading toward power of sale by the first mortgage holder, understand that you're entitled to notice and to whatever proceeds remain after the first lender and sale costs are covered — but recovery isn't guaranteed if the property's equity doesn't stretch that far. This is exactly the kind of exposure we've discussed in the context of private lending's growing role in the current GTA market.

What This Means for Homeowners With a Second Mortgage in Default

If you're behind on a second mortgage specifically, understand that your first mortgage lender's rights aren't affected by what's happening with your second — but a default on either can ultimately put the property at risk. Addressing financial stress on any registered mortgage early gives you more options than waiting.

The Bottom Line

Mortgage priority is a genuinely important factor in how power of sale proceeds get distributed — first-registered mortgages get paid first, with subsequent mortgages entitled only to what remains. Understanding this helps buyers, homeowners, and lenders alike make sense of exactly where they stand in a specific situation.
