Key takeaways
  • Under Part III of the Mortgages Act, the lender must give a notice of sale to those entitled to it, and the lender's solicitor certifies compliance.
  • A spouse who was not served can matter to the sale, because a Family Law Act spousal status statement is needed on the transfer in that situation.
  • A power of sale transfer does not automatically wipe out construction liens, condominium liens, land tax arrears or certificates of pending litigation.
  • The exact notice and redemption periods depend on your mortgage and the Act, so confirm your own dates with a lawyer as soon as you get a notice.

Falling behind on a mortgage is frightening, and a letter from the lender's lawyer can make it feel as though the sale is already decided. Power of sale is a process in which the lender sells the property itself, and that process has rules the lender must follow.

This article explains in plain terms how power of sale generally works, who must be notified, what the sale does and does not clear away, and what you can do while there is still time. It is general information. Your mortgage terms and the dates on your notice decide your real timeline.

What power of sale means

Most mortgages contain a clause that lets the lender sell the property if you default. Default usually means missed payments, but it can also include other breaches, such as unpaid property taxes or insurance, depending on what your mortgage says. Power of sale is the lender's right to sell and use the proceeds to pay what is owed.

Under Part III of the Mortgages Act, the lender must give a notice of sale. That notice goes to those entitled to receive it, and the lender's solicitor later certifies that Part III was followed. The specific number of days that apply at each stage is something to confirm on your own notice and with a lawyer, because the dates you need are the ones in your documents.

Who must be told, and why it matters

The notice is not only for the borrower. It must go to everyone entitled to it, and the solicitor handling the transfer must confirm that notice was given to all entitled persons and that Part III was complied with. If a spouse was not served, a Family Law Act spousal status statement is needed on the power of sale transfer.

For you, this means a defect in who was told can become a real issue. If you think notice was missed for you, a spouse or another person with an interest, raise it with a lawyer promptly rather than waiting for the sale to close.

What a sale does not wipe out

Buyers and owners often assume a power of sale clears every claim against the property. That is not the case. A power of sale transfer does not automatically delete construction liens, condominium liens, land tax arrears or certificates of pending litigation.

Item on titleRemoved automatically by the transfer?
Construction lienNo
Condominium lienNo
Land tax arrearsNo
Certificate of pending litigationNo

This matters to you because unpaid amounts of this kind can reduce what is left for you after the sale, and they can affect how easily the lender finds a buyer.

How the transfer gets registered

When the property is sold, the Land Registrar accepts one of two kinds of evidence for the transfer: a set of declarations attached to the transfer, or solicitor-signed statements in the transfer. A combination of the two is not accepted. Registration of the transfer requires a lawyer, since only a lawyer can sign for completeness an electronic registration document that requires compliance-with-law statements.

You do not need to understand the registration mechanics, but it helps to know that a lawyer on the lender's side is putting their professional certification behind the notice steps. If the steps were not followed, that is where a problem would show up.

Your options while there is still time

If you sell, remember the tax side. CRA says all sales of real property, including a principal residence, must be reported, even where there is no gain or the gain is fully exempt.

What to do next

Frequently asked questions

Can I stop a power of sale in Ontario?

It depends on your mortgage, how much is owed and what the lender has done so far. Options generally include bringing the loan up to date, refinancing, selling the property yourself, or challenging a defect in the process. A lawyer can tell you which are open on your dates.

Does the lender have to tell me before selling?

Yes. The lender must give a notice of sale under Part III of the Mortgages Act, and it goes to those entitled to it. The lender's solicitor then certifies compliance with Part III on the transfer.

Will a power of sale clear liens and tax arrears?

Not automatically. Construction liens, condominium liens, land tax arrears and certificates of pending litigation are not automatically deleted by a power of sale transfer.

What if my spouse was never served?

A Family Law Act spousal status statement is needed on a power of sale transfer where a spouse was not served. Whether that affects your situation depends on the facts, so it is worth raising with a lawyer quickly.
