Key takeaways
  • A lender generally cannot give a notice of exercising a power of sale until the default has lasted 15 days, and the sale cannot happen until at least 35 days after the notice.
  • Before a sale, you can usually end the default by paying the arrears plus the lender's necessary expenses, even if the whole debt has been accelerated.
  • If the lender has already started a court action, you can pay $100 into court as security for costs and then pay what is due.

Falling behind on your mortgage is stressful, and a letter that mentions a power of sale can feel like the clock has already run out. In Ontario, the Mortgages Act sets minimum time periods and service rules that a lender must follow before it can sell your home.

This article explains those timelines, who must receive the notice, and the main ways a homeowner can try to stop a sale. It is general information, not advice on your situation. If you have a notice in hand, a lawyer can check the dates and the paperwork against your mortgage.

The basic power of sale timeline

Most mortgages contain a power of sale clause, which lets the lender sell the property if you default. The Mortgages Act limits how fast that can happen. The lender cannot give a notice of exercising a power of sale until the default has continued for at least 15 days, and the sale cannot be made until at least 35 days after the notice is given.

Default usually means not following the terms of the mortgage, such as missing a regular payment. If it continues, the lender can seek repayment, which may eventually lead to a forced sale of the home.

The longer timeline for mortgages without a power of sale clause

A different set of rules applies if the mortgage has no power of sale clause of its own. The statutory power to sell then arises only after three months of default. No sale may be made until 45 days' written notice has been given, and that notice may be given at any time after 15 days of default.

This statutory power does not apply to a mortgage that has its own power of sale, and none of that Part applies to a mortgage that declares it does not apply. Which timeline governs you depends on the wording of your mortgage, so check it carefully.

Who must get the notice and how it must be given

The lender may not exercise a power of sale unless the notice has been given to the listed persons. These include persons shown on the parcel register and index of executions, the Crown or a public authority claiming a statutory lien if the lender has written notice of it, and anyone who gave the lender written notice of an interest before the notice of sale.

The notice must be given by personal service or by registered mail, addressed to the person's usual or last known address or an address set out in the mortgage. A notice sent by registered mail must be mailed in Ontario and is deemed given on the day it is mailed.

Once the lender has given a demand or notice of sale, it generally may not start any further proceeding to enforce the mortgage during the time set in the notice without an order from a judge of the Superior Court of Justice. The judge may make that order without notice or on whatever notice the judge directs. This bar does not apply to proceedings to stop waste or other injury to the mortgaged property.

Ways to stop a power of sale

How a judge would apply that last option depends on your facts, so it is worth speaking to a lawyer quickly.

What to do next

Note that these bank relief measures are expected of federally regulated institutions such as banks. They do not apply to private lenders or Ontario credit unions, so what your lender offers may differ.

Frequently asked questions

How long does a power of sale take in Ontario?

The default must continue at least 15 days before the notice can be given, and the sale cannot happen until at least 35 days after the notice. Mortgages with no power of sale clause follow a longer timeline of three months' default and 45 days' notice.

Can I stop a power of sale by paying the arrears?

Generally, yes, if you act before a sale. You can be relieved of the default by paying the arrears plus the lender's necessary expenses, even if the whole debt has been accelerated. You can ask the lender in writing for a statement of those amounts.

Can the lender charge higher interest on my arrears?

Not above a certain limit. No fine, penalty or rate of interest may be charged on arrears that would make the charge higher than the rate payable on principal not in arrears. You can also have the lender's costs assessed.

What if the notice of sale was done wrongly?

Where a notice was given in professed compliance with Part III of the Mortgages Act, a buyer's title cannot be impeached on the ground that Part III was not complied with. You keep a remedy, such as damages, against the person who exercised the power of sale. A lawyer can review whether that applies to you.
