Key takeaways
  • If a seller fails to close, the buyer's damages are presumptively the difference between the contract price and the market value on the closing date.
  • A court order forcing the sale to close is not automatic; the buyer must show the property is unique and that damages would be inadequate.
  • Courts should be reluctant to order a sale to close where the property was bought solely as an investment.

The closing date arrives and the seller says they will not hand over the home. Perhaps they found a better offer, perhaps the market moved, or perhaps they simply changed their mind. You have an agreement of purchase and sale, a moving date and probably a mortgage commitment, and you need to know where you stand.

This article explains, in general terms, the main options a buyer has in Ontario and what the Court of Appeal for Ontario has said about them. Every situation turns on its own facts and on the exact wording of your agreement, so treat this as a map and not as advice on your file.

Start by confirming what is really happening

A seller who is late, a seller who needs a short extension and a seller who flatly refuses are three different situations. Before thinking about remedies, pin down which one you are in, and make sure you are not the one who is unready.

If time is of the essence in your agreement and neither side is ready to close on the agreed date, the agreement stays in effect. Either party can restore time of the essence by setting a new closing date and giving the other party reasonable notice. Changing a closing date is normally done by a written amendment that both sides sign, so keep any extension in writing.

Remedy one: damages

The usual starting point is money. When a seller fails to close, the buyer's damages are presumptively the difference between the contract price and the market value of the land on the closing date. If the market value equals the contract price on that date, there is no loss.

This is why a refusal in a flat market can leave a buyer with little to claim in damages, while a refusal in a rising market can be costly. A buyer who sues for damages must also take reasonable steps to limit the loss, because a plaintiff cannot recover losses that reasonable steps could have avoided. The defendant has to prove both that the plaintiff failed to mitigate and that mitigation was possible.

Remedy two: asking a court to force the sale to close

Specific performance is a court order that makes the sale go through. It is not granted as a matter of course. The buyer must show the property is unique, meaning a substitute is not readily available, and that damages would be inadequate. Courts weigh the nature of the property, the adequacy of damages and the parties' conduct.

Uniqueness does not mean the property is one of a kind. It means the property has qualities that make it especially suitable for the buyer's use and that cannot readily be duplicated, judged from the buyer's point of view when the contract was made. A rising market can support this.

There is an important exception. Courts should be reluctant to order specific performance of a purchase of property bought solely as an investment. A buyer who planned to live in the home, or to use it for a particular purpose, is generally in a different position from one who bought only to resell or rent.

Comparing the two main remedies

DamagesSpecific performance
What you getMoney, measured against market value on the closing dateAn order that the sale be completed
What you must showThe loss, and reasonable steps to limit itThe property is unique and damages would be inadequate
Weak pointNo loss if market value equals the contract priceInvestment purchases, where courts should be reluctant

The two remedies are not a menu you can freely choose from. A court looks at the facts, and the right approach depends on the property, your reasons for buying and what has happened in the market.

What to do next

Time matters. Evidence about the property's market value and about why it suited you is easier to gather early, and delay can make it harder to show you were ready to close. The deposit is usually held in trust by a brokerage, and the balance owing to the seller can be released only when the transaction is completed or with the mutual written consent of both parties. Do not sign anything that releases the deposit without understanding what you are giving up.

Frequently asked questions

Can I force the seller to close?

Possibly, but a court will not order it automatically. You would need to show the property is unique and that damages would be inadequate. Courts should be reluctant to make that order for property bought solely as an investment.

What are my damages if the seller backs out?

They are presumptively the difference between the contract price and the market value of the land on the closing date. If the two are equal on that date, there is no loss.

Does a rising market help my case?

It can. A rising market can support the argument that the property is unique for specific performance purposes. It also tends to increase the difference between contract price and market value for damages.

What if neither of us was ready to close on the date?

If time is of the essence and neither party is ready, the agreement stays in effect. Either party can restore time of the essence by setting a new closing date and giving reasonable notice.
