You've sold your house, accepted an offer, and started preparing for moving day.
Then, just days before closing, your REALTOR® receives unexpected news:
The buyer cannot complete the purchase.
Maybe their mortgage financing fell through. Perhaps their lender changed its approval, or the buyer simply wants to walk away.
For Ontario homeowners, a failed closing can create significant financial and legal problems.
But what happens next? Can you keep the buyer's deposit? Can you sue for damages? And how do you sell your home again?
Here's what Ontario sellers should understand in 2026.
1. Can a Buyer Back Out of a House Purchase in Ontario?
Once an Agreement of Purchase and Sale becomes firm, both the buyer and seller are generally legally obligated to complete the transaction.
A firm agreement typically means all applicable conditions have been fulfilled or waived, or the offer was unconditional from the beginning.
A buyer generally cannot cancel simply because:
- They changed their mind.
- Property prices have declined.
- They found another house they prefer.
- Their mortgage lender refused financing.
- They believe they offered too much money.
However, whether a buyer is legally in breach depends on the agreement and circumstances.
Important: A buyer's inability to obtain financing does not automatically release them from a firm purchase agreement.
2. What Happens If the Buyer Doesn't Close on Closing Day?
If the buyer fails to complete the transaction, the seller should immediately contact their real estate lawyer.
The lawyer may need to establish that the seller was ready, willing, and able to complete the sale.
Depending on the circumstances, the seller may have several options:
- Negotiate a closing extension.
- Require the buyer to complete the agreement.
- Accept the buyer's breach and terminate the agreement.
- Seek forfeiture of the buyer's deposit.
- Pursue compensation for financial losses.
- Arrange to resell the property.
These options are not automatic, and the legal steps must be handled carefully.
Seller tip: Do not sign a mutual release or agree to cancel the transaction without first obtaining legal advice.
3. Can the Seller Keep the Buyer's Deposit?
This is one of the most common questions Ontario sellers ask.
In many cases, a seller may be entitled to retain the buyer's deposit when the buyer breaches a firm purchase agreement.
For example:
A buyer agrees to purchase a home for $950,000 and provides a $50,000 deposit.
The buyer later fails to close without a valid legal excuse.
The seller may have a claim to the $50,000 deposit.
However, there is an important distinction between being legally entitled to a deposit and actually receiving the money.
If the deposit is held in a real estate brokerage's trust account, it generally cannot simply be released to the seller because the buyer failed to close.
The parties may need to sign appropriate written directions, or a court order may be required.
Courts can also grant relief from forfeiture in exceptional circumstances.
4. Can the Seller Sue the Buyer for More Than the Deposit?
Potentially, yes.
If a buyer breaches a firm agreement and the seller suffers financial losses, the seller may be entitled to claim damages.
Possible losses include:
- A reduction in the property's value
- Additional mortgage carrying costs
- Property taxes during the delay
- Additional insurance and utility expenses
- Reasonable costs associated with reselling
- Certain additional legal and transaction expenses
Not every expense is automatically recoverable. The seller must establish the legal basis for the claim and provide supporting evidence.
Example: Buyer Fails to Close on a $1 Million Home
Imagine the following situation:
ItemAmountOriginal agreed selling price$1,000,000Subsequent resale price$920,000Difference in selling prices$80,000Additional eligible expenses (illustrative)$10,000Potential gross loss$90,000Buyer deposit credited against loss−$40,000Illustrative remaining claim$50,000
This simplified example is not a prediction of what a court would award.
The legal calculation can depend on the property's market value at the relevant date, the reasonableness of the resale process, the agreement, and the evidence.
The deposit is generally credited against compensatory damages rather than allowing the seller to recover the same loss twice.
5. What If the Buyer's Mortgage Financing Falls Through?
Financing problems are a common reason real estate transactions fail.
For example, a buyer may receive mortgage pre-approval but encounter problems before closing.
Possible causes include:
- Changes in employment or income
- Increased debt
- Property appraisal concerns
- Changes in the lender's underwriting decision
- Incomplete financing documentation
If the purchase agreement is firm, financing difficulties generally do not automatically excuse the buyer from completing the transaction.
If a valid financing condition remains in effect, however, the buyer's rights may be different.
That is why the exact wording and status of the conditions matter.
6. Should the Seller Agree to Extend the Closing Date?
Sometimes an extension is the most practical solution.
Suppose a buyer needs five additional business days to finalize mortgage financing.
Rather than immediately pursuing litigation, the seller might consider a negotiated extension.
Possible extension terms could address:
- A new firm closing date
- Additional deposit money
- Compensation for extra carrying costs
- Confirmation of the buyer's financing progress
- Protection of the seller's legal rights if the buyer defaults again
All extension terms should be reviewed and documented by the parties' lawyers.
Seller tip: An extension may help save the transaction, but it should not be granted casually.
7. Can the Seller Put the House Back on the Market?
Generally, a seller may be able to relist after the original agreement has been properly terminated.
However, sellers should not assume that a missed closing automatically means they are free to sell to someone else.
The lawyer should first advise on the status of the original contract and the steps required to terminate it.
Once the property can legally be resold, the seller should consider:
- Reviewing current comparable sales
- Setting a competitive asking price
- Refreshing listing photos and marketing
- Contacting previously interested buyers
- Making the home accessible for showings
- Documenting all offers and marketing efforts
A seller who suffers losses from a buyer's breach generally has a duty to take reasonable steps to minimize those losses.
This is known as mitigation of damages.
8. What If the House Sells for Less the Second Time?
A lower resale price can be relevant to a damages claim.
For example, a property originally sold for $1.2 million might later sell for $1.1 million.
That $100,000 difference may be evidence of a financial loss, but it does not automatically establish a $100,000 legal entitlement.
Ontario courts may consider market value at the relevant date, the seller's resale efforts, and other circumstances.
In a June 2026 Ontario Court of Appeal decision, Eyelet Investment Corp. v. Zhou, the court considered the importance of market-value evidence when determining damages after a buyer's breach.
The practical lesson for sellers is straightforward:
Keep detailed records and consider obtaining professional valuation evidence when appropriate.
9. What Should Sellers Do Immediately After a Failed Closing?
If your buyer fails to close, the first few days are important.
Contact your lawyer immediately
Confirm the legal status of the agreement and available remedies.
Preserve all documents
Keep copies of the Agreement of Purchase and Sale, amendments, deposit records, emails, and closing correspondence.
Track your expenses
Document mortgage interest, property taxes, utilities, insurance, and other expenses associated with the delay.
Discuss your resale strategy
Once your lawyer confirms that the property can be marketed again, work with your REALTOR® on a practical plan.
Avoid emotional decisions
A failed closing is stressful, but pricing the property unrealistically or refusing reasonable opportunities to resell could complicate your situation.
10. Frequently Asked Questions
Can a buyer lose their entire deposit if they don't close in Ontario?
Yes. A buyer who defaults on a firm purchase agreement may forfeit the deposit, subject to the contract and applicable legal principles.
Does the seller automatically receive the deposit?
No. If the deposit is held in a brokerage trust account, its release generally requires proper written authorization or a court order.
Can a buyer cancel because the bank refused the mortgage?
If the agreement is firm, financing problems generally do not automatically excuse the buyer from closing.
Can the seller sue the buyer for the difference in price?
Potentially. A seller may pursue damages, but the amount depends on the evidence, market value, mitigation, and other legal considerations.
Can a seller refuse a closing extension?
Depending on the agreement and circumstances, a seller may be entitled to refuse a requested extension. Legal advice is important before responding.
How long does a seller have to sue a buyer?
Ontario generally has a basic two-year limitation period for many civil claims, but the start date and possible exceptions depend on the facts. Speak with a litigation lawyer promptly rather than assuming you have two full years from the failed closing.
Can the seller accept another offer immediately?
Not necessarily. The original agreement must be properly dealt with first. Your lawyer should confirm when you are legally free to enter another sale agreement.
Final Thoughts: A Failed Closing Doesn't Mean You Have No Options
When a buyer fails to close on an Ontario home purchase, the consequences can be serious.
The seller may have legal remedies, including a claim to the deposit and compensation for certain financial losses.
But protecting those rights requires careful legal advice, proper documentation, and reasonable decisions about reselling the property.
