What Happens If Your Markham
Buyer Backs Out After
Conditions Are Waived?

A firm deal in Markham real estate — one where all conditions have been waived and the Agreement of Purchase and Sale is unconditional — is supposed to be binding. But buyers occasionally back out even after going firm, leaving sellers in a situation that is legally complex, financially damaging, and emotionally distressing. Understanding exactly what your rights are as a Markham seller, what remedies are available, and what steps to take immediately when a buyer backs out of a firm deal is essential knowledge — and Michael John Lau and Neeraj Moolchandani at Kaizen Real Estate Team guide sellers through this situation with urgency and expertise.

What "Firm Deal" Means in Ontario Law

In Ontario, a real estate transaction becomes "firm" when the Agreement of Purchase and Sale (APS) has been executed by both parties and all conditions — financing, home inspection, status certificate review — have been waived or satisfied in writing. Once an agreement is firm, both parties have legally binding obligations: the seller to deliver the property and the buyer to close the transaction on the agreed closing date.

A firm APS is a contract. When a buyer backs out of a firm deal in Ontario without legal justification, they are in breach of contract. The seller has the right to pursue remedies — beginning with the deposit and potentially extending to legal action for additional damages.

Important: Get Legal Advice Immediately

If your Markham buyer has backed out of a firm deal, contact a real estate lawyer immediately — before taking any action, signing any documents, or communicating with the buyer or their agent about next steps. The decisions made in the first 24–48 hours significantly affect your legal position and the remedies available to you.

Why Buyers Back Out of Firm Markham Deals — And Whether It Changes Your Options

The reason a buyer backs out of a firm Markham deal affects the emotional context but rarely changes the seller's legal remedies. Common reasons include: financing that falls through after conditions are waived, cold feet, a change in personal circumstances, discovering another property they prefer, or a material change in the buyer's financial situation. In most of these cases, the legal outcome is the same: the buyer is in breach, and the seller is entitled to remedies.

The exception: if the seller has materially breached the APS first — for example, by failing to disclose a known defect that constitutes a fraudulent misrepresentation — the buyer may have legal grounds to void the agreement. This is a narrower exception than many sellers fear, and requires legal assessment on the specific facts.

Your Four Options as a Markham Seller

01
Keep the Deposit — Mutual Release

The fastest resolution. Both parties sign a Mutual Release terminating the APS, and the deposit is released to the seller as full and final settlement of the breach. This requires the buyer's agreement — and the buyer must consent to releasing the deposit to the seller rather than having it returned to them. In most cases where a buyer has simply changed their mind, a negotiated mutual release is the most practical outcome.

02
Pursue Additional Damages — Civil Action

If the deposit does not cover the seller's actual losses, the seller can pursue the buyer for additional damages through Ontario's Small Claims Court (up to $35,000) or the Superior Court of Justice for larger amounts. Recoverable damages include: the difference between the original sale price and the eventual resale price, additional carrying costs during the delay, and legal fees in some circumstances. This path is slower and more costly — but sometimes necessary.

03
Seek Specific Performance

In rare circumstances, a seller may apply to the Ontario court for an order of "specific performance" — compelling the buyer to complete the purchase. Courts are reluctant to grant this remedy in residential real estate transactions and typically prefer damages as the remedy for breach. This option is rarely practical in a Markham residential context.

04
Relist and Sell to a New Buyer

The seller terminates the failed APS (either through mutual release or legal process), relists the property, and sells to a new buyer. Any losses incurred in the relisting process — price reduction, carrying costs, additional agent fees — can be claimed against the original buyer as damages. Kaizen Real Estate Team prepares a relisting strategy immediately to minimize the seller's market exposure time.

The Deposit — What You're Entitled To and How to Access It

In Ontario, the deposit paid by a buyer in a real estate transaction is held in trust by the listing brokerage — not by the seller. When a buyer backs out of a firm deal, the deposit does not automatically flow to the seller. It requires either a mutual release signed by both parties directing the deposit to the seller, or a court order directing its release.

This creates a common and frustrating situation: the buyer backs out, but then refuses to sign a mutual release because they want their deposit back. In this scenario, the deposit sits in trust until the dispute is resolved — either through negotiation, Small Claims Court, or the Superior Court.

01
Immediate Action
Contact Your Real Estate Lawyer — Within 24 Hours

Your first call should be to a real estate lawyer, not to the buyer or their agent. Your lawyer will assess your position, advise on whether to pursue a mutual release or prepare for litigation, and communicate with the buyer's lawyer on your behalf to begin the resolution process.

02
Documentation
Document All Losses From the Moment of Breach

Begin documenting every cost and loss from the moment the buyer backs out — additional mortgage payments, property taxes, utilities, insurance, maintenance costs, and any costs incurred in relisting. These are the damages you are entitled to recover beyond the deposit. Keep all receipts and records in a dedicated file from day one.

03
Relisting
Relist Strategically — Not Reactively

Before relisting, discuss with your REALTOR® whether the original listing price is still supported by current market data. If market conditions have changed since the original listing date, repricing may be necessary. Kaizen Real Estate Team prepares a fresh CMA and market assessment before any relisting to ensure the property is positioned to sell quickly and at the best available price.

04
Resolution
Pursue Damages — Negotiation First, Litigation If Necessary

In most cases, the buyer who backs out of a firm Markham deal will ultimately agree to release the deposit to the seller rather than face the cost and uncertainty of litigation. Your lawyer's communications with the buyer's lawyer typically resolve the deposit dispute within weeks. If the buyer refuses to release the deposit and your damages exceed the deposit amount, your lawyer will advise on whether Small Claims or Superior Court action is appropriate.

How to Reduce the Risk of a Buyer Backing Out in Markham

While no strategy eliminates the risk entirely, Markham sellers can take steps to reduce the likelihood of a buyer backing out of a firm deal:

  • Require a pre-approval letter — ask for evidence of mortgage pre-approval before accepting any offer, particularly in firm or limited-condition offer situations
  • Larger deposit — a larger deposit signals buyer commitment and increases the financial consequence of backing out
  • Shorter closing date — a compressed timeline between firm date and closing reduces the window during which buyer circumstances can change
  • Qualified buyer screening — your REALTOR® can assess the credibility of buyers and their agents before accepting an offer

Frequently Asked Questions

Can a buyer back out of a firm real estate deal in Ontario?
Once all conditions have been waived and the Agreement of Purchase and Sale is firm in Ontario, a buyer cannot legally withdraw without consequences. The seller is entitled to keep the deposit and may pursue additional legal remedies if the deposit does not cover their full losses.
What happens to the deposit if a buyer backs out in Ontario?
The deposit is held in trust by the listing brokerage. If a buyer backs out of a firm deal, the seller is generally entitled to the deposit — but it requires either a signed mutual release or a court order to release it. The deposit does not automatically flow to the seller without the buyer's agreement or a court direction.
Can a Markham seller sue a buyer who backs out?
Yes. If a buyer breaches a firm Agreement of Purchase and Sale in Ontario, the seller can pursue legal action for damages beyond the deposit — including additional carrying costs and the difference between the original sale price and the eventual resale price. Consult a real estate lawyer immediately.
What is a mutual release in Ontario real estate?
A mutual release is a written agreement signed by both buyer and seller that terminates an Agreement of Purchase and Sale and specifies how the deposit will be distributed. It is the fastest resolution when a buyer backs out — but requires both parties to agree on deposit disposition.
