Can you back out of buying a house in Ontario — and what happens if you do? It is one of the most Googled real estate questions at 2:00 AM when anxiety is peaking. Whether you are a buyer having second thoughts after signing, or a seller who wants out of an accepted deal, the consequences in Ontario are serious and the rules are clear. This guide explains exactly what happens when someone tries to back out of buying a house in Ontario, and what both buyers and sellers can do to protect themselves.

Please note: this post provides general information only and does not constitute legal advice. If you are trying to back out of buying a house in Ontario or are facing a closing dispute, always consult a licensed Ontario real estate lawyer. For your specific situation, legal advice is essential.

Can You Back Out of Buying a House in Ontario? The Agreement of Purchase and Sale

In Ontario, when a buyer’s offer is accepted by the seller, both parties sign an Agreement of Purchase and Sale (APS). This is a legally binding contract. The moment all parties sign and the deal becomes firm — meaning all conditions have been waived or fulfilled — walking away from the transaction can have serious legal and financial consequences.

There is an important distinction between backing out of a conditional deal versus a firm deal. A conditional deal has protections built in. A firm deal has very few. Understanding which situation you are in is the first critical step.

What Happens When You Back Out of Buying a House in Ontario as a Buyer

Backing Out During the Conditional Period

Most offers in Ontario include conditions — most commonly a financing condition and a home inspection condition. These conditions give the buyer a specified window of time (typically 5 to 10 business days) to investigate the purchase and either confirm they want to proceed or exercise their right to walk away.

If you are a buyer and you back out during the conditional period by properly exercising one of your conditions — for example, you cannot secure financing, or the home inspection reveals major issues — you are generally entitled to a full refund of your deposit and you walk away with no further obligations. This is why conditions exist: they are buyer protections built into the offer.

However, conditions must be used in good faith. You cannot simply invent a reason that a condition was not satisfied. A financing condition, for example, is meant to protect you if you genuinely cannot obtain financing — not to serve as a blanket escape hatch. Using conditions improperly or in bad faith can expose you to legal action.

Backing Out After the Deal Is Firm: The Consequences for Buyers

This is where things become very serious. If a buyer backs out of a firm deal — meaning all conditions have been waived and the Agreement of Purchase and Sale is fully executed — the legal and financial consequences can be severe. In Ontario, the consequences of non-closure for a buyer typically include the following.

First, the buyer forfeits their deposit. In a typical Ontario real estate transaction, the deposit ranges from $10,000 to $50,000 or more on higher-priced properties. When a buyer fails to close, they lose this deposit entirely. The seller is entitled to keep the deposit as compensation for the buyer’s breach of contract.

Second, the buyer can be sued for damages beyond the deposit. If the seller re-lists the property and sells it for less than the original deal price, the seller can pursue the original buyer for the difference. If the original deal was for $950,000 and the seller ultimately has to accept $880,000 from a new buyer, the original buyer could be sued for the $70,000 difference — plus carrying costs the seller incurred during the extended period (mortgage payments, property taxes, utilities, and marketing costs). These claims are taken seriously by Ontario courts.

Third, the legal costs involved in pursuing or defending such claims add up quickly. Even if the seller does not ultimately sue, the buyer’s legal fees for navigating the fallout of a failed closing can be substantial.

What Buyers Can Do If They Are Having Second Thoughts

If you are a buyer having serious doubts after a deal becomes firm, the most important step is to contact a real estate lawyer immediately. Do not simply stop communicating with your agent or the seller. There may be options — mutual agreement to rescind the contract, renegotiating terms, or finding a creative solution — but these require proactive communication and legal guidance.

In some cases, life circumstances genuinely change in ways that make a purchase impossible — sudden job loss, a medical emergency, a family crisis. While Ontario real estate law does not have a general “cooling off period” for resale homes the way some jurisdictions do, courts do consider extreme circumstances. But do not count on sympathy — the law is generally clear on the obligations of parties to an Agreement of Purchase and Sale.

What Happens If a Seller Backs Out of a Real Estate Deal in Ontario

It is less common, but sellers do sometimes attempt to back out of accepted deals — often because they received a better offer or their circumstances changed. In Ontario, a seller who backs out of a firm deal faces equally serious consequences.

The Buyer’s Rights When a Seller Backs Out

When a seller refuses to close on a firm deal in Ontario, the buyer has several legal remedies. The most powerful is specific performance — a court order requiring the seller to complete the transaction as agreed. Courts in Ontario have granted specific performance in real estate transactions, particularly for unique properties where monetary damages alone are considered insufficient to make the buyer whole.

Buyers can also sue for damages if the property is ultimately sold to someone else for a higher price — or if the buyer incurs costs as a result of the seller’s refusal to close, including the cost of alternate accommodations, legal fees, and moving expenses that were arranged in anticipation of the closing.

The deposit is returned to the buyer in full if the seller is the party that fails to close, but the legal action does not stop there. Ontario courts take a dim view of sellers who accept an offer and then attempt to back out for financial gain.

Can a Seller Accept a Better Offer After Signing?

No — not legally. Once a seller has signed an accepted Agreement of Purchase and Sale, they are bound by that contract. A seller cannot unilaterally cancel the deal because a higher offer came in. Attempting to do so is a breach of contract with the same serious consequences described above. This is a common misunderstanding among sellers, and it is one reason why it is critical to be certain before accepting any offer.

The Ontario Cooling Off Period: Does It Apply to Resale Homes?

Ontario does have a 10-day cooling off period — but it applies only to new condominium purchases under the Condominium Act, not to resale residential properties. If you purchase a pre-construction condo from a builder in Ontario, you have 10 days to rescind the agreement with no penalty. This protection does not exist for purchases of existing resale homes, resale condos, or new freehold homes. Many buyers are surprised to learn this, particularly those coming from jurisdictions with broader consumer cooling-off protections.

How to Protect Yourself Before You Sign

The best protection against the painful consequences of backing out of a real estate deal in Ontario is being absolutely certain before you make your deal firm. That means completing a thorough home inspection before waiving your inspection condition. It means having a fully approved mortgage commitment — not just a pre-approval — before waiving your financing condition. It means consulting a real estate lawyer before closing, not just after a problem arises. And it means working with an experienced real estate agent who helps you understand exactly what you are committing to at every stage of the transaction.

Conditions are your safety valves. Use them properly and thoroughly, and firm them up only when you are genuinely ready to proceed.

Frequently Asked Questions: Backing Out of a Real Estate Deal in Ontario

Can I back out of buying a house after the home inspection in Ontario?

Yes — if your offer includes a home inspection condition and the inspection reveals issues that give you legitimate grounds to exercise the condition, you can withdraw from the deal and receive your deposit back. The condition must be used in good faith, meaning genuine concerns about the property’s condition, not simply a change of heart.

How long do I have to back out of a house purchase in Ontario?

For resale homes, there is no statutory cooling off period. Your window to exit is during the conditional period only. Once all conditions are waived and the deal is firm, you are contractually bound to close.

What happens to the deposit if a real estate deal falls through in Ontario?

If a deal falls through during the conditional period due to a properly exercised condition, the deposit is returned to the buyer. If a firm deal collapses because the buyer refuses to close, the seller is typically entitled to keep the deposit. If the seller refuses to close, the deposit is returned to the buyer and additional damages may be pursued through the courts.

Can a real estate deal be cancelled by mutual agreement in Ontario?

Yes — if both the buyer and seller agree to mutually rescind the Agreement of Purchase and Sale, they can legally dissolve the contract. This mutual release must be documented in writing and signed by both parties. The treatment of the deposit is negotiated as part of the mutual release. This is the cleanest resolution when both sides want out, but it requires agreement from both parties — one side cannot force a mutual release.
