- An offer starts as conditional when it includes conditions such as financing, home inspection, or lawyer review.
- If a buyer refuses to close a firm deal without a valid legal basis, that's a breach of contract.
- None of these outcomes is automatic, and which path a seller takes — and how a court might respond — depends entirely on the specific agreement and circumstances.
By the time an offer on an Ontario home becomes "firm" — meaning every condition has been satisfied or waived — most buyers assume the deal is essentially done. It is, legally. So can you back out of a firm offer in Ontario if you change your mind, get cold feet, or find a better property? Not without real legal and financial exposure.
A firm Agreement of Purchase and Sale is a binding contract like any other. Understanding what that actually means, and what a seller can do in response, matters whether you're the one having second thoughts or the one trying to hold a buyer to the deal.
What "Firm" Actually Means
An offer starts as conditional when it includes conditions such as financing, home inspection, or lawyer review. While those conditions remain outstanding, either party generally has a defined path to end the deal if a condition isn't satisfied. Once every condition has been satisfied or properly waived, the agreement becomes firm — a completed, binding contract with no more built-in exits.
From that point, both sides are legally expected to complete the transaction on the agreed closing date.
What Happens Legally If You Try to Walk Away
If a buyer refuses to close a firm deal without a valid legal basis, that's a breach of contract. It doesn't matter whether the reason is a change of heart, a better property elsewhere, or a financing problem that wasn't protected by a condition — none of those excuse performance once the deal is firm.
A seller facing a buyer who won't close isn't left without options, though what actually happens depends heavily on the specific facts, the wording of the agreement, and what the seller chooses to pursue.
The Seller's Possible Responses
| Response | What it generally involves |
|---|---|
| Retaining the deposit | The seller may claim the deposit already paid, though this isn't automatic — brokerages generally need a mutual release or a court order before releasing trust funds |
| Suing for damages | The seller may pursue the buyer for financial losses caused by the failed deal, such as costs from having to relist and sell to someone else at a lower price |
| Seeking specific performance | In some circumstances, courts have recognized real estate as unique enough that a seller could ask a court to order the sale to complete, rather than only awarding damages, though this isn't guaranteed in every case |
None of these outcomes is automatic, and which path a seller takes — and how a court might respond — depends entirely on the specific agreement and circumstances. This is exactly the kind of situation where general information stops being useful and legal advice starts.
Are There Any Legitimate Ways Out of a Firm Deal?
A firm deal isn't necessarily unbreakable in every conceivable circumstance, but the legitimate paths out are narrow and fact-specific rather than a matter of buyer preference:
- A mutual agreement to terminate, signed by both buyer and seller
- A properly documented failure of a condition, before it was waived, which is why the mechanics of waiving matter so much
- Limited legal doctrines that can, in rare and specific circumstances, affect the enforceability of a contract
None of these are things to rely on casually or self-assess. They require a lawyer's review of your specific agreement and facts.
What to Do If You're Reconsidering Before Closing
If you're having doubts about a firm deal, the worst move is to simply stop responding or fail to show up on closing day. Contact a real estate lawyer immediately. Depending on your situation, your lawyer may be able to open a conversation with the seller's lawyer about options, but there's no guarantee a firm deal can be unwound without cost.
Frequently asked questions
What's the difference between a conditional offer and a firm offer?
A conditional offer still has one or more outstanding conditions, like financing or inspection, that give a party a defined way to exit if the condition isn't met. A firm offer has no outstanding conditions and is a fully binding contract.
Will I definitely lose my deposit if I don't close?
Not automatically. Deposit funds held in trust generally require a mutual release or a court order before they're released to either side. But a buyer in breach of a firm deal is exposed to losing the deposit, and potentially more, depending on the seller's losses and choices.
Can a seller force me to complete the purchase?
In some circumstances, yes — courts have, in certain cases, ordered a buyer to complete a real estate purchase rather than simply awarding the seller damages. Whether that's realistic in your situation depends entirely on the facts.
I'm getting cold feet before my deal goes firm — what should I do?
If any conditions are still outstanding, this is the time to talk to your lawyer about whether a condition genuinely isn't being satisfied, and how to document that properly, rather than staying silent and letting a deadline pass.
