How long after signing a contract can you cancel?
Can you cancel a home sale after signing? Here’s exactly how long you have — and how it works in Milton, ON.
Quick, direct answer
There is no automatic “cooling-off” period for resale home purchase agreements in Ontario. Once you sign a legally binding purchase agreement in Milton, you cannot unilaterally cancel without consequences unless the contract contains specific conditions (“subjects”) that are not cleared by their deadlines. If you try to back out without a valid contractual or legal reason, you risk losing your deposit and facing legal claims.
Why this matters right now in Milton
Milton‘s market moves fast. Offers are competitive. Buyers and sellers sign binding agreements within days. That speed makes it critical to know the rules up front: missing a conditional deadline or assuming a right to cancel can cost tens of thousands of dollars and wreck your closing schedule.

The legal reality in Ontario (simple, no legalese)
- Resale homes: No statutory cooling-off period. Once the buyer and seller sign a complete agreement, it’s binding. The only ways out are the contract’s own conditions, mutual agreement, or court intervention for fraud, misrepresentation, or duress.
- Conditional (subject to) offers: These are your lifeline. Common conditions include financing, home inspection, and sale of the buyer’s current home. If a condition is not satisfied or waived by its deadline, the party protected by the condition can cancel without penalty.
- New-build homes or purchase from a builder: Different rules and consumer protections may apply (Tarion warranty, specific disclosure rules). Always check the contract and get legal advice.
How long after signing can you cancel? The practical timeline
- If the agreement is unconditional: effectively zero. You can’t cancel without possible breach of contract and financial consequences immediately after signing.
- If the agreement is conditional: you can cancel up until the condition’s expiry time. Typical timelines in Milton:
- Financing: 3–7 business days (or whatever the offer specifies)
- Home inspection: 3–10 business days
- Sale of buyer’s property: 5–10 business days
Read the offer carefully — the exact number of days is set by the parties in the contract.
- If you miss the conditional deadline and the condition is deemed satisfied or is waived (expressly or by conduct), the agreement becomes binding.
What happens if you try to cancel after an unconditional signing?
- You likely forfeit the deposit (or a portion of it) as liquidated damages or the seller may sue for specific performance (forcing you to complete the purchase) or additional damages.
- Legal battles are expensive. Even if you believe you have a reason, you will need a lawyer to challenge the contract. That takes time, money, and stress.
How to cancel the right way (step-by-step)
- Read the contract immediately: Know every condition and its deadline.
- Notify your realtor and your lawyer right away if you think you need to cancel.
- If you have a valid condition that isn’t met, use the correct form or written notice to remove the condition or terminate by the deadline.
- If you don’t have a valid condition, ask for a mutual release. The seller may accept a negotiated deal to avoid delay.
- If the seller refuses and you believe you have legal grounds (fraud, misrepresentation, undue influence), get a lawyer. Don’t make unilateral moves.

What about the deposit?
- Deposit is security for the seller. If you back out without a valid contractual reason, the seller can keep the deposit and pursue further damages.
- If cancellation follows a condition that was not satisfied, deposit is typically returned to the buyer.
- Keep deposit receipts and ensure your offer states the deposit handling clearly (trust account, timing, and amount).
Common scenarios in Milton and the practical outcomes
- Buyer can’t get financing by the deadline: If the financing condition is not satisfied and you provide proof, you cancel cleanly and get the deposit back.
- Buyer discovers major defects in inspection: If the inspection condition isn’t waived and parties can’t agree on repairs or price adjustments, buyer can cancel and get deposit back.
- Buyer has buyer’s remorse with no conditions: Seller can keep deposit and seek damages. You’ll likely lose money.
- Seller tries to back out after accepting an offer: Seller can face a lawsuit for specific performance or damages. Sellers should not assume they can cancel without consequence.
Local tips for Milton buyers and sellers (don’t wing it)

- Use a local real estate lawyer: They know Halton Region practices and standard clauses that matter in Milton.
- Keep proof: If you can’t get financing, keep lender communications. If inspection reveals a problem, get a written report.
- Communicate quickly and in writing. Verbal promises don’t help in court.

FAQ — Answering the questions Milton sellers and buyers ask most
How long after signing can a buyer cancel an offer in Milton?
If the offer is conditional, the buyer can cancel up to the condition’s expiry. If unconditional, there is no automatic cancellation window. The timelines are whatever the offer sets (commonly 3–10 business days for standard conditions).
Can a seller cancel after accepting an offer?
Not without consequences. Sellers who back out can face a claim for specific performance (court order to close) or damages. The seller and buyer can, however, agree to a mutual release if both parties consent.
What happens to my deposit if I cancel?
If you cancel under a valid condition, you typically get the deposit back. If you cancel with no contractual basis, the seller can keep the deposit and sue for additional damages.
Is there a cooling-off period for new homes from builders in Ontario?
New home purchases have different rules and protections than resale homes. Some builder contracts have specific rights of rescission and statutory protections via Tarion and other consumer rules. Always get legal advice for new-build contracts.
I missed the condition deadline. Can I still cancel?
Possibly, but it’s harder. Missing the deadline often means the condition is waived. You’ll need to negotiate a mutual release or pursue a legal claim (which is costly and uncertain).
What if I found major undisclosed defects after signing?
If defects were fraudulently concealed or there was material misrepresentation, you may have legal grounds to rescind or claim damages. Get a lawyer and an independent inspection report immediately.
Should I delay signing until I can get legal advice?
If you can, yes. In fast markets you may need to act quickly. At minimum, have a lawyer and mortgage pre-approval in place and make sure your conditions protect you.
Who handles disputes in Milton?
Real estate disputes go to civil court in Ontario. Many issues are resolved through negotiation or mediation first. Always involve a lawyer familiar with Halton Region real estate law.
