"I just don't want to do this deal anymore" is not, on its own, a legal ground to walk away from a signed business purchase agreement. Once both sides sign, Ontario contract law treats the agreement as binding — and a party who terminates without a legitimate basis exposes themselves to a breach of contract claim, not a clean exit.

That said, real, enforceable exit routes do exist in most agreements. The question is always the same: does your agreement, on its actual wording, give you a right to terminate in this situation? This article walks through the grounds that generally hold up, the ones that generally don't, and how to tell the difference before you act.

Grounds That Generally Work

Unsatisfied conditions precedent

Most purchase agreements are conditional — closing depends on things like financing approval, satisfactory due diligence, landlord consent to a lease assignment, or regulatory/licensing approval. If a condition genuinely isn't satisfied (or waived) by its deadline, and the agreement is drafted so that failure entitles a party to terminate, that's typically a valid, contractually built-in exit. This is very different from simply losing enthusiasm for the deal — the condition has to have actually failed on its own terms.

Material breach by the other party

If the other side breaches an important term of the agreement — a seller who fails to provide required financial disclosure, for example, or who takes actions expressly prohibited during the pre-closing period — the non-breaching party may have grounds to terminate, particularly where the agreement lists specific breach-based termination rights or where the breach goes to the heart of the deal.

A properly drafted "material adverse change" clause, if triggered

Some agreements include a clause allowing a party (usually the buyer) to walk away if the target business suffers a material adverse change between signing and closing. These clauses are typically narrow and carefully worded, carving out routine or industry-wide fluctuations. Whether a specific event actually triggers the clause is a fact-heavy question that needs direct legal review — don't assume a downturn in sales or a lost customer automatically qualifies.

Mutual agreement

The parties can always agree to terminate — this is the cleanest exit of all, and it's why a candid conversation between the parties (through counsel) is often worth attempting before assuming litigation is the only path.

Misrepresentation discovered before closing

If, before closing, the buyer discovers the seller made a representation in the agreement (or in disclosure materials) that was false in a way that matters, this can support termination depending on how the representation and warranty provisions are drafted, and how serious the misrepresentation is.

Grounds That Generally Don't Work

ExcuseWhy it usually fails
"I found a better deal elsewhere"Not a legal ground; the agreement remains binding regardless of alternatives
"The market changed" or "I'm having second thoughts"Buyer's remorse is not a contractual right to terminate
"I can't get financing" (but never actually applied)Financing conditions typically require genuine effort, not a token attempt or none at all
"The other side won't renegotiate the price"A refusal to renegotiate isn't a breach — the original terms remain enforceable
"Closing is inconvenient right now"Timing preferences aren't a recognized termination ground absent a specific clause addressing it
"I signed too fast and didn't read it properly"Ontario courts generally hold parties to contracts they signed, absent fraud, duress, or another recognized vitiating factor

How to Assess Your Own Situation

  1. Pull out the actual purchase agreement — not your memory of the deal, and not the letter of intent that preceded it (LOIs are usually non-binding on the commercial terms, even if certain provisions inside them are binding).
  2. Identify every condition and termination clause and check its precise wording against your facts.
  3. Confirm timing — many termination and condition clauses have strict deadlines; missing one can forfeit the right to rely on it.
  4. Document your basis in writing, especially if you're relying on a breach or a material adverse change — vague or undocumented claims are far weaker if challenged.
  5. Get the clause reviewed by a lawyer before acting on it — terminating on a ground that turns out to be invalid can itself become a breach, reversing your legal position from the wronged party to the one exposed.

What Happens If You Terminate on Invalid Grounds

Terminating without a valid legal basis is treated as a repudiation of the contract — effectively, an anticipatory breach. The other party can typically respond by accepting the repudiation and suing for damages, or in some cases pursuing specific performance to force the deal through. Deposits, break fees, and cost-recovery clauses in the agreement may also come into play against the party who terminated improperly. This is why it matters so much to confirm your ground is real before invoking it, not after.

Frequently asked questions

Can I terminate just because I changed my mind?

No — a change of heart, on its own, is not a legal ground to terminate a signed purchase agreement. You need a basis the agreement or the general law actually recognizes, such as an unsatisfied condition or the other party's breach.

What's the difference between terminating and simply not closing?

There isn't a meaningful legal difference — refusing to close without a valid ground is a breach whether or not you use the word "terminate." The other party can pursue the same remedies either way.

Does the letter of intent give me a right to walk away later?

Generally no, once a definitive purchase agreement has been signed — the LOI is typically superseded, except for provisions the parties expressly agreed would survive (confidentiality or exclusivity, for example). Your termination rights come from the purchase agreement itself.

Should I just try to negotiate instead of terminating?

Often, yes. Even where a valid ground exists, a negotiated exit, price adjustment, or extension can be faster and less costly than a formal termination fight, especially if both sides would rather avoid litigation. A lawyer can help you weigh which path actually serves your interests.
