Most letters of intent (LOIs) for an Ontario business purchase are, on the whole, not legally binding — the price and most commercial terms can still change before a definitive agreement is signed. But a handful of specific provisions inside that same LOI are often drafted to bind the parties immediately, and the exclusivity clause, sometimes called a "no-shop" clause, is usually one of them.
If you're a buyer, an exclusivity clause is one of the few real protections you get at the LOI stage — but it isn't automatic, and it doesn't last forever. If you're a seller, agreeing to one means giving up options while due diligence and negotiation play out. Understanding what you're actually agreeing to avoids surprises on either side.
What an Exclusivity Clause Does
An exclusivity clause is a promise, usually made by the seller, not to:
- solicit, negotiate with, or accept offers from other prospective buyers,
- provide due diligence materials to anyone else, or
- sign a competing letter of intent or agreement,
for a defined period after the LOI is signed. It's typically one of the few provisions in an otherwise non-binding LOI that's drafted to be enforceable on its own, separate from whether the deal itself ever closes.
What the Buyer Gets
For a buyer, exclusivity buys time and certainty to invest in the deal without a competing bidder appearing partway through:
- Confidence to spend money on lawyers, accountants, and other advisors for due diligence.
- Room to negotiate the definitive purchase agreement without a rival offer forcing a rushed decision.
- Leverage if the seller tries to renegotiate price upward mid-process — the seller has already agreed not to shop the deal elsewhere.
Exclusivity doesn't, by itself, guarantee the deal will close. It only limits what the seller can do with other potential buyers while the buyer works toward a definitive agreement.
What the Seller Gives Up
A seller who agrees to exclusivity is taking a real risk in exchange for that certainty:
- Lost market opportunity. If a better offer appears during the exclusivity period, the seller generally can't pursue it without breaching the clause.
- Time pressure. If the buyer walks away — or drags out the process — near the end of the exclusivity period, the seller has lost that window and may need to restart marketing the business.
- Limited recourse if the buyer isn't serious. Exclusivity restrains the seller, not the buyer's pace; a buyer who simply negotiates slowly, without breaching anything, can still tie up the seller's options.
Sellers can — and should — negotiate the scope and length of exclusivity rather than accepting a buyer's first draft.
Common Terms Worth Negotiating
| Term | What it addresses |
|---|---|
| Length of the exclusivity period | How long the seller is restricted before it can talk to other buyers again |
| Carve-outs | Whether the seller can still respond to unsolicited offers, or must actively refuse to even discuss them |
| Extension mechanics | Whether exclusivity can be extended, and by whom, if the deal is close but not finished |
| Consequences of breach | What remedy the buyer has if the seller breaches — sometimes tied to a separate cost-reimbursement provision |
| Scope | Whether it covers only the seller, or also directors, officers, and other shareholders who could otherwise field competing offers |
Frequently asked questions
Is an exclusivity clause always enforceable even if the rest of the LOI isn't binding?
Generally, yes — that's usually the point of drafting it as a standalone binding provision. Courts have recognized that parties can make specific clauses binding within an otherwise non-binding document, but the exact wording of your LOI controls. Have a lawyer confirm what's actually binding before you sign.
What happens if a seller breaches exclusivity?
It depends entirely on what the LOI says. Some LOIs specify a cost-reimbursement obligation, others simply expose the seller to a claim for damages the buyer can prove. This is a case where the drafting really matters — don't assume a remedy exists if the clause doesn't spell one out.
Can a seller negotiate a shorter exclusivity period than what the buyer first proposes?
Yes, and sellers often should. A shorter period with a clear extension mechanism, used only if both sides are working in good faith, protects the seller's options better than an open-ended or unusually long exclusivity period.
Does exclusivity mean the deal will definitely close?
No. Exclusivity only restricts the seller's ability to talk to other buyers — it says nothing about whether the buyer will ultimately proceed to a definitive agreement and closing.
