What parts of a letter of intent in Ontario actually create enforceable obligations? A letter of intent sets out the framework for a business transaction, but most of its terms are not binding.
Here we explain which provisions typically create real obligations and which ones do not. It also covers why misunderstanding this distinction creates more risk than people expect.
Key Takeaways
- A letter of intent sets out the framework for a transaction. Most of its terms are expressions of intent, not enforceable promises.
- Price, structure, and timing are typically non-binding, even when they are written in specific, detailed language.
- Confidentiality, exclusivity, and sometimes break fees are typically binding and create real legal obligations.
- The main risk is not misunderstanding which terms are binding. It is relying on terms that are not.
- A letter of intent shapes expectations and negotiating dynamics, even in places where it creates no enforceable rights.

What a Letter of Intent in Ontario Actually Does
A letter of intent sits at the start of most business transactions. Before the parties draft a definitive agreement, they typically use a letter of intent to record the deal's basic shape.
This includes the proposed price, the structure of the transaction, and a rough timeline for reaching closing. The letter also often addresses how the parties will conduct due diligence and negotiate the final agreements.
The letter's purpose is to align expectations early. This happens before either party invests significant time and legal fees into drafting a full agreement, signalling serious intent without locking either side into a deal that has not yet been fully investigated.

Binding vs. Non-Binding Provisions in a Letter of Intent
A letter of intent is a mix of binding and non-binding provisions, and the two are often placed side by side in the same document, which is where confusion tends to start.
Non-Binding Terms: Price, Structure, and Timing
Price, structure, and timing are the terms most people focus on, and they are typically non-binding.
Even when a letter specifies a precise purchase price or a detailed structure, these terms are usually expressions of intent rather than enforceable commitments. Either party can generally walk away from these terms, or renegotiate them, once due diligence reveals new information.
This is intentional, as a letter of intent is signed before due diligence is complete. The parties need room to adjust price and structure as they learn more about the business.
Binding Terms: Confidentiality, Exclusivity, and Break Fees
Certain provisions are different. Confidentiality, exclusivity, and sometimes break fees create real, enforceable obligations. This holds true even while the rest of the letter stays non-binding.
A confidentiality provision prevents either party from disclosing sensitive information learned during negotiations. This obligation typically survives even if the deal falls apart entirely.
An exclusivity provision, often called a no-shop clause, stops the seller from negotiating with other buyers for a defined period. This gives the buyer room to complete due diligence without losing the deal to a rival offer.
A break fee provision, where included, requires one party to pay the other a set amount if the deal fails to close. Not every letter of intent includes a break fee, but where one exists, it is typically enforceable.
Why Binding and Non-Binding Terms Get Blurred in Practice
Letters of intent rarely separate binding and non-binding terms into clearly labelled sections. Instead, both types of provisions often appear side by side in the same paragraphs, using similarly firm language throughout.
A letter might state the price in the same firm tone used for the confidentiality clause. If you read quickly, both sentences sound equally binding, while only one of them typically is.
This often isn't an accident, as sellers often want price and structure to feel as firm as possible, even while knowing those terms remain open to change. Buyers, meanwhile, want confidentiality and exclusivity to feel routine rather than heavily negotiated. The result is a document where tone does not reliably signal enforceability.
A well-drafted letter of intent will address this directly. It typically uses a general clause near the end stating which sections are binding and which are not. Reading that clause carefully is the most reliable way to understand what a letter of intent actually commits you to. Do not rely on the tone of individual provisions alone.
The Real Risk of a Letter of Intent: Reliance, Not Misunderstanding
Most people assume the risk in a letter of intent is misunderstanding which terms are binding. In practice, the more common risk is relying on a term that was never binding in the first place.
A buyer might begin arranging financing based on the price stated in the letter of intent, while a seller might turn away other opportunities based on the assumed structure of the deal. Neither of these actions is unreasonable, but neither is protected if that term turns out to be non-binding.
This is why the language in a letter of intent matters as much as its content. A well-drafted letter clearly labels which sections are binding and which are not. This reduces the chance that either party over-relies on a term that was never meant to be enforceable.
How a Letter of Intent Shapes the Deal, Even Without Binding Terms
Even where a letter of intent creates no enforceable rights, it still shapes how the transaction unfolds.
Once signed, a letter of intent becomes the reference point for the rest of the negotiation. Both parties generally expect the final agreement to reflect its terms, even though nothing legally requires that outcome.
This expectation affects leverage. A party trying to move away from the letter's terms later in the process often faces resistance. This holds true even once due diligence is underway, and even if that party has every legal right to change course. The letter creates a psychological and practical anchor that outlasts its lack of enforceability.
This is also why exclusivity provisions matter so much. Most of the letter is non-binding, so the exclusivity period is often the buyer's only real protection. It covers the time and money the buyer invests into due diligence.
What a Well-Drafted Letter of Intent in Ontario Should Include
A letter of intent does not need to cover every detail of the eventual transaction, but it should be clear about a few things.
It should state which sections are binding and which are not, ideally in plain language rather than buried in a general clause. It should set out the proposed price and structure clearly enough to guide the definitive agreement, while also making clear these terms remain subject to negotiation.
It should also address confidentiality and exclusivity directly, since these are the provisions most likely to be enforced. Finally, it should set a reasonable timeline for due diligence and for moving toward a definitive agreement. An open-ended letter of intent can drag on and lose its usefulness.

The Bottom Line on a Letter of Intent in Ontario
A letter of intent is mostly a non-binding document, but that does not make it unimportant. Confidentiality, exclusivity, and sometimes break fees create real obligations. The rest of the letter still shapes how the transaction unfolds.
The real risk is not misunderstanding which terms are enforceable, but relying on terms that were never meant to be.

Frequently Asked Questions
Is a letter of intent legally binding in Ontario?
Parts of it usually are. Confidentiality, exclusivity, and sometimes break fees are typically binding, while price, structure, and timing are usually not.
Why would parties sign a mostly non-binding document?
A letter of intent aligns expectations and signals serious intent. This happens before either party invests significant time and legal fees into a full agreement.
Can the price in a letter of intent change later?
Yes. Price is typically an expression of intent, and it commonly changes once due diligence reveals new information about the business.
What is an exclusivity provision?
An exclusivity provision, also called a no-shop clause, prevents the seller from negotiating with other buyers for a set period.
What is a break fee?
A break fee requires one party to pay the other a set amount if the deal fails to close under conditions defined in the letter.
What happens if I rely on a non-binding term in a letter of intent?
You generally have no legal recourse if that term changes or the deal falls apart. This is why relying on non-binding terms is the main practical risk.
Does a letter of intent affect the final agreement even if it is non-binding?
Yes. It typically becomes the reference point for negotiations. Departing from its terms later often meets resistance, even without a legal obligation to follow them.
What should a well-drafted letter of intent include?
It should clearly separate binding from non-binding sections and state the proposed price and structure. It should also address confidentiality and exclusivity, and set a reasonable timeline for due diligence.
