Understanding Letters of Intent in Canadian M&A Transactions

Before the detailed negotiations that lead to a definitive purchase agreement, most mergers and acquisitions transactions begin with a letter of intent. Commonly referred to as an LOI, this document sets out the key terms and conditions that the parties have agreed to in principle, creating a framework for the negotiations and due diligence process that follow. While letters of intent are a standard feature of M&A transactions in Canada, they are often misunderstood. Business owners sometimes treat them as informal or non-binding in their entirety, which can lead to unexpected legal obligations and disputes.

What Is a Letter of Intent in M&A?

A letter of intent is a preliminary document that outlines the principal terms of a proposed transaction between a buyer and a seller. It is typically signed after initial discussions have established mutual interest but before the parties commit the significant time and expense required for full due diligence.

The LOI serves several practical purposes. It confirms that the parties are aligned on the fundamental terms of the deal, such as the purchase price, the structure of the transaction, and the anticipated timeline. It also provides the buyer with a degree of certainty that the seller will not engage with other potential buyers during the due diligence period.

Binding vs. Non-Binding Provisions

One of the most common misconceptions about letters of intent is that they are entirely non-binding. In practice, most LOIs contain a mix of binding and non-binding provisions, and the distinction between the two is critically important.

Non-Binding Provisions

The core commercial terms of the LOI — such as the purchase price, the proposed deal structure, the scope of assets or shares being acquired, and the anticipated closing date — are typically expressed as non-binding. This gives both parties the flexibility to adjust terms as more information becomes available during due diligence.

Binding Provisions

Certain provisions in an LOI are typically expressed as binding, meaning they create enforceable legal obligations even if the transaction ultimately does not proceed. Common binding provisions include exclusivity (no-shop) clauses, confidentiality obligations, expense allocation terms, and governing law and dispute resolution clauses.

Exclusivity clauses are one of the most significant binding commitments in an LOI. They prevent the seller from soliciting or entertaining offers from other potential buyers for a specified period, usually ranging from 30 to 120 days.

Key Terms to Negotiate Carefully

Purchase Price and Payment Terms

The LOI should clearly state the proposed purchase price and how it will be paid — whether entirely in cash at closing, or with a portion deferred through vendor take-back financing, earnout arrangements, or holdbacks.

Due Diligence Scope and Timeline

The LOI should set out the scope and timeline of the buyer's due diligence investigation. Buyers need provisions broad enough for a thorough investigation, while sellers benefit from reasonable parameters that prevent overly intrusive or prolonged reviews.

Conditions to Closing

While the definitive agreement will contain detailed conditions to closing, the LOI typically identifies the major conditions at a high level. These might include satisfactory completion of due diligence, receipt of required regulatory approvals, execution of employment or non-competition agreements with key personnel, and receipt of required third-party consents.

Break Fees and Termination Rights

Some LOIs include provisions for break fees — payments that one party must make to the other if the transaction does not proceed for specified reasons. The LOI should also address the circumstances under which either party can terminate.

Recent Developments in Canadian Law

Canadian courts have continued to clarify the legal significance of LOIs and other preliminary deal documents. Recent decisions have reinforced that courts will look at the substance of the agreement — not just its title or the parties' stated intentions — to determine which provisions are enforceable.

This means that imprecise language in an LOI can have unintended consequences. These developments underscore the importance of having your LOI drafted or reviewed by legal counsel who understand M&A practice.

Protecting Your Interests

Whether you are a buyer or a seller, the letter of intent in an M&A transaction is your first opportunity to shape the transaction on terms that reflect your priorities. Taking the time to negotiate a well-drafted LOI — with clear distinctions between binding and non-binding provisions — sets the stage for a more efficient and predictable deal process.

If you are entering into M&A discussions and need guidance on structuring or reviewing a letter of intent, engaging legal counsel experienced in M&A transactions early in the process helps ensure that your LOI protects your interests and provides a solid foundation for the transaction ahead.
