How to Draft a Finder’s Fee Agreement for M&A Brokers in Ontario

27 Jun 2026 5 min read No comments Business Formation & Contracts Ontario

In Ontario, a Finder’s Fee Agreement compensates a business broker for introducing a buyer or seller in a Mergers and Acquisitions (M&A) deal. A well-drafted contract relies on the “Lehman Formula” or a flat percentage to calculate the payout, and legally requires a strict “tail period” clause to protect the broker’s commission if the deal closes months later.

Selling a successful business or acquiring a new competitor is a complex journey. 💼 In cities like Toronto, Hamilton, and Ottawa, many business owners rely on corporate brokers or M&A advisors to connect them with lucrative buyers. These intermediaries do not work for free; their compensation hinges entirely on making a successful introduction that leads to a closed transaction.

To ensure everyone is treated fairly, it is critical to lock in a formal Finder’s Fee Agreement before any sensitive corporate data changes hands. Without a written contract, brokers risk being cut out of their commission by sneaky buyers and sellers who try to close the deal privately. This guide breaks down how to draft a legally binding, bulletproof finder’s fee contract under Ontario corporate law as of May 2026.

Step-by-Step Process in Ontario

Creating a finder’s fee arrangement is about clearly defining what constitutes a successful “introduction” and exactly how the math works on closing day. 📝 Most law firms will guide you through this specific process to prevent future litigation.

Step 1: Identify the Parties and Define the “Introduction”

The contract must name the business owner (the client) and the broker (the finder). More importantly, it must explicitly define what counts as a valid introduction. Simply sending an email to a potential buyer is rarely enough. A standard agreement will state that the finder must arrange a formal meeting or secure a signed Non-Disclosure Agreement (NDA) from a qualified prospect to officially register them as an “introduced party.”

Step 2: Choose the Compensation Structure

How will the broker be paid? 💰 You generally have two choices. The first is a flat percentage (e.g., 5% of the total enterprise value upon closing). The second, heavily favored in larger corporate M&A deals, is the Lehman Formula. The classic Lehman Formula works on a sliding scale: 5% of the first million dollars, 4% of the second million, 3% of the third million, 2% of the fourth million, and 1% of everything above that.

Step 3: Define the Total Transaction Value

It is crucial to define exactly what the percentage or formula is applied to. Does “Transaction Value” just mean the cash paid on closing day? In a properly drafted Ontario agreement, Transaction Value includes all cash, assumed debt, seller financing (promissory notes), and the value of any retained shares. This ensures the broker gets a fair cut of the total economic benefit, not just the upfront cash.

Step 4: Establish the “Tail Period” Protection

This is the most critical clause for the broker. ⏱ M&A deals can take months or years to close. A “tail period” (often 12 to 24 months) dictates that if the broker’s contract expires or is terminated, but the client ends up selling the business to a party the broker originally introduced within that tail period, the broker is still legally entitled to their full commission.

Step 5: Include Non-Circumvention and Confidentiality Clauses

Before the broker shares the Confidential Information Memorandum (CIM) or the identity of the seller, the buyer must be legally bound not to bypass the broker. The agreement must clearly state that the buyer cannot approach the seller directly or attempt to hire their employees, ensuring the broker remains the mandatory intermediary for the transaction.

How Much Does it Cost in Ontario?

The upfront legal costs of drafting the agreement are minimal compared to the massive commission at stake. 💵 Here is what you should expect regarding financial outlays:

  • Legal Drafting Fees: Having a corporate lawyer draft or heavily review a Finder’s Fee Agreement usually costs between $800 CAD and $2,500 CAD.
  • The Broker’s Commission: For small to mid-market businesses (under $5 Million CAD), flat fees of 5% to 10% are common. For larger enterprises, the Lehman Formula (or the modern “Double Lehman”) usually yields an effective fee of 2% to 4% of the total deal value.
  • Taxes: Under Canadian law, finder’s fees are considered a service and are subject to 13% HST in Ontario, which must be added to the final payout on closing day.

How Long Does the Process Take?

Drafting and negotiating the agreement itself is relatively fast. 📅 A good corporate lawyer can prepare a solid draft in 3 to 7 business days. However, the actual payout of the fee takes much longer. A typical M&A transaction in Ontario takes anywhere from 6 to 12 months from the signing of the Finder’s Fee Agreement to the final closing date when the cheque is actually cut.

$1,000,000$50,000$50,000
$3,000,000$120,000 (5% + 4% + 3%)$150,000
$5,000,000$150,000$250,000
$10,000,000$200,000$500,000

Frequently Asked Questions (FAQ)

What happens if the deal falls through at the last minute?

Generally, a finder’s fee is strictly contingent upon a successful closing. If the buyer backs out during the due diligence phase or the financing falls through, the transaction is dead, and the broker does not receive a commission. Most contracts explicitly state “payable upon successful completion.”

Does a business broker need a real estate license in Ontario?

It depends on the assets being sold. If the M&A deal involves the transfer of actual real estate (land or buildings), the broker must be registered under the Trust in Real Estate Services Act (TRESA). If it is purely a share sale with no real property involved, a specialized license may not be legally required, but using experienced professionals is always recommended.

What is a “Double Lehman” formula?

Because inflation has heavily impacted business valuations, many brokers now ask for the “Double Lehman.” This simply doubles the classic percentages: 10% on the first million, 8% on the second, 6% on the third, 4% on the fourth, and 2% on everything above. It is widely used in smaller, lower-mid-market transactions.

Can the seller pay the finder’s fee in shares instead of cash?

Yes. While cash is king, it is entirely possible to draft the agreement so that the broker takes a portion of their fee in equity (shares in the newly formed or acquiring company). However, this must be clearly outlined in the agreement and evaluated for tax implications with the CRA.
