How much commission does a business broker charge in Canada?
Business brokers are paid mainly by a commission on the sale price, paid at closing. The International Business Brokers Association (IBBA), a US-based association, says business broker commissions on Main Street sales can range from 8% to 15% of the final sale price and may be subject to an agreed minimum (IBBA, Your Guide to the Business Brokerage Profession, 2021). No Canadian survey of broker commissions is cited here, so treat that range as a reference point and compare written quotes.
Typical Commission Rates in Canada
For smaller transactions, the standard commission structure is straightforward: a percentage of the final sale price. Most brokers work on a success-fee basis, meaning they're paid only when the transaction closes. Commission is usually deducted from the sale proceeds at closing.
Many brokers set a minimum fee that applies regardless of transaction size. This protects brokers on very small deals where a straight percentage wouldn't justify the work involved; ask for the amount in writing.
Some brokers charge an upfront fee, for example for a Broker Opinion of Value, which is then applied against the closing commission (IBBA, Your Guide to the Business Brokerage Profession, 2021). Monthly retainers are more common among M&A advisors on larger deals than among business brokers.
How Commission Structures Vary by Deal Size
On larger deals, brokers and advisors often use the Lehman Formula, a sliding scale that reduces the percentage as the deal size increases. The classic Lehman Formula charges 5% of the first $1 million, 4% of the second million, and so on down to 1%; "Double Lehman" starts at 10% and falls to 2% (Firmex, Global M&A Fee Guide 2024-25).
Check what the commission is calculated on: the total price including assumed debt and seller financing, or only the cash you receive at closing. The difference can be large, so get it in writing.
What's Included in the Commission
Full-service broker fees commonly include business valuation, marketing materials, buyer qualification, negotiation support, and transaction coordination. The broker handles the listing process, screens potential buyers, manages showings, and coordinates with lawyers and accountants through closing.
Exclusive listing agreements typically run 6–12 months, with broker commission protection extending 6–12 months after the agreement terminates for any buyers introduced during the listing period. This tail provision protects brokers if a seller tries to circumvent the commission by waiting out the listing term before closing with a broker-introduced buyer.
Negotiating Broker Fees
Commission rates are generally negotiable, especially on larger transactions. Sellers can sometimes negotiate lower rates by offering exclusivity, longer listing periods, or by bringing the broker a pre-qualified buyer.
The quality of the broker's work matters more than the percentage difference in most cases. A skilled broker who closes the deal at a higher valuation will net the seller more than a discount broker who underprices the business or fails to close.
Regional Variations Within Canada
Ontario and British Columbia have the highest concentration of business brokers and the most competitive fee structures. In these markets, sellers have more options and can often negotiate more favorable terms.
Brokers in rural or smaller markets may charge higher percentage rates due to longer marketing periods and smaller deal volumes. The effort required to market and sell a business in a smaller community is often comparable to urban deals, but the transaction size may be lower.
Business broker commissions are subject to GST/HST as a taxable professional service — budget for this on top of the commission rate. Note: the going concern exemption under Canadian tax law applies to the sale price of the business itself, not to the broker's service fee.
