Commercial Real Estate Commission in Ontario: What Sellers Need to Know
Commercial real estate commission in Ontario is not set by law or by a published standard rate; it is negotiated between the seller and the brokerage and recorded in a written listing agreement. For sellers, the useful questions are therefore not “what is the going rate?” but “how is this fee structured, what does it include, when is it earned, and what happens if the property does not sell?” This guide explains the common structures, the terms that matter more than the headline percentage, and how to compare proposals from different brokerages on equal footing.

Commission Is Negotiable
There is no fixed commission for commercial property in Ontario. The amount and structure depend on the size and complexity of the property, the scope of services, the expected marketing effort and the arrangement between the parties. Be cautious about any source that quotes a single “standard” percentage for all commercial sales. Ask each brokerage to explain how they arrived at their proposal and what you receive for it.
Common Commission Structures
- Percentage of the sale price: the most familiar structure, sometimes tiered so the percentage falls as the price rises.
- Flat fee: a fixed dollar amount regardless of price, more common in simple or lower-value deals.
- Minimum fee: a percentage with a floor, protecting the brokerage on lower-priced sales.
- Performance-based or incentive components: a higher rate on price above an agreed target, aligning the brokerage’s interests with yours.
- Split with the buyer’s brokerage: the listing agreement should say how any cooperating brokerage is compensated, so you know the total you will pay.
Whatever the structure, ask for the total dollar cost at several different sale prices so you can compare proposals like for like.
The Terms That Matter as Much as the Rate
- Scope of services: valuation, marketing materials, buyer outreach, negotiation, due diligence support and closing coordination. A lower fee for fewer services is not necessarily a better deal.
- Term of the listing: how long you are committed to the brokerage.
- When the commission is earned: on a signed agreement, on removal of conditions, or on closing.
- Holdover or tail provisions: a period after the listing expires during which the brokerage may still claim a fee if the property sells to a buyer they introduced.
- Termination rights: how you can exit if the relationship is not working.
- Marketing expenses: whether the brokerage pays them or passes them on to you.
- Treatment of HST: commission is generally subject to HST, so confirm whether quoted amounts include it.
How to Compare Proposals
Ask each brokerage for the same items in writing: the fee at three or four possible sale prices, the services included, the marketing plan, recent comparable assignments, and the listing agreement terms above. Then compare the expected net result, not just the fee. A brokerage that can credibly reach more qualified buyers or run a stronger process can produce a better net outcome even at a higher fee, and a lower fee with weak execution can cost far more than it saves.

Other Costs of Selling
Commission is one of several selling costs. Others can include legal fees, environmental reports, surveys, appraisals, repairs or credits negotiated in due diligence, mortgage discharge penalties, and taxes. Income tax on any gain and HST considerations should be reviewed with your accountant. The buyer, not the seller, ordinarily pays Ontario land transfer tax, but it affects buyers’ budgets: the non-residential provincial brackets are 0.5% to $55,000, 1.0% to $250,000, 1.5% to $400,000 and 2.0% above.
Get It in Writing and Have It Reviewed
The listing agreement is a legal contract. Read it in full, ask questions about every clause you do not understand, and have your lawyer review it before you sign. Make sure that any verbal promises about services, marketing or fee flexibility appear in the document.
