Commission is the least transparent part of buying a home in Ontario, and it is the one thing almost nobody explains straight. Here is the mechanics, without the sales pitch: where the money comes from, who really pays it, what it buys, and the one part of it a buyer has any leverage over.

Who pays realtor commission in Ontario?

The seller signs the cheque. That is the literal answer, and it is also the answer most buyers have heard from a realtor at some point, usually in a tone that suggests the buyer is getting something for free.

The honest version is less flattering to the industry. A seller pricing their home knows commission is coming out of the proceeds, so it is priced in, the same way any other cost of selling is. The buyer's money pays for the house and everything attached to selling it. So while the seller pays commission in the mechanical sense, the buyer funds it in the economic sense.

That distinction matters because of what follows from it. If commission were genuinely free to buyers, there would be nothing to negotiate and nothing to get back. It is not free, which is exactly why a share of it can come back to you.

How is commission calculated?

Commission is a percentage of the final sale price, agreed in the listing agreement between the seller and the seller's brokerage before the home goes on the market. It is negotiable. It is not set by law, by RECO, or by any real estate board, and any suggestion that there is a mandatory rate is wrong.

In practice, Ontario listings are commonly quoted at around 5% of the sale price in total, and that total is split between the two brokerages involved: the one representing the seller and the one representing the buyer. Around 2.5% typically goes to the buyer's side. Both halves are negotiable, both vary by brokerage and by listing, and lower and higher arrangements are common.

Two things people get wrong here. First, the percentage applies to the whole sale price, not the seller's equity, so the dollar amount grows with the market whether or not the work does. Second, the money goes to the *brokerages* first, not directly to the individual agents, and how it is then split with an agent is a separate arrangement inside each brokerage.

the commission total commonly quoted on Ontario listings, split between the seller's and buyer's brokerages. It is negotiable, and always set in the listing agreement rather than by any regulator.

If you want the arithmetic on a specific price rather than a percentage, our realtor commission calculator does it on the actual numbers.

What does the commission actually pay for?

On the seller's side, it covers pricing and listing strategy, photography and marketing, MLS exposure, showings, negotiation, and the paperwork through to closing.
