Yes. You can sell a house without a real estate agent in Ontario. The province does not require a seller to hire a licensed agent, so you are free to price, list, show, and negotiate the sale on your own. The one professional you cannot skip is a real estate lawyer, who is needed to close any property transfer in Ontario.
Selling on your own is usually called a private sale, or FSBO, which is short for "for sale by owner." Real estate in the province is regulated under the Trust in Real Estate Services Act, known as TRESA, and administered by the Real Estate Council of Ontario, or RECO. Those rules govern licensed agents and brokerages. They do not force a homeowner to use one. If a buyer comes to you with their own agent, TRESA treats you as a self-represented party, meaning that agent works for the buyer and not for you.
The biggest practical hurdle is exposure. Only a registered brokerage can post a listing to the Toronto Regional Real Estate Board MLS system and to Realtor.ca, where most buyers and their agents look first. Private sellers get around this by paying a flat fee to a "mere posting" brokerage, which places the home on MLS while the seller handles the rest. Even then, most private sellers still offer the buyer's agent a commission, often around 2 to 2.5 percent, because few buyer agents will bring clients to a listing that pays them nothing.
That offer is where the savings shrink. A full-service Ontario sale usually runs 4 to 5 percent of the price plus HST, split between the listing side and the buying side. Selling privately can remove the listing-side portion, but the buyer-side commission and the tax often remain. You also absorb the work an agent would normally carry: setting a defensible price, marketing the home, running showings, and preparing the Agreement of Purchase and Sale without errors. Your disclosure duties about the property do not disappear because you sold it yourself.
Before deciding, weigh the commission you might save against a smaller buyer pool and the hours the process demands.
