How Much Does a Realtor Cost in Ontario? (And How to Keep That Money)

Before you sign anything with a realtor in Ontario, you need to know one number: $45,200. That's what a standard 5% commission costs on an $800,000 home, including HST. Most Ontario homeowners don't find out until they're sitting at the closing table, watching a significant chunk of their equity disappear.

The question of how much a realtor costs in Ontario isn't just about the percentage. It's about understanding exactly what you're paying for, who gets it, and whether there's a better option for your situation. In a province where the average home price hovers around $725,000, even a fraction of that commission adds up to real money that belongs in your pocket, not someone else's.

This guide breaks down exactly what realtor commission costs in Ontario, what you actually get for it, and what your alternatives are.

How Much Does a Realtor Cost in Ontario? The Real Numbers

Ontario Real Estate Commission is entirely negotiable, but in practice, most transactions follow a familiar structure.

The typical benchmark is 3.5% to 5% of the sale price, plus 13% HST. This commission is usually split between the listing agent (the realtor representing you as the seller) and the buyer's agent (the realtor representing the buyer). Each side typically takes 2% to 2.5%.

Here's what that looks like in real numbers:

• $600,000 home — 5% commission = $30,000 + $3,900 HST = $33,900

• $800,000 home — 5% commission = $40,000 + $5,200 HST = $45,200

• $1,100,000 home (GTA average) — 5% commission = $55,000 + $7,150 HST = $62,150

These figures come directly from your sale proceeds at closing. You don't write a cheque, but you absolutely feel it in your net return.

The non-obvious insight most sellers miss: Commission is calculated on the gross sale price, not your equity. If you own $400,000 in equity on an $800,000 home, you're paying $45,200 in commission on the full $800,000, meaning that commission consumes over 11% of your actual equity. That's a very different number than 5%.

What Does a Realtor in Ontario Actually Do for That Commission?

This is the question most Ontario homeowners never ask until it's too late. Understanding what you're paying for helps you decide what you actually need.

A listing agent in Ontario typically provides:

• Comparative market analysis (CMA) — a pricing report based on recently sold data

• MLS listing — posting your home on Realtor.ca through the MLS system

• Professional photography — usually included, sometimes outsourced

• Showings coordination — scheduling and sometimes hosting viewings

• Offer management — presenting and negotiating offers on your behalf

• Paperwork — preparing and reviewing the Agreement of Purchase and Sale

Here's the reality: several of these services are available independently for a fraction of the cost.

A professional appraisal costs $300–$500. Professional photography runs $150–$300. A flat-fee MLS listing through a service like a discount brokerage costs $300–$500. A real estate lawyer reviews your APS for $1,200–$1,800.

Add all of that up, and you're spending roughly $2,500–$3,000 to replicate the core services, compared to $45,200 in full commission on an $800,000 home. The math is hard to ignore.

The FSBO Formula Pro Toolkit ($297) gives Ontario homeowners everything they need to handle pricing, marketing, and negotiation privately at a fraction of the cost of a listing agent.

Who Actually Pays Realtor Commission in Ontario?

This is one of the most misunderstood aspects of Ontario real estate, and understanding it changes how you approach selling privately.

Technically, the seller pays the entire commission. Even the buyer's agent commission is paid from the seller's proceeds. The buyer doesn't pay their agent directly; you do, as part of the sale.

This means when you list with a traditional agent at 5%, you are paying:

• 2% to 2.5% to your listing agent

• 2% to 2.5% to the buyer's agent

As a private seller, you eliminate the listing side entirely. You save the full 2%–2.5% listing commission automatically. The question then becomes whether to offer a cooperating commission to buyer's agents.

Under Ontario's TRESA regulations, you are not legally obligated to offer buyer's agents anything. However, offering 2%–2.5% to cooperating buyer's agents keeps your listing accessible to the majority of active buyers who are represented by an agent. A Mississauga homeowner who sold privately in 2025 chose to offer 2% to buyer's agents; she saved $18,000 compared to paying full commission on both sides, while still attracting four competing offers within two weeks.

This is exactly the kind of strategic decision the FSBO Formula free guide walks you through, so you understand every option before committing to anything.

How to Avoid Paying Full Realtor Commission in Ontario

There are several legitimate paths Ontario homeowners are choosing to reduce or eliminate realtor commission. Each has trade-offs worth understanding.

Option 1. Full FSBO (For Sale By Owner)

You handle everything yourself: the pricing, marketing, showings, negotiations, and closing. Maximum savings, maximum effort. Works best for homeowners who are organised, confident negotiators, and have time to manage the process. The FSBO Formula toolkit system is built specifically for this path.

Option 2. Flat-Fee MLS Listing

You pay a flat fee ($300–$500) to a discount brokerage to list your home on MLS/Realtor.ca. You still handle showings and negotiations yourself, but you get MLS exposure. You may still choose to offer buyer's agent commission. Saves the full listing-side commission.

Option 3. Expert Matching with Flat-Fee Professionals

Not ready to go fully solo? FSBO Formula's Expert Matching service connects Ontario homeowners with verified flat-fee real estate professionals who provide specific service like MLS listing, offer review, or negotiation support for a set fee rather than a percentage. You get professional help without paying 5%.

Option 4. Negotiate Commission Directly

If you prefer working with a traditional agent, commission is always negotiable. In Ontario's current balanced market, many agents will accept 3%–4% rather than lose the listing. Always negotiate before signing any listing agreement.

Objection handled: "What if I price it wrong without an agent?"

This is the most common concern and it's valid. But pricing tools have never been more accessible. HouseSigma gives free access to real Ontario sold data. A professional appraisal for $300–$500 gives you a defensible number. The FSBO Formula pricing matrix walks you through a comparable analysis step by step. Pricing incorrectly is a risk, but it's a manageable one with the right tools.

The Hidden Costs Most Ontario Sellers Don't Factor In

Commission is the highest cost, but it's not the only one. Here's a complete picture of what Ontario sellers actually pay at closing:

Costs every seller pays regardless of how they sell:

• Real estate lawyer: $1,200–$1,800

• Mortgage discharge fee (if applicable): $200–$400

• Moving costs: variable

• Property tax adjustment: variable (depends on closing date)

• Home staging (optional but recommended): $500–$2,000

Costs you pay if using a traditional agent:

• Listing agent commission: 2%–2.5% + HST

• Buyer's agent commission: 2%–2.5% + HST

• Total commission: 4%–5% + HST

Costs if selling privately:

• Flat-fee MLS listing: $300–$500

• Professional photography: $150–$300

• Professional appraisal (recommended): $300–$500

• FSBO Formula toolkit: $47–$697 depending on tier

The difference on an $800,000 Ontario home:

• Traditional sale total commission cost: ~$45,200

• Private sale total additional costs: ~$1,500–$2,000

• Net savings by selling privately: $43,000–$43,700

Objection handled: "Is this too complicated for me?"

The paperwork, the legal process, the negotiations, none of it is beyond what a motivated Ontario homeowner can handle with the right resources. Thousands of Ontario homeowners sell privately every year without incident. The process has steps, but every step is learnable. The FSBO Formula system exists precisely because the process doesn't need to be complicated; it just needs to be organised.

Understanding how much a realtor costs in Ontario is the first step toward making a fully informed decision about one of the biggest financial transactions of your life. The commission structure is real, the alternatives are legitimate, and the savings are significant. Whether you choose to sell fully privately, use a flat-fee service, or get matched with a flat-fee professional, you have more options than the traditional real estate industry would have you believe.
