Why You Need Your Own Agent When Buying a Home

There’s a fundamental thing about real estate transactions in Ontario that a lot of buyers don’t understand until it’s too late: the listing agent works for the seller. Not for you. Not for “both sides.” For the seller. Their legal obligation — their fiduciary duty — is to get the seller the best possible price and terms. That’s their job.

So when you walk into an open house and the listing agent is being friendly, answering your questions, and making you feel like they’re on your side — they might be perfectly nice. But they are not your advocate. And in a transaction involving the biggest purchase of your life, you need an advocate.

What fiduciary duty actually means

This isn’t just theoretical. Under Ontario’s Trust in Real Estate Services Act (TRESA), agents have specific legal obligations to their clients. For the listing agent, that means loyalty to the seller, confidentiality about the seller’s motivations, and a duty to get the best deal for the seller.

So what does that look like in practice? Say you’re a buyer at an open house and you tell the listing agent, “We love this place. Our budget is $1.1 million but we’d go up to $1.2 million if we had to.” You’ve just handed the seller’s agent your playbook. They now know your ceiling. And their obligation is to their client — the seller — not to you.

When you have your own buyer representative, that conversation is protected. You can tell your agent your absolute maximum, your strategy, your concerns, and it stays confidential. Your agent’s fiduciary duty is to you. They can’t disclose your motivations to the other side. That’s not just good practice — it’s the law.

The negotiation gap

Here’s where it gets real. I’ve been involved in hundreds of transactions across Toronto, York Region, and beyond. And I can tell you that the difference between a well-negotiated deal and a poorly negotiated one is often $20,000 to $50,000. Sometimes more.

That gap comes from knowing things. Knowing that the seller has already bought another property and needs to close by a certain date — so you can use your closing date as a negotiation tool instead of just offering more money. Knowing that the property has been on the market for 45 days and the seller is getting anxious. Knowing that comparable homes on the same street sold for 5% less six months ago, which tells you the asking price is aggressive.

A buyer’s agent gathers this intelligence. They call the listing agent, they pull the data, they read the market context. And then they use all of that to negotiate on your behalf. Without that, you’re flying blind. You’re essentially hoping the other side will be fair, and — I say this with respect to listing agents, many of whom are excellent — hoping isn’t a strategy.

Access to data you can’t get on your own

Realtor.ca and other public sites show you what’s currently listed. What they don’t show you is what matters most: what properties have actually sold for, how long they sat before selling, whether prices were reduced, and what the trends look like over the past 6 to 12 months in a specific neighbourhood.

As a buyer’s agent, I have access to the full MLS database — including sold data, days on market, price history, and neighbourhood-level statistics. When a client asks me whether $950,000 is a fair price for a townhouse in Thornhill, I’m not guessing. I’m pulling every comparable sale within a reasonable radius over the past three to six months, adjusting for differences in size, condition, and lot, and giving them an actual data-backed answer.

I think the era of information asymmetry in real estate has shrunk a lot — buyers have more information now than ever before. But there’s still a significant gap between what’s publicly available and what an agent working for you can provide. And that gap is biggest exactly when the stakes are highest: during negotiations and in competitive situations.

Protection through the entire process

Buying a home isn’t just about making an offer. After the offer is accepted, there’s a whole process — financing conditions, home inspection, title search, insurance, lawyer review, closing. At every step, things can go sideways. The appraisal comes in low. The inspection reveals a structural issue. The title search shows an encroachment from the neighbour’s fence.

Your buyer’s agent quarterbacks all of this. They coordinate with your mortgage broker, your lawyer, and the listing agent. They make sure deadlines are met — and in real estate, missing a condition date can mean waiving your right to that condition entirely. That’s not a small thing. If you miss your inspection condition deadline by one day, you could be legally committed to buying a property with a cracked foundation.

I’ve had deals where the inspection turned up something serious and we had to go back to the seller and renegotiate. Having done this many times, I know what’s reasonable to ask for and what’s going to kill the deal. That experience matters. A buyer without representation is guessing at best and getting taken advantage of at worst.

What about dual agency?

Sometimes buyers ask: “Can’t the listing agent just represent me too? They already know the property.” In Ontario, this is called “multiple representation” and it’s legal under TRESA — but I think it’s a terrible idea for buyers, and I’ll tell you why.

When one agent represents both the buyer and the seller, they can’t fully advocate for either side. They can’t advise the seller to reject your offer because it’s too low. They can’t advise you to push harder on price because the seller is desperate. They become a neutral facilitator instead of an advocate. And in a negotiation where hundreds of thousands of dollars are on the line, neutral is not what you want.

I think of it like this: would you want your divorce lawyer to also represent your spouse? Probably not. Right? Same principle. Different interests require different representation.

What it costs you

Here’s the part that confuses a lot of people. In Ontario, buyer agents have traditionally been compensated through a commission split — the seller agrees to pay a total commission, and a portion goes to the buyer’s agent. Under recent regulatory changes and TRESA requirements, there’s more transparency now about how agents are compensated, and buyers should have a clear written agreement with their agent about representation and compensation before touring properties.

What I’d encourage any buyer to do is have that conversation upfront. Ask your agent how they’re paid, what services they provide, and what your obligations are. A good agent will welcome that conversation because they have nothing to hide. And when you understand the value — market intelligence, negotiation expertise, legal protection, and someone whose job it is to fight for your interests — the math makes sense.

I’m obviously biased. This is what I do for a living. But I’ve seen too many buyers try to go it alone or rely on the listing agent to “help them out,” and it almost always costs them more than proper representation would have. The stakes in the GTA — where the average home price is north of a million dollars — are just too high to wing it.
