The New Rules of Engagement: TRESA, SRP, and the DIY Seller.

Navigating the End of the "Customer" Era and the Advice Ban for Self-Represented Parties.

May 9, 2026 4 min read

If you are planning to sell your home in Ottawa without a listing agent, the legal landscape shifted significantly on December 1, 2023. The introduction of the Trust in Real Estate Services Act (TRESA) effectively ended the “Customer” era.

If you are selling your own home (FSBO), you are now classified in the eyes of the law - and every agent you encounter - as a Self-Represented Party (SRP). This isn’t just a change in vocabulary; it’s a change in the mechanics of how information moves between you and the buyer’s side.

The Death of “Customer Service”

Under the old rules, an agent could treat you as a “customer” and provide basic administrative help. Under TRESA, that middle ground has been deleted.

The Binary Choice: You are either a Client (protected by fiduciary duty) or an SRP (operating entirely on your own).

The Advice Ban: If a buyer’s agent brings an offer to your door, they are legally prohibited from giving you any advice, opinions, or “coaching.” If you ask, “Is this a good price for my neighborhood?” they cannot answer. Their sole duty is to extract the best possible terms for their client, not to help you navigate the trade.


"The Information Gap: Any data you share with a buyer’s agent—like your motivation for moving or your 'bottom line' price—is not confidential."


They have a legal obligation to pass that intelligence directly to their buyer to use against you in negotiations.

FSBO vs. SRP: The Execution Friction

While “For Sale By Owner” may be your business model, “Self-Represented Party” is your legal status. Operating in this space requires you to handle the functional load that used to be shared.

The RECO Guide: Before any agent can even discuss an offer with you, they must provide you with the RECO Information Guide. You’ll be asked to sign an acknowledgment. This doesn’t make you a client; it’s a legal receipt confirming you understand you’re on your own.

Disclosure Risks: TRESA has sharpened the focus on “Material Facts.” As an SRP, you are personally liable for disclosing anything that could impact a buyer’s decision. If there is a failure in the building envelope (like a historical water leak) and you don’t disclose it correctly on the OREA forms, the legal “delta” falls entirely on your shoulders.

Open Bidding Mechanics: If you get multiple offers, the new rules allow for “Open Bidding,” where offer details can be shared. As a DIY seller, managing this transparency without a lead operator can lead to a basis swap error - where you accidentally leave money on the table by miscalculating the market’s actual ceiling.

The Trade-Offs

Selling on your own is a choice of capacity. You are trading your time and legal risk for the commission savings.

The “Commission Mirage”: Many FSBO sellers expect to save 5%. In reality, most buyers in Ottawa are still represented by agents. To get those buyers through your door, you usually still have to pay the buyer-side commission (typically 2-2.5%). Your actual “save” is the listing side, but you’ve inherited 100% of the technical workload and liability.

Vetting Failure: Without an agent, you are the one filtering the “looky-loos” from the “vetted buyers.” If you aren’t verifying proof of funds or pre-approvals before opening your front door, you’re wasting your most valuable asset: your time.

The Bottom Line

TRESA was designed to protect consumers by making it clear who is - and isn’t - looking out for them. If you choose to be an SRP, you are choosing to be the sole mechanic under the hood of your transaction.

I maintain a low-volume, relational practice where I handle the technical and legal “guts” so my clients don’t have to. I only take on a limited number of files to ensure I have the capacity to manage the high-signal data and negotiation logic required in this new regulatory environment. If you want to discuss whether representing yourself or hiring a dedicated operator is the right fit for your current life-state, we can look at the math together.
