What is TRESA — advertising changes

TRESA — the Trust in Real Estate Services Act — is the Ontario statute governing brokerages and agents, the renamed and modernized successor to REBBA, with its biggest phase of changes in force since December 1, 2023. For advertising, the practical delta was narrower than the headlines suggested: the descriptor rules were updated — including regulated use of “real estate agent” — self-promotion boundaries were sharpened under a strengthened ethics regime, and RECO refreshed its guidance. What follows is the marketing-facing slice: what actually changed, what didn’t, and what to check on a live website. General information, not legal advice.
What TRESA is, in one paragraph
The statute itself is bigger than marketing. TRESA amended and renamed REBBA rather than replacing it outright, and its 2023 phase reshaped representation (client or self-represented party, with the old “customer” category abolished), introduced designated representation, made seller-directed open offer processes legal, and moved the code of ethics into regulation with a stronger enforcement toolkit for RECO. The full statute story lives in the TRESA glossary entry; this page stays on the advertising slice, because that’s the part that shows up on your website.
The headline change: descriptors
The most visible marketing change was to what registrants may call themselves. Ontario advertising has always required your name as registered, accompanied by a permitted descriptor for your registration class — and TRESA’s 2023 package updated that descriptor menu, most famously bringing “real estate agent” into regulated use after years of it being the term consumers used and registrants avoided. The compliance mechanics didn’t loosen: the descriptor must be a currently permitted one for your class, used accurately. The practical bite is stale strings — a title hard-coded into a website header, email signature, or template footer years ago doesn’t update itself when the menu changes, which is an argument for descriptors living in one editable place on your site rather than being typed into forty page footers.
What didn’t change
Just as important for a website audit is the list that carried straight through. Your registered name in advertising: unchanged. The brokerage identified clearly and prominently — the number-one complaint generator, covered in brokerage name on real estate websites — unchanged. Nothing false, misleading, or deceptive: unchanged. Consent before identifying parties to a transaction: unchanged. And the scope rule that these obligations apply to websites and social media identically: unchanged. TRESA re-founded the enforcement of these rules — the ethics code now sits in regulation — but the day-to-day advertising obligations under it are recognizably the same regime agents already knew.
What to actually check on your website
The TRESA-era audit is short. Descriptor strings: every place your title appears — header, about page, footer, bio, signature — carries a currently permitted descriptor, one consistent choice, no pre-2023 leftovers. Identity: registered name exact, brokerage prominent sitewide. Claims: awards, production numbers, and team-credit statements literally true in their current form. Consent: any identified past transaction backed by a consent file. That checklist, expanded and ordered by complaint frequency, is RECO’s advertising rules for websites — run it once after any rebrand and the TRESA transition holds no surprises for you.
Why the change list is dated
Descriptor rules are regulatory guidance, and guidance gets revised — the safe habit is to treat any specific descriptor claim, including this page’s, as current as of mid-2026 and to check RECO’s published guidance before printing signs or shipping a rebrand. The deeper lesson of the TRESA transition is architectural rather than legal: regulations change on their own schedule, so the websites that transitioned cheaply were the ones where identity, titles, and disclosures lived in one place. Build for the next amendment, not the last one.
Frequently asked questions
Can I finally call myself a real estate agent in Ontario?
Under TRESA's updated descriptor rules the phrase entered the regulated menu — a notable shift, since consumers always said 'agent' while the rules said otherwise. The condition is using a permitted descriptor for your registration class, correctly. Check RECO's current guidance for the exact strings before you reprint anything.
Did TRESA change the brokerage-name requirement?
No — that obligation carried through intact. Your registered name with a correct descriptor, and your brokerage clearly and prominently identified, remain the backbone of Ontario advertising compliance under TRESA exactly as before the 2023 changes.
Do the advertising rules under TRESA apply to my social media?
Yes, identically. Anything used to trade in real estate — website, Instagram, signs, flyers — is advertising under RECO's rules, so descriptor and identification requirements follow you across every surface. The profile bio is the practical place to carry them on platforms where individual posts can't.
