Yes. No rule in Ontario prohibits using a tool to draft listing copy. What does not change is that the result is advertising: RECO’s bulletins under TRESA require the brokerage to be clearly and prominently identified, statements to be factually correct, accurate and verifiable, and consent before you identify a property or a party. You are accountable for every word, whether you wrote it or approved it.
Key takeaways
The question comes up in every brokerage. Someone drafts a listing description in a chatbot, it reads well, and the room splits between “that is the future” and “that must be against the rules”. Neither is right. There is no prohibition, and there is also no softening of the requirements — which is the part that matters, because the requirements are stricter than most listing copy currently meets.
Start with scope, because people assume “advertising” means a printed ad. RECO’s bulletin on advertising requirements under the Trust in Real Estate Services Act, 2002 defines it as any notice, announcement or representation directed at the public, authorised by or made on behalf of a brokerage or agent, intended to promote the brokerage, agent, or their business, services or trades, in any medium — print, radio, television, electronic media, or publication on the internet including websites and social media. It adds that business cards, letterhead, email signatures or cover sheets containing promotional statements may be considered advertising.
A listing description is squarely inside that. So is the caption you post with it, the version on your own site, and the email you send to your database.
Brokerage identification. All advertising must include the name of the brokerage, clearly and prominently, in the name registered with RECO, with the descriptor “brokerage” or “real estate brokerage”. Where an agent is named, the name used must be the one registered — short forms and nicknames must not be used — with an appropriate permitted term, which RECO covers in a separate bulletin on permitted terms. A model drafting punchy copy will happily drop all of this.
Accuracy that survives scrutiny. RECO’s standard is that all statements be factually correct, accurate and verifiable, and it defines an inaccurate representation as one characterised by a lack of precision — “a statement that is true but vague or incomplete in situations where clarity is necessary”. That is precisely the register generative copy defaults to. “Steps from transit”, “newly renovated”, “sun-drenched” and “in the sought-after school district” are all statements someone can test.
Comparative and volume claims. If the copy makes a comparative claim, it must be truthful and supported by verifiable facts, with the basis of the claim included; statements about business volume or trading activity must explain how the volume was measured; and honours or awards need the source, date and, for a team award, a statement that it is a team achievement and the size of the team.
Consent. Advertisements must not include anything that could reasonably identify a party to a transaction unless that party consents, must not identify a specific property unless the owner consents, and must not include anything that could reasonably be used to determine the contents of an agreement, such as price, unless all parties consent.
It is the shortcut, not the technology. Someone takes a well-written description from another listing, pastes it into a tool and asks for a rewrite. RECO’s bulletin on advertising online is blunt about this: using someone else’s publication, imagery or other intellectual property requires consent; plagiarism and scraping are unethical; and using images, logos and verbatim property descriptions created by someone else requires the written consent of the owner. A paraphrase produced by a model is still derived from a work you had no right to use, and the resemblance is usually obvious.
The same bulletin is worth reading for the online-specific points that AI-assisted volume makes worse: whether a website features the whole brokerage, a team or a single agent, they are all brokerage websites and the brokerage is responsible for their compliance; profiles must be kept current; and photo and video content cannot remain online past the end date in the written consent.
CREA has published a position and a 19-question FAQ. Its own summary of the principles is that AI use must be guided by transparency, accuracy and accountability, and that the adoption of AI does not alleviate the professional responsibilities of REALTORS®, who remain fully accountable for the information, advice and services they provide. On listing descriptions specifically, the FAQ says a REALTOR® using AI to write or translate a description should ensure it is accurate, and that producing inaccurate, deceptive or misleading listing information risks a finding under the REALTOR® Code — Article 13 on advertising content and accuracy and Article 15 on advertising claims.
The FAQ also flags something quieter that matters for anyone building a content machine: authorship and ownership of AI-generated content are unsettled in Canada, and CREA notes that copyright jurisprudence suggests an author must be a natural person, so protection may apply where there is meaningful human creative contribution while purely AI-generated content may not qualify. If your listing copy is a business asset, that is worth a conversation with counsel.
CREA’s own list of Canadian regulator guidance on AI names one real estate regulator: BCFSA. Its Artificial Intelligence Guideline tells licensees that using AI does not exempt them from their legal and ethical obligations, that AI tools are designed to guess answers to questions they do not have complete information on, and that licensees remain accountable for the accuracy of any real estate advertising they publish. It states directly that licensees must not publish advertising they know or ought to know contains a false statement or misrepresentation, that this applies to pictures as well as text, and that where AI is used to write listing content such as property descriptions, the information must be verified before publication. It also advises communicating to clients and the public when AI tools are being used.
CREA notes that the guideline directly applies only to REALTORS® in British Columbia, but that it contains useful information others may wish to consider. Ontario agents should read it as the clearest published statement of an expectation their own advertising rules already imply.
Four rules for AI-assisted listing copy
Feed it verified facts only. Build a short data sheet from the source documents — measurements, inclusions and exclusions, taxes, fees, age, parking — and instruct the model to use nothing outside it.
Forbid inference. No distances, no school claims, no permitted-use statements, no “could easily be converted”. If it is not on the sheet, it does not appear in the copy.
Check the material facts separately. Accuracy in the ad is a different obligation from disclosure; RECO covers the latter in its bulletin on material facts.
Add the required elements last, from a template. Brokerage name, registered agent name, permitted term, disclaimers. Never leave them to the draft.
The following is illustrative — a composite of how the workflow is usually assembled, not a measured result.
A five-agent team standardises on a single intake form completed at the listing appointment: measurements with their source, inclusions and exclusions verbatim from the schedule, taxes and any fees from the documents, and three specifics the seller mentions that would not be obvious from photographs. That form — and only that form — is what the drafting tool receives. It returns three variants at different lengths in the team’s voice.
The agent edits for tone, deletes one sentence the model inferred about the basement being “ideal for a suite”, and runs a fixed checklist: brokerage named and prominent, registered names used, no claim without a source on the sheet, consents on file for the property and any people shown. The cycle is shorter than writing from scratch because the facts were gathered once, and the compliance position is better than it was before, because the checklist is now a step rather than a habit.
There is no Ontario rule requiring it for text. For altered images the picture is different — CREA advises that it is prudent to disclose that an image has been altered by AI, and BCFSA tells BC licensees to label photos or videos that have been altered or enhanced so as not to mislead a buyer. BCFSA also advises telling clients when AI tools are in use, for example an AI chatbot answering when you are unavailable.
Not without thinking it through. BCFSA’s guideline tells licensees to obtain informed consent before putting client information into an AI tool and to review the provider’s privacy disclosures, and warns that anonymisation can fail when data from different sources is matched. The federal privacy commissioner’s principles for responsible, trustworthy and privacy-protective generative AI cover the same ground for organisations subject to PIPEDA.
CREA says it is not aware of any statute or regulation obliging a brokerage to have one, but calls it prudent — to give staff and salespeople guidance and to mitigate privacy, confidentiality, copyright, hallucination and discrimination risk. Given that brokerages are responsible for advertising compliance across every agent’s website and social media, a written policy is cheap insurance.
The same requirements apply to every derived asset. See generating feature sheets from the listing data and AI ad copy and Competition Bureau rules.
