Caveat emptor sounds like it settles the question before you even start: buyer beware, seller says nothing, done. It does not settle much of anything on its own. The doctrine has three named exceptions that swallow a large share of what a seller actually knows, and RECO’s own bulletins put an affirmative obligation on you, the agent, to go find out what your seller client knows — not just wait to be told.
Key takeaways
Start with what the doctrine actually says, not the shorthand version of it. Treadstonelaw’s summary: “At its core, caveat emptor means a seller has no general legal duty to volunteer everything they know about a property.” (Caveat emptor: buyer beware in Ontario real estate) The burden sits with the buyer to inspect. But three exceptions do most of the practical work in a listing intake conversation. First, a known dangerous or uninhabitable latent defect: “a defect that isn’t visible on a reasonable inspection, that the seller actually knew about, and that renders the property unsafe or uninhabitable falls outside the general rule.” Second, active concealment — the article’s own example is deliberately specific: “a seller who takes steps to hide a defect — painting over evidence of a leak right before showings, for example — moves from passive non-disclosure into active concealment, which the law treats far more seriously.” Third, a false statement: “if a seller answers a direct question dishonestly, or makes a false statement… that statement can support a misrepresentation claim regardless of whether silence alone would have been acceptable.”
The line between what must be disclosed and what does not turns on a specific definition, not a general impression of severity. Treadstonelaw’s glossary entry: “a latent defect is a hidden problem with a property that is not discoverable by a reasonable inspection” and “a material latent defect is one that makes the property dangerous to live in, unfit for habitation, or otherwise significantly impairs its use.” (What is a material latent defect in Ontario?) RECO’s Bulletin 7.4 puts the same distinction in its own words, and adds a detail worth building into every listing conversation: “a patent defect is one that can be detected by a potential home buyer or their home inspector by reasonable observation and inquiry,” while a latent defect “would make a property unfit for habitation, dangerous, or potentially dangerous, and is generally not apparent to someone exercising reasonable care.” Critically, the bulletin states the source of this rule directly: “the seller’s obligation to disclose and the facts or defects they must disclose are based on current case law, not TRESA.” (RECO Bulletin 7.4 — Facts a seller has a legal obligation to disclose) This is not a statutory checklist you can point to; it is a body of case law your seller-intake questions have to anticipate.
RECO Bulletin 7.3 does not leave “material fact” as an abstraction. It lists concrete examples: “the type of insulation and wiring (for example, knob and tube wiring)”; “the type of plumbing (for example, lead piping or galvanized plumbing)”; “the age, condition, and ownership status of any major home systems”; “a history of flooding, structural damage, or any previous dwelling fire”; “renovations and improvements made to a property and whether the required permits were obtained”; “property tax amount and if there are any special assessments or local improvement charges”; “zoning by-laws… impacting the legal use of the property”; and “whether a property had been used as a marijuana grow operation or for other illicit purposes.” (RECO Bulletin 7.3 — Material facts) The bulletin also names a category easy to skip in an intake form: “a new hospital or other neighbourhood improvement that may increase the value of the property that the agent is or should be aware of” — a material fact that runs in the seller’s favour, not against it, and still has to be captured.
Bulletin 7.3 does not stop at listing categories — it sets a process for the agent: “take reasonable steps to determine the material facts; promptly disclose the material facts to the client; advise the client to consider if the material facts might affect their decision; and make best efforts to obtain an acknowledgement indicating that the disclosure and advice were received.” It adds a specific warning about the first step: the “‘reasonable steps’ required for determining those material facts is not met by simply accepting the seller’s verbal representations” — some research, verification, or supporting documentation is expected. Bulletin 7.4 restates the disclosure duty in mandatory terms for the seller’s own agent: where a fact is known and the seller is legally obligated to disclose it, “the seller’s agent must disclose the fact(s) to every buyer that expresses an interest in the property” and must “use best efforts to obtain an acknowledgement from each buyer.” (RECO Bulletin 7.4)
Some questions a buyer cares about are not defect questions at all. RECO Bulletin 7.5 is explicit that “the legislation does not define ‘stigma’,” and lists examples including “a death occurred at the property” and the property “was previously owned by a notorious individual.” (RECO Bulletin 7.5 — Stigmas) Treadstonelaw’s own answer on the point is direct: sellers “generally are not required to volunteer this kind of history on their own initiative,” because a death “is typically treated as what’s sometimes called a ‘stigmatized property’ issue rather than a latent physical defect.” (Death in home disclosure obligation, Ontario) The exception is identical to the general rule above: if the seller is asked directly and lies, that lie is actionable on its own. The practical advice is the same in both sources — if a buyer cares, put the question in writing and get the answer in writing, because that is the only reliable route to a real answer either way.
A worked example
A seller mentions offhand that the basement “had some water once, years ago, all fixed now.” Treadstonelaw’s flooding-specific guidance draws exactly this line: “fully repaired, with the underlying cause addressed” sits on one side, and “patched, painted over, or the cause never identified” sits on the other — and “concealing evidence of past water damage (for example, through fresh paint specifically applied to hide staining) can amount to active concealment.” (Disclosing basement flooding when selling in Ontario) “All fixed now” is not a documented answer. The follow-up questions — what caused it, what was done about it, is there an invoice or a contractor’s name — and the written record of the seller’s answers are what turns “direct questions call for honest answers” from a legal principle into something you can actually produce if the buyer asks later.

Treadstonelaw’s own material-latent-defect guidance frames it as something provided in some transactions, not every one — a false statement matters “including in a Seller Property Information Statement, where one is provided.” What is not optional is that any answers actually given, on that form or verbally, have to be truthful.
Caveat emptor’s exceptions turn on what the seller actually knew, not on what a diligent seller should have known — the doctrine does not create a duty to investigate their own property looking for problems. Bulletin 7.4 does add a wrinkle: a seller who was wilfully blind to an obvious problem can still face exposure, which is different from genuinely not knowing.
A refusal to answer is itself information — document that the question was asked and declined, in writing, rather than letting the file go silent on it. It will not manufacture a disclosure duty that does not otherwise exist, but it protects you and your client if the same question resurfaces after closing.
A short call can help you turn RECO’s material-facts categories into a written intake process for your listings.
