Fabricating or exaggerating a competing offer violates all four.

RECO investigative outcomes (public records): registrants have been suspended for 30 days to 2 years, fined $10,000–$50,000 individually, and the brokerage of record also bears responsibility for supervision failures. Where buyers later prove they overpaid, civil damages stack on top.

The Multiple Representation rules (post-2024) further require written disclosure of all conflicts to all parties — making it harder to hide invented offer details.

Practical options sellers now have:
1) Standard sealed multiple-offer presentation — traditional blind bidding, agents present sequentially.
2) Open disclosure — current top offer’s price/terms are shared with other bidders, who get one chance to revise.
3) Partial disclosure — share the top price but not deposit, conditions, or closing date.

You must instruct your agent in writing which method you’re using. Each has trade-offs — open disclosure can attract more bids in slower markets but may scare off serious buyers in hot markets.

Detection signals:
• No registration on TRREB Authentisign or similar: if buyer agent asks “who registered the competing offer and what brokerage?” and the listing agent gets vague, that’s a red flag.
• Inconsistent talk-track: the listing agent says “the other offer is at $1.18M with no conditions” early, then later changes to “actually $1.16M with deposit due in 24 hours” — buyers walk away.
• Pricing patterns: in a balanced market, multiple offers above asking with no real bidding war signs (DOM > 25 days, few showings) trigger suspicion.
• Direct request: buyer agent may simply ask “can we see proof — a redacted offer signed page or registration timestamp?” TRESA now allows this disclosure if seller instructs.

Once detected (or even suspected), buyer walks. You’ve lost the deal.

Common civil claims:
• Fraudulent misrepresentation — buyer overpaid based on false information
• Negligent misrepresentation — seller and agent had duty to disclose accurately
• Rescission — buyer seeks to unwind the deal entirely

Damages typically include: overpayment amount, legal fees, inspection and appraisal costs, sometimes punitive damages for intentional fraud.

Ontario case patterns: sellers have been ordered to pay $40,000–$200,000+ where phantom-offer misrepresentation was proven. Agents lose licences. Brokerages face supervision sanctions. The chain of liability is real and tracked.

2) Set the offer presentation date and offer-night format. Single dedicated night, multiple registered offers, sealed or open per your instruction. Drives urgency.

3) Pre-list marketing burst. 5–7 days of intensive social, agent tour, broker open, public open — followed by offer date.

4) Escalation clauses. Buyers offer with auto-escalation up to a cap. Generates higher final prices without bidding theater.

5) Bully offer policy. Decide upfront whether you’ll accept pre-emptive offers (“bully offers”). Listing should clearly state.

Sealed format (traditional):
• “We have multiple offers — would you like to improve your offer before we review them?”
• Each buyer submits one best offer; you review all in sequence; counter, accept, or reject.

Open format (post-2024):
• “The current leading offer is at $1.18M with deposit of $50K and a single financing condition.”
• Each buyer gets one chance to revise.

Don’t: exaggerate price (“the top is at $1.20M” when it’s $1.16M), invent terms, or pretend offers exist that don’t.
Do: be precise. “We have 3 registered offers and will be reviewing tonight” is enough. The truth has its own pressure.
