Anonymised, illustrative composite. An AI tool wrote a clean-reading special condition for an APS — clean enough that nobody noticed it never said the one phrase that would have made its deadline enforceable.
At a glance
A buyer's agent used an AI drafting tool to help phrase a custom financing condition for an $875,000 Ontario purchase, carrying a $50,000 deposit. The buyer needed a few extra days past the standard window to confirm a rate hold, so the agent asked the tool to draft a clause extending the financing-condition removal date. The output read cleanly, used the right defined terms, and named a specific date and time. It went into the APS as written, without a lawyer's eyes on it first — the deal was moving fast and the clause looked finished.
What the AI-drafted clause never said was that the date was firm. Ordinary Ontario contract-drafting practice treats a deadline as aspirational unless the contract says otherwise: as one Ontario legal-explanation source puts it plainly, courts generally will not imply a “time is of the essence” requirement unless the contract says so expressly, and without that language “a delayed party can argue the timeline was merely aspirational.” The clause set a deadline; it never made the deadline bind.
The financing condition was due to be removed by 5:00 p.m. on a Thursday. The buyer's lender confirmation came through at 12:40 p.m. the following day — roughly 20 hours late, after a documentation delay on the lender's side that had nothing to do with the buyer's diligence. The seller, mid-negotiation on a better backup offer, wanted the deal declared dead on the missed deadline and the $50,000 deposit released back to the buyer with no further obligation. The buyer wanted to close as planned, 20 hours late.
Both lawyers landed on the same reading independently: because the clause never stated that time was of the essence, the 5:00 p.m. Thursday cutoff was arguable as a target, not an automatic trigger that killed the condition the moment it passed. That reading didn't hand the buyer a guaranteed win — it meant the seller's “the deal is dead” position rested on a clause that a court could plausibly read either way, which is a weak place to litigate from on a $50,000 deposit. Competence over the drafting itself — not just the negotiation that followed — is squarely inside RECO Bulletin 1.1's competence principle: where a registrant cannot competently handle a task, the rule is to bring in someone who can, before the document is signed, not after a deadline is missed. The financing condition itself was a standard one; only the missing deadline language was the AI tool's own gap.
Both lawyers agreed the cleanest fix was a same-day mutual amendment: a new, explicit financing condition with a firm removal date 48 hours out, expressly stating time was of the essence this time, signed by both parties before end of day. The seller kept the deal instead of a fight over an ambiguous clause with a backup offer that wasn't guaranteed to be better; the buyer kept the $875,000 purchase and the financing they'd already secured. Total cost of the fix: about $650 in legal fees to draft and execute the amendment — split between the two sides' own lawyers, not a shared cost, but a small number next to what a contested $50,000 deposit dispute would have run.
Had either side pushed the ambiguous clause to a dispute instead of a same-day fix, the realistic outcome wasn't a quick answer — it was weeks of lawyer time arguing over whether a 20-hour-late confirmation killed a firm deal, with the $50,000 deposit frozen in trust the entire time and both a frustrated buyer and a seller who couldn't safely accept the backup offer until the first deal was formally dead. A $650 amendment closed in an afternoon what a contested deposit claim would have taken months and several thousand dollars in legal fees on each side to resolve, with no guaranteed outcome for either party at the end of it. The same failure mode, an AI output that reads as finished but is quietly missing a load-bearing piece, shows up again in an AI translation that changed the meaning.
The tell was in the clause's own confidence: it read like a finished legal document, complete with a specific date and time, and that polish was exactly why nobody flagged it before signing. A clause that sets a deadline but never says what happens if the deadline is missed is unfinished, no matter how clean its prose reads — and an AI tool that produces fluent language has no way of knowing that Ontario courts specifically will not infer the one phrase this clause was missing.
A 30-minute call is enough to tell you whether AI pays for itself here.
