Offer conditions that protect you: an Ontario buyer's checklist

Which conditions belong in an Ontario offer, how each one should be worded, and how each one ends: waived, fulfilled or expired.

Which conditions belong in an Ontario offer, how each one should be worded, and how each one ends: waived, fulfilled or expired.

⚖️ This is general information, not legal advice. It can't account for your specific situation. Use it to get oriented, then confirm the details with a licensed Ontario lawyer.

An Ontario offer becomes a binding agreement of purchase and sale the moment the seller accepts it before the irrevocable time. There is no cooling-off period for a resale home, so anything you need to check afterwards has to be written in as a condition before you sign. This checklist lists the conditions we see protect buyers most often, explains what each one is for, and shows the wording points that decide whether a condition actually lets you walk away with your deposit. Use it with your agent when the draft offer is being prepared, and send us the draft before it goes in.


How a condition works

A condition is a term of the agreement that lets one party end the deal if something does not happen by a deadline. In the common Ontario forms, a buyer's condition says that unless the buyer gives written notice by the deadline that the condition is fulfilled or waived, the agreement is at an end and the deposit is returned in full without deduction. Time is of the essence: a notice delivered an hour late is late.

Conditions can be drafted for the buyer's benefit alone, which means only the buyer can waive them. They can also be drafted objectively (the inspection reveals no defect costing more than a stated sum) or subjectively (an inspection satisfactory to the buyer in the buyer's sole and absolute discretion). Subjective wording gives you the most room; sellers in competitive markets push back on it.

Wording that matters

How each condition ends

Three things can happen at the deadline. You deliver a notice of fulfilment (the condition was met), you deliver a waiver (you give the condition up regardless), or you do nothing and the agreement ends. Some forms treat silence as termination; a few treat silence as waiver, which is dangerous. Read the form and diarise every date.

Once every condition is waived or fulfilled the agreement is firm. If you then cannot close, the seller can keep the deposit and sue for any loss on resale. That is why a financing condition should not be waived on the strength of a pre-approval alone.


How Treadstone Law can help
