What is a Rule 49 offer to settle and why does it matter in Ontario?

Under Ontario's Rules of Civil Procedure, Rule 49 allows either party in a Superior Court civil case to make a formal "offer to settle" at any time after a statement of claim is issued. The rule has powerful cost consequences designed to encourage early settlement.

If a plaintiff makes a Rule 49 offer and the defendant does not accept it, and the plaintiff then obtains a judgment at least as favourable as the offer, the plaintiff is entitled to "substantial indemnity" costs (a higher rate) from the date the offer was made. This is a significant financial penalty on the party who rejected a reasonable settlement.

Similarly, if a defendant makes an offer and the plaintiff refuses it, and the plaintiff's eventual judgment is no better than the defendant's offer, the plaintiff may be ordered to pay the defendant's substantial indemnity costs from the date of the offer. This means rejecting a reasonable offer to settle can end up costing you more than you recover.

Rule 49 offers are powerful tools in civil litigation. A well-timed offer puts pressure on the other side to seriously evaluate their risk. Offers must comply with the rule's formal requirements to trigger the cost consequences. In Small Claims Court, a similar mechanism exists under Rule 14 of the Small Claims Court Rules.
