  • An offer to settle is a formal proposal, made in the course of a lawsuit, to resolve the claim on specific terms — usually a dollar amount, sometimes with other conditions attached.
  • Ontario civil procedure generally keeps formal offers to settle confidential from the judge until after the case has been decided on its merits.
  • Once the judge has ruled on liability and, where relevant, damages, the confidentiality generally lifts for one specific purpose: deciding costs.

If you've ever wondered why a judge deciding your Ontario lawsuit doesn't know what settlement offers were exchanged before trial, there's a deliberate reason for that. A formal offer to settle is generally kept confidential from the judge deciding the merits of the case, and is only revealed afterward — for a very specific purpose.

Understanding why this confidentiality exists, and what happens once it lifts, changes how many litigants think about making, or rejecting, a settlement offer.

What an Offer to Settle Is

An offer to settle is a formal proposal, made in the course of a lawsuit, to resolve the claim on specific terms — usually a dollar amount, sometimes with other conditions attached. Either side can make one, at various points in the litigation, without admitting anything about the merits of their position.

Why the Judge Doesn't See It Before Deciding the Case

Ontario civil procedure generally keeps formal offers to settle confidential from the judge until after the case has been decided on its merits. The reasoning is straightforward: a judge is supposed to decide who is right, and how much, if anything, is owed based on the evidence and the law — not based on what one side was privately willing to accept to avoid the risk and expense of trial.

If a judge knew, for example, that a defendant had offered a substantial amount to settle, that knowledge could unconsciously, or consciously, colour how the judge views the merits, even though an offer to settle reflects risk tolerance and litigation strategy as much as it reflects the actual strength of a claim.

What Happens After Judgment

Once the judge has ruled on liability and, where relevant, damages, the confidentiality generally lifts for one specific purpose: deciding costs. At that point, the court can consider whether either side made a formal offer earlier in the case, and whether the eventual result was more or less favourable than that offer would have provided. This can meaningfully affect who pays costs, and how much, encouraging both sides to make, and seriously consider, reasonable offers throughout the case rather than only at the courthouse steps.

Because the specific rules and consequences around offers to settle are technical and case-specific, and can carry real financial weight, get advice from a lawyer before making — or rejecting — a formal offer.

Practical Considerations When Making an Offer

Because a formal offer to settle can have real cost consequences later, even though the judge won't see it until then, it pays to treat the process seriously:

Because how these offers interact with the eventual costs award depends heavily on the specific numbers, timing, and procedural history of a case, working through the details with a lawyer before sending, or responding to, a formal offer is worth the time.

Why This Confidentiality Shapes Litigation Strategy

Because an offer only matters for costs, and only after the fact, parties are freed up to negotiate seriously without worrying that a generous offer will be read by the judge as an admission of weakness. This is part of what makes structured settlement offers a genuinely useful tool throughout an Ontario lawsuit, not just a courtesy exchanged in the hallway before trial.

Frequently asked questions

Can I tell the judge about a settlement offer during the trial?

Generally, no. Formal offers to settle are kept from the trial judge until the merits of the case have been decided, precisely to avoid influencing that decision.

Does making an offer to settle mean I'm admitting my case is weak?

No. Offers to settle reflect a party's assessment of risk, cost, and time, not necessarily the underlying strength of their legal position. Courts recognize this, which is part of why the offer is shielded from the judge until costs are considered.

What if the other side never responds to my offer?

An unanswered offer can still matter later, when costs are argued, depending on how the final result compares to what was offered. Track your offers and any responses carefully.

Is this the same as mediation confidentiality?

No, it's a related but separate concept. Mediation communications are generally protected under a different, broader confidentiality principle, while offers to settle have their own specific rule for when and how they become relevant, tied to costs.

Can an offer to settle be withdrawn once it's made?

Generally, yes, before it's accepted, though the specific rules and timing can matter. If you're considering pulling back an offer, get advice on the proper way to do it.
