Withdrawing an Offer to Settle in Ontario: Can You Take It Back?

You've made a settlement offer in your Ontario lawsuit, and now you've had second thoughts — maybe new information has come to light, or you simply offered more than you should have. Can you still withdraw an offer to settle before the other side accepts it? In most situations, yes, but the details matter, and timing is everything.

This guide walks through the basic contract principles behind revoking an offer, when an offer becomes locked in, and how to withdraw one properly if you need to.

An Offer to Settle Is Still an Offer

At its core, a settlement offer in litigation follows the same basic principles as any contract offer: it's a proposal that becomes a binding agreement only once it's accepted. Until that acceptance happens, the general rule is that the person who made the offer can take it back.

This matters because litigants sometimes assume a formal, written settlement offer is somehow more binding, or more permanent, than an everyday offer, but the underlying contract law principles are largely the same.

When You Generally Can Withdraw

As a general rule, you can withdraw an offer to settle any time before the other side communicates their acceptance back to you. Once you've clearly and effectively communicated the withdrawal, and the other side has actually received it, the offer is off the table, and they can no longer accept it.

When You Generally Cannot Withdraw

An offer stops being freely revocable in a few common situations:

• The other side has already accepted it — at that point, you have a binding settlement agreement, not just an offer
• You've given the other side something of value in exchange for a promise to keep the offer open for a set period — this creates a separate, enforceable promise not to revoke
• The offer itself states it will remain open for a defined period, and revoking early could create its own legal complications, particularly if the other side relied on that promise to their detriment

If any of these apply to your situation, get legal advice before assuming you can simply pull the offer back.

How to Withdraw an Offer Properly

1. Put the withdrawal in writing — don't rely on a verbal statement alone
2. Clearly state that the specific prior offer is withdrawn, referencing its date or key terms
3. Send it in a way you can prove was received, through your lawyer if you have one
4. Confirm the other side hasn't already sent an acceptance before your withdrawal reaches them — timing genuinely matters
5. Keep a copy of the withdrawal and any proof of delivery

Why Settlement Offers Can Be More Complicated Than They Look

Basic contract law explains most of what you need to know about withdrawing an offer, but litigation adds a few wrinkles worth flagging. A formal offer made in the course of a lawsuit can carry cost consequences later in the case, even if it's withdrawn and never accepted — the fact that an offer existed, and its terms, can sometimes still matter when a court considers the parties' overall conduct. That's a separate issue from whether the offer itself was validly withdrawn, but it's a reminder that offers made during litigation aren't purely private, informal gestures.

What Happens If You Withdraw Too Late

If the other side accepted your offer before your withdrawal was communicated, you may already have a binding settlement, even if you regret the terms. Trying to walk away from an accepted settlement offer is a very different, and much harder, problem than withdrawing an offer that hasn't yet been accepted.
