What Happens If Mediation Fails in Ontario?

Mediation does not always end in a settlement. Sometimes the two sides are too far apart on the numbers, one party isn’t negotiating in good faith, or the dispute involves a question neither side is willing to compromise on. If a mediation session ends without an agreement, it can feel like time and money were wasted — but a failed mediation is rarely a dead end.

Understanding what happens if mediation fails in Ontario, and what your realistic next options are, helps you decide how to move forward without losing momentum.

Mediation "Failing" Doesn’t Always Mean Total Failure

Before assuming nothing was accomplished, it’s worth recognizing that partial progress at mediation is common and useful:

• Some issues may have been resolved even if others weren’t
• Each side typically learns more about the other’s position and evidence
• Settlement numbers discussed, even informally, often narrow the eventual gap
• The parties usually remain free to keep negotiating informally afterward, even without a mediator in the room

A mediation that ends without a signed agreement can still meaningfully move a dispute closer to resolution.

Your Options After an Unsuccessful Mediation

1. Continue Negotiating Directly

Nothing stops the parties, or their lawyers, from continuing settlement talks after a mediation session ends. Many disputes settle in the days or weeks following mediation, once each side has had time to reflect on what was discussed.

2. Return to Litigation, If a Court Action Is Already Started

If your dispute is already in the Superior Court of Justice and mediation was court-ordered or scheduled under Rule 24.1, an unsuccessful mediation simply means the litigation continues along its normal track — toward examinations for discovery, pre-trial steps, and eventually trial, unless the parties settle first.

3. Move to Arbitration, If Your Agreement Provides for It

If your contract includes a med-arb clause, or the parties otherwise agree, an unresolved dispute after mediation can move into binding arbitration, governed by Ontario’s Arbitration Act, 1991. This produces a final, enforceable decision without a full court trial.

4. Try Mediation Again, Later or With a Different Mediator

Sometimes a second mediation session — after more information has been exchanged, or with a different mediator whose style fits the dispute better — succeeds where the first attempt didn’t. This is especially common in complex, multi-party, or high-emotion disputes.

5. Start, or Continue, a Court Action

If no lawsuit has been filed yet and mediation was a voluntary, pre-litigation attempt to resolve the dispute, the natural next step is typically to start a claim in the appropriate court — Small Claims Court, Simplified Procedure, or the ordinary Superior Court process, depending on the amount and complexity involved.

Does a Failed Mediation Affect the Limitation Clock?

Attempting mediation does not automatically pause the limitation period that applies to your claim. If a lawsuit hasn’t been started yet, don’t let settlement talks or a scheduled mediation session distract from tracking your deadline to sue. Ontario’s basic limitation period, and any shorter, claim-specific period that might apply, keeps running in the background unless the parties have specifically agreed in writing to suspend it.

What Was Said at Mediation Generally Stays Confidential

One of mediation’s practical advantages, even when it fails, is that settlement discussions are generally treated as confidential and cannot later be used against you in court. This encourages both sides to negotiate candidly, without worrying that a settlement offer will be read back to a judge as an admission.
