When two sides in a dispute want the flexibility of mediation but also want certainty that the matter will actually end, med-arb offers a middle path. It combines two dispute resolution processes into one continuous proceeding: the parties try to settle through mediation first, and if that fails, the process moves directly into binding arbitration — without starting over from scratch.
For businesses and individuals who want to avoid the cost and public exposure of a courtroom trial, but still need a guaranteed resolution if talks break down, med-arb has become a common option in commercial contracts, partnership disputes, and construction disagreements.
This guide explains how the hybrid process actually works, who runs it, and when it makes sense to choose med-arb over separate mediation and arbitration proceedings.
What Is Med-Arb?
Med-arb is a single dispute resolution process with two distinct stages:
- Mediation stage — a neutral third party helps the parties negotiate a voluntary settlement.
- Arbitration stage — if mediation does not resolve every issue, the process shifts into arbitration, and the neutral (or a freshly appointed neutral) issues a binding decision.
Because the arbitration stage is governed by Ontario’s Arbitration Act, 1991, the resulting decision — the arbitration award — is generally enforceable much like a court judgment, with only limited grounds of appeal. That is the key advantage over mediation alone: mediation cannot force an outcome, but med-arb guarantees one.
How the Process Works
Most med-arb processes in Ontario follow a similar sequence, though the exact steps depend on what the parties agree to — often set out in a contract’s dispute resolution clause or a separate med-arb agreement signed once a dispute arises:
- The parties agree to med-arb — either because a contract requires it or because they choose it after a dispute starts.
- A neutral is selected — someone qualified to act as both mediator and arbitrator, or two separate people if the parties prefer.
- Mediation proceeds first — the neutral meets with both sides, explores settlement options, and tries to narrow or resolve the issues.
- Unresolved issues move to arbitration — anything mediation does not settle gets decided through a more formal arbitration hearing, with evidence and submissions.
- The arbitrator issues a binding award — this resolves the dispute and is enforceable in the same way a court judgment is.
One Neutral or Two?
A key design choice in any med-arb process is whether the same person acts as both mediator and arbitrator.
- Same neutral for both stages — efficient and often less expensive, since the arbitrator already understands the dispute from the mediation stage. The tradeoff is that the neutral has heard confidential settlement positions during mediation, which can raise concerns about impartiality once they switch to a decision-making role.
- Different neutrals for each stage — preserves a cleaner separation between the settlement discussion and the binding decision, at the cost of some efficiency, since the arbitrator starts fresh.
Many med-arb agreements address this directly, specifying in advance whether the same person continues into arbitration or a new arbitrator is brought in.
Med-Arb Compared to Separate Proceedings
| Med-Arb | Separate Mediation, Then Arbitration | Litigation | |
|---|---|---|---|
| Guaranteed final outcome | Yes, if mediation fails | Yes | Yes |
| Privacy | Private | Private | Generally open to the public |
| Continuity of neutral | Often the same person throughout | Usually a new arbitrator | Not applicable |
| Flexibility to settle first | Built in | Built in, as two separate steps | Limited — settlement is optional, not structured |
When Parties Choose Med-Arb
Med-arb tends to appeal to parties who:
- Want to preserve an ongoing business or family relationship and prefer a collaborative first attempt at resolution
- Need a guaranteed, enforceable outcome if settlement talks stall, rather than an open-ended negotiation
- Want to keep the dispute out of the public court record
- Are already committed to arbitration under a contract and want to try mediation first, without a separate process and separate cost
Frequently asked questions
Is med-arb legally binding in Ontario?
The arbitration portion is binding once the parties have agreed to it, and the resulting award is enforceable much like a court judgment, with only limited rights of appeal. A settlement reached during the mediation portion is binding as a contract once both sides sign it.
Can I refuse to continue to arbitration if mediation doesn’t work?
Generally no, if you have already agreed to a med-arb clause or agreement — the arbitration stage is typically a mandatory continuation of the process, not an optional next step you can decline once mediation ends without a deal.
Does the same person always act as mediator and arbitrator?
Not necessarily. Some med-arb agreements use the same neutral for both stages for efficiency, while others bring in a different, independent arbitrator to decide any issues mediation does not resolve. The agreement itself should specify which model applies.
Is med-arb cheaper than going to court?
It is often less expensive than a full trial, mainly because it avoids extended pre-trial procedure, but the exact cost depends on the complexity of the dispute and how much of it settles at the mediation stage versus needing a full arbitration hearing.
