Do I need a lawyer to attend mediation in Ontario?

In Ontario, you are not legally required to have a lawyer attend mediation with you, but it is strongly advisable, especially in cases involving significant money or complex legal issues. Mediation is a negotiation process and any settlement you agree to at mediation is binding. If you settle without understanding the legal implications of what you are agreeing to, you may give up rights or accept less than your claim is worth.

A lawyer can help you prepare for mediation by assessing the realistic value of your claim, identifying your strongest arguments, and advising you on what a reasonable settlement range looks like given Ontario law and similar cases. During the session itself, your lawyer can advise you privately in the caucus, evaluate any offers the other side makes, and flag problematic terms before you agree to them.

If you cannot afford full legal representation, consider consulting a lawyer in advance to discuss strategy and possible settlement ranges, even if you attend the actual session alone. Some community legal clinics and legal aid offices can assist with preparation. In complex commercial or employment cases, attempting mediation without legal representation puts you at a significant disadvantage relative to a represented opposing party.
