Ontario’s Mandatory Mediation Program (MMP) offers an alternate dispute resolution process within the traditional civil justice system. The MMP applies in Toronto, Ottawa and Essex County (Windsor) to:

People involved in cases using mandatory mediation in these three jurisdictions can hire private-sector mediators from local mediation rosters. People can also hire a non-roster mediator to mediate their case. If parties cannot agree on the selection of a mediator, the local mediation coordinator will appoint a mediator from the roster. 

Local mediation committees

Local Mediation Committees established in Toronto, Ottawa and Windsor supervise a system of mandatory referral to mediation in their respective communities. The responsibilities of local mediation committees, as described in rule 24.1, include:

  • creating and maintaining a current list of mediators that meet the Ministry of the Attorney General’s guidelines
  • monitoring the performance of mediators on the roster
  • receiving and responding to complaints about mediators on the roster

Committees will ensure that rosters meet the particular needs of their communities and have mediators who can work in both official languages.
