Mediation is an important step in any legal case. In fact, mediation is so important, that in Toronto, Ottawa and Windsor, mediation is actually required BEFORE a matter can be set down for trial. The Financial Services Commission of Ontario (FSCO) requires that all accident benefit disputes get mediated BEFORE they can proceed to Arbitration or to litigation. if you fail to mediate, then you can’t proceed.
