Biographical Information


Jack Zwicker has extensive experience in negotiation acquired during the course of 41 years as a lawyer in the fields of corporate/commercial and property law.

His combined skills in helping clients negotiate workable agreements, and in litigating in the same areas of the law, have enabled him to develop an approach to mediation which emphasizes the need for realism and makes a place for creativity. This two-pronged approach allows clients in conflict to work out solutions which the law alone may not make available to litigants.

Jack has worked with both private and public sector clients as a trainer and as a workplace process designer. He has conducted workshops for the Social Services Department of the Regional Municipality of York Region and is presently involved in training workshops with the Real Estate Council of Ontario, the licensing body for Ontario’s real estate agents.

Jack has also acted as a private arbitrator working with parties before the courts who have decided to arbitrate rather than litigate and was appointed in 2013 as a Deputy Judge of the Ontario Small Claims Court where he mediates with parties in an attempt to settle their claims, and to act as a trial judge where settlement is impossible.

Jack also regularly lectures and contributes to several publications. His article, “Mediation is the Message” appeared in the December, 2003 issue of CA magazine, which services Canada’s chartered accountants.
