John Chapman's practice is in corporate and commercial litigation, and includes contract disputes, real estate litigation, shareholder remedies, fiduciary obligations, insolvency and class actions.
John has appeared before all levels of trial and appellate courts and before domestic and international arbitral tribunals. A significant percentage of his practice is in the Ontario Commercial Court. He has also represented members of the National Hockey League in salary arbitrations with their players.
He has successfully acted as lead counsel on multi-million dollar disputes, which have included: the supply of defective equipment in an Australian zinc refinery; cost overruns and delays in a hazardous waste decontamination project; litigation surrounding the closure of major anchor supermarket tenants in retail malls; the restructuring of a major beverage manufacturer plagued by highly acrimonious shareholder relations; delay and deficiency claims pertaining to gas co-generation facilities; failed automotive joint ventures; the enforcement of security by major Canadian financial institutions; and mass investor frauds.
Many of his cases involve the need to organize complex financial, technical or scientific facts so that they can be properly understood by the court.
Given his experience with such diverse and complex litigation matters, he is comfortable working with clients to create and monitor litigation budgets and in using technology to minimize litigation costs where possible.
John has written many articles on topics encountered in complex commercial litigation published in leading Canadian law journals.
