About MZS Lawyers

MZS Lawyers is a two-lawyer civil litigation firm in Ottawa. Founding lawyers Richard Nishimura and Marc Binavince have worked together since 2008, representing clients across Ottawa and Eastern Ontario in estate and property disputes, personal injury and auto accident claims, adult guardianship applications, debt collection, and general civil litigation. Personal injury cases are handled on contingency, so clients pay fees only if a claim succeeds, and the firm offers free consultations by phone, videoconference, or in person.

Nishimura, the managing partner, is a Dalhousie Law School graduate who has appeared before the Ontario Court of Appeal, the Superior Court of Justice, and the Human Rights Tribunal, and earlier worked for the Senate of Canada and as a human rights advocate in Washington, D.C. Binavince holds a law degree from Yale Law School and an undergraduate degree from Amherst College, and studied for a time in the University of Ottawa's Common Law Section. Before MZS Lawyers, Binavince practiced law from 2000 to late 2006 alongside family member Emilio Binavince, and as a young man had the chance to see Emilio Binavince argue the Operation Dismantle case at the Supreme Court of Canada. The firm also runs a dedicated guardianship resource at ontarioguardianship.com.
