Born in 1947, Leo Adler has been practicing law since 1973. After earning his law degree, he articled for the firm of Robertson, Lane, Frankish, Perrett, and Estey before being called to the Bar of Ontario in 1975. In 1972-73, Mr. Adler was named Special Project Directory for the Ministry of the Attorney General of Ontario and worked on the reorganization of the Provincial Court’s Family Division. He worked with one other firm, Goodman and Carr, before opening his own law office, now known as Adler Bytensky Prutschi Shikhman.

Leo Adler: A Career Devoted To Justice

Mr. Adler’s legal practice has focused almost exclusively on criminal defence, although he has also appeared before other types of boards, tribunals, and inquests. He has also served as counsel in matters concerning extradition, trials, and quasi-criminal proceedings throughout the Province of Ontario. His practice is based in Toronto, but he has argued cases throughout Canada, including in Quebec, Manitoba, New Brunswick, Alberta, and British Columbia, as well as before the Canadian Supreme Court.

He has handled cases involving virtually every type of crime, and has also represented individuals accused of criminal activity in Europe and the United States. He has extensive experience with cases involving DNA and other forensic evidence; this expertise has made him a highly sought-after consultant in these areas. Several of these cases have set important legal precedents in Canadian criminal law.

Mr. Adler shares his knowledge with the next generation of lawyers through his work as an adjunct professor at Osgoode Law School of York University, where he has taught Trial Advocacy for over 15 years. He is also involved with the school’s Intensive Criminal Law Program. He is a member of the Criminal Lawyers Association, the National Association of Criminal Defence Lawyers, the International Association of Defence Attorneys, and the Canadian Forensic Society.

For ten years, from 1999 to 2009, Mr. Adler was the Director of National Affairs for Friends of Simon Wiesenthal Center for Holocaust Studies. In this position, he was responsible for the NGO’s social action programs and public relations campaigns. He spoke and attended conferences and seminars around the world, providing media commentary on war crimes, the International Criminal Court, human rights, and legal issues involving the internet, as well as topics relating to national security and terrorism.

In February of 2005, Mr. Adler was one of 15 people appointed to the Cross Cultural Roundtable on National Security to review the new Anti-Terrorism Act and its impact on Canadian society. In 2006, he was invited by the Government of the Russian Federation to be a part of that year’s G8 NGO committee, where he was successful in persuading the NGOs to adopt a resolution condemning suicide bombing as a crime against humanity.

In addition to being a successful attorney, Leo Adler is married with two children and several grandchildren.
