“Howard’s vast experience in competition law, adjudication and dispute resolution and corporate governance, combined with his strong knowledge of Canadian and international securities regulation, will add a unique perspective to the services and counsel we offer to our clients,” says Dale Lastman, chairman of Goodmans, in a statement.

Prior to heading the OSC, Wetston also served as vice chairman at the regulator. He was also chairman and CEO of the Ontario Energy Board (OEB), and a federal judge. Wetston was replaced at the OSC by Maureen Jensen, who was appointed to a two-year term earlier this year.
