During a distinguished thirty-three career as leading counsel acting in many prominent cases across Canada, he was elected a Bencher of the Law Society of Ontario and later served in its highest elected position as Treasurer in 2003. He was appointed a judge of the Ontario Superior Court of Justice in 2005, and elevated to Associate Chief Justice in 2013.

In his judicial career, Frank heard and decided significant matters across the full range of the Court’s work and as part of the Divisional Court. In 2018, he was appointed Commissioner of the Town of Collingwood Judicial Inquiry, resulting in a major report released in 2020 concerning the use of public funds arising from the sale of a municipal public utility and containing a series of recommendations for legislative and administrative reforms. He was also appointed by the Province of Ontario to lead the Long-Term Care COVID-19 Commission in 2020, which released its final report in April, 2021.
