The Honourable Mr. Justice Denis Power Q.C.
In 1963, Mr. Justice Power Q.C. joined Mr. Nelligan’s law office as an articling student, and in 1969, the Nelligan Power partnership was established.

In October 2000, Denis Power Q.C. was appointed a judge of the Ontario Superior Court of Justice. According to the rules established by the Law Society, when a “firm name” partner accepts an appointment to become a judge, the firm is required to change its name. Effective immediately, the firm’s name was changed to Nelligan O’Brien Payne LLP. Allan O’Brien and Janice Payne are long-time partners of the firm and continue to practise at the firm today. Certified by the Law Society of Upper Canada as a specialist in civil litigation, Mr. Justice Power Q.C. is a former Director and Officer of the Advocates’ Society.

He then attended law school at the University of Ottawa and graduated in 1963 with an LL.B.
After completion of his articles and the Bar Admission Course, Denis Power Q.C. was called, with honours, to the Ontario Bar in the spring of 1965. He then began practising law with John P.

Over the course of his legal career, Denis has been involved in many areas of law. His specialities, however, are litigation, labour law, and education law.
As a result of Denis’ involvement with education issues, he also possesses a speciality in the area of education law including denominational education rights.

In addition, he also served for several years as a director and officer of the Ontario Advocates’ Society.
