Coulston wanted to be a lawyer for as long as he can remember. His godfather, who was a close friend of his father, was a lawyer and responsible for introducing Coulston to the idea of a career in law. Coulston was delighted to also have his father as a major supporter of his ambitions.

Coulston’s attraction to the law was rooted in his commitment to service. “It was an opportunity to get out and provide services to people.” Coulston wanted a career that provided him access to a wide variety of people and challenges because he knew that was the key to keeping his work interesting. He has not been disappointed. “Every case is different and I thrive on working with clients, being in litigation, in the courtroom, and in front of tribunals.”

His first job with a law firm was to fill an opening in the Employment Law department. It was a brand new area of law and it caught Coulston’s imagination and interest. “There is nothing like learning something for the first time. You tend, if you are concerned about it enough, to go overboard.” Coulston’s long hours of research and preparation in that first job laid the foundation for the skills and knowledge he has continued to acquire since that time.

A number of years ago Coulston was responsible for a Labour Law arbitration that was made more challenging because, for the first time, Human Rights’ issues were involved. His successful work in this case set a legal precedent for those that followed.

Though his family takes up most of his “spare time,” Coulston’s community work takes him to the hockey rink where he coaches minor hockey. His love for the sport comes from his own playing days as a boy and in high school, when he played Tier 2 Junior A hockey in Toronto.
