He has also been retained to litigate disputes elsewhere in, and outside of, Canada. Doug is regularly retained by exploration and production companies and other businesses in the energy industry, both private and public, due to his understanding of his clients’ businesses and his significant oil and gas litigation experience.

Doug obtained his Bachelor of Arts degree in philosophy after attending the University of Lethbridge and University of Calgary and obtained his law degree from Dalhousie University. Doug has been a member of the firm’s litigation group since completing his articles with McCarthy Tétrault.
