The Honourable Marshall Rothstein, C.C., KC, is a partner based in our Vancouver office who provides valuable expertise and counsel firm-wide. One of Canada’s most esteemed jurists, he served as Justice of the Supreme Court of Canada from 2006 until his retirement in 2015, and he has over 50 years of judicial and legal experience.

Marshall’s work has shaped the Canadian business law landscape, having authored more than 100 judgments and arbitral decisions on domestic and cross-border cases of commercial significance and complexity. He brings a unique perspective to the firm, and his broad-ranging practice focuses on a wide variety of dispute resolution matters, including M&A, tax, competition, intellectual property and issues in the transportation and energy sectors.

A Winnipeg native, Marshall attended the University of Manitoba (B. Comm., LL.B.) and was called to the Manitoba Bar in 1966 before becoming a civil litigator in private practice. He was appointed King’s Counsel in 1979. For nearly three decades, he solidified his reputation as one of the country’s leading counsel in numerous high-profile cases.

Marshall was appointed to the Trial Division of the Federal Court of Canada in 1992, was elevated to the Federal Court of Appeal in 1999 and appointed to the Supreme Court of Canada in 2006.

Marshall was appointed a Companion of the Order of Canada in 2017, one of Canada’s highest civilian honours, which recognizes outstanding achievement, dedication to the community and service to the nation.
