Robert Yalden is the inaugural holder of the Stephen Sigurdson Professorship in Corporate Law and Finance. Prior to joining Queen’s Law in 2018, Robert was a senior partner with Osler, Hoskin & Harcourt LLP and an Adjunct Professor with McGill Law.

Robert’s publications and teaching span 30 years. He has focused particularly on the forces that shape competing perspectives (both domestically and internationally) on the roles and responsibilities of corporations, boards of directors and different stakeholders, and that in turn influence the institutional structures that countries put in place to oversee and foster the evolution of business law.

After clerking for Justice Bertha Wilson at the Supreme Court of Canada (1989-90), Robert was called to the Bar in Ontario (1991) and Quebec (1992). He joined Osler’s Toronto office in 1993, became a partner in 1998, and was part of the team that opened Osler’s Montreal office in 2001. Fluently bilingual, he served as a member of Osler's Executive Committee, as Co-Chair of Osler’s National Mergers and Acquisitions Group for over a decade and as the head of the Corporate Department in Osler’s Montreal office. Repeatedly recognized as one of Canada’s leading business lawyers during his 25 years in practice, Robert worked closely with senior management teams and boards of directors in shaping some of Canada’s most innovative and ground-breaking transactions.
