Robert is Co-Chair of Osler’s National Mergers and Acquisitions Practice and Head of the Corporate Department in Osler’s Montréal office. He has previously served as a member of the firm's Executive Committee and was part of the team that opened Osler’s Montréal office in 2001.

Robert advises management teams and boards of directors in connection with a wide range of M&A transactions, including hostile and friendly business acquisitions, special committee mandates, going-private transactions and strategic alliances. Robert is repeatedly recognized as one of Canada’s leading business lawyers, including by Chambers Global, Best Lawyers, Lexpert, IFLR, Who’s Who Legal, Expert Guides and Acritas. Robert also advises on public and private securities financings, corporate governance issues (including for a range of crown corporations) and general public company matters.

Robert’s career with Osler spans 25 years, during which he has participated in some of Canada’s most innovative and ground breaking transactions. He led the Osler team involved in Canada’s largest ever completed leveraged buy-out, as well as the Osler teams involved in the largest private equity deals in Québec in 2014 and 2015. He was intimately involved with implementing the first poison pill in Canada and has since worked with many companies on their M&A defense strategies. He also led the Osler team involved with significant proxy fights that saw the problem of “empty voting” on the part of activist investors receive considerable public scrutiny in Canada.

Robert is a former law clerk to Madame Justice Bertha Wilson of the Supreme Court of Canada and is an Adjunct Professor with McGill University’s Faculty of Law. He has written extensively on business law issues and is also active with a number of boards and charitable organizations.
