Guy Régimbald

Guy Régimbald is a partner in Gowling WLG's Ottawa office, and the National Practice Group Leader of the Administrative Law Practice Group. Guy’s practice specializes in the areas of constitutional and administrative law, Aboriginal law, trademark and copyright law, and taxation.

As a member of Gowling WLG's Supreme Court of Canada Services Group, Guy has appeared as lead counsel or co-counsel before the Supreme Court of Canada in many high-profile cases, and been involved as agent or adviser in many more. Guy prepares applications for leave to appeal to the Court, represents clients on appeals and motions, and guides clients through all the stages of the Supreme Court process.

A prolific writer, Guy is the author of Canadian Administrative Law (3rd edition, 2021) and co-author of The Law of the Canadian Constitution (2nd edition, 2017), two major treatises published by LexisNexis that have been cited by the Supreme Court of Canada and other courts throughout Canada in many reported decisions. Guy is also a co-author of Supreme Court of Canada Practice (Carswell), the definitive guide to practice and procedure at Canada's highest Court.

In his constitutional and administrative law practice, Guy advises clients on issues related to the division of powers and the Canadian Charter of Rights and Freedoms. He also advises clients on other government and regulatory issues, including on lobbying requirements that may arise in government relations.

Guy's Indigenous law practice is focused on Indigenous and treaty rights, self-government, consultation and accommodation, as well as First Nations taxation. He advises and represents First Nations, Inuit and Métis communities across Canada.

Guy has been recognized by the Canadian Legal Lexpert Directory for his work in Indigenous Law and Litigation – Public Law, by Best Lawyers in Canada in Administrative and Public Law and in Appellate Practice, and by Managing Intellectual Property as a star in copyright law and/or trademark.

Guy currently serves as Chair of the Administrative Law section of the Canadian Bar Association, having served on the executive since 2016. He is also a member of the executive of the CBA Constitutional and Human Rights Law Section since 2016. Guy has also been elected as Chair of the Canadian Bar Association's Federal Courts Bench and Bar Liaison Committee, where he has been serving as a member since 2018.

Prior to joining Gowling WLG, Guy clerked for the Honourable Mr. Justice Rothstein and the Honourable Mr. Justice Major of the Supreme Court of Canada, as well as for Mr. Justice Marc Noël at the Federal Court of Appeal (now Chief Justice).
