About Marc Crandall

Marc Crandall is a partner in Gowling WLG's Ottawa office whose litigation work covers three fields: intellectual property, competition and tax. On the IP side, the focus is on patent, copyright and trade secret cases in the pharmaceutical and high-tech sectors. Crandall has taken clients all the way through trial and has appeared before many courts, appellate courts included. Clients range from OpenAI, Google, LG and Takeda to the small and medium-sized businesses Crandall regularly acts for.

Engineering came first. After more than a decade working as a professional engineer, Crandall turned to law, earned a JD at the University of Ottawa and was called to the Ontario bar in 2016. Crandall draws on that engineering background to get up to speed quickly on complicated technology and on how a client's business runs, and to pin down the technical, commercial and legal questions a dispute really turns on. There was also a stint of more than a year at the Department of Justice, where Crandall litigated tax cases for the Crown, and Gowling WLG brought Crandall into its partnership in January 2024.

Competition work has meant several matters before the Competition Tribunal, including acting for the respondents in Apotex v Takeda and JAMP v Janssen, both private applications brought under the Competition Act's expanded abuse of dominance provisions. In tax, Crandall handles disputes at the Tax Court of Canada and the Federal Courts, and the time as Crown counsel informs a push for practical, efficient resolutions.

Crandall also teaches an intellectual property course at the University of Ottawa's Faculty of Law, co-edited Gowling WLG's 2026 Defence Outlook, and has written about AI in Canada's defence and aerospace sectors, the new private access rules under the Competition Act, and how patent costs can be deducted.
