David is a member of the Competition, Antitrust and Foreign Investment Group.

David provides strategic advice on all aspects of Canadian competition law, particularly with respect to complex mergers (including in regulated industries), mergers involving reviews in multiple jurisdictions, alleged cartels and alleged abuses of dominance (including involving technology and intellectual property).  David also provides advice on mergers subject to the Investment Canada Act.

David has particular expertise translating the latest international competition law developments into strategic advantages for his clients and their interests in Canada.  David’s knowledge of international developments originates from his years spent practicing with a leading international law firm in Brussels, and his experience before competition law agencies in the United States, the European Union and elsewhere.

David’s recent experience before the Competition Bureau includes:

  • Domestic Transactions.  Advising Linamar Corporation in connection with its C$1.2 billion acquisition of the MacDon Group of Companies.
  • International Transactions.  Advising Newmont Mining Corporation in connection with its US$10 billion merger with Goldcorp Inc., Altria Inc. in connection with its C$2.4 billion minority investment in the Cronos Group Inc., Essilor International S.A. in connection with its €46-billion combination with Luxottica Group S.p.A. and Henkel AG & Co. KGaA in connection with its US$3.6 billion acquisition of The Sun Products Corporation.
  • Behavioral Matters.  Advising a Canadian client in defence of a non-public abuse of dominance investigation by the Competition Bureau, and advising an international client in defence of allegations by the Competition Bureau concerning an agreement among competitors.

David was recognized as one of the five most highly regarded North American practitioners by Who’s Who Legal: Competition – Future Leaders 2018, which profiles the foremost practitioners in the competition community under 45.  Clients describe David as “a sharp thinker with great analytical capabilities,” and praise his “straightforward practical advice.”  In 2017, David was the only Canadian lawyer nominated by Global Competition Review for its Lawyer of the Year – Under 40 award.

David is an active member of the Canadian competition law community.  He has been a professor at Osgoode Hall Law School and served as chair of several committees of the Canadian Bar Association's National Competition Law Section.

Before joining Goodmans in 2018, David practised at another large Canadian firm.
