Jason GudofskyMcCarthy Tétrault

The ‘diverse group‘ at McCarthy Tétrault advises on the full range of antitrust issues, including merger control, criminal and civil investigations, litigation and class actions, misleading advertising and deceptive practices. The team represents clients across all key industry sectors but is particularly specialised in the airlines, pharmaceuticals, health, IT and TMT sectors. Foreign investment review and national security continue to be key sources of work in the department, with recent work including investments by state-owned enterprises, cultural reviews and national security investigations. Senior partner Oliver Borgers and practice head Jason Gudofsky are both names to note in this area. The group has grown with the arrival of Casey Halladay from McMillan LLP, a move that strengthens the firm’s cartel work, as well as other contentious matters including abuse of dominance. Litigator Donald Houston is retained on cartel investigations and prosecutions, civil cases and private actions.
