Susan M. Hutton - Stikeman Elliott LLP

Within: Competition and antitrust

‘Top-tier competition shop’, Stikeman Elliott LLP is ‘head and shoulders above the rest’, according to some. Highlighted as ‘extremely strong on the litigation side’, due in no small part to ‘first-class competition litigator’ Katherine L. Kay, the group also excels in major merger reviews, complex behavioural matters and foreign investment work. High-profile department head Paul Collins is a ‘sophisticated operator’ and acted with Ottawa’s Susan M. Hutton to advise Bayer on its headline $66bn acquisition of Monsanto. In another transactional file, Collins is advising Airbus on its partnership with Bombardier and Investissement Québec for the C Series aircraft program. On the investigations front, the ‘increasingly prominent’ Eliot Kolers is representing Sobeys in the Bureau’s investigation into alleged price-fixing in the bread market. In a headline contentious case, star litigator Kay is representing CIBC in a set of class actions brought against several banks and credit card companies alleging anti-competitive conduct in the setting of interchange fees. Michael Kilby, who advised Cheung Kong Property Holdings on its C$2.8bn acquisition of Canadian Reliance Home Comfort, is also recommended. Named partners are based in Toronto unless otherwise stated.
