Complex class actions require more than class action expertise
Chambers highlights Sotos’ strength in employment, privacy and consumer protection litigation, singles out the firm for its competition and antitrust work, and recognizes its experience in data breach class actions.
Those areas illustrate an important feature of the Sotos practice: many class actions turn on the substantive law, market dynamics, technology or commercial relationships underlying the claim. Competition cases may require close analysis of how a market operates. Privacy and cybersecurity matters can raise complex questions about technology and data governance. Investor claims may depend on financial products, securities law and the obligations of advisors and institutions.
Sotos brings that subject-matter knowledge to the investigation and prosecution of class actions across Canada.
The practice is also moving into new areas of litigation. Current Sotos matters include proposed class actions concerning the alleged use of Canadian artists’ and writers’ copyrighted works to train generative artificial intelligence systems, as well as competition matters involving digital markets and other forms of alleged anti-competitive conduct.
Together, these matters reflect a class actions practice that combines established strength in competition, privacy, consumer protection, employment and investor disputes with the ability to address new legal issues as technology, markets and regulation evolve.
