About Berger Montague (Canada), P.C.
Berger Montague (Canada) is a Toronto firm whose focus is investors caught up in shareholder disputes that cross borders. It regularly acts for both institutional and retail investors, whether they're in Canada, England, France, Germany, the Netherlands or the United States.
The firm is an Ontario professional corporation regulated by the Law Society of Ontario, and it's affiliated with Berger Montague PC, which David Berger started in Philadelphia in 1970 after serving as that city's solicitor, pioneering class actions in antitrust and securities cases. The Canadian practice took shape through an amalgamation with a Canadian firm devoted to shareholder litigation, one that had spent more than ten years representing investors and was ranked in the ISS SCAS Top 50 from 2017 to 2021.
Albert Pelletier is the Canadian firm's CEO. Holding degrees in both English common law and French civil law, Albert Pelletier was once trial counsel in the Ontario Securities Commission's Enforcement Division, prosecuting insider trading and market manipulation. Senior Counsel Tyler Planeta has appeared at every level of court in Ontario and British Columbia and at the Supreme Court of Canada, while Vincent DeMarco's appearances include Alberta's Court of King's Bench and Court of Appeal as well as Ontario's Court of Appeal and Commercial List. Associate Edwina Mayama is fluent in French and English.
The firm brings securities class actions in Canada for investors who've been harmed, often alongside proceedings in the United States. Many of those cases are taken on a contingent fee, so nobody in the class, plaintiffs included, pays legal fees or court costs unless money is recovered.
Practice areas
Securities class actions for investors
The firm's lawyers have worked on securities class actions in Canada and the U.S. involving Amaya, Concordia International, FSD Pharma and Valeant Pharmaceuticals. Albert Pelletier's class action work carries these claims through leave to proceed under the provincial Securities Acts, certification under the Class Proceedings Act and court approval of settlements. In January 2025 investors retained the firm for a shareholder class action against Telus International (Cda) Inc.
Shareholder disputes for institutions, families and individuals
Pension funds, family offices and individual clients all turn to the firm across a broad range of shareholder disputes. Its managing lawyers have represented institutional and governmental investors such as state and city pension funds and pension trusts, and they also stand up for individual investors, from high-net-worth clients to people of modest means.
Cross-border antitrust and competition claims
The firm has extensive experience with antitrust litigation that crosses borders, alongside its securities work. Tyler Planeta's class action practice centres on securities and competition matters, and earlier, at a Dublin litigation funding firm, Tyler Planeta helped manage securities and competition claims in Europe and Asia.
