Class Actions
The potential risks of a class action lawsuit extend far beyond damage to a company’s bottom line. Brands can be tarnished, employees may become demoralized and markets can punish share prices. McMillan’s class action litigators work tirelessly on our corporate clients’ behalf to defeat claims early to avoid these and other pitfalls.
Our lawyers have broad experience in major domestic, cross-border and international class actions. Our highly accomplished litigators have expertise in a broad range of class action specialties. These include antitrust and competition, fraud, product liability, consumer protection, securities, employment, pharmaceuticals and medical devices, automotive, intellectual property, environmental, and banking litigation. Our prime focus is to preserve shareholder value and public reputation by defeating claims early.
Our law firm has handled some of the biggest domestic, cross-border and international class actions. McMillan’s lawyers across Canada work as one team, in collaboration with trusted cross-border connections, to seamlessly and effectively handle multijurisdictional cases. Our litigators have worked with many of Canada’s leading corporations and defended claims of varying sizes and degrees of complexity.
As one of Canada’s most highly reputed class action law firms, McMillan helps corporate clients by counselling on early resolution options, including defeating class treatment, seeking dismissal or summary judgements, and negotiating settlements; defending against class actions in the courts; managing the discovery process; creating strategies that mitigate risk across multiple business areas, including public relations, finance and human resources; and advising on the Canadian implications of suits originating in the United States.
