Osler’s National Disputes team advises on and solves business-critical issues for Canadian, as well as global, organizations.
Best known for handling multijurisdictional class actions and complex corporate/commercial litigation, we defend major institutional clients on high-profile (“bet-the-company”), precedent-setting cases across various industries and at all levels of courts in Ontario, Alberta, Québec, British Columbia and most other provinces, as well as in the Federal Court and the Supreme Court of Canada. We regularly appear in hearings before a variety of provincial and federal tribunals, such as the Financial Services Tribunal, the Ontario Municipal Board, the Environmental Assessment Board and the Ontario and Alberta Securities Commissions and represent clients in various forms of alternative dispute resolution.
While always ensuring our clients are litigation ready, we help our clients develop effective risk management strategies to proactively address potential exposures and mitigate the threat of complex litigation. However, when litigation is unavoidable, we defend our clients in a strategic, coordinated and cost-effective manner. Osler’s Dispute Resolution & Risk Management team has experience in all types of disputes including constitutional and public law, corporate governance, securities, defamation, energy and natural resource, environmental, franchise, consumer protection, intellectual property, privacy, pension and benefits, product liability, professional negligence, tax disputes and white-collar defence. We also leverage the expertise of Osler Works – Disputes, our specialized litigation support group composed of multidisciplinary professionals with dedicated expertise in legal technology, process improvement and management, project management and eDiscovery services.
