Corporate and Commercial Litigation

Overview

Osler’s litigation practice is one of the largest and most accomplished in Canada. Years of careful recruiting and rigorous training have allowed us to develop deep expertise in complex corporate and commercial litigation. As experienced trial and appeal lawyers, our litigators appear as counsel in all levels of courts in Ontario, Alberta, Québec and most other Canadian provinces, as well as in the Federal Court and the Supreme Court of Canada. We also participate regularly in hearings before a variety of provincial and federal tribunals, including: the Financial Services Tribunal, the Ontario Municipal Board, the Environmental Assessment Board, the Ontario Securities Commission, and the Autorité des Marchés Financiers (AMF).

In addition to our trial expertise, we assist clients in identifying and mitigating risks that could lead to new legal exposures. We focus on developing a deep knowledge of each client’s business, which enables us to intervene effectively to avoid lengthy proceedings or to achieve cost-effective and innovative solutions through early prevention or alternative dispute resolution. Our discovery management specialists work strategically with our litigators and clients to deliver an array of customized, cost-effective and efficient discovery solutions. In short, Osler is home to a critical mass of top litigators in their respective fields — with the track records and the loyal and growing client base to prove it.
