Cassels Brock & Blackwell LLP is a Canadian law firm focused on serving the advocacy, advisory, and transactional needs of the country’s most dynamic business sectors.

Cassels brings a rare depth and breadth of experience to both the negotiating table and the courtroom. We offer recognized expertise in resolving complex legal  issues, pride ourselves on developing inventive and effective means of solving problems, and have a reputation for assertive and efficient settlements built on a track record of favorable motion and trials decisions – counsel know that we are ready, willing, and able to go all the way to court.

Our litigators represent clients at all levels of federal and provincial courts including the Alberta, BC, and Ontario Courts of Appeal and the Supreme Court of Canada. Cassels also boasts one of the country’s leading class action defence teams - we successfully defended the first-ever class action in Ontario and have maintained our position as a market leader with precedent-setting class action defence work ever since. As your strategic advisors, our approach to litigation focuses on two things – reputation and success.

Cassels offers one of the largest law practices in Canada, advising clients from start-ups to multi-national organizations—across the street and around the world—and we are consistently cited as market leaders by such authorities as Chambers, Lexpert, and Best Lawyers.

We are dedicated to staying on the leading edge of trends in law and business to offer practical and flexible solutions to any legal challenge.
