Commercial litigation represents the heart of our practice. Our lawyers have a wealth of experience in pursuing complex, high-profile and often highly confidential cases across the spectrum of business-related legal matters.

Our well-honed courtroom skills have won the respect of judges and fellow counsel at all levels of the courts – including the Toronto Commercial List, where many of Canada's most complex commercial cases are heard.

A significant part of our work has cross-border and international elements. We have relationships with leading firms in every jurisdiction.
