Individually, and as a collaborative team, we deliver strategic and thoughtful representation.


For four decades, we have represented both individual and corporate clients in difficult and complex cases at all levels of trial and appellate court. Our lawyers routinely appear before the Supreme Court of Canada, the Court of Appeal for Ontario, the Divisional Court, as well as superior and provincial trial courts across the province.

GHW conducts trials and appeals across Canada. At the core of our practice is a focus on criminal law and related regulatory and administrative litigation.

We are deeply committed to active membership in our community, through pro bono work and as contributors to the legal profession through mentorship, academic writing and teaching, and continuing legal education.

Our counsel has been sought, and we have worked in collaboration with, colleagues across Canada and the United States as well as with firms in Europe and Asia. We provide skilled and insightful advocacy that has earned us a reputation for success and discretion.

Led by partners Brian Greenspan, David Humphrey, Seth Weinstein, and Jill Makepeace, our experienced team handles a broad range of criminal and regulatory matters.

Our sound advice and experience has been relied upon in domestic, international, and trans-border criminal and regulatory investigations and proceedings.
