Canada’s constitution is the foundational framework that sets out the powers of government and the rights and freedoms of Canadians and is comprised of written documents, court-made law and unwritten rules derived from custom and practice. When the validity of government action or legislation is called into question, it is essential to be advised by lawyers who understand the constitutional dimensions of an issue.

Our firm has had the privilege of acting on many of the leading constitutional cases of the day, both under the Charter of Rights and Freedoms and the Constitution Act generally.

As such, we have a deep expertise in all areas of constitutional law, including federalism matters, the Charter of Rights and Freedoms and Aboriginal rights. We act for a range of organizations – including public sector agencies, companies, Aboriginal groups, charities, advocacy groups and private businesses – on complex constitutional matters. Among other things, we provide constitutional law opinions and represent parties in constitutional challenges at all levels of court on matters as diverse as the constitutionality of a commercial salmon fishery in coastal British Columbia waters, the constitutionality of corporal punishment, taxing powers of the government, freedom of expression and the constitutional validity of the regulator’s search and seizure powers, to name a few.

We also have a dedicated practice focused on constitutional and administrative law concerning human rights, labour relations and civil litigation.
