McCarthy Tétrault LLP is a law firm with offices in Canada’s major commercial centres and in London, UK. It provides business law, litigation, tax, real estate, and labour and employment law services. It is one of the Seven Sisters (law firms) in Canada.
The firm represents Canadian and international clients, including major public institutions, financial services organizations, mining companies, manufacturers, pharmaceutical companies and other corporations.
McCarthy Tétrault’s London office specializes in assisting clients with their transatlantic transactions, and is staffed with both English and Canadian-qualified lawyers. A charter member of the Canada-UK Chamber of Commerce, it provides services in Europe, Africa and the Middle East.
McCarthy Tétrault was created through the merger of several firms: McCarthy & McCarthy of Toronto, Clarkson Tétrault of Montreal, Shrum Liddle & Hebenton of Vancouver, and Black & Company of Calgary.
This merger was initially denied by the Law Society of Alberta, which enacted rules designed to stop it. The rules prohibited members from entering into a partnership with anyone who was not a member ordinarily resident in Alberta, and prohibited members from being partners of more than one firm. This rule was challenged as being contrary to the mobility rights protected by the Charter of Rights and Freedoms.
