Osler, Hoskin & Harcourt LLP is one of Canada's top law firms for tax according to international and domestic research studies. It is ranked in the top-tier of leading firms and placed five lawyers as leading individuals in various categories including tax controversy, transfer pricing, capital markets, cross-border structuring and M&A. Other international and domestic surveys laud the group of 60 specialists. Our tax group plays an integral role in our M&A practice, often developing novel transaction structures. We are at the heart of most innovative international transactions, whether representing a Canadian multinational with worldwide interests, or the Canadian operation of an international parent. In both instances, tax strategy spans jurisdictions and needs to respond to global–and local–objectives. Our offices are located in Toronto, Montréal, Ottawa, Calgary and New York.
