About Tyr LLP

Tyr LLP is a litigation firm in Toronto, founded in May 2019 by three partners, James Bunting, Sean Campbell and Jim Doris, who left Davies Ward Phillips & Vineberg to start their own firm. Rather than naming the practice after its founders, the group named it Tyr, after the Norse god of law and justice, a choice meant to reflect a collaborative, team based approach rather than a hierarchy built around any one name.

The firm's docket spans commercial litigation, arbitration, class action defence, insolvency and creditor disputes, investigations and regulatory defence, and intellectual property litigation covering patents, life sciences, copyright and trademarks. It also acts for both employers and senior executives in executive employment disputes, and for shareholders in securities matters. A dedicated Tyr Sports team represents athletes, coaches, agents and sport governing bodies, including cases before the Court of Arbitration for Sport in Lausanne, Switzerland, and can advise clients in English, French, Spanish and Russian.

Tyr grew from three founding partners to roughly twenty lawyers within its first few years, adding lateral hires from other Bay Street practices along the way. It has been based on Wellington Street West, in Toronto's King-Spadina neighbourhood, since relocating there in the early 2020s.
