About Roy

Roy carries on a diverse practice with particular experience in Indigenous rights and title, commercial litigation and international trade. Clients appreciate Roy's ability to provide prompt, straightforward and business-savvy advice in areas of the law that are complex and continually evolving.

In the area of Indigenous law, Roy advises private-sector clients across Canada on the development of energy, mining and other major projects, and relationships with Indigenous peoples. He negotiates commercial agreements, impact benefit agreements, consultation protocols and other arrangements with First Nations, Métis and other Indigenous groups. He also assists clients in navigating the regulatory processes necessary to secure project approval, including the implications of UNDRIP, and defends proponents from litigation challenges brought by Indigenous communities and individuals.

Roy has succeeded in all levels of court, including the Supreme Court of Canada, and in arbitration and administrative tribunals. In addition to regulatory matters, he represents clients in construction litigation, contract disputes, injunctions and disputes involving claims of fraud, negligence, defamation, breach of trust and misrepresentation.

Roy joined the Firm in 2000, shortly after clerking for Chief Justice McLachlin at the Supreme Court of Canada.

Roy provides legal services through Roy Millen Law Corporation.
