During his more than 35 years of practice as a senior partner at two of Canada’s most prestigious national law firms, Riyaz has developed considerable, sophisticated, and wide-ranging experience in International Trade and Investment Law.

This includes international investment arbitrations, international trade disputes (including before NAFTA panels, the WTO, and domestic courts), trade remedies, international trade regulations (economic sanctions, export controls, customs), trade policy and market access, government procurement, national security, corporate investigations, and anti-corruption.

Since the beginning of his career in International Trade and Investment Law, prominent legal directories in Canada and internationally have recognized Riyaz as a leading practitioner in his field. His global standing is confirmed through his selection by the International Who’s Who of Business Lawyers early in his practice as one of 30 lawyers worldwide “with proven expertise in international trade law.” Beginning with the inaugural issue, Chambers Global ranked him at the highest level, while also noting that he is “widely credited for having created one of the most active and international practices out there” and for the “impressive breadth” of his practice. For the past 15 years, the Canadian Who’s Who has recognized Riyaz for his achievements in the field of International Trade and Investment Law.

The Federal Government of Canada has appointed Riyaz for a ten-year term on the roster of panelists for the NAFTA Chapter 19 binational dispute resolution process now Chapter 10 of the USMCA.
