Riyaz advises multinational and domestic businesses on international trade policy and investment matters, international trade strategies and market-access concerns. On international trade regulations, he advises on all aspects of economic sanctions, export and import controls, national security, anti-bribery laws, government procurement, customs laws, transfer pricing and trade remedies such as anti-dumping, countervailing and safeguard measures.

A significant part of Riyaz’s practice focusses on assisting clients operating overseas that have to contend with political risks, anti-corruption and corporate social responsibility obligations. Among Riyaz's current clients are several mining and oil & gas companies including, two of the largest gold companies in the world, and Canada’s largest independent oil companies with significant international presence.

Riyaz also acts as counsel in international trade and investment disputes involving the application of trade laws and regulations and the enforcement of treaties. He has acted as counsel from the time of the very earliest WTO disputes concerning Canada, and the first two investment arbitrations under Canada’s bilateral investment promotion and protection treaties. During his more than 25 years of practice, Riyaz has advised and represented leading businesses in a full range of industry sectors.

Riyaz is consistently sought out as an expert source by Canada’s two national daily newspapers (The Globe and Mail and National Post) and several legal and industry publications to comment on current developments in anti-corruption laws, economic sanctions, free trade agreement negotiations and other international trade events affecting Canadian businesses.

    Riyaz has been counsel in more than 50 Canadian and international trade remedies proceedings (and one-third of all initial investigations commenced since 1992 under Canada’s trade remedies laws), 13 challenges under Chapter 19 of NAFTA and the Canada-United States Free Trade Agreement (including one-half of all Canadian proceedings under NAFTA that were completed) and in excess of 40 proceedings before the Federal Court of Canada. He has acted in most of the significant trade remedies cases litigated in Canada, and has also argued landmark cases before NAFTA Panels and the Federal Court of Canada.
