Overview

Content is provided by the firm.

Cassidy Levy Kent is an international law firm with offices in Washington and Ottawa. Our practice is focused on helping our clients address international trade and investment issues — whether they involve U.S. or Canadian trade controls, trade remedy litigation, dispute settlement proceedings under the World Trade Organization (WTO) and bilateral and regional free trade agreements and investment treaties, or negotiations and other policy efforts.

The lawyers at Cassidy Levy Kent have decades of experience as partners in the international trade and investment practices at some of the largest, and most prestigious, law firms in Canada and the United States. We started our firm with the objective of combining the experience and high-quality service for which large firms are known with the flexibility and personal attention of a smaller firm.

Our policy experience includes developing and implementing bilateral, regional and multilateral negotiating strategies, and assisting clients to ensure that their interests are adequately protected in the final legislative and regulatory implementation. Our U.S. lawyers have worked on every major U.S. bilateral, regional and multilateral negotiation since the GATT Tokyo Round, as well as all major U.S. trade legislation since the Trade Act of 1974. Our Canadian lawyers have served as advisors in the Trade Law Bureau of the Department of Global Affairs Canada, and have litigated a variety of WTO, NAFTA (now USMCA), and other trade disputes.

Our attorneys advise clients on a broad range of international trade and investment issues under U.S., Canadian, and international law. We have a proven record of success in U.S. and Canadian enforcement proceedings involving customs, export controls, and economic sanctions. With respect to trade remedy litigation, our lawyers and professionals have worked on literally hundreds of cases, and we have extensive experience with the full range of legal, economic and accounting issues arising in these proceedings.

Our approach is to provide our clients with detailed, hands-on involvement in matters that is based on years of experience and expertise to add value directly to the issues our clients face and the strategies they develop. Our commitment to cost-effective staffing allows us to handle even the smallest matters efficiently. At the same time, by using the network of relationships we have built up over the years, we have the ability to assemble the most effective teams of lawyers, economists, and public and government relations experts available.
