Cassidy Levy Kent was recently recognized by Chambers and Partners as a 2026 “Global Market Leader” in its Global Guide covering the field of International Trade law. Separately, the firm’s three offices — in Washington, Ottawa and Brussels — were each ranked by Chambers as industry-leading legal practices in the United States, Canada, and Europe.
The recognition in Chambers’ 2026 Global Guide covering international trade practices is notable given that only 14 firms worldwide merited Chambers’ recognition. The Chambers USA 2026 guide — released last week — commended the firm’s Washington team as leaders in International Trade law and Customs law. This announcement continues the momentum of Chambers’ rankings of the firm’s Ottawa International Trade and Public Procurement practice groups — each of which was proclaimed a legal industry leader in the Chambers Canada 2026 guide — and recognition of the firm’s Brussels team in the Chambers Europe 2026 guide for their strong capabilities in International Trade and WTO practice.
Between the Chambers USA 2026 guide, Chambers Canada 2026 guide, and Chambers Europe 2026 guide, the ranking agency also named 11 CLK partners as individual leaders in their fields of practice.
Chambers’ continued recognition of the firm follows recent top rankings from other guides such as The Legal 500, Best Lawyers, and Who’s Who Legal. The Legal 500 recognized CLK Canada as an “Elite Boutique” and named it among its top firms for International Trade and Public Procurement. Best Lawyers recognized CLK’s U.S. office for both International Trade and Finance Law and Government Relations Practice. The Legal 500 celebrated the firm’s Brussels office as leaders for the team’s Customs, trade, WTO, and anti-dumping practice.
