About

Provided by McMillan LLP

McMillan’s International Trade Practice Group advises domestic and international companies ranging from multinationals to small and growing businesses, helping them steer through unfamiliar laws and regulations, economic sanctions, treaties, tariffs, forced labour obligations and bureaucracy. Bringing a combination of real-time business solutions and tactical excellence, McMillan’s lawyers are also frequently called upon to represent a wide range of companies before international trade decision-makers. As a market leader in Canadian anti-dumping and countervail cases, McMillan has been involved in most such recent Canadian cases. McMillan’s team has a wide variety of key experience. This includes lawyers who have worked within key government organizations, such as Global Affairs Canada and the Canadian International Trade Tribunal. McMillan lawyers have been appointed to the Chapter 19 (Trade Remedies) roster of panelists. Governments also turn to McMillan for assistance with complex international legal issues that require an understanding of political sensitivities. Whether revising laws for a government’s compliance with trade rules under international or Canadian trade agreements, such as the World Trade Organization, Canada-United States-Mexico Agreement (CUSMA, formerly NAFTA) or the Canada Free Trade Agreement, or advising on delicate negotiations affecting regulated or trade protected sectors, McMillan can help governments with international trade issues.
