He specializes in cross-border compliance and dispute resolution under trade agreements, investment treaties and Canadian law. He assists business and government clients from around the world in trade negotiations and disputes under agreements such as the WTO Agreement, the USMCA and the CPTPP; in trade remedy proceedings; and in navigating economic sanctions and export control laws.     

Matthew has led legal teams in WTO panel and Appellate Body proceedings in matters involving subsidies, dumping, sanitary and phytosanitary measures, technical barriers and tariffs, and in investment arbitrations under the NAFTA.

Matthew was previously Director-General of the Government of Canada’s Trade Law Bureau (from 2009-2012) and served in the Bureau for fifteen years.  He was Canada’s chief legal counsel in the negotiation of the CETA with the European Union and various other trade and investment treaty negotiations. He began his career as a foreign service officer, including a posting to the Canadian Embassy in Washington, D.C., where he focused on trade and economic sanctions legislation and trans-border resource and environmental issues.
