The battle over a digital services tax has been the subject of Law Bytes podcast episodes for several years as the Canadian government signalled its intent to move ahead with one even as US officials warned of risks of trade retaliation if they did so outside of an international framework. With the DST now in effect, what does trade law have to say and how might the US respond? Meredith Lilly is a full Professor and Simon Reisman Chair in International Economic Policy at Carleton University’s Norman Paterson School of International Affairs. She joins me on the podcast to discuss the current digital trade policy tensions, what our agreements say about complaints and retaliation, as well as explain why a U.S. response on at least the DST seems likely.
