The new USMCA trade agreement, which is set to replace NAFTA, was signed this week and is now waiting to be ratified by Canada and the USA before coming into full effect. The deal's final terms included some last-minute changes, such as new rules about exclusivity for biological drugs, stricter enforcement of labour standards, and tougher requirements for rules of origin on steel and other materials used in auto manufacturing. Canada's Deputy PM Chrystia Freeland called the deal a "progressive" agreement to replace NAFTA, but will it really help Canada's economy in the long run? Are the changes positive for Canadian industries? To discuss these questions, John is joined by Colin Robertson, vice-president with the Canadian Global Affairs Institute and part of the team that negotiated the original NAFTA.
