In this power-packed episode of The Food Professor Podcast, hosts Michael LeBlanc and Dr. Sylvain Charlebois bring listeners up to speed on one of the most complex and fast-moving stories in the global food and agriculture sector: the unfolding international tariff war. Appropriately titled “The Global Tariff War Edition,” this episode features a timely and incisive interview with Mark Warner, Managing Director at MAAW Law and one of North America’s leading experts on trade, investment, and competition law.
The conversation kicks off with Michael and Sylvain diving into the latest developments in U.S.–China trade tensions, which have seen tariffs skyrocket to 125% on inbound U.S. goods into China. They explore the ripple effects on key commodities like soybeans and canola, discuss the surprising resilience of commodity markets, and examine why Canada isn't positioned to step in as a major alternative supplier.
The hosts also explore cultural signals from the food world, including the increasing trend of Americans packing lunches and the declining use of doggy bags in restaurants—signs Sylvain suggests may point to growing economic insecurity and workplace anxiety.
In the second half of the show, Michael and Sylvain sit down with Mark Warner, who brings deep legal and historical context to the tariff debate. Warner unpacks how the Trump administration is using the rarely-invoked International Emergency Economic Powers Act (IEEPA) to sidestep traditional trade channels. He outlines the risks and potential rewards for Canadian agri-food exporters navigating this new landscape, and why subtle diplomacy—not headline-grabbing bravado—may serve Canada better in the long run. From trade agreements and geopolitical strategy to supply management and softwood lumber, Warner’s nuanced take is essential listening for anyone working in, or watching, the agri-food space.
And there’s also a moment of celebration: Dr. Sylvain Charlebois shares his recent honour—receiving the prestigious Charles III Coronation Medal from the Lieutenant Governor of Quebec. In a heartfelt reflection, he dedicates the medal to his wife, Janelle, recognizing her essential support in his research and public policy work. It’s a well-deserved acknowledgment of Sylvain’s national impact on food policy and scholarship.
With sharp insight, humour, and a dash of royal recognition, this episode offers listeners a blend of timely news and expert analysis that defines The Food Professor Podcast.
