After an explosive press conference, a mineral deal between the United States and Ukraine is off the table for now. What does this mean for a war that has been going on for 3 years now? What's next for Ukraine? And how does a shifting geopolitical landscape affect countries like Canada? We've booked Paul Goode. He's an Associate Professor and McMillan Chair of Russian Studies at the Institute of European, Russian and Eurasian Studies at Carleton University. Ann Fitz-Gerald is the Director of the Balsillie School of International Affairs and a Professor in Wilfrid Laurier University's Political Science Department. They'll both take your questions!

What questions do you have about an increase in early onset cancers?

Tim Caulfield is a Law professor and research director of the Health Law Institute at the University of Alberta, and an expert in medical misinformation. He'll be among the guests who will be on the show.
