On today's show: We connected with the University of Calgary's trade expert Carlo Dade to hear what our neighbor's new trade policy could mean for both Canada and the global economy; With all this talk of accessing new markets for Canada's exports, we heard from a local researcher who has spent years studying the idea of energy corridors; The epic rock opera and high concept album "The Rise and Fall of Ziggy Stardust and the Spiders from Mars" will fill the Jack Singer Concert Hall tonight, and we spoke to a guitarist ready to rock out.
