IDEAS is a place for people who like to think. If you value deep conversation and unexpected reveals, this show is for you. From the roots and rise of authoritarianism to near-death experiences to the history of toilets, no topic is off-limits. Hosted by Nahlah Ayed, we’re home to immersive documentaries and fascinating interviews with some of the most consequential thinkers of our time.

With an award-winning team, our podcast has proud roots in its 60-year history with CBC Radio, exploring the IDEAS that make us who we are.
