    2026-07-01 | 54 mins.

IDEAS shares this 1992 award-winning documentary about "The Idea of Canada," which includes music compositions inspired by Glenn Gould. Composer Christos Hatzis discusses the relevance and meaning of how "Canada allows you to be patriotic."

    2026-06-30 | 54 mins.
    At the surface, Bear is about a woman who develops a sexual relationship with a bear. And though the 1976 novel earned Marian Engel a Governor General's award, it's been largely forgotten. Contributor Melissa Gismondi explores its mystery, meaning and relevance today. *This episode originally aired on January 4, 2021.

    The best comedians in the U.S. are Canadians

    2026-06-29 | 54 mins.
    Canada produces legendary comedians and comic actors who excel on the world stage. So why is Canada not known for comedy? Does it have something to do with our proximity to the U.S., the way there are so many Scottish comedians performing in England? Three comics discuss Canadian comedy and what Canada's profile would be on a dating app — as part of the Provocations-IDEAS festival.

    Comedians in this episode:

    Debra McGrath is a comedian, writer, and director whose comedy began with Second City Improv. She is best-known for roles in Little Mosque on the Prairie, Seven Little Monsters and Paradise Falls.

    Stewart Reynolds (aka Brittlestar) is a Stratford, Ontario-based comedian. His work has brought him to the White House, and to meeting the Prime Minister. He's the author of The Subtle Art of Resistance: Lessons From Cats For Surviving Fascism.

    Martha Chaves has made many TV appearances including Just for Laughs, We’re Funny That Way Festival, and the Winnipeg Comedy Festival — and she’s often been heard on CBC's Laugh Out Loud, The Debaters, Because News — and now IDEAS.

    The 33,000 Horsepower Gamechanger | The Greatest Numbers of All Time

    2026-06-25 | 54 mins.
    There is nothing random about featuring 33,000 in our number series. It's very powerful. So much so, that the number put millions of horses out of work. Inventor James Watt used “33,000 foot-pounds a minute" to measure the capabilities of a horse when trying to market his new and improved steam engine. The engine was a big success, saving horses from the drudgery of manual labour. Now, a similar process is underway with artificial intelligence — but are we the horses, or the steam engine? *This episode is part of our series, The Greatest Numbers of All Time.
