    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.
