Suddenly realising most of my podcast lineup is US-based - but here are a few Canadian standouts:
'Tech Won't Save Us' is a fantastic tech-critical podcast;
'Theory & Philosophy' is David Guignion, from Montreal(?), doing excellent and accessible explanations of a wide range of thinkers;
'The Breach Show' is journalists Desmond Cole and Martin Lukacs talking about Canadian politics from a left perspective.
Edit: Oh, and Front Burner is a relatively listenable CBC politics podcast.
