Between 2013 and 2023, Talking Radical Radio was broadcast weekly on community radio stations across so-called Canada — usually a dozen or so at any given time, though it fluctuated — and was available via a range of online platforms.
There is a chance that the show might return at a later time as a podcast-only project, and you can still find it via SoundCloud, iTunes, Stitcher, and TuneIn. Also, for those of you who are devoted users of YouTube, I posted episodes there for a couple of years.
The show was also available on venerable lefty news sites Rabble.ca (2013-2020) and The Media Co-op (2020-2023). Rabble chose not to preserve its archives of the show, so your best bet for looking through the back catalogue is on this site or on SoundCloud.
