Since we're doing Buy Canadian, what's some Canadian media worth checking out?

Trailer park boys, letterkenny and travelers are all canadian shows.
- Schitts Creek and Kim’s Convenience! And Baronness Von Sketch.

It's a video game, but I've been playing Sea of Stars, an indie game made in Québec with Chrono Trigger vibes.
Not sure if it's available for purchase without going through Steam though, but at least the studio is local.

The Walrus, an independent magazine with long forum journalistic stories. https://thewalrus.ca/
Canadian news is in danger. Our sources are primarily owned by right-wing Americans. We need to protect CBC and publications like the Walrus.
- Also Canadaland

The Debaters. There are so many seasons going back years, and most of them are hilarious.

Universe Today is a space themed science publisher based on Vancouver Island, all their stuff is ad free on patreon even with the free tier.
They have written articles, YouTube, mastodon, blusky, and podcasts.

Hope you don't mind a non Canadian answering and you didn't mention games, but i just finished 1000xResist a few weeks ago and recommend it.

Adding to the question, keep an eye out for any songs by Canadian artists! We can submit the best ones in the next !lemmyvision@jlai.lu

Learned about Norman McLaren at San Francisco State's film school decades back.

For TV there's Murdoch Mysteries.
For music I could go on for a long time!
For rock there's Billy Talent, The Beaches, Alexisonfire, Tokyo Police Club, City and Colour, Arcade Fire, Arkells, Barenaked Ladies, Metric, Hotel Mira, Mother Mother, Sum 41, The Trews, The Strumbellas, The Zolas. That's just what I can see in my CD collection. For electronic music there's Deadmau5 but he's well known already.
- Don't forget ReBoot, Hilarious House of Frightenstein, and Sex with Sue!
  Bonus points for Ed the Sock

More small scale but LoadingReadyRun for MTG or gaming stuff is good.
- LRR is worth supporting no matter your nationality. They're great.

not canadian, but have enjoyed The Frantics, Red Green, Labatt's and your lumber is top notch
- Labatt's isn't Canadian. Not anymore. Owned by Anheuser-Busch, US-Belgian-Brazilian multinational drink and brewing company based in Leuven, Belgium
  
  Drink local craft beer instead!

Fubar, Carts of Darkness, The Delicate Art of Parking.
- Carts Of Darkness is an incredible documentary; in my opinion. Could not recommend it enough.

For authentic Canadian, you simply have to crack open a two-four of Labatts while watching the kids in the hall with The Tragically Hip playing softly on the stereo in the background. (we miss you Gordie)
