Edit: Gonna add 2 more I remembered-
Blender - I wish I had more time to learn it, but I did start the infamous “Donut Tutorial” once!
Watch Cartoons Online - Lots of good older stuff!
CBC Gem, which is our country’s public news corporation’s streaming service which is a catalog of Canadian television. There’s also CBC Music which is the radio app, and you can even listen to the live streams of the Metropolitan Opera on Saturdays.
