I find that the CBC gem newsletter helps. CBC Gem isn't a full replacement to all other streaming platforms but it does help reduce usage of the other ones. It's hard to switch over to Canadian options all at once. Another factor is how difficult it is to hear about content that isn't popular on social media. Even with content that is on a large streaming platform, people will come across it months of years later wondering why people didn't mention it before

CBC gem has a lot of pretty good procedural type shows (ex. police dramas), especially when you mix in the content from the UK, Europe, Australia/New Zealand. There are some good sitcoms too. Schitts Creek and Kim's Convenience are popular, but there's also content from american networks like Animal Control.
