You realize that you're talking about "buying Canadian", but dissatisfied that the Canadian broadcaster doesn't have American shows, yes?

The first three seasons of the expanse are on CBC Gem.

I don't watch many police/med procedurals (or much of what you've listed) but they seem to have a few procedurals etc, I think Republic of Doyle is one? Oh, Luther is a detective series and solid stuff, not sure if that scratches your itch? A couple others I don't know much about.. Kind of different and I do love Natasha Lyon so I'm biased but Pokerface seems like a fun take on the procedural.

Mr D is a sitcom, seems on par with Big Bang? Also, they have Portlandia which is sketch comedy but hilarious.

Might be a but highbrow but Reservation Dogs is great stuff.

To each their own though, good luck!

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.
