For those interested, Canada has made several shows with WLW rep:
Lost Girl: the most explicit one that I can think of right now. The main character is a bisexual succubus, and they did not shy away from the concept.
Orphan Black: one of the characters is a lesbian (she's not the lead, but Cosima's definitely a main character), and has an on again, off again, relationship with another character.
Wynnona Earp: I haven't watched it, but the lead character's younger sister (also a main character) is a lesbian.
Killjoys: I haven't seen this one mentioned in the notes, probably because the WLW characters are only major recurring characters instead of mains, but they are *major* recurring characters, especially in the last couple seasons. It's also by the same creators as Lost Girl.
Stargate Universe: A co-production with the US. The first Stargate show to have a lesbian main character.
Slo Pitch: a Canadian web series about a queer softball team that is adapted into a tv show set to start airing sometime this year. I haven't seen the web series, and the tv show isn't out yet, so I can't really speak to the representation.
Saving Hope: one of the mains, Dr. Maggie Lin, comes out as bisexual in Season 3 (although it doesn't come up as much as one might hope).
Queer as Folk (North America): a Canadian co-production with the US. I think two of the main characters are a WLW couple, but I haven't watched it.
Honourable mentions (either queer rep that isn't WLW, or minor LGBTQ characters):
Sort Of: a non-binary, first generation Pakistani-Canadian navigates cultural expectations and their identity.
Schitt's Creek: one of the main characters, David Rose, is bisexual.
Sanctuary: the lead, Dr. Helen Magnus, is confirmed bisexual in the last season, but the show ended before it went anywhere, so... honourable mention.
Murdoch Mysteries: one of the recurring characters Dr. Emily Grace, was confirmed bisexual in Season 8, but left the next season (I also hate her love interest, but that's not really relevant). Another recurring gay character, Det. Llewellyn Watts, was introduced in Season 10, but wasn't confirmend gay until Season 13. I want to take this opportunity to say that Watts is great, and formally petition gor him to be promoted to a main character.
Heartland: Apparently had it's first gay character in Seasons 14-18? Idk, I haven't watched it since I was a kid.
None of the above are as explicit as Heated Rivalry (except maybe Slo Pitch? Idk, it's not out yet), but Canada has been funding queer media for a while now, and it's great that people from other countries are seeing it!
(As an aside, it's super funny that people are so fixated on the "Government Funded" aspect. Pretty much everything that's filmed in Canada gets government subsidies. That's also why a lot of US shows are filmed here.)
