An arts high school in Toronto. Mostly known for their "welcoming and open" atmosphere and (mediocre at best) art students. They also have an extreme weed culture.

Rosedale Heights' students can be easily identified if they're wearing one of the following:

- Cosplay-esque attire
- Rock/Pop shirts of obscure artists
- Bright and flashy clothing
- LGBTQ/Rainbow attire

Something that's not commonly talked about is the fact that 95% of the school act like IRL twitter SJWs. So, if you happen to make a joke that can be even remotely close to offensive, be prepared to be insulted/shunned from the rest of the students.
Tim: Have you heard about Rosedale Heights School of the Arts?
John: Yeah, my trans sister goes there.
Tim: Oh, cool. By the way, can I get some kush?
John: Yeah, my trans sister sells it. Just go behind the school before lunch and she can hook you up.
Tim: Thanks man!
