Ribfest and Poutinefest come to mind, but they're constantly shit on for being overpriced and not worth it. That's before we even get into the part about the organizer being pro-convoy.
I guess there's Bluesfest? Because Jazzfest is there but isn't nearly as popular.
Tulipfest... It's called that, sure, but it's iffy.
Glowfest - I think that's still happening. It's not huge but it's a known name.
Other than that, I don't think Ottawa does anything that's unique to just us.
... did... Did Ottawa give itself this nickname? 🥲
