My friends and I did - 13 Sedah Ave.
Sadly, this was the worst escape room that I've ever done. Nothing scary about it, no storyline and puzzles that didn't make sense. The "physical challenge" was also very strange as a house wouldn't have such a contraption to have to navigate. It was as if the creators just ran out of ideas and put something random in the house to try and make the game longer. There was no suspense or fear factor in the game at all.
This is not my first escape room, so obviously I'm comparing it to others. However there were others in my room for which this was their first escape room and they were really disappointed.
If you want a truly scary/intense escape room in Toronto, I would suggest The Unknown at Escape Games. That was the BEST escape room I've ever done and the creepy factor is high, the puzzles make sense and you're completely immersed in the experience.
