According to the post, TTC streetcars can be rented out for full-on parties. Under "Chartering TTC Vehicles," all the details you need on renting a car for your squad can be found. The passenger capacity was pretty surprising to me, with the TTC allowing 70 seats and 181 standing, with a maximum of 251 people. As per the TTC, a TTC supervisor may need to be assigned and is "mandatory for all film shoots, bar crawls or what TTC deems necessary." The Reddit user who shared this wonderful information also shared a video from their TTC party streetcar experience, and I've gotta say, it looks like an amazing time.
