If you want to make new friends by the thousands and you don't mind chest-to-chest, sweaty crowds, The Guv is the place for you. At 22,000–square–feet, with eight different rooms, each with a different theme and music, it's Toronto's largest nightclub. Cutting-edge sound and lighting keep the crowds partying into the wee hours of the morning.  Note that you'll often get better prices when tickets are purchased in advance online.
