As far as clubs go in Toronto, in my opinion they are shit! I guess your best options are 1. Turbo Nightclub on a Friday night. On one floor they play tech/house.Other floor- drum n bass.
Or System Soundbar is also an okay place to chill on a Friday.
On Saturday night all the clubbers go to Guverment which is alright-mainly progressive, little bit of trance. But i'm telling you, if your into trance forget the clubs in toronto, there just not worth wasting your time and money on.

You should definately hit this party(rave) on Sat June 30, called the Tao of Purple Heaven. It is being thrown by the most genuine production crew in the T-dot. They're known for siick trance parties. If need more info, check out the thread under the toronto scene.
