Actually, RP, the answer is no. There are no clubs open in Montreal on Sunday night. Being theatrical in nature, they're also dark on Mondays. In fact, the nearest club to Montreal that will be open between now and Thanksgiving are in Minneapolis.
The good news is that there are busses leaving regularly. The MERB Foundation for buying Robertpal a One Way Ticket to Minneapolis is now open. I'm in for the first fiver.
