This is a bit of last-minute, and is targeted at a niche but active and growing community in Montreal, those who are working in computer security.
MTLSec is organizing an informal get together at Vieux-Dublin this evening. You can talk about the latest hackfest in Quebec city which got the team Amish Security from ETS winning, or talk about SOPA, which is making rounds on the Internet today.

On another note, if you are feeling less knowledgeable in infosec, you can also go to the co-founders event today at notman house
