OK guys maybe they'll make this a sticky. Post any and all Info about canadian tournaments in this section.
For now I think the big one is SkyBall and that info is pretty easily found.
There's also a 3 Man at the old Tombstone Paintball field in montreal in mid January. First place takes $3000. Last years tournament was fairly decent and saw the likes of the All A's, Farside and others. You can find info about it at www.arnoldspaintball.com
