Montreal is all about the night life. Lots to do in july. There the just for laughs, the jazz fest with lots of free concerts. If your driving once your get onto the island, there speed camera and no turning right on red, also no talking on the cell, there usual on off ramp or using video camera & radar on over pass to get people.
Also july is destruction season in montreal. So lots of road work. If going down town park around atwater, lionel groulx metro, free parking there in the restidental section, just watch out for local parking spot for people who life there. since it isn't always clearly marked on the signs. You can walk to downtown from there or take the metro with a visiter pass.
