Montreal 2, Chicago Fire 0
Romell Quioto scored in the 60th minute, James Pantemis made four saves and Montreal blanked the Chicago Fire 2-0.
With the win, Montreal moved past Atlanta for fifth place in the Eastern Conference.
Djordje Milhalovic found Quioto in the box and he scored his fifth goal of the season off a hard strike.
Chicago had a goal nullified with an offside in the 77th minute and minutes later an own goal sealed the match when Mathieu Choiniere's cross went off defender Carlos Teran.
