TIME: Tuesday, 7:30 p.m. EST.
Toronto was mired in a 0-for-25 slump with the man-advantage before ripping off four power-play goals in a 5-1 win over Ottawa on Saturday.
Gary Roberts paced the Maple Leafs with two power-play goals. Mats Sundin, Robert Reichel and Alex Ponikarovsky also scored for Toronto, which is first overall in the Eastern Conference with 69 points.
Saturday's game helped boost Toronto's power play to eighth in the NHL - 18.4 percent.
With the victory, Toronto coach Pat Quinn became just the fourth coach in NHL history to win 600 regular-season games, joining Scotty Bowman, Al Arbour and Dick Irvin. Toronto goaltender Ed Belfour also passed Tony Esposito for fourth on the wins list with his 424th.
Toronto forward Owen Nolan returned to the lineup for the first time in nearly a month after getting high-sticked in his left eye.
Nolan has had headaches and blurred vision since Buffalo's Jay McKee high-sticked him on Jan. 3. The veteran winger had laser surgery two days later and missed 12 games.
The Blackhawks are 2-19-0-1 on the road since Nov. 7, beating only Nashville 2-1 on Nov. 7 and Calgary 5-3 on Friday.
Chicago rallied late but fell short in a 6-4 road loss to Montreal on Sunday.
Sullivan, who had two goals, leads Chicago with 25 assists and 38 points.
