Forwards Brandon Reid, Nathan Smith and defenceman Yannick Tremblay scored for the Moose in front of 3,964 fans at Ricoh Coliseum. Right winger Colby Genoway
collected two assists, while Reid added a helper for a two-point game.
Left winger Colin Murphy replied for the Marlies.
The game did not feature many scoring opportunities, but the Moose took control by jumping out to an early lead and preventing the Marlies from generating any quality chances.
The Moose, which moved into first place in the North Division with the victory at 32-17-11, have beaten the Marlies in all four meetings between the two teams this season. As well, Manitoba improved to 7-0-1 lifetime at Ricoh Coliseum. The clubs have four more games against each other this season, all in Winnipeg.
The Marlies fell to 23-30-6 with the loss, and need to quickly turn things around in the final seven weeks of the regular season if they hope to qualify for the playoffs. Toronto, with a 9-18-3 record at home this year, was 10 points out of a playoff spot entering last night's action.
Toronto goalie Justin Pogge made 17 saves on 20 shots. The Marlies rookie goalie had little chance on any of the Moose's goals, all of which came on deflections or cross-ice one-timers.
Manitoba, which had a nine-game winning streak snapped in a 3-0 loss at Syracuse on Saturday, was 0-for-6 on the power play. Toronto went 0-for-4 with the man advantage.
The Moose led 2-0 after the first period and 3-0 through 40 minutes.
Manitoba opened the scoring on a bang-bang play early in the first period, when Genoway centred pass from behind the net that Reid was able to chip over Pogge at 2:00. And Smith gave the Moose a 2-0 edge when he drove to the net and deflected Jason Jaffray's pass over Pogge's glove at 13:11. Manitoba also hit three goalposts in the opening frame as the visiting side carried the play.
Toronto had a chance to close the gap when Brett Englehardt was awarded a penalty shot late in the first period, after being hauled down, while on a breakaway by Moose defenceman Shaun Heshka. But the big Marlies left winger missed the net when he tried a backhand deke against MacIntyre.
The Moose went up 3-0 early in the second period when Tremblay one-timed Genoway's pass over Pogge's left shoulder at 1:17. To that point in the game, it was just the eighth shot on Pogge, who was coming off a shutout on Saturday (3-0 against Rochester).
Toronto got on the board early in the third period when Murphy scored from a bad angle at 1:23. The left winger picked up the puck in the left corner and slid a shot along
the goal line that found a hole between MacIntyre's leg and the goalpost.
The next action for both the Marlies and Moose is back-to-back games in Winnipeg on Friday and Saturday.
