Despite not getting their first shot on net until seven minutes into the game, the Leafs finished the first period with a 1-0 lead on MacArthur's power-play goal.
Ten seconds after Ladd was put in the penalty box for high-sticking, Phaneuf made a pass to fellow blue-liner Carl Gunnarsson. Gunnarsson then sent the puck across the crease to MacArthur, who caught Pavelec out of position at 13:59 for his 11th goal of the season.
The Jets outshot the Leafs 15-8 in the opening period and 13-4 in the second.
Winnipeg jumped out to a 2-1 lead early in the second on goals by Bogosian and Ladd.
Bogosian got things going when he scored on the power play at 2:51. Then just 4 seconds after a Toronto penalty expired, Ladd tapped in a Kyle Wellwood pass from behind the net to make it 2-1 at 5:26.
Toronto's top sniper quickly made it 2-2 when Pavelec couldn't grab Kessel's shot with his outstretched glove at 7:07. It was Kessel's 21st of the season.
Wheeler broke the tie on a power play at 10:50, when a screened Reimer couldn't make the stop.
The Leafs doubled their shots on goal in the third period, but Pavelec held the line in his 32nd start of the season.
The Jets, who only play four games at home in January, hit the road for a four-game road trip that starts Wednesday in Montreal.
The Leafs host their next four games, beginning with Tampa Bay on Tuesday and Winnipeg on Thursday.
