Mikael Renberg and Gary Roberts scored for the Maple Leafs, who are still first in the Eastern Conference with 61 points despite winning just two of their last six games.
The Philadelphia Flyers, who lost Tuesday, are second with 59.
Belfour, rarely tested in the first two periods, recorded his 70th career shutout, three fewer that New Jersey's Martin Brodeur on the active list.
The Maple Leafs lost yet another player to injury when Darcy Tucker didn't return after New York's Jason Blake high-sticked him in the face near the end of the second period. Tucker went after Blake after initially dropping to the ice.

Nolan missed his eighth straight game after being high-sticked in the left eye on Jan. 3. He expects to return next Tuesday.
Blake didn't receive a penalty for high-sticking Tucker, yet six of the nine penalties called in the game were for high-sticking.
