James van Riemsdyk and Dion Phaneuf scored for Toronto in a game tied 1-1 going into the final period. The Leafs almost tied it up in the dying seconds with a wild flurry and goalie James Reimer on the bench.
Reimer had 34 saves, while Robin Lehner made 26 stops for Ottawa.
The Senators outshot the Leafs 37-28.
The game was the first for Toronto since Sunday's brawl with Buffalo, which resulted in suspensions for the Maple Leafs' David Clarkson and Phil Kessel and a fine for Sabres coach Ron Rolston.
