Kyle Turris scored 34 seconds into overtime to lift the Ottawa Senators to a 2-1 victory over the Montreal Canadiens on Tuesday night.

Turris, with his eighth goal of the season, finished a two on one with Mike Hoffman after a turnover in the Montreal end. It was the Canadiens' first experience with the new 3-on-3 overtime format.

Jean-Gabriel Pageau also scored for Ottawa (6-4-2), while Dale Weise tallied for Montreal (11-2-1).

The Canadiens outshot Ottawa 36-26 in regulation time and 36-27 overall.

Mike Condon, filling in for injured Carey Price for a third straight game, made a spectacular glove save near the end of a scoreless first period to prevent Cody Ceci from finishing a two on one with Pageau.

Pageau opened the scoring shorthanded 3:16 into the second frame. After P.K. Subban fanned on a point shot, the stocky Senator went in on a breakaway and beat Condon between the pads.

It was the Gatineau, Que. native's fourth goal and sixth point in eight career games against the Canadiens, including a near-identical short-handed goal in Montreal's win in Ottawa on Oct. 11. He also had a hat-trick against them in the 2013 playoffs.

Weise tied it on a power play at 6:13, completing a tic-tac-toe play with Andrei Markov and Alex Galchenyuk. It was Weise's seventh goal, three short of his career high set last season and tying Max Pacioretty for the team lead.

Two goals were nullified after video review -- a Tomas Plekanec tally in the first because Brendan Gallagher interfered with goaltender Craig Anderson and an Alex Chiasson effort in the third due to a quick whistle.

Ottawa's Mark Stone served the first of his two-game suspension. His spot on the top line was take by Curtis Lazar.

Notes: Montreal sent defenceman Greg Pateryn to AHL St. John's for a conditioning stint. Although healthy, Pateryn has yet to get in a game this season.
