MONTREAL -- Brendan Gallagher and Jacob De La Rose each scored twice as the Montreal Canadiens emphatically beat the Ottawa Senators 9-2 on Saturday in the last pre-season game for both teams.

Alex Galchenyuk, Andrew Shaw, Shea Weber, Max Pacioretty and Victor Mete scored for the Canadiens (2-6-0), which ended their pre-season on a high note after dropping their first six games. Jonathan Drouin had three assists.

Kyle Turris scored in the game's first minute for the Senators (3-3-0) and Mark Stone added another in the third.

Montreal outshot Ottawa 40-17.

After Turris scored the opener 22 seconds into the game on the power play for the Senators, Gallagher put away the equalizer at 11:04 by poking a loose puck from his knees between Craig Anderson's pads.

The Canadiens then scored twice in 26 seconds at the end of the first period to take a 3-1 lead into the intermission.

Galchenyuk got the first with 34 seconds left in the period as he fired a wrist shot into the roof of the net. Shaw, with a tip-in right in front of goal, with eight seconds on the clock.

Weber added a fourth for Montreal with a slap shot from the point on a 5-on-3 power play at 1:24 of the second period.

The Canadiens scored five times in the third.

Gallagher got his second of the game at 2:11 and Pacioretty added another 18 seconds later. The Canadiens captain finished with one goal and two assists.

Stone got one back for the visitors at 5:46 before De La Rose put an end to the improbable comeback less than two minutes later. The 22-year-old added his second with a wrist shot at 10:04.

Defenceman Mete, with his first in a Canadiens uniform, beat backup goalie Mike Condon at 13:43 on the power play.

Ottawa took eight minor penalties in the game to Montreal's seven.

Both teams open their regular seasons on Thursday. Ottawa hosts the Washington Capitals while Montreal faces the Sabres in Buffalo.
