Hoffman said Montembeault was the difference in the game, not only because of the number of shots he faced, but the quality of his saves.
"He kept us in it right from the first period all the way through some crucial stages of the game," Hoffman said. "Kept us alive and gave us a chance to win in overtime."
The Canadiens played the first of seven consecutive road games. Coach Martin St. Louis said there was an urgency to start the trip well following a 5-1 loss at home to the Tampa Bay Lightning on Saturday.
"I think they knew how much we needed to win," St. Louis said. "It wasn't perfect, but we found a way and hopefully it helps us get a little bit of a swagger back."
