Desharnais, whose scoring drought even attracted the attention of Montreal's new mayor, perched in front of the net to redirect Josh Gorges' drive in the first period. The goal stood after a video review to determine whether Desharnais had scored with a high stick.
Travis Moen also scored his first of the season, and Daniel Briere added a goal for the Canadiens, who have won two straight.
Ovechkin scored on a last first-period power play and again in the third period to give him an NHL-leading 19 goals.
When we started our journey we made a commitment to our fans to be relevant and to see the Chicago Blackhawks become the best professional hockey organization. There are not two finer symbols of that than Jonathan Toews and Patrick Kane. The commitment we have made to these incredible young men is equal to the commitment they have made to our team, our fans, our entire organization and the city of Chicago.
