The 25-year-old right wing had three goals and four points in 17 regular-season games with the Canadiens after being acquired from the Vancouver Canucks on Feb. 3. He had seven points in 16 Stanley Cup Playoff games. Of his three playoff goals, two were game-winners.
"The acquisition of Dale Weise contributed to the success of our team this season," Canadiens general manager Marc Bergevin said. "A young veteran with a lot of character, Dale is an intense player with a strong work ethic. We're very pleased to have him as part of our team moving forward."
Weise set career-bests with six goals and 16 points in 61 regular-season games this season. A 2008 fourth-round pick (No. 111) of the New York Rangers, Weise has 13 goals and 30 points in 179 games with the Rangers, Canucks and Canadiens.
It appears defenseman Douglas Murray will be leaving. According to a report in La Presse, the Canadiens likely will not offer Murray a contract, allowing him to become an unrestricted free agent July 1.
Murray, 34, had two assists and a minus-12 rating in 53 regular-season games and got into three playoff games, all in the second round against the Boston Bruins.
