Mark Streit’s second stint with the Montreal Canadiens could wind up being shorter than anyone might have anticipated. Sportsnet has learned that the Canadiens are actively shopping the 39-year-old defenceman, whom they signed to a one-year, $700,000-contract in July with $300,000 in potential performance bonuses. Streit scored six goals and added 16 assists in 68 games split between the Philadelphia Flyers and Pittsburgh Penguins last season. But he’s only appeared in two of Montreal’s four games this year while averaging 14:33 per game. Canadiens general manager Marc Bergevin said at the team’s annual golf tournament in September that the left-handed defender was brought to Montreal to potentially supplant what the team lost on the power play when Andrei Markov signed with the KHL’s Ak-Bars Kazan in July.
