MONTREAL — The Montreal Canadiens shored up their defense, acquiring James Wisniewski from the Islanders for a pair of draft picks.

Wisniewski is scheduled to join the Canadiens on Wednesday in Tampa Bay.

The Islanders received Montreal’s second-round selection in 2011 and a conditional fifth-round pick in 2012 in the trade Tuesday.

The 26-year-old Wisniewski played in 32 of the Islanders’ 34 games this season. He was the team’s top-scoring defenseman with 21 points (three goals, 18 assists).

Wisniewski has 118 points (20-98) in 286 career NHL games with the Chicago Blackhawks, Anaheim Ducks and Islanders.
