Phaneuf, 28, is under contract through the 2020-21 NHL season. “Dion is our team leader and has been a pillar in our building process,” said GM Dave Nonis said in a statement released by the Leafs. “He has proven to be a very durable and reliable defenceman in all facets of the game. He plays big minutes in every situation for us and we’re pleased to have him under contract for the next seven seasons.” Phaneuf, 28, has played 39 games for the Leafs this season, and has 15 points (4 goals, 11 assists).
