Subban, who turned 24 on Monday, will extend his season after Montreal was eliminated in five games in the first round of the playoffs last week against Ottawa.
Subban led all NHL defencemen in the regular season in points despite missing six games at the beginning of the season due to a contract holdout. He finished with 11 goals and 27 assists, and led all blue-liners with 26 power-play points.
As a result, the Toronto native was named a finalist for the Norris Trophy as top NHL defenceman. The winner will be announced in June.
Subban twice represented Canada at the world junior tournament, with the team winning gold on each occasion.
Subban is expected to be available when Canada takes part in a quarter-final game on Thursday.
Canada was in action Monday in a preliminary round game against Slovenia.
