Armia was dealt to Montreal from the Winnipeg Jets along with goaltender Steve Mason on June 30 in exchange for defensive prospect Simon Bourque. The Finnish native played in 79 regular-season games for the Jets last campaign, registering 12 goals and 17 assists in 12:36 of ice time per night.
The 25-year-old forward will bring some much-needed scoring depth to a Canadiens forward group that managed the third-lowest goal total last season with a measly 207.
Armia was drafted by the Buffalo Sabres in the first round (16th overall) of the 2011 NHL Draft. He has 26 goals and 58 points in 180 career regular-season games.
