Ottawa 67's (OHL) acquired rights to Courchaine from Barrie Colts in January 2007
Invited to Boston Bruins 2007 training camp; signed three-year contract with Bruins in Sept 2007
2007-08: Played his rookie season with Ottawa and made the majority of starts. He earned two shutouts; one on December 16th vs. Mississauga, and the other on December 30th vs. Erie. He joined the Providence Bruins (AHL) on an ATO following the close of the season.
2008-09: The early-season groin injury that kept Courchaine from Bruins camp also kept him from securing the starting goalie role this season. He started 17 fewer games than he did last year and saw his save percentage drop below .900. Consistency was a struggle, especially during February when he went 1-3 in six appearances with a 5.49 goals-against average and .841 save percentage. At times, his butterfly style revealed a tendency to go down early and get beat high. At other times, he was prone to giving up dangerous rebounds. He managed to finish the season with a 13-11-2 record and 3.28 goals against average. Confidence and consistency were better throughout the playoffs. He finished 2-2-1 with a 3.00 goals against average and a .920 save percentage that included one shutout. Ottawa lost to Niagara Falls in overtime of game 7 for a first-round defeat, despite 45 saves from Courchaine.
2009-10: Courchaine split time between two OHL clubs this season, playing for the Sarnia Sting and Erie Otters. In 27 games for the Sting, Courchaine compiled a record of 8-16-1-1 while posting a 3.51 goals-against average and a .899 save percentage. Courchaine was traded to the Otters, where he played in 21 games. His record with that club was 12-8-0-0, with a 2.90 goals-against average and a .913 save percentage. Courchaine was on the losing end of 2 playoff contests, where he registered a 4.50 goals-against average and a .886 save percentage.
2010-11: Courchaine spent his first season in pro hockey with the Kelly Cup champion Alaska Aces backing up one-time Lightning product Gerald Coleman. In 28 games with the Aces, Courchaine was 17-7 with 2 overtime losses and 4 shutouts in 28 games. He posted an impressive 2.39 GAA and .907 save percentage for the Aces. Courchaine appeared in one playoff game for the Aces and stopped 35 of 37 shots to get the win. The successful season erased any memory of his forgettable ECHL debut – an October game with the Reading Royals in which he allowed 4 goals on 9 shots in seven minutes of action against Trenton; his lone appearance for the Royals.
A butterfly style goaltender, Courchaine stays square with the shooter and is quick to react. He has the ability to remain calm and focused during tough games, even when he is bombarded with shots. More often than not, he will come up with the big save.
Helped Alaska win a championship last season, but will still have a hard time making the Providence squad. Expect him to play for Reading of the ECHL this season.
