2009-10: Maxime Lagace played midget AAA hockey in Quebec with the Seminaire St-Francois Blizzard. Playing for the top team in the Quebec league, he split the goaltending duties with Sebastien Auger and in 22 games was 18-3 with a 1.86 goals against and .930 save percentage. In two playoff games he was 1-1 with a 3.55 goals against and .857 save percentage. Lagace was drafted by Prince Edward Island in the second round (20th overall) of the 2010 QMJHL Entry Draft.
2010-11: Lagace played in 18 games for the PEI Rocket as a backup to QMJHL veteran Evan Moshner in his first season of major junior hockey. He was 8-4 with 1 shutout and had a 3.59 goals against and .884 save percentage. The Rocket made the playoffs after finishing fourth in the Maritimes Division. Mosher started all five games in the playoffs.
2011-12: Lagace took over as the starter for the PEI Rocket in his second season; playing in 56 games. The Rocket had the QMJHL’s worst record, winning just 19 games, and Lagace was 12-39 with 5 overtime losses and 1 shutout – finishing with a 4.51 goals against and .867 save percentage. Lagace attended Dallas’ prospect camp and was signed to a three-year entry-level contract in July, 2012.
2012-13: Lagace’s season started with promise when he was one of three goalies named to Canada’s U20 team for the Canada-Russia Challenge in August. Lagace made his only start for Canada in Game 2 in Yaroslavl, stopping 20 of 26 shots in a 6-3 loss. He returned to Prince Edward Island for his third season with the Rocket. PEI was one of the QMJHL’s most improved teams, finishing third in the Maritimes Division, but Lagace struggled at times and was backing up 19-year-old Antoine Bibeau (Toronto) in the playoffs. Lagace was 13-12-1 with 1 shutout in 33 games and had a 4.05 goals against and .869 save percentage. He appeared in one playoff game in the series with Val d’Or, stopping 7 of 8 shots in 27 minutes of action.
2013-14: Lagace attended Dallas Stars training camp, suffering a mild concussion, before being sent back to the QMJHL as a 20-year-old. He skated for three different teams in his overage season. Obtained by Cape Breton in a June 2013 trade, he skated in eight games with the Screaming Eagles and was 3-3-1 with a 3.23 goals against and .887 save percentage. In November he was obtained by Shawinigan in exchange for a 2015 draft pick. He started three games, including a 32-save shutout against his former team, Charlottetown (a 2-0 win) and was 1-2 with a 4.00 goals against and .890 save percentage. Acquired by Sherbrooke at the trade deadline in January, he made 15 appearances for the Phoenix and was 2-9-3 with a 4.06 goals against and .887 save percentage. Sherbrooke had the league’s worst record and finished last in the West Division; one of two teams to miss the playoffs.
Lagace is a butterfly goalie with decent size and reflexes. He has a strong glove hand and uses his stick well along the ice but still needs to improve and refine his movement in the crease. Lagace has good pads and can stop a lot of shots down-low. He is fairly compact and can be prone to allowing high shots. Rebound control is a concern as it is with most young goalies. He faced a lot of shots in junior hockey and displayed a cool demeanor, learning quickly not to get down on himself for giving up goals.
Lagace attended training camp with the Stars before being assigned to AHL affiliate Texas to start the 2014-15 season and subsequently sent to the Idaho Steelheads. He was briefly recalled by Texas as an emergency backup he stopped 9 of 10 shots in relief of starter Jack Campbell. Subsequently loaned to the ECHL's Missouri Mavericks he has seen his first steady action of the season. Signed by the previous regime in Dallas, Lagace faces a steep climb up the ranks to one day reach the NHL. His play with the Mavericks has been encouraging but he needs to get more ice time before his long-term potential can be fairly assessed.
