The Langley Junior Thunder compete in the eight-team BC Junior A Lacrosse League (BCJALL) which is for players ages 16 to 21 and features future and current NCAA and professional players.
The Thunder joined the BCJALL in 2009 and in that time have had individual players win five league awards – Brett Dobray won the Most Sportsmanlike Award in 2012; Ryan Martel won both the Marcolis Gibson Award for Rookie of the Year in 2017 as well as the Bob Reid Memorial Award for Outstanding Achievement in 2019, and in 2022, Matt Abbott won the Al Boles Award for Most Inspirational Player while Kyle Brunsch was the recipient of the John Urban Award for Graduating Player. 2022 also saw the Thunder coaching staff -- head coach Adam Smith, assistant coaches Kevin Reid, Connor Frost and Keiffer Widen and goalie coach Kyle Mooney -- receive the Doug Hazelwood Memorial Trophy for Coach of the Year.
Langley has also had seven players drafted into the National Lacrosse League with Dobray a third-round selection (26th overall) of the Vancouver Stealth in 2013 while Martel and Anthony Kalinich were each taken by the Calgary Roughnecks in 2017. Martel was selected in the first round, 11th overall, while Kalinich was second-round pick, 21st overall. The 2022 edition of the Thunder team saw four players drafted by NLL teams: Isaac Ngyou (second round, 40th overall) to the  Saskatchewan Rush, Drew Kask to the Vancouver Warriors (fifth round, 85th overall), Stryker Roloff (sixth round, 91st overall) to the Las Vegas Desert Dogs, and Kaden Doughty (sixth round, 99th overall) to Calgary.
