Catholic Memorial has hosted a Christmas hockey tournament since 2017. The tournament has attracted teams from out of state including schools from Connecticut, New Jersey, and Colorado.
The tournament is traditionally a four-team, two-day tournament. The exception to this was 2019 when a six-team, three-day event was held and the champion was decided by standings rather than a playoff-style bracket.
The tournament is held at the Boston Bruins' practice facility - Warrior Ice Arena at the New Balance Building in Brighton.
