The Cornwall Celtics joined the OLA-B in 2006 with the Hamilton Bengals. These two teams are just 2 more teams in a huge expansion of the OLA-B in recent years. Their first season was a good start for such a competitive level of play. They first game was a 15-7 loss to the Gloucester Griffins on April 22, 2006. On May 6, 2006, the Celtics picked up their first win against the Milton Mavericks, 6-5. The Celtics did not make the playoffs in their first season, but that is to be expected in such a large lacrosse league.
