The Junior "B" Northmen were formed in 2001. The Northmen are the farm team for the Junior "A" Orangeville Northmen.
Since their first season, the Northmen have done quite well, failing to reach the playoffs only once. In the 2006 Playoffs they made the finals. Both the Northmen and their finals opponent, the Oakville Buzz, were founded in 2001. To make the finals, Orangeville beat the Wallaceburg Red Devils 3 games to 0, the St. Catharines Spartans 3 games to 1, and the Niagara Thunderhawks 3 games to 2. The Buzz dispatched the Northmen 3 games to 1 and ended up defeating the Windsor AKO Fratmen in the one-game final for the Founders Cup, 10-4 to win the National Junior "B" title.
