The name pays homage to Oro's long hockey history, and the team's predecessor the Oro 77's who participated in the Georgian Bay Junior C Hockey League from 1977 until 1992. 
On September 15, 2008, the Oro-Medonte 77's played their first ever GMHL game, on the road, in Richmond Hill against the Ontario Lightning Rams. Oro emerged victorious, winning 8-6.
