The Oro-Medonte 77's were a Junior ice hockey team based out of Oro-Medonte, Ontario, Canada. Their arena was in the community of Guthrie, Ontario. They played in the Greater Metro Junior 'A' Hockey League.
In April 2008, it was announced that Oro-Medonte had received its first junior hockey club since 1992. In May it was announced that the club would be known as the Oro-Medonte 77's. 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. http://www.officialgamepuck.com/TownIndex/Canadian/OntarioTowns/Oro77s.htm
