The Thunder Bay Twins were formed in 1970 with the amalgamation of the Port Arthur Senior Bearcats and the Fort William Beavers. In their first 5 years of action, the Twins earned their way to one Eastern semi-final and two eastern finals. After only their fifth season of active competition, in 1974-75, the Thunder Bay Twins would go all the way to the top of the Canadian Senior Hockey Association by winning the Allan Cup.

That season the Twins first won the Western International Hockey League title before facing off against the Barrie Flyers in the Allan Cup finals. The series was split with three games being held in Barrie and three in Thunder Bay. In Barrie, the Twins lost two games and won one before returning home. In Thunder Bay, before their hometown fans, the Twins clinched the series with three straight decisive victories of 8-2, 5-2 and 8-4. The 1974-75 Twins had broken a 35-year silence of Allan Cup victories for Thunder Bay, as the last time the Cup was brought home to the Lakehead was in 1939 when the Port Arthur Seniors won the title. This victory was to be just the first of five, as the Twins went on to successfully win back the Allan Cup in 1984, 1985, 1988 and 1989.
