Famous teams from the TBAHA included: Fort William Beavers, Port Arthur Bearcats, Thunder Bay Twins, Fort Frances Royals, Kenora Intermediate Thistles, Kenora Junior Thistles, Kenora Muskies, Fort William Canadians, Westfort Hurricanes, Port Arthur Marrs, Thunder Bay Bombers and Thunder Bay Flyers.

The Kenora Thistles suspended operations in January 2016.

The senior league champion played the southern Ontario Allan Cup Hockey league for the Renwick Cup.
