On July 6, 1980, the Degagne Buccaneers and Thunder Bay North Stars were informed by the TBAHA that they would not be permitted to field teams in the 1980–81 City League. On July 10, 1980, the executive of the Thunder Bay Kings was formed and gave life to the city's premier junior squad for the next twenty years. From 1980 until 1982, the Kings played in the Thunder Bay Hockey League with the Allan Cup-contending Senior "A" Thunder Bay Twins, the Hardy Cup-contending Intermediate "A" Thunder Bay Blazers, and the Canadian Interuniversity Athletics Union's Lakehead University Nor'westers. Their first season saw them finish in second and meet the Intermediate Blazers in the league semi-final, which the Kings won 3-games-to-2. In the finals, they were swept by the Senior Twins 4-games-to-none. In the second year, the Flyers finished in third and drew the Blazers again. They defeated the Intermediates 3-games-to-1, to meet Lakehead University in the final. Lakehead upset the Twins 3-games-to-1 in the other semi-final. The Kings won the final in seven games to win the City Championship. In 1982, the Thunder Bay Hockey League was disbanded. The Blazers folded into the Twins, who joined Manitoba's Central Senior A Hockey League. The Kings, the newly formed Thunder Bay Hornets and the Schreiber North Stars Junior "B" hockey teams, formed the Thunder Bay Junior Hockey League. The Kings won the league in 1983. In the 1983-84 season, the North Stars were replaced by the Jr. B Thunder Bay Maple Leafs. The Kings celebrated an 18-game perfect season before winning the city championship for the third straight year. In 1984, the Thunder Bay Junior Hockey League folded. The Kings changed their name to the Thunder Bay Flyers and jumped to the United States Hockey League. The Hornets and Maple Leafs merged under the Thunder Bay Hornets banner and jumped to the Manitoba Junior Hockey League. The Thunder Bay Junior Hockey League folded in 1984. Many former players made the jump to the Ontario Provincial Junior A Hockey League; some went to the then existing version of the Northern Ontario Junior Hockey League; and others to the Manitoba Junior Hockey League. However, due to Thunder Bay's location, the league was closer to Minnesota than the closest franchises in the other Ontario Junior "A" Leagues, and the Thunder Bay Flyers of the defunct Thunder Bay League survived by jumping the border to play in the top tier of American junior hockey, the United States Hockey League, and with some success. From 1984–85, when they entered the league, until their exit after the 1999-2000 season, the Flyers won four Anderson Cup regular-season titles in five years, and two straight Clark Cup playoff championships in 1988 and 1989. No team coached by Dave Siciliano, whose tenure extended from 1986 to 1993, finished lower than fourth or won fewer than 31 games in a 48-game season. Although competing in the USHL during the regular season, the Flyers also competed provincially for the Dudley Hewitt Cup against teams from the Ontario Provincial and Northern Ontario Junior Hockey Leagues, and the right to represent Ontario at the Centennial Cup for the national title as a result. They made their first appearance in the Centennial Cup by default in 1988, and four times as winners of the Dudley Hewett Cup: in 1989, 1991, 1992, and 1995. They have won the national championship twice: at the 1989 Centennial Cup competition, by defeating the Summerside Western Capitals, then of the Island Junior Hockey League, 4-1 in the final game; and at the 1992 Centennial Cup, by defeating the Halifax Mooseheads 8-1 in the semi-final, and the Winkler Flyers of the Manitoba Junior Hockey League 10-1 in the final. The Flyers played their last game in 2000. The end of the Flyers resulted in the creation of the Superior International Junior Hockey League in 2001 to continue the tradition of the old Thunder Bay Junior Hockey League as a purely local organization. The league has been successful since its founding with its top team being the Fort William North Stars. The departure of the Flyers also sparked the creation of the very successful Lakehead University Thunderwolves men's hockey program, playing in the Ontario Universities Athletics Conference of the CIS.
