For their 2021–22 season, the
National Basketball League of Canada (NBLC) announced that they had agreed to
interleague play with several teams from
The Basketball League (TBL). On June 18, 2022, the NBLC announced that
Dave Magley, president of TBL, would work alongside NBLC commissioner Audley Stephenson in overseeing the growth of both leagues. After the dissolution of NBLC following their 2022–23 season,
Dave Magley announced the formation of the Basketball Super League (BSL) to begin play in December 2023. BSL teams have no
salary cap and play in venues with a minimum capacity of 2,500, unlike TBL teams which have a salary cap and play in smaller venues. In April 2023, the
Newfoundland Rogues of the TBL were announced as the first BSL franchise. The
KW Titans,
London Lightning and
Sudbury Five of the defunct NBLC joined in May 2023. The
Windsor Express, another former NBLC franchise, announced in August 2023 that they would also join the league.
Montréal Toundra, formerly of the TBL, rounded out the inaugural 2023–24 BSL season's six teams. BSL's six teams engaged in
interleague play with TBL franchises in addition to their intraleague games, and the top four teams were awarded a playoff berth. Devin Kinsella was appointed as the league's first commissioner in August 2024. American teams from TBL joined the BSL for its 2024–25 season, including the
Glass City Wranglers,
Jamestown Jackals, and
Pontiac Pharaohs. The
Montréal Toundra announced it was taking a hiatus from the league in November 2024. The
Saginaw Soul were announced as an expansion franchise for the 2025–26 season in April 2025, but announced in September 2025 they will delay joining the league until 2026. In early October 2025, the
London Lightning announced that they will not be participating in the 2025-26 season. ==Teams==
