The IJHL shares its
name with a former league, which competed at the
Junior "A" level in the same region from 1973 to 1991. Since being founded in 1996, the IJHL has been strictly a Junior B League, one tier below the Junior A
Maritime Junior Hockey League and two tiers below the Junior ice hockey#Major Junior
Quebec Maritimes Junior Hockey League, which both have teams located in Prince Edward Island. In 2002, the
O'Leary Eagles won the
Don Johnson Cup as Maritime Junior B champions. Nine years later, in 2011, the
Kensington Vipers repeated the act as Maritime champions, following up their success again in 2013 and 2023 respectively. Following the 2021-22, the league lost both the
Western Red Wings and Eastern Maniacs but added the Kings County Rivermen. With only 3 remaining teams, the league negotiated to play regular season games with the
New Brunswick Junior B Hockey League (NBJHL), with PEI holding their own playoff series. For the 2023-24 season, the Sherwood Metros and Kings County Rivermen merged and, along with Kensington, will once again compete in the NBJHL to determine the PEI representative for the Don Johnson Memorial Cup. For the 2024-25 season the Sherwood Metros announced a one-year sabbatical, leaving only the Kensington Vipers representing PEI at the Junior B level. The 2025 Don Johnson Memorial Cup was initially scheduled to be hosted by the Kensington Vipers. However, the community did not want the championship which was re-located to Cognac New Brunswick. The Vipers did attend as the PEI representative. ==Teams for 2024-25 Season==
