However, when the Boston Bruin Cubs dropped out after the 1935–36 season, the league was reduced to just four active teams (Philadelphia, Providence, Springfield, and New Haven).
At the same time, the Rust Belt-based International Hockey League had also been cut down to just four teams; Syracuse, Buffalo, Pittsburgh, and Cleveland.
With both leagues at the bare minimum number of teams to be viable, they decided to form a temporary "circuit of mutual convenience" known as the International-American Hockey League.
At a meeting held in New York City on June 28, 1938, the two leagues formally merged into a unified eight-team circuit operating under the IAHL name with the addition of the EAHL's then three-time defending champion Hershey Bears, which was awarded an IAHL franchise that day to replace the defunct Buffalo club.
The Abbotsford Canucks are descended from the Springfield Indians franchise, which moved to Worcester, Massachusetts, in 1994 before relocating to Peoria in 2005, to Utica in 2013, and to Abbotsford, British Columbia, in 2021.
