In 1976, the franchise relocated to St. Catharines and played as the St. Catharines Fincups for the 1976-77 season, however, the club returned to Hamilton for the 1977-78 season. The club then relocated to Brantford and was renamed as the Brantford Alexanders for the 1978-79 season.

The Steelhawks would play the 1984-85 season out of Mountain Arena while their new arena, Copps Coliseum, was being constructed and would not open until the 1985-86 season. The team remained in the Emms Division.

Windsor Spitfires to Windsor Compuware Spitfires
The Windsor Spitfires were bought by Peter Karmanos, the founder and CEO of Compuware in 1984 and were renamed as the Windsor Compuware Spitfires beginning in the 1984-85 season.

Tragedy
On January 4, 1985, Bruce Melanson of the Oshawa Generals collapsed at practice and died from a heart ailment known as Wolff-Parkinson-White syndrome which resulted in him having a rapid heartbeat because of electrical impulses in the heart taking extra pathways. He was 18 years old at the time of the incident. Melanson was a second round draft pick of the New York Islanders at the 1984 NHL Entry Draft.

The Generals wore black arm bands for the remainder of the season in memoriam of their teammate. In his memory, the club no longer issues the uniform number "9". A memorial scholarship was also set up at his former high school in New Brunswick.
