Northern Senior A Hockey League

The Northern Senior A Hockey League was an Ontario Hockey Association-sanctioned senior loop in Southwestern Ontario. Its champions could compete for the Hardy Cup in the 1980s and briefly for the Allan Cup in the 1990s.

The league originated as the OHA Intermediate C Hockey League in the 1970s, became the Northern Intermediate B Hockey League in the 1980s and merged with the Central Senior B Hockey League in the late 1980s, before folding due to lack of interest in 1993. In 1986-87, the league, with a few other local teams turned into the Georgian Bay Senior A and Georgian Bay Senior B Leagues - this lasted for one season. Two teams from this league, the Elora Rocks and Shelburne Muskies, still actively exist in the WOAA Senior AA Hockey League.
