The junior North Bay Trappers started operating in 1921-22 which was the third year of the Northern Ontario Hockey Association. They made a very big impact in their first seven years. They finished first in six of those years. The Trappers won the Northern Ontario title in 1923-24 and 1925-26. But in May, 1928 the town's arena burned down. The Northern Ontario Junior League was started up in 1962-63. The Trappers did very well, winning the league title in 1964, 1966 and 1968. But this league folded in 1972, after Sudbury and Sault Ste. Marie were accepted into the Ontario Hockey League.
