The Northern Ontario Secondary Schools Athletics (NOSSA) is the governing body for all secondary-school athletic competition in Greater Sudbury, North Bay, Sault Ste. Marie and the North Shore.
The NOSSA mandate is to establish a closer relationship among the member schools of the Association[1] and to encourage and promote sound interscholastic athletic competition among the students of the secondary schools of the member districts.[1]
NOSSA champions typically represent the region of northeastern Ontario in Ontario Federation of School Athletic Associations (OFSAA) competitions.
The first NOSSA Championship was in 1923, when North Bay Collegiate was crowned NOSSA football champions.[2]
