The Central Ontario Junior C Hockey League was a junior ice hockey league in Ontario, Canada, sanctioned by the Ontario Hockey Association. The "Central" played inter-league games with the Empire Junior "C" League. The champion of the Central competed for the All-Ontario Championship and the Clarence Schmalz Cup. The league is now a division in the Provincial Junior Hockey League.

The Ontario Hockey Association (OHA) is the governing body for the majority of junior and senior level ice hockey teams in the province of Ontario. Founded in 1890, the OHA is sanctioned by the Ontario Hockey Federation along with the Northern Ontario Hockey Association. Other Ontario sanctioning bodies along with the OHF include the Hockey Eastern Ontario and Hockey Northwestern Ontario. The OHA controls three tiers of junior hockey; the "Tier 2 Junior "A", Junior "B", Junior "C", and one senior hockey league, Allan Cup Hockey.
