Northern Ontario Curling Association
When it comes to curling in Canada, Northern Ontario is treated as if it were a province. It is the only sub-provincial region that sends teams to the various national championships. Only the Scotties Tournament of Hearts lacks a separate Northern Ontario team. Northern Ontario's separate entry exists due to historical precedent. Ever since the very first Brier has Northern Ontario been represented. The rest of Ontario is governed by the Ontario Curling Association.
The NOCA was founded in 2007 upon the amalgamation of the Northwestern Ontario Curling Association, Northern Ontario Ladies Curling Association, the former Northern Ontario Curling Association and Temiskaming & Northern Ontario Curling Association. Prior to 2007, the region as a whole was governed by the Northern Ontario Curling Federation.
