The Ontario Minor Hockey Association (OMHA) is a minor ice hockey governing body in Ontario. The OMHA is sanctioned by the Ontario Hockey Federation and Hockey Canada. The OMHA was founded on November 30, 1940, after a merger of the Ontario Juvenile Hockey Association and the Ontario Midget and Bantam Hockey Association, arranged by Jack Roxburgh. The new league began its first season with eight teams, and signed an affiliation agreement with the Ontario Hockey Association.
There are two "AAA" leagues, the Eastern AAA Hockey League and the South-Central Triple A Hockey League as well as four "AA" leagues in the York-Simcoe AA League, Tri-County AA League, Lakeshore League and the Bluewater League. The OMHA also has six "A" leagues in the Bluewater League, Niagara District League, Tri-County A League, York-Simcoe A League and the Lakeshore League.
The OMHA also has several representative leagues from the BB-E representative classifications such as the Shamrock League, Georgian Bay-Muskoka League, Southern Counties League, Western Ontario Athletic Association, Victoria Durham League and the Eastern Ontario League.
