WOAA Senior AA Hockey League  The WOAA Senior AA Hockey League is a Canadian senior ice hockey league governed by the Western Ontario Athletic Association. The league operates in Southwestern Ontario. The league uses Hockey Canada playing rules but is not operated under the jurisdictions of the Ontario Hockey Association or Hockey Canada. The league is based in the Georgian Triangle and Southwestern Ontario. The league has been in existence since 1943, one year after the WOAA itself was established, and has entertained large crowds with local former Junior Hockey players and the odd former professional player. The league is rather large and features teams of both Senior "AA" and Senior "A" calibre. It is generally accepted that none of these teams could financially compete with the Senior "AAA" teams that compete for the Allan Cup. The league is divided into two division that do not interlock until the playoffs. The WOAA consists of 17 teams, compared to the next biggest Ontario league, Major League Hockey, which has 5. From 1969 until 1977, the WOAA's premier division was an Intermediate B hockey league. Teams that were involved were the Mount Forest Rams, Arthur Tigers, Thornbury, Harriston Blues, Milverton Four Wheel Drives, Plattsville Combines, Seaforth, Durham 72's, Listowel, Lucknow, Crediton, Atwood, Ripley, Belgrave, and Kurtzville. The league was divided into as many as five divisions, Int. B, Major and Minor Int. C, and Major and Minor Int. D. The teams from the Major Int. C loop dominated the WOAA in terms of Grand Championships, winning 5 of 8. The most dominant teams were Mount Forest and Milverton. From 1977 until 1991, the WOAA promoted itself to the Intermediate A level. With four major loops: A, B, C, and D; the WOAA had a wide variety of teams, including the Durham 72's, Arthur Tigers, Brussels Crusaders, Lion's Head Northstars, Woodford Royals, Ripley Roosters, Drayton Comets, St. Clements Saints, Teeswater Falcons, Lucknow Lancers, Kincardine Kings, Dundalk Flyers, Monkton Wildcats, Mitchell Red Devils, and Tara Cyclones. As the league grew, they bought many smaller local senior leagues like the Central Ontario Hockey League, Central Grey-Bruce Hockey League and the Bruce Rural Hockey League, integrating many of their teams. In 1991, they came to grip with the times and dropped the Intermediate moniker, relabeling itself the WOAA Senior A Hockey League.
