The Limestone Umpire Association, or the LUA, is a localized softball umpire association that serves the Kingston, Ontario, Canada and surrounding regions. Founded in 2014, it began as a small group that covered a local men's fastball league. For the 2015 softball season, the group quadrupled in size and began covering two men's fastball leagues, 3 surrounding areas' minor fastball programs as well as area slo pitch tournaments.
