The Brooklin Agricultural Society is a Not for Profit volunteer organization which operates and organizes the annual Brooklin Spring Fair. The Brooklin Spring Fair celebrated its 100th Anniversary in June 2011.

The Fair supports many organizations in the community such as; the Order of Oddfellows Lodge in Brooklin, Ontario Volunteer Emergency Rescue Team (O.V.E.R.T), Brooklin Community Centre & Library, Kedron Boy Scouts and Brooklin Boy Scouts and Brooklin Redmen. We also present an annual achievement award to a graduating student at each of the elementary schools in Brooklin.
