There are 51 county and regional federations of agriculture, providing local representation across Ontario.

Drew Spoelstra was elected as the new OFA President at the 2023 Annual General Meeting, held in Toronto, Ontario.

The PAC consists of 90 members providing grassroots input on issues and policy direction, including representation from each county and commodity organizations.

In January 27, 1936, representatives of Ontario’s farm groups held a meeting at the Royal York Hotel in Toronto in response to the creation of the Canadian Chamber of Agriculture in 1935, later renamed the Canadian Federation of Agriculture.

The new organization was created to establish a provincial brand, named the Ontario Agricultural Conference.
