A born leader, Jack Carroll displayed his exceptional talents in every position he occupied. While serving as agricultural representative in Peel he realized the possibilities of Alfalfa and vigorously promoted its production for both forage and seed. Soon that county became recognized as the Alfalfa centre for Ontario. At his instigation, the Peel Seed and Feed Co-Op was formed, primarily to merchandize Alfalfa seed, but later to service the farming community.

Promoted to Agricultural Headquarters at Queen’s Park in 1924, he served in many capacities – first as assistant director of the Agricultural Representatives Branch, later as director, Crops, Co-operation and Markets Branch, followed by director, Agricultural and Horticultural Societies Branch and finally as Assistant Deputy Minister of Agriculture.

He will long be remembered for his association with plowing matches. Aside from directing the activities of the provincial match, he played a leading role in organizing the Canadian Plowing Council, and eventually, the World Plowman’s Association. In recognition of his efforts he was elected the first president of the world organization and presided over the first world match, which was held near Cobourg, Ontario in 1953.

Jack Carroll took an active part in the affairs of many organizations in his hometown of Brampton, particularly the hospital board, the Chamber of Commerce and the Planning Board. Of him it can be said that he was one of those rare, public-spirited individuals, who throughout his lifetime, gave unstintingly of his talents in the service of his community and his country.
