Who We Are & What We Do

THE INTERNATIONAL SOCIETY OF ARBORICULTURE (ISA) enjoys a rich heritage as a scientific and educational organization with a primary mission to disseminate information and knowledge in the care and preservation of trees. The Ontario Chapter sits consistently at 800-900 members, while the international membership is over 22,000, divided into almost 50 chapters and associate organizations worldwide – the world's largest such organization. There are currently over 1300 ISA Certified Arborists in Ontario and more than 31,000 worldwide.

We are involved in many major projects and legislative initiatives throughout the province relating to best industry practices, arborist education and training, and public education and awareness. Our membership is diverse, from commercial, municipal, educators, students and utility arborists to landscape contractors, landscape architects and grounds managers. With this diversity comes different and sometimes conflicting points of view, all of which contribute to the strength of ISA Ontario. Central to all of this stands the tree, the focal point of our membership.
