What we do
The Ontario Chapter of the International Society of Arboriculture, also known as ISA Ontario, is a component chapter of the larger international body. 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 just over 1000 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 1500 ISA Certified Arborists in Ontario and more than 30,000 worldwide.
We are involved in many major projects throughout the province relating to best industry practices, arborist education and training, and public education and awareness. Our membership is diverse; from commercial, municipal and utility arborists to educators, students, landscape contractors, landscape architects and grounds managers. This diversity in our foundation contributes to the strength of ISA Ontario. Central to all of this stands the tree, the focal point of our membership.
