Your Tree Healthcare Providers

Meet our Team

Established in 2012, Columbia Professional Arborists is a professionally trained urban forestry service with offices in Toronto, Ontario. Backed by a dedicated team of fully licensed, insured and bonded Arborists, we offer a wide range of services for residential & commercial clients throughout the G.T.A. We also provide 24-hour emergency service for storm damage repairs.

When you work with us, your trees will be looked after as safely as possible, with sound arboriculture techniques and practices. Our staff are qualified through the Ontario College of Trades and certified through the International Society of Arboriculture (ISA). They also take part in yearly Arborists Proficiency Training through the Infrastructure Health & Safety Association (IHSA).

We’ll give you trustworthy advice so you can make informed decisions about the trees on your property. With our help, your trees and canopies can be maintained healthily for years to come. Or they can be removed safely and worry-free. We’ll give you the recommendations you need. You can take it from there.

The guys were great and we are so happy to have the work done.
