Ottawa's mature canopy is a point of civic pride, but ice storms, the 2022 derecho and a strict Tree Protection By-law mean homeowners often need an arborist who can handle both emergencies and paperwork. Of the 17 tree-care companies listed in Ottawa on treelist.ca, these three pair ISA-certified skill with the local knowledge to navigate the city's permit process.
Green Thumb Tree Specialists was founded in 2018 by Riley, an ISA Certified Arborist with Arboriculture Canada training and more than a decade in the trade. He started the company after growing frustrated with how big outfits treated homeowners, unclear pricing, property damage and poor communication, and built Green Thumb as the deliberate opposite. Services span pruning, trimming, emergency response, tree and stump removal, and even snow removal.
Riley has personally managed over 120 emergency removals during the region's worst ice storms and handles every complex permit application through the city's Tree Protection By-law himself. The company is fully licensed and insured with WSIB coverage on every job.
Above Average Tree Removal & Hedge Trimming brings over 25 years of experience to Ottawa and Orleans, under owner Mike White, an ISA Certified Arborist. The company focuses on tree removal, pruning and hedge trimming, and takes care of the debris and brush cleanup that often gets left behind.
An arborist visits in person to provide estimates, so you get a knowledgeable assessment rather than a number over the phone.
Arbor-All Tree Services is a well-established, ISA Certified and BBB-accredited company with more than 20 years of experience. Based in Rockland, it serves a wide eastern-Ontario territory stretching from Kanata and Stittsville all the way to Hawkesbury, making it a practical option for homeowners in Ottawa's outer suburbs and beyond.
The company is fully insured and covers the standard range of residential tree care.
Final Thoughts
For storm response and permit-heavy jobs in the core, Green Thumb's hands-on, by-the-book approach stands out. Above Average offers 25-plus years of well-reviewed removal and hedge work across Ottawa and Orleans, while Arbor-All is the established pick for the eastern suburbs and rural edges. With any of them, confirm ISA certification and insurance, and ask about Ottawa's Tree Protection By-law before removing a mature tree.
