If you’ve ever searched for a “licensed arborist” in Toronto, you’re not alone. Many homeowners assume tree care is a regulated trade, like plumbing or electrical work. The truth? Unlike electricians or plumbers, Ontario doesn’t license arborists.  

You don’t need a government-issued credential which means anyone can claim the title, regardless of skill or training.

How do you separate true professionals from unqualified workers? Understanding certification is the key.

Are Arborists Licensed in Ontario?

No. Unlike electricians or contractors, arborists in Ontario aren’t required to hold a provincial license. Instead, their qualifications come from professional certifications and hands-on training.

What “Certified Arborist” Actually Means

A trained, knowledgeable arborist will hold at least one of these recognized credentials:

  • ISA Certified Arborist® – A globally recognized certification proving expertise in tree biology, general tree care and tree practices.
    • Requires 3 years experience in any field related to tree care, including gardening or landscaping and completion of an exam.
  • Ontario Journeyperson Certification – A 6,000-hour apprenticeship leading to provincial trade certification.
    • Requires graduating from a formal post-secondary college program in Arboriculture in Ontario, usually Humber College or Fleming College.
    • Requires formal, documented on-the-job apprenticeship training from a registered employer and a certifying exam delivered by Skilled Trades Ontario.

Why This Confuses Homeowners

The term “licensed arborist” sounds official, so it’s easy to assume it means someone has proper credentials. Unfortunately, some untrained workers use this misunderstanding to market themselves as professionals—without the skills to back it up.

How to Spot an Unqualified Arborist

Not all tree workers have the training or insurance to do the job safely. Here are a few warning signs:

🚩 They call themselves a “licensed arborist” or say they are an “ISA Certified Company” or “Government Authorized”. (These things don’t exist).
🚩 They can’t provide proof ISA certification or trade credentials to back up claims.
🚩 They don’t provide services that require a certification, like arborist reports for tree permits.
🚩 They are vague on the details of the work they’re proposing to do, or don’t provide a written estimate. (A professional provides a written quote.)
🚩 They lack liability insurance or WSIB coverage.

Tree work is dangerous. Hiring an unqualified worker could lead to property damage, injuries, or fines if you violate City of Toronto Bylaws.
