LEAF Score

Frequently Asked Questions

What is a LEAF Score, and how is it calculated?

See LEAF Score Explained for the full breakdown. Every company can earn up to 10 leaves, one for each of:

  • 50+ Google reviews (scaled down for arborist consultants)
  • 5+ years in business
  • Employing a Certified Arborist
  • Employing a Tree Risk Assessment Qualification holder
  • Employing a Board Certified Master Arborist
  • A certificate of insurance on file
  • Valid WSIB clearance
  • Transparent pricing
  • Verifying their own listing
  • Being founded in Canada
Can a company pay to rank higher?

No. Money will never buy position on this website. No matter how much a company spends on marketing, it cannot buy a higher score. A higher score can only be earned through education, experience and client satisfaction.

I know (insert name) is a (insert credential) with (insert company). Why doesn’t this show up in ArborProof’s records?

It is highly likely that this person has not updated their profile with the International Society of Arboriculture. Specifically, they MUST state in their profile the website for the company that they work for. It isn’t enough for them to be a credentialed arborist, that credential MUST be linked to a company otherwise we cannot verify it.

Are arborists licensed in Canada?

In most parts of the country, no. That’s one of the main reasons we created this directory: to help the public understand each company, what it’s capable of, and whether it has “crossed its t’s and dotted its i’s.”

What is WSIB clearance / workers’ compensation, and why should I care?

Search for the most dangerous jobs in North America and working around trees, as a forester or arborist, is usually near the top of the list. That’s why proper coverage matters. If a worker is injured on your property and there’s no coverage, you could be exposed. WSIB / workers’ compensation is also separate from liability insurance, which covers damage to your property, so it’s worth asking for both.

What is the difference between an arborist consultant and a tree service company?

A lot.

A tree service company does the hands-on work: pruning, removals, stump grinding, planting, cabling and bracing, storm cleanup and more. If you need someone who is guaranteed to dig in and get their hands dirty, hire a tree service company.

If you want an independent opinion first, or need a report for the city or a dispute, it’s usually best to work directly with a consultant.

In either case, it helps to make sure you’re working with a Certified Arborist or Board Certified Master Arborist.

Can I trust the information on this website?

We work hard to keep every profile accurate, but we can’t promise it’s perfect. Our information comes from public sources: each company’s own website, the International Society of Arboriculture (ISA) directory, WSIB clearance records, and Google reviews. We can misread or miss something, and companies change over time.

If anything on a profile is wrong or out of date, the company can verify its listing and update it for free, or email us at hello@arborproof.ca. We review every correction request and fix confirmed errors promptly.

Please check anything important, such as insurance or credentials, directly with the company before you hire.
