Tips for Hiring an ISA Certified Arborist

Things to look for when hiring an ISA Certified Arborist:

  • Certification through ISA Certified program and security clearance certificates
  • Liability insurance and workers compensation coverage on all employees
  • 1st aid, CPR and WHMIS training
  • Aerial rescue and emergency response
  • Certification for equipment being used for jobs: cranes, aerial devices, etc.
  • List of references
  • Contacting Hydro to obtain line clearance for safety of workers (10’ clearance needed from primary lines)
  • Obtaining proper permits such as City of Ottawa Distinctive Tree Permit, road encroachment and closure permits if needed (extra charges apply)
  • Traffic control following Book 7 for safety of workers and pedestrians
  • Avoid companies that top trees (this practice has been proven to decline trees now for over 20 years yet is still a problem today)
  • Avoid companies knocking door to door as well established companies are busy enough that this is not needed
  • Avoid hiring companies that don't have their own workers and only subcontract your work to smaller companies with inadequate insurance coverages. These types of companies are often more expensive because they are simply adding a finder’s fee of 20% – 40%. If a major accident happens you could be surprised of the outcome.
  • Make sure all wood related material is diverted from the landfill site and properly recycled
  • EAB (Emerald Ash Borer) infested wood to follow the CFIA (Canadian Food and Inspection Agency) guidelines and regulations.
