What You Need to Know

Well-maintained trees provide many benefits to your property, but poorly maintained trees can be a significant liability. Arborists specialize in the care and maintenance of individual trees, but there are some things to consider before hiring a company. Professionals who are specifically trained to work safely in trees should be the only ones performing work on trees.

Services that Arborists Provide

  • Pruning for tree health, maintenance, or safety;
  • Tree removal and/or stump grinding;
  • Emergency tree care and/or tree care around power lines;
  • Tree planting;
  • Pest/disease diagnosis and treatment;
  • Risk mitigation;
  • Soil amendments and aeration;
  • Consulting and legal services relating to trees.


In Manitoba, an arborist must have at least one of the following credentials to practice Arboriculture (The Forest Health Protection Act, 2018):

  • Hold and maintain arborist certification from the International Society of Arboriculture (ISA);
  • Have in their possession a previously issued Manitoba Arborists Licence that was valid after October 1, 2017;
  • Have proof of completing the Manitoba Arborists Training Course from the University of Manitoba before July 1, 2019.

ISA Certified Arborists have achieved a measurable level of knowledge in the art and science of tree care. These professionals have hands-on experience and successfully passed a comprehensive exam (developed by leading tree care experts). ISA Certified Arborists also continue their education to maintain their certification and are more likely up to date on the latest treatments and techniques.

The ISA also offers membership to anyone in the tree care industry, including students in forestry or related fields. No exam is required for membership, and membership is not the same as a certification.


In Manitoba, there is no agency regulating that an arborist has obtained liability insurance. Without insurance, the homeowner could be held liable for any damage to the property, injury or damage to a third party, or injury to the arborist. It is the homeowner’s responsibility to ask an arborist for proof of liability insurance and phone their insurance company if you are not satisfied.
