What is an Arborist/Tree Surgeon?
An Arborist, also known as a Tree Surgeon, is a certified tree care professional responsible for the maintenance, preservation, and safe removal of trees and shrubs in a variety of environments. Arborists are trained in the biology and health of trees and woody plants, using specialized techniques and equipment to ensure both safety and ecological balance.
In Canada, arborists are critical to maintaining the health of urban forests, enhancing biodiversity in municipal parks, and protecting infrastructure from storm damage and overgrowth. Their work involves both ground-level and aerial operations—often in challenging weather and terrain conditions. This trade requires a strong understanding of plant science, physical stamina, and a firm grasp of Canadian safety standards and environmental regulations.
Key Responsibilities
Arborists perform a wide range of tasks involving tree assessment, maintenance, and removal. They work in residential areas, commercial developments, public green spaces, and protected conservation zones.
1. Tree Pruning and Removal
Using climbing harnesses, bucket trucks, or cranes, arborists trim dead or hazardous branches and safely remove trees. Tasks are often performed at height, with chainsaws and rigging systems designed to prevent property damage and ensure worker safety.
2. Tree Health Assessment
Arborists evaluate the condition of trees through visual inspection, core sampling, and pest identification. They diagnose diseases such as Dutch elm disease, cedar root rot, or emerald ash borer infestations—issues prevalent in various Canadian provinces.
3. Soil and Root Care
Healthy trees require healthy roots. Arborists conduct root collar excavations, soil aeration, and fertilization treatments. They may also manage water runoff or compacted soil issues, particularly in urban areas like Toronto, Calgary, and Vancouver, where soil degradation is common.
4. Emergency Response
During natural disasters, storms, or wildfires, arborists are on the front lines. They clear debris from roads, power lines, and buildings. Emergency arborist services are critical in provinces with seasonal weather risks such as British Columbia, Ontario, and Quebec.
5. Equipment Operation and Safety
Arborists operate chainsaws, stump grinders, wood chippers, and aerial lifts. Canadian arborists are required to follow WHMIS, CSA-approved fall protection systems, and provincial occupational health and safety regulations.
