Arborist reports
Arborist Reports
An Arborist Report shows what a tree expert finds. These reports can be used for many things. They can help you get a building permit. They also check if trees are healthy, safe, or if they need care. Our reports give clear details about your trees. We explain what the trees need to stay strong and safe. This helps you make good choices and follow local rules. With our Arborist Reports, you’ll know how to take care of your trees and protect them during projects.
Tree Protection Plans
Tree protection plans
A Tree Protection Plan helps keep trees safe during building projects. Our arborists make a plan to show where trees are and how close they are to work areas. We explain how to protect roots, branches, and trunks. These plans keep trees healthy and strong. They help you follow local rules and protect trees during construction.
Butternut Health Assessments
Butternut health assessments
We offer specialized assessments for Butternut trees, evaluating their health and providing conservation strategies for this endangered species.
Site Monitoring
Site Monitoring
Arborist Site Monitoring helps keep trees safe during construction. Many towns require this to make sure trees don’t get damaged by accident. Our arborists check trees while crews are working nearby. If roots must be damaged, we prune them following best arboricultural practices to help the tree recover. We look for harm to roots, trunks, or branches and make sure trees stay healthy and strong. With site monitoring, we protect trees during building projects.
Tree Protection hoarding
Tree Protection hoarding keeps trees safe during construction. This hoarding is usually a sturdy fence placed around the tree. It protects the roots, trunk, and branches from damage. Towns usually have specifications detailing how to install the hoarding. We know and follow these rules to make sure it meets your local standards.

Tree Risk Assessments
Tree risk assessment
Our arborists are TRAQ certified. TRAQ stands for “Tree Risk Assessment Qualification”. It’s a program by the ISA (International Society of Arboriculture). This means they know how to check trees for risks. With this training, they learn how to find weak branches and check tree health. They look for any signs that could be unsafe. When we check your trees, we use simple steps to look for danger. Our goal is to keep your property safe and your trees healthy. We give you all the information you need. With a TRAQ-certified arborist, you get expert advice to keep your trees safe and strong.
SEE THE FOREST, SEE THE TREES
Moving Your Projects Forward
Nowhere is it written that urban development must come at the expense of our natural environment. Or, that development must stop to protect the trees. Our mission is to simplify urban forestry regulatory compliance, so that you can get on with your construction projects without compromising the health of our valuable urban forests. We are committed to balancing progress and environmental stewardship, ensuring that our clients can achieve their development goals without unnecessary delays or complications.
Our business arose from the frustration faced by our clients with the complex, expensive, and lengthy building permit process, particularly due to tree protection bylaws. These by-laws are necessary but bewildering hurdles that can delay projects and adds costs that are often avoidable. We offer a simplified, efficient solution for construction projects in the Greater Toronto Area (GTA).


Focusing on Individual Trees
While we see the forest, we never lose sight of the trees. Each tree is unique, with its own needs and challenges. Our detailed assessments consider factors like species, age, health, and location. This meticulous attention to individual trees allows us to provide targeted care and management strategies that benefit both the tree and its surroundings.
