You do not need a permit to prune a tree if you follow good arboricultural practices to keep the tree healthy. The City recommends hiring a certified arborist or qualified tree care specialist for any tree work.
You must request a permit exception from the City for the following:
- Imminently Hazardous Trees: Privately owned trees that pose an immediate danger must be removed at the property owner's expense.
- Terminally Diseased Trees: Not all diseases will kill a tree. Trees that are terminally diseased and cannot be maintained may qualify for a permit exception. However, you still need a permit for trees in poor condition.
- 100% Dead Trees: A permit is not required to remove a completely dead tree.
- Ash Trees: No permit is needed to remove ash trees infested with Emerald Ash Borer. Contact 311 for an exception.
- Grade Changes: The City of Toronto will require evidence that Toronto and Region Conservation Authority (TRCA) has issued a permit within areas that are regulated by the TRCA, and where no tree removal or injury is planned.
How to Obtain a Permit Exception
To request a permit exception, send your request to the local Tree Protection and Plan Review District Office via email or in person. Contact information is provided below. Include the following information:
- Name of the registered property owner
- Property address
- Name of arborist and company (if applicable)
- Photos of the tree(s)
- Tree details:
- Species
- Diameter (cm)
- Location on the property
- Description of the tree’s condition and reason for the request
You must receive confirmation from the City before removing or injuring a By-law protected tree unless it’s an emergency. We encourage planting a new tree to replace any removed. If Urban Forestry determines that a tree does not qualify for an exception, you can apply for a permit.
