Trees provide many important benefits to the community, including cooling and shade, wind protection, drainage management, wildlife habitat, improved aesthetics and curb appeal, and added privacy through sound and light buffering from nearby streets. Protecting existing trees—especially large, mature ones—is essential, as their removal results in the immediate loss of these benefits, which can take many years to replace even when new trees are planted.
Through education, community engagement, and the development of a Tree Management Bylaw, the City is working to protect and grow its urban forest by preventing unnecessary tree damage or removal during development and improving standards for tree care and maintenance.
Tree Protection and Maintenance
The following tree protection measures are required by the Interim Tree Management Bylaw to ensure trees on private property are maintained and protected for long-term health and safety throughout regular property management activities as well as building, subdivision development projects. For more details, refer to the Tree Protection Requirements guide.
During property maintenance (non-development)
Regular property maintenance activities should follow best management practices for trees as recognized by the International Society of Arboriculture (ISA) and support natural and safe growth of trees.
The following maintenance activities are prohibited by the Interim Tree Management Bylaw, unless a Tree Management Permit for the activity is approved by the City:
- Removal of trees
- Over-pruning and topping of trees
- Disturbance to tree roots (cutting or removal), especially within the Critical Root Zone
- Disturbance to soil (removal, compaction or artificial turf) within the Critical Root Zone
For more information about tree protection requirements during property maintenance, read the Tree Protection Requirements document or review the Interim Tree Management Bylaw.
In addition to the City’s reference documents, the following website provides valuable tree management resources for property owners: treesaregood.org/treeowner.
During building and development projects
Building and development projects will be required to retain a certified Arborist to complete a tree survey, tree assessment and prepare a Tree Management Plan that will assist in the design of a construction project and protection of trees on the project site. The Arborist will be responsible for monitoring the building and development work, guide and monitor the installation and maintenance of Tree Protection Measures throughout the duration of the project. The Arborist is to submit a Letter of Undertaking before the start of the project and submit Letters of Completion at the end of construction and the end of Replacement Tree planting and maintenance.
The property owner or project manager, builder or developer will be required to submit a refundable security deposit for each Retained Tree on the project site.

Tree Removal and Replacement Permitting Process
Tree Management Permit application
Under the Interim Tree Management Bylaw, tree removal is allowed with an approved Tree Management Permit. There are two types of permits:
