Local tree-rule guide
Niagara Falls tree rules
Ordinary private-tree maintenance/removal is primarily an owner/civil matter; boundary trees require shared-owner consent under Ontario law.
The local rule
Niagara Falls’ urban-forestry program and tree bylaw focus on municipal trees; the City states that it does not maintain private trees or decide private boundary-tree disputes.
A tree near the street should first be checked for ownership because City trees and privately owned trees follow different responsibilities.
Application details
Niagara Falls starts with ownership, not a blanket private-tree permit threshold
- The City’s current forestry page is much clearer about ownership and special situations than it is about a universal private-yard permit.
- For most homeowners, the useful decision is whether the tree is municipal, private, shared on a boundary, hazardous or affected by construction.
Niagara Falls says that if half or more of the tree is on the road allowance, the City takes responsibility. If less than half is on the road allowance, the tree is considered private.
No one may remove or damage a tree on public property. Report a damaged, diseased or hazardous City tree instead of arranging the work yourself.
The City says it does not remove or trim private trees and directs owners to certified arborists or tree-service companies. Its current forestry page does not establish a blanket private-tree removal permit.
A private tree that is dead, decayed, damaged and potentially hazardous can be reported to the City; a By-law Enforcement Officer investigates under the applicable property rules.
The City points residents to Ontario’s Forestry Act: where a tree base grows on the boundary between adjoining lands, it is common property and both owners must consent to work that would injure or destroy it.
Development proposals must include plans to protect and preserve private and public trees affected by construction, and arborist/tree-protection documentation may be required.
Before work starts
- Ownership: check the property line. Public and boundary trees may follow a different process.
- Site context: review any development approval, covenant or protected-area conditions.
- Work requirements: confirm any permit, exemption or protection requirements that apply to the planned work.
