The local rule

Thunder Bay says the City is responsible for maintaining trees on municipal property and that public-tree removal is considered when condition or safety warrants it.

The City’s current urban-forestry review identifies its Urban Forest Management Plan and Tree By-law as the main municipal tree-policy documents; homeowners should confirm whether a particular tree is municipal or private before arranging work.

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.
