Posting of tree permit. During the removal, relocation, or replacement of a tree, the tree permit holder and the owner must post the tree permit, and keep it posted, in a conspicuous location on the site that is visible from an adjacent street.

Measurement of the distance between a tree and a proposed or existing building under this By-law is to occur at 1.4 metres above grade, and is to be the shortest distance from a point on the main trunk of the tree to a point on the exterior wall of the proposed or existing principal or accessory building. 

Tree Counting and Measurements


 Relaxation of distance requirement. Under subsections (e) and (f) of section 5.2, if the Director of Planning is satisfied that a tree warrants retention and can survive with standard arboricultural care and appropriate construction techniques, the Director of Planning may relax the minimum distance referred to in section 5.4.
