Heritage tree permit decision making criteria

The heritage tree ordinance lists the following considerations to use in determining whether there is good cause for removal or heavy pruning of a heritage tree. The heritage tree ordinance administrative guidelines offer further explanation on each criterion. 

A permit application does not guarantee the approval of the proposed tree removal(s), but the applicant may submit a heritage tree appeal form within a 15-day time frame.
