The short answer is yes, but not always. There are specific requirements for each area, and Calgary has its local standards for tree removal. In Calgary, a permit is required for tree service if the tree’s diameter is more than 30cm. The same rule applies to private property. One of the perks of hiring Tree Business Inc. is that we handle all of the permits for you. We know the requirements for each area, so we are sure to meet them. We will go through the process as quickly as possible while abiding by all laws and regulations for Calgary.
