In conjunction with the newly implemented Tree Protection By-Law, the annual licensing of certified arborists, arboricultural companies and landscaping/tree companies provides added protection to the town's urban forest and consumers.
Licensing is similar to the licensing of existing private industries such as landscapers, pool contractors, HVAC installers and fence installers.
On April 2, 2018, Council approved the licensing of Arborists in Oakville.
