A permit is required to remove most trees on private property, and the application needs an arborist report from a certified arborist. - The two exceptions are a tree that is dead or hazardous and an immediate threat to public safety, and ash trees infested with Emerald Ash Borer. - Trees over 30 cm in diameter require a distinctive tree permit. - Tree King does not top trees. Topping causes wounds trees struggle to heal. Crown reduction is the correct way to reduce a tree's height. - The best time to prune most Ottawa trees is late winter or early spring, before leaves have bloomed. Oak and Elm can be pruned in late fall. - Winter is often the best season for removal: frozen ground, dormant trees, and lighter, leafless material. - Stump grinding is NOT included with general tree removal; it is a separate job requiring different equipment. Ask for it when quoting. - Stump grindings do not attract termites. They make good organic mulch. ## More - [Areas We Serve](https://treekingottawa.ca/service-areas/) - [FAQs](https://treekingottawa.ca/ottawa-tree-service-questions/) - [Blog](https://treekingottawa.ca/blog/) - [Contact](https://treekingottawa.ca/contact-ottawa-tree-service/)
