FAQ

The City of Ottawa generally requires a permit before you remove a distinctive tree measuring 30 centimeters or more in diameter at breast height on a regulated urban property. Removing a protected tree without the required permit can result in significant fines.

Trimming focuses on shaping and managing the overall size and appearance of a tree, while pruning targets specific branches for health reasons such as removing deadwood, crossing limbs, or structurally weak growth. Both matter, but for different reasons at different times.

Regular assessments catch weak branch attachments, co-dominant leaders, and decay before a storm does. Cabling and bracing can support structurally compromised trees, and timely pruning removes the growth most likely to fail under wind or ice load.

Stumps left in the ground attract termites, carpenter ants, and other wood-boring pests that can eventually migrate toward structures. They also create tripping hazards and take up usable yard space that could be lawn or garden.

It starts with an on-site assessment, a written quote, and permit confirmation where required. On the day of removal, the crew works systematically from the top down, protecting surrounding lawn and structures, then chips and removes all debris before doing a final site cleanup.

When a tree has significant structural failure, large sections of dead canopy, advanced root decay, or is leaning toward a structure, removal becomes the responsible call. A certified arborist assessment gives you a clear answer rather than guessing from the ground.

Late winter to early spring, just before new growth begins, is the most effective window for most Ottawa tree species. Wounds close faster, pest activity is lower, and the tree’s energy goes straight into healthy new growth.

Trees with a trunk diameter below 30 centimeters at breast height on properties of one hectare or less are generally exempt. Private ash trees confirmed to be infested with the emerald ash borer and trees posing an immediate public safety hazard are also exempt under Ottawa’s current by-law.

Most established Ottawa trees benefit from a professional assessment every one to three years, with pruning scheduled based on species, growth rate, and proximity to structures. Young trees may need more frequent attention in their early years to develop strong structure.

Costs vary based on tree size, location, site access, and whether a permit is involved. The only accurate way to know is an on-site assessment and written quote, which we provide at no charge.

Every quote starts with a free on-site visit. That way, the assessment reflects actual site conditions, access points, and tree specifics rather than a rough estimate over the phone that rarely holds up on the day of the job.

Most residential tree removals take less than a day to complete. Smaller trees may take only a few hours, while larger or more complex removals near structures can take longer. We include a project timeline in your estimate.
