The short answer is: Yes, if it meets specific size requirements.
In London, Ontario, the Distinctive Tree By-law protects any tree on private property with a trunk diameter of 50cm (19.7 inches) or wider. If your tree meets this size threshold, you must obtain a permit before cutting it down. Failure to do so can result in significant municipal fines.

Why You Might Need a Tree Removal Permit
London takes its "Forest City" nickname seriously, and City Hall enforces strict regulations to preserve the urban canopy. However, removal is often necessary for safety or property development. The City typically approves permits for the following reasons:
Construction & Renovations: Are you planning a home addition, pool, or new driveway? If a tree obstructs the build, you will likely need a removal permit or a protection plan before construction begins.
Disease & Infestation: Trees suffering from the Emerald Ash Borer or severe fungal infections often require removal to prevent the spread of disease to surrounding greenery.
Safety Hazards: Southern Ontario storms can cause severe damage. If a tree has a split trunk or leans dangerously toward your home, it becomes a liability that requires immediate attention.
Landscape Changes: While removing a healthy tree for aesthetics is difficult, a professional arborist can help you navigate the application if you propose a viable replanting plan.
The "50cm Rule": How to Measure Correctly

Many homeowners accidentally measure their trees incorrectly. To determine if your tree is "Distinctive," you must measure the diameter (width) at breast height (1.4 meters or 4.5 feet off the ground), not at the base.
Do You Need an Arborist for the Permit Process?
Navigating the Distinctive Tree By-law paperwork can be confusing. In most cases, you cannot simply fill out the application yourself; the City requires an Arborist Report to validate the removal request.

Tree Removal Cost Breakdown: Permits vs. Service
When budgeting for tree removal in London, you must account for two separate costs: the City's administrative fees and the physical removal service.
1. The Permit Fees
The City of London charges an application fee for a Distinctive Tree Permit (approximately $100, subject to change). Keep in mind that fines for illegal removal start at $500 and can escalate into the thousands for severe infractions.
2. The Removal Service
For the physical work, pricing varies based on tree height, location, and rigging complexity.
Small Trees (under 30 ft): $150 – $450
Medium Trees (30–60 ft): $450 – $1,000
Large Trees (60 ft+): $1,000 – $2,000+
Complex removals—such as a large Maple overhanging a glass conservatory require specialized safety equipment, which will influence the final quote.
