Do I Need a Permit to Remove a Tree in Calgary?
Many Calgary homeowners are surprised to learn that removing a tree may not be as simple as grabbing a chainsaw. In fact, depending on where the tree is located and what type it is, official approval may be required before removal. Calgary, like many municipalities, has bylaws designed to protect the urban forest and ensure that removals are handled responsibly.
Failing to follow these rules can lead to heavy fines, liability issues, and even forced replanting orders. Understanding the permitting process—and working with an ISA Certified Arborist—ensures your tree removal is done safely, legally, and with respect for the community.
Why Tree Removal Is Regulated
Trees are more than private landscaping features. They provide citywide benefits such as:
Reducing stormwater runoff.
Improving air quality.
Lowering summer heat through shade.
Providing habitat for wildlife.
Boosting property values across neighborhoods.
Because of these benefits, municipalities regulate tree removals to protect the overall canopy. Rules are especially strict for boulevard trees and trees located in preservation areas.
Boulevard Trees Are City-Owned
One of the most common misconceptions in Calgary is about boulevard trees—the ones planted between sidewalks and roadways. Even if the boulevard is directly in front of your house, those trees belong to the City of Calgary.
This means:
You cannot prune, damage, or remove a boulevard tree without official authorization.
Unauthorized removal can result in substantial fines and replacement costs billed to the homeowner.
Maintenance is usually handled by the city, though adjacent homeowners are sometimes responsible for basic watering.
If a boulevard tree is diseased, damaged, or hazardous, the city must evaluate it before any action is taken.
Private Property Trees: When Permits May Apply
For trees located entirely on private property, permits are not always required—but there are exceptions. Depending on the situation, you may need approval if:
The tree is of a certain size or heritage value.
It is located in a designated preservation area or environmental reserve.
Removal could impact neighboring properties or public infrastructure.
The tree is part of a development or construction project subject to city review.
Regulations can vary not only within Calgary but also across surrounding municipalities like Airdrie, Okotoks, and Cochrane. Checking first saves costly headaches later.
The Risks of Skipping the Permit Process
Attempting DIY removal without understanding local regulations can create serious problems:
Fines and Penalties – Cutting a protected or city-owned tree without approval can result in thousands of dollars in fines.
Liability Issues – If a tree removal damages a neighbor’s property, sidewalk, or city infrastructure, you may be held financially responsible.
Insurance Complications – Insurance providers may deny claims if work was done illegally or without permits.
Environmental Impact – Removing a tree unnecessarily reduces canopy cover and may harm local ecosystems.
Simply put: the risks outweigh the rewards.
How an ISA Certified Arborist Helps
Working with an ISA Certified Arborist is the best way to ensure your tree removal complies with local laws and is done safely. Arborists provide:
Bylaw Knowledge – Understanding Calgary’s specific rules, including elm pruning restrictions and boulevard tree protections.
Permit Guidance – Helping you complete paperwork and secure approvals before work begins.
Professional Recommendations – Assessing whether removal is truly necessary, or if alternatives like pruning, cabling, or disease treatment can save the tree.
Safe Removal Practices – Using specialized rigging, climbing, and equipment to remove trees without property damage.
Insurance Coverage – Certified arborists carry liability insurance and workers’ compensation, protecting homeowners from liability.
This professional approach eliminates the guesswork and ensures peace of mind.
Alternatives to Removal
Sometimes, homeowners assume a tree must be removed when safer, more cost-effective solutions exist. A Certified Arborist may recommend:
Pruning – Removing hazardous branches while preserving the tree.
Cabling or Bracing – Stabilizing weak unions or heavy limbs to reduce failure risk.
Disease Treatment – Managing infections like black knot fungus or fire blight with proper pruning and care.
Root Zone Improvements – Amending soil, aerating, or correcting drainage issues that stress trees.
These alternatives often save trees that would otherwise be unnecessarily lost—maintaining shade, beauty, and property value.
The Bottom Line: Don’t Cut Before You Check
Tree removal in Calgary isn’t just about having the right tools—it’s about knowing the rules. Boulevard trees are always city-owned, and even trees on private property may be subject to bylaws or permit requirements. Skipping the process risks fines, liability, and unnecessary loss of valuable trees.
Before making any decisions, schedule a consultation with an ISA Certified Arborist. A professional can evaluate the tree, explain your options, and guide you through permits if removal is truly necessary.
Your trees are living investments, and your city’s canopy is a shared resource. By following proper steps, you protect both your property and your community.
