Trees Near Power Lines in Mississauga: Who Is Responsible for What

Understanding the Responsibility: Utility Lines vs. Your Property

When a tree or branch grows near power lines in Mississauga, the question of responsibility often confuses homeowners. The answer depends on which side of the meter the tree is located and who owns the infrastructure. Your local utility company, Alectra Utilities, maintains and protects the distribution lines that run from the street to your home, but the responsibility for vegetation management is shared between the utility and the property owner.

If a tree is rooted on your property and its branches extend toward or touch the utility lines, you are legally responsible for trimming those branches back to a safe distance. This is not optional. Utilities across Ontario require minimum clearance distances to prevent electrical hazards, fires, and service interruptions. Failing to maintain this clearance can result in fines, liability for damage, and safety risks to your family and neighbours. The key principle is simple: if the tree grows on your land, you must manage it.

When Alectra Utilities Will Trim Trees Near Power Lines

Alectra Utilities will trim trees and branches that threaten the integrity of their distribution network, but only on their side of the property line and only on the utility easement. If a branch is actively touching a power line, posing an immediate risk, or has already caused damage, Alectra may respond. However, they do not perform preventive trimming on private property, and they do not trim trees for aesthetic reasons or to improve your view. Their crews are focused on maintaining service reliability and public safety.

In most cases, Alectra will notify you if your tree poses a hazard and give you a deadline to address it yourself. If you do not respond, the utility may trim the tree at your expense, and you will receive a bill for the work. This is why proactive tree trimming is far more cost-effective than waiting for a utility notice. If a storm causes a tree to fall on lines or if a branch breaks and lands on wires, call Alectra immediately at their emergency line, but understand that the cost of removal or repair may fall to you if the tree originated from your property.

Service Entrance Tree Clearance: Your Legal Obligation

The service entrance is the point where power lines connect to your home. This area requires strict clearance, and Mississauga property owners must ensure that no branches or foliage interfere with these wires. The service entrance is technically part of the utility's network, but the vegetation around it is your responsibility. Most jurisdictions require a minimum clearance of 1 metre (approximately 3 feet) in all directions from the service entrance wires, though this can vary based on voltage and local regulations.

If you are planning any landscaping, tree planting, or Tree Pruning & Crown Reduction work near your service entrance, you must first contact Alectra Utilities to confirm the exact location and clearance requirements. Never assume you know where the lines are. Many homeowners discover the location only after an accident or a utility notice. Hiring a certified arborist to assess your trees and manage clearance around the service entrance is the safest approach. Credit Valley Tree Trimming can evaluate your property, identify hazards, and ensure compliance with all local requirements.

What to Do If a Tree Is Touching Power Lines

If you notice a branch touching or very close to power lines on your property, do not attempt to trim it yourself, and do not allow anyone to climb the tree or use a ladder near the wires. Even if the line appears inactive, it carries electrical current and poses an extreme electrocution risk. The correct steps are to first call Alectra Utilities to report the hazard, then contact a certified arborist or tree service to perform the work safely.

Power Outages and Tree Damage: Who Pays

When a tree or branch falls on power lines and causes an outage affecting your home or neighbourhood, Alectra Utilities will typically remove the debris and restore service at no cost to you. However, if the tree originated from your property and caused damage to the utility infrastructure, poles, or transformers, you may be liable for repair costs. Alectra has the right to bill property owners for damages caused by trees they failed to maintain. This liability can be substantial, ranging from hundreds to thousands of dollars depending on the extent of the damage.

The financial and legal risk of allowing trees to overhang power lines is significant. A single storm or high wind event can cause a tree to fail, damage utility equipment, disrupt service to multiple properties, and result in your receiving a substantial bill. Regular inspection and professional trimming eliminate this risk. If a tree on your property has caused a power outage in Mississauga, document the incident, report it to Alectra, and consult with a tree service to prevent recurrence. Prevention is always less expensive than liability.

Hiring a Professional Arborist for Power Line Clearance

Attempting to trim trees near power lines without professional expertise is dangerous and often ineffective. A certified arborist understands tree biology, structural integrity, and the proper techniques to remove branches without weakening the tree or creating future hazards. They also know the local bylaws and utility requirements that govern tree work in Mississauga. When you hire a professional, you gain liability protection, insurance coverage, and the assurance that the work meets all safety and regulatory standards.
