Powerline safety

Powerlines are one of our most important types of equipment — however, they're also one of the most dangerous. According to the Electrical Safety Authority, contact with a powerline is a leading cause of electrical-related deaths in Ontario. This page explains how to stay safe around downed, overhead and underground powerlines.

We also have a Powerline Safety Guide (PDF, 1.2 MB) available that outlines how to make your area safe if you're planning work near overhead powerlines.

Downed powerline safety tips

Stay back at least 10 metres from downed powerlines

All downed powerlines should be treated as live. They may be carrying power that can electrify the ground. If you come across a downed powerline, maintain a distance of at least 10 metres (about the length of a school bus) and call us immediately at 416-542-8000 (press 1) or dial 911. Never try to touch or move a powerline!

Stay inside your vehicle if a powerline lands on it

Always assume the ground around a downed powerline may be electrified. If a powerline falls on your vehicle, call 911 immediately and stay inside your vehicle until the power has been disconnected.

If you're in immediate danger, such as fire, and must leave your vehicle, don't step out of the car. Instead, jump out of your vehicle with both feet together so that you don’t touch the ground and the vehicle at the same time. Shuffle at least 10 metres away from the car to safety.

Overhead powerline safety tips

Stay at least 3 metres away from overhead powerlines

When performing activities like tree trimming, cleaning eavestroughs and more, always check for overhead powerlines before beginning work and keep yourself, your tools and your ladder a minimum of 3 metres away.

Plant trees and shrubs away from powerlines to avoid future concerns

Try to plant trees and shrubs far enough away so that when your saplings mature, they still maintain clearance requirements. For more information on clearance safety, visit our outdoor safety web page.

Call a licensed arborist

If you have trees on your property in need of trimming that are located close to powerlines, call a licensed arborist to complete this work safely.

Underground powerline safety tips

Always call or click before you dig

Underground powerlines and other electrical equipment may be buried on your property. If you're planning an outdoor project that requires digging — no matter how big or small — contact Ontario One Call to request a locate. It's the law!
