Trees and power service lines

For the reliability of power to your home, you should make sure there is at least 1 m clearance between your service line running from the power pole to your home and any trees or shrubs. This clearance area helps to reduce the chances of a tree coming in contact with the power line and causing a power outage or fire.

​Utility locating is a free service

Click before you dig or call Utility Safety Partners at 1 (800) 242-3447 to find out where the utility lines are located in your yard. The service will mark the location of power, water, drainage, natural gas, internet, and cable television lines on your property with coloured paint and flags. This service can take up to a week after you make the call.

Plan out what trees and shrubs
to plant and where

When choosing which trees and shrubs to add to your yard, pay attention to the how high they might grow and their proximity to utility lines. If you live in an area with overhead power lines, a clearance of 3 metres helps reduce the chances of a tree coming into contact with the power line and causing a power outage or fire.

There are four zones to consider when planting near overhead power lines.

Four zones

Zone 1

1 metres from the power pole – no digging is to occur here.

Zone 2

Within 5 metres of the power line – maximum height of a mature tree/shrub is 6 metres.

Zone 3

5 to 10 metres from the power line – maximum height of mature tree is 12 metres.

Zone 4

Beyond 10 metres from the power line, any height of tree is acceptable.

Your local greenhouse is a good resource for more information on the mature heights of trees.

 

 

Note: For the overhead power service line to your house, keep the tree or shrub at least 1 metre away from the line.

 

Working with professional arborists

If you have hired a contractor to help with tree and stump removal, make sure they have experience trimming trees near power lines. Certified utility arborists are trained to safely maintain trees and vegetation growing near power lines, arborists without this designation are at risk of devastating injury or even death.

If certain safety measures are not taken, the entire tree and surrounding area can become energized and anyone working or passing by below are also at risk of electrical shock or electrocution.

Even if someone doesn't directly make contact, electricity can arc or "jump" from the line to their equipment.

For a list of arborists that are certified Utility Specialists visit the International Society of Arboriculture, Prairie Chapter.
