We are responsible for vegetation management on road allowances, but not tree trimming or maintenance of trees and vegetation on customer property. This is the responsibility of the owner. See the diagram below to see the difference between our power lines and privately-owned lines.

Pick the right plants, pick the right place
When planting trees on your property, avoid planting trees near any power lines or electrical equipment, such as poles, to ensure newly planted trees and shrubs never interfere with nearby power lines or electrical equipment.
If a tree must be planted near a power line on your property, first check with your municipality to ensure all by-laws are followed and that any easements on your property are respected.
The best place to plant tall-growing trees is at least 8 metres away from overhead power lines. Tall-growing trees include Colorado spruce, white pine, and sugar maple.
The medium zone is from 5 - 8 metres on either side of overhead power lines. Plants in this area should not exceed 8 metres at maximum height. Medium-growing trees include serviceberry, ornamental pear, and white cedar.
The low zone is directly under the power lines and extends 5 metres on either side of the overhead power lines. Plants in this area should not exceed 3 metres at maximum height. Please keep a 5 metre area around poles clear of vegetation. Plants in this area obstruct maintenance work and emergency restoration efforts. Low-growing trees and shrubs include dogwood, honeysuckle, and silverberry.
