Compatible and Incompatible Vegetation
We maintain vegetation growing on or beside right-of-ways beneath our power lines. We promote the growth of the type of vegetation defined as Compatible Vegetation. Compatible Vegetation rarely grows to a height that would interfere with the safe operation of our power lines. Incompatible vegetation includes any plant or tree species that could grow within the required clearance area.
Our practices may include any of the following methods:
Removing incompatible vegetation, such as trees and brush from right-of-ways
Trimming or pruning branches of surrounding trees to meet clearance standards
Removing vegetation that could interfere with access to right-of-ways in an emergency
Removing trees that could interfere with the safe and reliable delivery of electricity
Clearing rights-of-ways and re-seeding areas with a compatible ground cover mixture
Selectively applying herbicide, if agreed to by the landowner, to prevent re-growth.

Environmental Practices and Preservation
In many cases, trimming certain species of plants can encourage more stems to sprout from the established root system. This can increase the density and amount of vegetation over time.
To help prevent this and encourage the growth of other low growing vegetation, we endeavour to treat plants with a low volume, direct application herbicide that is federally and provincially approved.
Right-of-ways have been maintained by selectively treating vegetation with herbicides to promote the growth of low-growing plant communities. This vegetation provides excellent habitat for small animals, controls erosion, and becomes a natural deterrent to the growth of undesirable vegetation.
Before applying herbicides on private property, we seek permission from the landowner and municipal authorities. Herbicides are applied by our forestry professionals who are properly licensed, certified, and supervised in accordance with provincial rules, regulations, internal standards, and pesticide-specific applications.
