Environmental Regulations

We take our environmental responsibilities very seriously.

Our forestry team is made up of qualified foresters who are trained to understand natural ecosystems and tree development. Our forestry technicians ensure that compatible species and low-growing shrubs remain along power line rights-of-way. These plants don’t grow tall enough to pose a concern to line safety or reliability and they provide food and cover to wildlife.

Any proposed vegetation management applications must be approved by the Nova Scotia Department of Environment. All approvals require a buffer from watercourses and private water supplies.


The herbicide most often used by our forestry crews is Tordon 101, which is registered for use by the Pest Management Regulatory Agency (PMRA) of Health Canada.


We ensure we mitigate any potential effects on birds and their nests.


In bird nesting season, ground clearing and trimming crews are required to look for nests, chicks and eggs before they start any work. If a crew sees any signs of such activity, they must stop work and ensure a minimum 10 metre buffer around the site. If they find the nest of a larger bird, such as an osprey or eagle, the buffer zone is 100 metres. Every year, we have situations in which crews stop their work and relocate to avoid nesting birds.

Our Osprey relocation program has helped bring back the once endangered population. Our power line technicians relocate threatened nests from atop live utility poles to safer, unused poles that they place nearby. Check out our Ospreycam during the summer months to see one example of our success. Ethel and Oscar’s nest was relocated in 2001 and osprey have returned to the nest each year since to hatch their chicks.
