Pruning involves cutting tree branches to ensure safe clearance around medium-voltage lines. Carried out mainly in developed environments (cities, suburbs, villages), pruning constitutes the bulk of Hydro-Québec’s vegetation control.
The fact that it is minimally disruptive helps to preserve habitats and maintain biodiversity- for example, in urban or suburban woodlands and green areas.
Accident prevention: Hydro-Québec periodically clears power lines. Consult the interactive map to find out when we will be in your area. To prevent accidents and reduce the number and duration of outages, Hydro-Québec periodically clears medium-voltage lines.
