Open House

Residents were invited to learn more at an open house on Tuesday, January 16 where staff from the town’s Forestry section and Oakville Hydro were on hand to share information and answer questions. If you were not able to attend the open house and have questions about hydro line clearing, please contact ServiceOakville at 905-845-6601 or serviceoakville@oakville.ca.

Each year, the town and its tree service contractor perform hydro line clearing on behalf of Oakville Hydro to reduce safety hazards and power outages, while maintaining the health, safety and well-being of the town’s tree canopy. In rare instances, trees growing too close to the hydro line will be removed as a last resort if the arborist cannot balance the clearance standard with acceptable pruning standards.

If not properly maintained, trees can create power outages or hazardous situations by touching or even falling on hydro lines. Trees are pruned on a three-year cycle following the Electrical Safety Authority’s (ESA) industry standard of providing a minimum three-metre (10 foot) clearance. Our professional arborist contractors prune trees with these goals in mind:

  • Keep the structural integrity of the tree intact
  • Maintain the health of the tree with well-placed cuts that heal well and minimize sprouting
  • Promote regrowth away from hydro lines through directional pruning
  • Leave branches growing down and away from wires to continue their growth

In some instances, the town must prune privately owned trees if they have grown too close to the hydro line. When hydro lines are located in rear yards, Oakville Hydro has an easement through the property which allows the arborist to access the tree.
