Car parking under a transmission line

To ensure the safety of the public and employees, service continuity and the maintenance of the network, Hydro-Québec must exercise control of the use of power line rights-of-way and encroachments onto substation property.

Hydro-Québec teams regularly inspect and carry out maintenance work in rights-of-way. The inspections aim to check the condition of the equipment and ensure that those who use the rights-of-way comply with Hydro-Québec regulations. Any encroachment or unauthorized activity may be subject to a non-compliance notice.

In addition, Hydro-Québec personnel regularly check the transformer substation peripheries to make sure that an area of 1.5 m on either side of the fence is clear (no vegetation, snowbanks, equipment or materials).

Don’ts in transmission rights-of-way

  • Building or expanding a structure (house, garage, hangar, shed, tank, etc.)
  • Modifying the ground elevation by digging or adding material (no excavating, no filling)
  • Storing or stacking (wood, snow, earth, waste, debris, materials, etc.)
  • Installing a pool (above-ground or in-ground)
  • Installing a trampoline, water-play structure, camping trailer or clothesline
