IMPORTANT REMINDER ABOUT PAD-MOUNT TRANSFORMERS
Those green metal hydro boxes found in neighbourhoods are pad-mounted transformers — and they must remain accessible and clear at all times for safety and emergency repairs.
Ontario utility guidelines generally require:
✅ 3 metres (10 feet) of clear space in front of transformer doors
✅ 1–1.5 metres of clearance on the sides and back
🚫 Please DO NOT plant trees close to transformers.
Tree roots and overgrown vegetation can:
- crack or lift the concrete pad
- block utility worker access
- interfere with cooling and ventilation
- delay emergency response during outages
Several Ontario utilities specifically advise:
👉 “Don’t plant trees near pad-mounted transformers.”
✅ Acceptable landscaping may include:
- low ornamental shrubs
- grasses
- mulch beds
- shallow-rooted plants
🚫 Avoid planting:
- cedars
- maples
- spruce
- willows
- vines / ivy
- thorny or invasive-root plants
⚠️ BEFORE YOU DIG IN ONTARIO:
Always request underground utility locates through
Ontario One Call
at least 5–7 business days before digging.
Protect yourself, your property, and underground infrastructure by planning landscaping safely around electrical equipment.
