Tron Electrical electrician replacing a commercial electrical panel in a Toronto facility

Commercial Panel Replacements Done Clean and Documented

Our licensed electricians replace aging commercial panels and switchgear with properly sized, fully labelled distribution gear — ESA permitted, Hydro coordinated, and scheduled around your operating hours.

The Three Questions Owners & Property Managers Ask

“We can't shut the building down for this.”

We plan the cutover around your hours — nights, weekends or a phased circuit-by-circuit transfer with temporary feeds. The shutdown window is agreed in writing before we order gear.

“How do we know the retrofit will actually pay back?”

We measure existing fixture counts, wattage and run hours, then quote the retrofit with a projected kWh and maintenance saving alongside available Save on Energy incentives — numbers you can hand to ownership.

“Who deals with ESA and the landlord's requirements?”

We do. Permits are pulled under our ECRA/ESA licence, we submit drawings and insurance to property management, and we meet the inspector so you get sign-off without chasing anyone.

⭐⭐⭐⭐⭐ Trusted by GTA businesses with 500+ five-star Google reviews.

"Tron upgraded our panel and installed our Lutron keypads — flawless, on time, and the cleanest wiring we've ever seen."
M. Chen — Forest Hill
"Knowledgeable, punctual, and a pleasure to work with. They explained every option and the result is gorgeous."
S. Patel — Kleinburg
"Three quotes, one obvious choice. Tron delivered above expectations and the system has been perfect for over a year."
D. Rossi — Oakville

Modern Power & Lighting for Serious Commercial Operations

Outdated commercial panels limit growth, raise energy costs, and create real safety and insurance risk. Old fluorescent lighting wastes power and degrades working conditions every shift.

Tron Electrical has upgraded GTA commercial services and lighting systems since 1972 — ESA permitted, Hydro coordinated, scheduled around your operating hours, and finished clean.

Complete coordination from load study to ESA sign-off. We handle permits, utility coordination, shutdown planning, installation, rebate paperwork, and final inspection — so facility managers never have to chase utilities, inspectors, or paperwork themselves.

Old Commercial Gear vs. Tron Electrical Upgrade

If your facility shows any of these warning signs, it's time to upgrade — before it becomes downtime, an insurance issue, or a code violation.

Warning Signs

  • Undersized service for new equipment or expansion
  • Aging FPE / Stab-Lok / pushmatic or 30+ year old switchgear
  • Frequent breaker trips, hot panels, burn marks
  • Fluorescent / metal halide lighting wasting energy
  • No lighting controls, occupancy sensors, or daylight harvesting
  • ESA orders, insurance requirements, or failed inspections

EV Charger and Load-Capacity Assessment

An EV charger panel upgrade is not always necessary. Homeowners can request an hourly electricity-consumption report from their Hydro utility. We review this information with an electrical load calculation to determine whether:

  • the existing 100A electrical service has sufficient capacity;
  • an EV energy-management system can avoid a service upgrade; or
  • a full 100 amp to 200 amp panel upgrade is required.

A subpanel adds breaker space but does not increase the total electrical capacity available to the home.

We also replace outdated fuse panels, Federal Pioneer and Stab-Lok electrical panels, and coordinate Toronto Hydro disconnect and reconnect requirements, ESA permits and inspections.
