Response Within 1 Hour. Premium Service.

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.
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.
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.
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.
Outdated commercial panels limit growth, raise energy costs, and create real safety and insurance risk.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.
Single-phase and three-phase service upgrades for offices, retail, warehouses and commercial facilities.
Step-down transformers, distribution panels, and tenant subpanels — properly grounded and bonded.
Warehouse high-bay, office troffer, retail accent, and exterior LED conversions with 50–80% energy savings.
Occupancy sensors, daylight harvesting, time clocks, and DALI/0-10V dimming controls.
Proper load calculations, harmonic analysis, and whole-facility surge protection.
Phased after-hours and weekend changeovers that keep critical operations online.
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.
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:
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.

From small-business 200A upgrades to 2,000A+ service replacements and full LED retrofits, Tron Electrical handles ESA permits, Hydro coordination, shutdown planning, installation, and final inspection from start to finish.
