Commercial Electrical Work That Passes Inspection the First Time
We wire offices, retail units, restaurants, warehouses and multi-tenant buildings across the GTA — with the permits, insurance paperwork, after-hours scheduling and ESA certificates that commercial projects actually run on.
The Three Questions Commercial Clients Ask Us
“Will this shut down our operation?”
Rarely. We phase the work and book evenings, overnights or weekends for anything that requires a power-down, and we tell you the exact outage window in writing before we start.
“Our property manager needs paperwork before anyone starts.”
That is standard for us. We issue our ECRA/ESA licence number, commercial liability certificate and WSIB clearance up front, and we pull the ESA permit in our name.
“We got a much cheaper quote from someone else.”
Ask whether their quote includes the ESA permit, inspection, panel labelling and after-hours scheduling. Most low commercial quotes leave those out, and the shortfall lands on you at inspection time.

A Commercial Contractor Your Property Manager Will Actually Approve
Commercial electrical work fails on paperwork and scheduling more often than on wiring. Permits, insurance certificates, after-hours access, inspection sign-off and occupancy approvals all have to line up.
Tron Electrical has handled that end of the job for GTA businesses since 1972 — ESA/ECRA licensed, fully insured, WSIB covered, with a 99% first-pass ESA inspection rate.
We coordinate the whole job, not just the wiring. Permits, Hydro, landlord requirements, inspection scheduling and certificates are handled by us, so your team never chases utilities or inspectors.
