Electrical Services in Thornhill
Tron provides electrical services for homes and condos throughout Thornhill. We handle projects ranging from smaller electrical troubleshooting and installations to complete panel upgrades, service upgrades, EV charging and lighting systems.
Thornhill straddles the Vaughan and Markham sides of Yonge Street, and much of its housing stock dates from the 1960s through the 1980s. That means a lot of 60A and 100A services, original panels and aluminum branch wiring in homes that now need to run air conditioning, EV charging and a renovated kitchen. Alongside that upgrade work, we install Lutron lighting control, landscape lighting and security systems for homeowners renovating rather than moving.
Thornhill is one of the oldest established parts of the GTA we serve, and the housing stock shows it. Old Thornhill and Royal Orchard are dominated by mature detached homes from the 1950s to 1970s where we regularly find original panels, aluminum branch wiring, undersized services and additions wired at different times to different standards. Thornhill Woods, Uplands and the Grandview area include newer detached and larger executive homes with modern wiring but growing loads. Along Yonge Street and Bathurst there are also townhouse blocks and low-rise apartments. Our Thornhill work therefore runs from careful troubleshooting in older homes — tripping breakers, dead outlets, mixed wiring types — through fuse-to-breaker conversions and 200A service upgrades, to pot lighting, Lutron dimming retrofits and exterior lighting on the larger properties.

Choosing an Electrician in Thornhill
Need an electrician in Thornhill for a recurring fault? Describe the symptoms—a tripping breaker, dead receptacle or flickering lights—rather than assuming which part needs replacing.
For a renovation, tell us which rooms are affected and whether walls are open. That helps us plan access to the existing wiring.

EV Charger Installation in Thornhill
We install Level 2 EV chargers for Thornhill homes. Every install starts with an electrical load calculation on your existing service, so the charger is sized correctly. We then run a dedicated EV circuit, hardwired or NEMA 14-50, to where you park. If the service cannot carry the added load, we upgrade the panel and service in the same project. We handle the ESA permit and inspection.
Older Thornhill homes usually have private driveways with an attached or side-drive garage, but a 100A service already carrying central air and a finished basement. That makes the load calculation the deciding step: sometimes a Level 2 charger fits with load management, and sometimes the service upgrade comes first. Newer Thornhill Woods and Uplands homes generally have the capacity and simply need a clean dedicated circuit to the garage wall. For townhome and low-rise blocks along Bathurst and Yonge we assess panel location and routing before quoting the run.

Outdoor & Landscape Lighting in Thornhill
Outdoor lighting is one of the specialties Thornhill homeowners call us for most. That includes:
- Architectural lighting on stonework and rooflines
- Garden and pathway lighting
- Tree and feature lighting
- Pool-area and patio lighting
- Motion and security lighting at entries and driveways
We run the outdoor electrical and set the transformers and controls. Then we aim and time the fixtures, so the property looks right after dark rather than merely lit.
Outdoor circuits, pool and hot tub bonding and exterior receptacles are installed to the Ontario Electrical Safety Code. ESA inspects the work where required. Controls can run on timers, photocells, astronomic scheduling or a Lutron system, so the whole property comes on together.
Lutron Lighting & Automation in Thornhill
We design, install and program Lutron HomeWorks, RadioRA 3 and RadioRA 2 systems in Thornhill. We do this in new builds and as retrofits in established homes. That work covers:
- Keypad layout, LED dimming and load compatibility
- Motorized shades, including Palladiom
- Occupancy and daylight sensing
- Scene programming and smart thermostats
- Voice-control integration
Advanced lighting control is a core part of our work, not an add-on. The system is commissioned properly and usable the day it is handed over.

How It Works
Talk to a licensed electrician
Tell us what you want to add or change in your Thornhill home. We ask the questions that determine whether your existing service can carry it.
On-site assessment and written scope
We assess the existing service, panel, grounding and layout, then set out exactly what the work involves and what it costs before anything starts.
Installation, permits and ESA inspection
We complete the work and handle the required electrical permits, Alectra Utilities coordination and ESA inspection where they apply.
Electrical Panel & Service Upgrade Experts in Thornhill
A service upgrade in Thornhill is more than a new panel. Our licensed electricians plan the work and apply for the required electrical permits. We coordinate the Alectra Utilities disconnect and reconnection, complete the upgrade and arrange ESA inspection. Utility and ESA appointment times are set by them, not by us. We book them and keep you informed.
Our Thornhill work covers electrical panel upgrades and panel replacement, 100A service and 200A service installations, 100A to 200A service upgrades, fuse-to-breaker conversion, electrical load calculations, Hydro coordination and ESA inspection.
Thornhill has a high share of homes whose electrical service has never been touched since it was built, so panel replacement and 100A to 200A service upgrades are steady work here. Aluminum branch wiring and older fuse panels turn up often, and both change how a panel change should be done: correct terminations, AFCI or GFCI protection where required, and proper grounding and bonding rather than simply swapping the enclosure. Additions, second-floor extensions and finished basements common in Old Thornhill add load that the original service was never sized for. We complete the electrical load calculation, pull the permit, coordinate the Alectra Utilities disconnect and reconnect, and schedule the ESA inspection.
One electrical contractor manages the process from Hydro coordination through ESA inspection.
