Electrical Services in Markham
Tron provides electrical services for homes, condos, commercial properties and other buildings throughout Markham. We handle projects ranging from smaller electrical troubleshooting and installations to complete panel upgrades, service upgrades, EV charging, lighting systems and major commercial electrical work.
Markham spans heritage streets in Unionville and Markham Village and newer estate communities in Cathedraltown, Angus Glen and Cachet. Older services were sized before EV charging, central air and finished basements were normal, while newer homes come to us for Lutron control, landscape lighting and backup power.
Markham covers an unusually wide range of property types for one city. Markham Village and Unionville have heritage and older detached homes, some genuinely century-old, where undersized services, ungrounded circuits and layered additions are common. Angus Glen, Cachet and Cathedraltown bring large newer detached and estate homes with pools, finished lower levels, elevators in some cases and heavy connected loads. Around Highway 7, Markham Centre and Warden there are dense condo towers, townhouse blocks and street-level commercial. Markham is also home to one of Canada's largest concentrations of corporate offices and technology facilities, along Highway 404 and 407. Our work here therefore includes heritage rewiring and service upgrades, estate-home lighting control and landscape lighting, condo-unit electrical work, and substantial commercial and office fit-ups.

Choosing an Electrician in Markham
When hiring an electrician in Markham for a renovation, the project stage matters. Wiring can be planned differently when walls are open than when rooms are already finished.
Let us know whether construction or landscaping is underway, and which finishes need to remain intact. Those details help define wiring routes and installation timing.

EV Charger Installation in Markham
We install Level 2 EV chargers for Markham homes. We also install Level 3 / DC fast charging for commercial and fleet sites. 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.
Detached Markham homes generally have attached garages and private driveways, so a dedicated hardwired Level 2 charger is a short, clean install. Older Markham Village and Unionville properties can have detached garages, shorter driveways and 100A services, which makes the load calculation and the cable route the deciding factors. Townhome owners near Highway 7 need routing planned around garage layout and panel location. For Markham's condo buildings and the office campuses along Highway 404 and 407 we install multi-space, visitor and employee charging with metering and load management.
- Level 2 residential EV charger installation
- Level 3 / DC fast charging for commercial sites
- Electrical load calculations before installation
- Dedicated EV circuits, hardwired or NEMA 14-50
- Panel & service upgrades where capacity requires it
- ESA permits and inspection handled
Outdoor & Landscape Lighting in Markham
Outdoor lighting is one of the specialties Markham 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 Markham
We design, install and program Lutron HomeWorks, RadioRA 3 and RadioRA 2 systems in Markham. 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.
Electrical Troubleshooting, Pot Lights & Small Electrical Jobs in Markham
Not every job is a major installation. We take smaller electrical work too. Our licensed electricians handle:
- Breaker troubleshooting and tripping circuits
- Dead outlets and flickering lighting
- Switches, dimmers and receptacles
- GFCI and AFCI protection
- Dedicated circuits for appliances, workshops and air conditioning
- New circuits, pot lights and indoor lighting
These are service calls on the electrical system itself: wiring, circuits, panels, devices and lighting. Not sure if a job is too small? Call us. Markham service calls are booked the same way as our larger projects.

On the retail side we wire restaurants, shops and plaza units in Unionville, Markham Village and along Warden and Kennedy, working outside business hours where the tenant needs it.

Installation, permits and ESA inspection

Electrical Panel & Service Upgrade Experts in Markham
A service upgrade in Markham 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 Markham 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.
Markham panel work depends heavily on which Markham you are in. In Markham Village and Unionville the classic job is a 100A to 200A service upgrade on an older home, frequently with a fuse-to-breaker conversion, a rebuilt service entrance and grounding and bonding brought up to current requirements. In Angus Glen, Cachet and Cathedraltown the service is modern but the load has grown — pool equipment, heat pumps, EV charging, secondary kitchens, workshops — so the electrical load calculation determines whether the answer is a larger service, additional subpanels or load management. In condos we work within the unit's panel capacity. Where a service upgrade is required, Tron handles the permit, the Alectra Utilities disconnect and reconnect, and the ESA inspection.
One electrical contractor manages the process from Hydro coordination through ESA inspection.
