Across Toronto and the GTA — from Rexdale’s warehouses and South Etobicoke’s industrial condos to Leaside’s business park and downtown office towers.
emergency lighting and maintenance
Emergency lighting is a legal requirement in Ontario commercial buildings, and it has to be tested monthly and inspected annually. We install, test and maintain emergency lighting and exit signs across Toronto and Etobicoke, document every test for your fire safety records, and replace batteries and units before they fail an inspection.
switchgear and distribution upgrades
Aging switchgear is a failure waiting for the worst possible moment. We inspect distribution systems in Toronto and Etobicoke commercial and industrial buildings, report honestly on their condition, and upgrade switchgear, panels and feeders where the equipment calls for it, planned around your operation so downtime stays minimal.
step-down transformers
Your service arrives at 600 volts; your building runs on 120/208. A step-down transformer bridges the two — and one unit can feed an entire building’s distribution. We install, maintain and replace step-down transformers across Toronto and Etobicoke, dry-type and oil-filled, sized from a real load check and installed with ESA permits and inspections handled.
Cobots and light automation — carton erectors, pick-and-place arms, palletizers — don’t draw much power. What they can’t survive is bad power: a surge through the panel, or a sag that scrambles the controller. We design and install the power they run on — dedicated circuits, panel capacity and surge protection, engineered in-house and installed by licensed ESA electricians.
Automation runs on power before it runs on code. When a machine goes down, when a new line needs feeding, when the panel has nothing left to give — that is electrical work, and it decides how long your plant stands still. We design, install and troubleshoot the power behind industrial automation — distribution, transformers and machine hookups across Toronto and the GTA.
Machinery, HVAC and imported equipment are often built for a different voltage than your building offers. A step-up transformer raises the supply to match the machine, so it runs correctly and safely. We install dedicated step-up transformers at the equipment or at the service, engineered in-house and installed by licensed ESA electricians.
We take on new construction electrical across Toronto and the GTA, from small restaurant build-outs and office fit-ups to larger projects such as multi-storey hotels and condominiums. Design-build or plan-and-spec, our licensed crews deliver the full electrical scope: service, distribution, lighting, life safety and final commissioning.
LED retrofit has the greatest impact on energy costs for most commercial spaces. We retrofit and install recessed, slim and canless LED lighting in offices, retail and industrial buildings across Toronto and Etobicoke, and lay out the lighting so the light lands where the work happens, not where it is wasted.
commercial electric surge protector
One surge can take out computers, point-of-sale systems and the data on them, and quietly shorten the life of everything electronic in the building. We install commercial surge protection at the panel for properties across Toronto and Etobicoke, sized to the building and the equipment it protects. If your system is older or your equipment is high-end, this is inexpensive insurance.
electrical maintenance plans and services
One plan for the whole building. Our maintenance plans and services cover scheduled electrical checks across your property in Toronto and Etobicoke: lighting, panels, emergency systems and the small repairs that become big ones when they wait. You get a calendar, written records, and priority response when something fails.
electrical distribution safety inspections
Electrical inspections are a crucial part of any maintenance plan. Our licensed electricians inspect your distribution system, check for the signs that precede failures, and report in plain language what is sound, what to watch, and what needs work now, so your building stays up to the standards your insurer and the ESA expect.
retail
From boutiques to big-box stores, we wire retail spaces that sell — track and display lighting that makes product pop, power for point-of-sale and signage, and service work scheduled around your trading hours.
Toronto and Etobicoke restaurants call us to extend patio season. We install and wire floor-standing, hanging and wall-mounted patio heaters, sized to the dining area and matched to how the space looks. New circuits, controls and timers included, with the ESA permit handled. Warmer guests stay longer, and the patio keeps earning weeks after unheated patios close.
electrical renovations
Renovating a commercial space in Toronto or Etobicoke? We handle the electrical side of the fit-out: new lighting, more power for more desks and equipment, TV and network cabling, and the panel work to support it all. One licensed crew from rough-in to final inspection, coordinated with your contractor and your schedule.
commercial EV chargers
We design and install commercial EV charging for property managers, fleets and business owners across Toronto, Etobicoke and Mississauga: Level 2 stations and DC fast chargers, load management so you can charge more vehicles on the service you already have, and ESA permits handled end to end.
Accessibility work has to be right, and it has to pass inspection. We wire universal and barrier-free washrooms and power automatic door operators and entrances for commercial properties in Toronto and Etobicoke, coordinated with your door supplier and finished to Ontario’s accessibility requirements.
distribution maintenance plans
Being proactive is the best insurance your building has. Our distribution maintenance plans cover scheduled inspection, testing and servicing of your switchgear, panels and distribution equipment, with a written report after every visit, so problems are found on a planned visit instead of during a blackout.
submetering installation and commissioning
Accountability and sustainability go hand in hand. We install and commission multi-point electrical submeters for commercial buildings in Toronto and Etobicoke, so energy costs can be allocated fairly across tenants or departments and you can see exactly where your building uses power. Knowing is the first step to saving.

The wider GTA
Beyond the two core cities
Mississauga, North York, Vaughan, Richmond Hill and Oakville commercial properties, from single units to full buildings.
Which areas do you cover for commercial electrical work?
Our core is Toronto and Etobicoke, including the Rexdale and airport industrial belt, South Etobicoke, Leaside, the O’Connor and Bermondsey district and the Port Lands. We also serve Mississauga, North York, Vaughan and Richmond Hill. If your building is in the GTA, ask us.
Can you work outside our business hours?
Yes. Commercial work is scheduled around your operation: evenings, weekends and planned shutdowns where the job calls for it, so your business keeps running while the work gets done.
Do commercial electrical jobs need an ESA permit?
Most do. Commercial electrical work in Ontario requires an ESA notification and inspection, and we file the permit, do the work to the Ontario Electrical Safety Code, and close the inspection out for every job that needs one.
What is included in an electrical maintenance plan?
Scheduled inspection and testing of your distribution equipment, lighting and emergency systems, written reports after every visit, and priority response when something fails. The plan is built around your building, so you stay ahead of failures and regulations instead of reacting to them.
Can we add EV chargers without upgrading our electrical service?
Usually, yes. Load management shares the power you already have across every charger, so most properties add charging without a service upgrade. We assess your capacity first and tell you plainly which route your building needs.
How do we get a price for commercial work?
Send a request or call us. We visit the site, look at the actual work, and quote it in writing. No prices are guessed from a form, and the quote is the price you approve before we start.
We quote it. You approve it. We do it. ⚡
