We've worked with businesses through every stage of this decision. Here are the problems our commercial clients call us about most often.
A grid outage with no backup power means lost sales, spoiled inventory, or a full shutdown until utility service returns. Every hour without power adds directly to the cost of the disruption. We install standby systems that switch on automatically within seconds of an outage.
Guessing at generator size leads to either an underpowered unit that trips under load or an oversized system that costs far more than necessary. Both mistakes are expensive to correct after installation. We run a full electrical load assessment before recommending any generator capacity.
A sudden power loss can corrupt data, damage equipment, or take down business-critical systems without warning. Standard UPS battery backup only bridges a short gap before it runs out. We design generator systems that cover server rooms and IT infrastructure through extended outages.
Restaurants, grocery, and cold storage facilities can lose an entire inventory within hours of a power failure. That kind of loss often costs more than the generator itself would have. We size systems specifically to carry refrigeration loads without interruption.
A standby generator that fails to start during an actual outage is usually the result of skipped maintenance or a battery, fuel, or transfer switch issue that went unnoticed. Finding out during an emergency is the worst possible time. We service and test existing units, or replace generators that have reached the end of their reliable life.
Commercial generator installations require electrical permits and, for gas-fired units, a separate gas permit and inspection before commissioning. Missing a step can delay activation or fail an inspection outright. We manage the full permit and inspection process from submission to sign-off.
Clinics, medical offices, and facilities with life safety systems cannot treat backup power as optional, since equipment failure during an outage carries real risk. Code often requires a dedicated emergency power system for these applications. We design and install systems that meet the specific power continuity requirements of medical and life safety equipment.
Property managers overseeing multi-tenant buildings often face the choice between one shared standby system or dedicated units per tenant, and the wrong call affects both cost and reliability. Common area systems like elevators and emergency lighting have their own code requirements. We assess the building's layout and tenant needs before recommending a configuration.
Older commercial panels are sometimes undersized or outdated for the additional load a standby generator and transfer switch require. Installing a generator without addressing this first risks an unsafe or non-compliant setup. We evaluate the existing panel and recommend an upgrade if the generator installation requires one.
We lost power for almost six hours last winter and our walk-in cooler stayed running the whole time thanks to the generator Electrical Services Ontario installed. The automatic transfer switch kicked in within seconds. No spoiled inventory, no lost service on a Saturday night.
The team ran a full load assessment on our office building before quoting anything, and it turned out our original generator size request would have been undersized for our server room. Glad they caught that instead of just installing what we asked for.
The actual installation work went smoothly and the crew from Electrical Services Ontario was on site exactly when promised. The city permit approval took longer than expected which pushed our start date back about a week, but that was outside their control and they kept us updated the whole time.
I called expecting to need a much larger unit than we ended up getting. Electrical Services Ontario explained our critical circuits only required a mid-sized generator, which saved us thousands compared to the oversized system another company quoted.
We didn't want to deal with coordinating a separate gas contractor and inspector, and this company managed the entire process from permit to final commissioning. The generator passed inspection on the first attempt and has run flawlessly since.
Our previous standby generator failed to start during an outage and we needed a replacement fast. The crew assessed our building, sized a new unit correctly, and had it operational within four days. Our operations manager has not stopped talking about how smooth it went.

Tell us what is happening — no power, a breaker that will not reset, or a planned upgrade. We talk it through and book a time that works for you, including same-day for urgent calls.
A licensed electrician looks at the actual panel, circuit, and load rather than quoting over the phone, then gives you a firm written price with the scope set out line by line.
The electrician who quoted the job does the work. Drop sheets go down, permits are filed where the work calls for it, and you get an update before anything changes from the plan.
Every circuit is tested before we close the panel, the inspection is booked and the certificate handed over, and our labour is warrantied for two years.
