Electrical work in Toronto
Older homes need a careful electrician
Toronto has a lot of older housing. Semis and detached homes in neighbourhoods like the Annex, Leslieville, Riverdale, Roncesvalles and Forest Hill were often built before 1950, and some still have knob-and-tube or early wiring hidden behind plaster. Many insurers now ask about the wiring and the panel before they'll cover an older home.
Working in these houses means planning routes that don't wreck original plaster and trim, upgrading the panel and service to 200 amps, and bringing circuits up to code so you can add modern loads safely. One of our customers summed it up: after completion, "it was like they never had to run electrical conduits and cables throughout my house."
Condos and narrow lots
Downtown and midtown condo work, like pot lights, new circuits and lighting upgrades, needs coordination with property management and building rules. On narrow Toronto lots, EV chargers often go on a laneway garage or a front-pad parking spot, and the circuit run takes some planning. We sort that out at the first visit.
Toronto Hydro and ESA
Toronto Hydro supplies the whole City of Toronto. For service upgrades we book the disconnect and reconnect, file the ESA permit, and make sure you get the Certificate of Acceptance at the end.

Questions
Toronto electrical questions
Do you take out the ESA permit?
Yes. In Ontario, the licensed contractor files the notification of work with the Electrical Safety Authority (ESA) and books the inspection. We handle it on every job that needs one, and you get the ESA Certificate of Acceptance when the work passes. Keep it: insurers and home buyers often ask for it.
How much does a panel upgrade cost?
It depends on the house. The biggest factor is whether the hydro service to your house is overhead or underground, followed by where the meter and panel sit and how much wiring needs to move. The utility matters too: Toronto Hydro charges a fee for the disconnect and reconnect, which Alectra and Hydro One customers usually don't pay. Send us photos of your panel and meter for a first idea, and we give you a fixed written quote after a site visit.
Do I need a panel upgrade for an EV charger?
Not always. A Level 2 charger needs its own 240-volt circuit, usually 40 to 60 amps. We do a load calculation on your home first. If your panel has room, we install the charger on its own circuit. If it doesn't, the options are a panel or service upgrade, or in some homes a load management device that lets the charger share capacity. We'll tell you which applies.
Do you offer 24/7 emergency service?
Yes. For an electrical emergency call (647) 930-2907 any time, day or night. If you see smoke or fire, leave the house and call 911 first. If a power line is down, stay well back and call your hydro utility's emergency line.
