Panel & service upgrades
Electrical Panel Upgrades in Toronto & the GTA
From 100-amp fuse boxes to 200- and 400-amp breaker panels — upgraded safely, permitted and inspected to ESA code by a licensed master electrician.
Your panel is the heart of your home's electrical system — and on a lot of GTA homes it's the oldest part. If yours is a 60- or 100-amp fuse box, or a crowded panel with no room left for another breaker, it's quietly limiting what your home can do and, in some cases, creating a safety and insurance problem.
Kiyan Electric upgrades panels and services across Toronto, Richmond Hill, Vaughan, Markham and the wider GTA. We handle the whole job — permit, utility coordination, the new panel and the ESA inspection — so you get modern, code-compliant power without the runaround.
Signs it's time to upgrade
- Fuses blow or breakers trip when you run the microwave, A/C and kettle together
- You're adding an EV charger, central air, a hot tub or a home addition
- You still have a fuse box, or aluminum wiring, and your insurer is asking questions
- Flickering lights, a warm or buzzing panel, or scorch marks around breakers
- Not enough circuits — power bars and extension cords everywhere
If any of those sound familiar, book a free assessment. Sometimes the answer is a full upgrade; sometimes it's a sub-panel or a few new circuits. We'll tell you straight.
What we upgrade
100A, 200A, 400A — sized to your home
200-amp service upgrades
The GTA standard for a modern home. Enough capacity for an EV charger, central air, an electric range and a finished basement — with breakers to spare.
400-amp & sub-panels
For large homes, workshops, multi-unit and light commercial. We install main 400A services and sub-panels for garages, additions and dedicated equipment.
Fuse-to-breaker conversions
Retire the old fuse box for a modern breaker panel — safer, easier to live with, and the answer to most insurance requests on older GTA homes.
Questions we hear a lot
Electrical Panel Upgrades: your questions, answered
Do I need an ESA permit to upgrade my panel?
Yes. In Ontario, replacing or upgrading an electrical panel or service requires an ESA permit and a final inspection. Kiyan Electric pulls the permit, coordinates the utility disconnect and reconnect, and handles the ESA inspection sign-off for you.
How much does a panel upgrade cost?
It depends on the amperage, whether the meter base and mast need work, and the condition of your existing wiring. That's why the estimate is free and given upfront — a licensed electrician looks at your setup and quotes the real number before any work starts.
How long does it take?
Most residential panel upgrades are completed in a single day once the permit and utility disconnect are scheduled. Larger 400-amp or commercial services can take longer; we'll give you an accurate timeline with your estimate.
What's the difference between a fuse box and a breaker panel?
A fuse box uses screw-in fuses that have to be replaced when they blow; a modern breaker panel uses resettable breakers and supports more circuits, GFCI/AFCI protection and higher loads. Converting a fuse box to a breaker panel is one of our most common jobs — and insurers increasingly ask for it.
Will a panel upgrade let me add an EV charger or A/C?
That's often the reason people upgrade. Going from 100A to 200A frees up capacity for an EV charger, central air, a hot tub or a home addition. We size the new panel around what you're planning to add.
