Panel & service upgrades in Toronto & the GTA
100A to 200A upgrades, subpanels for basements and additions, and 400A–600A services for custom homes — sized properly, permitted with ESA and coordinated with your utility.
What’s included
Everything from load calculation to inspection.
Load calculation
We size the service for today and for what’s coming — EV charger, heat pump, hot tub.
Panel & breakers
New main panel, breakers, grounding and bonding, labelled circuits.
Subpanels
Basements, additions, garages and second floors.
Meter & service entrance
Meter base, mast or underground service work.
ESA permit & inspection
We file the notification and book the inspection.
Utility coordination
Disconnect and reconnect scheduled with your local hydro.
Who it’s for
The right upgrade for every project.
Homeowners, builders and property managers each need something different from a service upgrade.
Homeowners
Breakers tripping, an old fuse or 100A panel, or planning an EV charger or renovation.
Builders & GCs
200A–600A services on new custom homes, temporary construction power and subpanel layouts from your drawings.
Commercial & multi-unit
Three-phase panels, transformers, multi-meter bases and multi-site upgrade programs.

Questions
Panel upgrade FAQ
How much does a panel upgrade cost?
It depends on your existing service, panel location and utility requirements. We give a fixed, itemized quote after a site visit.
How long will my power be off?
Usually part of one day while the utility disconnects and reconnects the service. We schedule it with you in advance. Timing depends on the project.
Do I need a permit?
Yes. Service upgrades in Ontario require an ESA notification and inspection. As a licensed contractor (#7013769) we handle both.
Should I upgrade before installing an EV charger?
Often, but not always. We run a load calculation first — sometimes a load-management device avoids a full upgrade.
