Eight triggers account for almost every panel upgrade we quote in Vaughan. If one of these describes your property, the load calculation will tell you how far the existing service can stretch. 01 ### Home insurance refusal or a renewal notice Toronto underwriters decline or surcharge policies on homes still running an obsolete 60A service or a fuse block. The ESA Certificate of Inspection is what closes the file. 02 ### Level 2 EV charger installation at 40A or 50A An EV charger is a continuous load. Added to laundry, HVAC and refrigeration on an aged 100A panel, the OESC Section 8 calculation runs out of room fast. 03 ### Heat pump or central air conversion Moving off gas heating to a cold-climate heat pump needs dedicated high-amperage breakers and headroom the original panel was never sized for. 04 ### Legal basement suite or accessory dwelling unit City of Toronto secondary-suite permits require a documented load calculation, a dedicated subpanel and a separate disconnect for the suite. 05 ### Screw-in glass fuses or cartridge fuse blocks Fuse blocks cannot provide the arc-fault and ground-fault protection the Ontario Electrical Safety Code now expects on modern branch circuits. 06 ### Flickering lights when appliances start That flicker is voltage drop under load. It points at bus-bar saturation or loose terminations at the main breaker, both end-of-life signals. 07 ### Doubled-up breakers with no knockouts left When every position is tandemmed and the enclosure has no knockouts left, adding a circuit safely means a new load centre, not more stacking. 08 ### Corroded service mast or meter base A weathered mast and weatherhead lets water track into the panel interior. The service entrance conductors and meter base get replaced with the panel. ## Panel Upgrade Services in Vaughan Vaughan panel work covers large-home 200A upgrades and 400A services for oversized residential and commercial buildings, coordinated with Alectra Utilities. Alectra Utilities handles the disconnect and reconnect for Vaughan addresses. We file the ESA Notification of Work, book the utility window, complete the install, and hand over the Certificate of Inspection. ![Crew installing a 200A main breaker and 42-circuit load centre in a Toronto basement](/images/misc/two-electricians-in-plain-navy-workwear-seen-from-.webp) Most Requested ### 100A to 200A Service Upgrades Upgrade an undersized 100A service to a 200A, 42-circuit panel with Toronto Hydro disconnect and reconnect coordinated on the day.

Morning slots let us finish and re-energize inside the same working day. 3. 03 ### Meter pull and service change The utility pulls the meter and drops the service. We replace the meter base, service entrance conductors, mast or lateral, and the load centre. 4. 04 ### ESA inspection The ESA inspector attends, reviews bonding, grounding, terminations and labelling, and signs off the Certificate of Inspection. 5. 05 ### Energization and handoff The utility reconnects and sets the meter. You get the certificate, the panel schedule and the itemised invoice matching the original quote. ## Booking a panel upgrade in Vaughan?

Alectra Utilities handles the disconnect and reconnect, and 400A services need the CT cabinet arrangement confirmed with them before install. ## Vaughan Housing Stock We Work On Woodbridge and Maple hold large modern detached homes where the demand calculation often points to 400A with twin 200A panels rather than a single 200A service. Older Thornhill streets carry 100A services and 1970s panels that need full replacement. ## Vaughan Housing Stock and Seasonal Notes Vaughan is the part of the GTA where we most often size a residential service at 400A rather than 200A. Large modern detached homes in Woodbridge, Maple and Kleinburg combine two EV chargers, a pool heater, electric radiant heat and a secondary kitchen, and the demand calculation simply exceeds what a single 200A service can supply. The usual arrangement is a 400A service feeding twin 200A panels, and that needs a CT cabinet arrangement agreed with Alectra Utilities before equipment is ordered. Older Thornhill streets are a different job entirely: 100A services and 1970s panels with double-tapped terminals and no spare positions, where a straight panel replacement or a 200A upgrade is the answer. Pool season drives the spring rush. Homeowners want the pool heater and equipment circuits live for May, which means the panel work needs to happen in March or April. Booking a 400A service change in April for a May pool opening rarely leaves enough room for the utility window, so we push those conversations into the winter. ## Neighbourhoods We Cover in Vaughan - Woodbridge - Maple - Thornhill ![Finished 200A load centre with a labelled breaker schedule in a GTA basement](/images/features/detail-shot-of-a-finished-200a-load-centre-with-la.webp) ## Local service facts Distribution utility Alectra Utilities Municipality City of Vaughan Scheduling Same-Week Scheduling ESA permit Included Book a Free Estimate [/free-estimate/ →](/free-estimate/) View on Google Maps [https://www.google.com/maps/dir/?api=1&destination=43.8361,-79.4985 →](https://www.google.com/maps/dir/?api=1&destination=43.8361,-79.4985) ## What Vaughan Customers Say Panel upgrades and service entrance work in this area. > Large house, two EV chargers and a pool heater. They sized it at 400A with a CT cabinet instead of pretending 200A would cope. Gino P.Woodbridge > 1970s panel with double-tapped breakers and no free slots. The replacement went in clean and the ESA inspector signed it off the same week. Andrea L.Thornhill ## Panel Upgrade FAQs for Vaughan ### Do you cover Vaughan for panel upgrades? Yes. Vaughan is inside our GTA service radius, including Woodbridge, Maple, Thornhill, Kleinburg and Concord. ### Which utility handles a Vaughan panel upgrade? Alectra Utilities is the distribution utility for Vaughan. We coordinate the disconnect and reconnect with Alectra, including the CT cabinet arrangement on 400A services. ### When does a Vaughan home need 400A instead of 200A? When the OESC Section 8 demand calculation exceeds a 200A service, which happens on large homes combining multiple EV chargers, a pool, electric heating and a secondary kitchen. The usual arrangement is a 400A service feeding twin 200A panels. ### What does a panel upgrade cost in Vaughan? A 100A to 200A upgrade runs $2,500 to $8,000 CAD and a 200A to 400A upgrade $5,000 to $15,000 CAD, with the ESA permit fee and utility coordination fee itemised. ### What does a 400A residential service involve in Vaughan? A 400A service needs a CT cabinet for utility metering, service entrance conductors rated for 400A, and usually twin 200A panels rather than a single very large load centre. The CT cabinet arrangement has to be agreed with Alectra Utilities before equipment is ordered, which is the step that most often delays these projects when it is left late. ### Can you have pool equipment circuits ready for May? Yes, if the work is booked in late winter or early spring. Pool heater and equipment circuits are straightforward, but where the panel is full or the service needs upgrading first, the Alectra disconnect window becomes the constraint. A April booking for a May opening rarely leaves enough room on a service change. ### Still have a question? Ask the crew directly.
