Updated for 2026. Vaughan is home to two of the busiest categories on my calendar: custom-built estates that need serious load planning from day one, and older Woodbridge and Thornhill pockets where knob-and-tube wiring and 100-amp panels still surprise owners. A 200-amp service upgrade now runs $3,500–$5,500 in Vaughan's larger homes.
Two Vaughans, two electrical realities
Woodbridge's older streets and the Thornhill side of Vaughan hold 1950s–1970s homes — solid brick, mature lots, and wiring from an era of one television and a toaster. Many have knob-and-tube in the walls, 100-amp service and panels that have never met a Level 2 charger. Meanwhile the new Vaughan — Kleinburg's estate lots, the custom builds off Highway 27, Vellore Village and the Maples infill — is building 4,000–10,000 sq ft homes with theatres, pools, saunas, outdoor kitchens and two EVs. I price both every week, and they could not be more different jobs.
Older pockets: knob-and-tube and undersized services
The older-stock calls come in waves. Homeowners find cloth-insulated wiring in an attic during a reno, an insurer flags knob-and-tube at renewal, or a panel simply has no room for the induction range they just ordered. Knob-and-tube has no ground conductor and its insulation degrades with age and insulation-contact, so the honest options are removal or, in rare selective cases, a documented insurance-accepted strategy — our knob and tube replacement work is scoped room by room with an ESA inspection at the end. Budget $8,000–$18,000 for a full removal on a typical two-storey, less when walls are already open.
Service upgrades: 200 amps is the new normal
Twenty years ago, 100-amp service carried most GTA homes. Vaughan killed that era faster than anywhere — larger floor plates, electric everything, and garages that hold two EVs. Today roughly four out of five of the service upgrades we install in the Vaughan area go straight to 200 amps, and new custom builds rarely spec less than 200A with a 40-space panel. The warning signs I hear about are always the same: the breaker that trips when the dryer and range run together, lights dimming at the air handler, a hot summer panel.
A panel and service upgrade in Vaughan typically runs $3,500–$5,500 installed and permitted — more when Alectra's connection requirements add hardware, which we handle as part of the job.
If you are unsure where you stand, the one-hour load calculation answers it. We run the numbers on your actual appliances, heating and plans — pool heaters, saunas and second EVs included — and tell you whether 200A covers it or a larger service makes sense. In Vaughan's bigger estates, 200A is occasionally not the ceiling, and it is better to learn that on paper than the first hot weekend.
Custom homes: load planning from day one
The expensive mistakes in custom builds are made on paper, long before wire is pulled. Load calculation, panel location and spare capacity, generator provisions, pre-wiring for solar and EV, dedicated appliance circuits, landscape and pool power — all of it is cheap at the drawing stage and brutally expensive after drywall. A proper custom home electrical plan also sequences with the builder so inspections never hold the build. If you are planning an estate in Kleinburg or a custom in Vaughan, involve your electrician at the permit drawings, not after the framing.
Two custom-build items homeowners forget until framing is done: generator provisions — a transfer switch location and panel space decided now costs almost nothing, and retrofitting one into a finished mechanical room later runs into thousands — and landscape power. Stone pillars, gate operators, pond equipment and pathway lighting all want conduits stubbed out before the grade is finished. The drawing stage is the only cheap moment for both.
Lighting design in high-end homes
Vaughan's luxury market has made lighting a real design trade, and I love that. Coffered ceilings with dimmable LED accents, crystal pendants over islands, layered cove lighting — the work I am proudest of in this city lives in ceilings like these. The technical rules do not change with the budget: IC-rated housings, matched dimmers and drivers, CRI 90+ for kitchens and anywhere food and faces matter, and lighting zones planned with the interior designer before the drywall stage. Done right, lighting is the single biggest visible return in a high-end build.
What common jobs cost in Vaughan in 2026
| Job | Typical range (installed, CAD) |
|---|---|
| Service upgrade to 200A (larger home) | $3,500 – $5,500 |
| Panel change, like-for-like 200A | $2,200 – $3,200 |
| EV charger circuit (Level 2) | $1,200 – $2,000 |
| Coffered-ceiling pot light package | $2,500 – $5,000 |
| Knob-and-tube removal, two-storey | $8,000 – $18,000 |
| Generator transfer equipment | $1,500 – $3,500 |
Access, ceiling detail and the condition of the existing service move every number on that table — which is why we walk the home before quoting anything in Vaughan or Richmond Hill.

Questions Vaughan homeowners ask me
My Woodbridge home has knob-and-tube. Is it dangerous?
Undisturbed, unloaded knob-and-tube is usually just outdated — the danger comes from decades of amateur taps, insulation buried over it, and overloaded circuits. Insurers still want it gone. Removal is a multi-day job with an ESA inspection, and it raises your home's value and insurability the day it is done.
Do I really need 200 amps for a 3,500 sq ft home?
With electric cooking, a pool, and one EV — yes, and with two EVs you will thank me. A load calculation takes the guesswork out, but I have never once regretted spec'ing 200A with a 40-space panel on a Vaughan custom build.
Can you wire a custom home while it is being built?
That is exactly when wiring should happen — rough-in before drywall, load planning at the drawing stage. We work directly with Vaughan builders and designers, and we book inspection slots so the build schedule never waits on us.
Why do my pot lights flicker on dimmers?
Almost always a fixture-dimmer mismatch or a non-LED-rated dimmer. In high-end homes it is worth doing once with quality matched components — Lutron pairings are my default — rather than living with flicker in a finished ceiling.
