Photo of your panel = a price by tomorrow
Half the people who call Panel Upgrade Kitchener about a flagged panel end up asking a second question: while the panel's out, should the service grow too? This page is the honest version of that answer — what a 200-amp upgrade physically involves, which loads force the issue, and when 100 amps genuinely remains enough.
The hardware
A service upgrade is not a bigger panel with the same plumbing behind it. Between the utility's wires and your breakers sits a chain of equipment sized for 100 amps, and the whole chain gets renewed:
The local utility — Enova Power across Kitchener, Waterloo and the townships, GrandBridge Energy in Cambridge — disconnects before the work and reconnects after ESA has looked at it. That utility appointment plus the ESA notification are fixed overheads, which is the entire economic argument for bundling: they're already on the invoice when a Stab-Lok swap is the reason for the visit.
The load math
The Level 2 EV charger is the usual trigger — a continuous draw larger than most ranges, arriving in a driveway near you on a lease you've already signed. The cold-climate heat pump is the second: swap a gas furnace for electric heating and the winter load profile of the house changes category. The accessory suite is the third and the most Kitchener-specific — provincial and municipal rules now welcome additional units in existing houses, and a second kitchen plus laundry lands hard on a 100-amp calculation.
Any one of these might squeak past on a given house. Two of them rarely do. The Ontario Electrical Safety Code load calculation settles it house by house, and the partner electrician runs it as part of quoting — if the answer is "100 amps still works for you," that's the answer you'll get in writing.
Rule of thumb that survives scrutiny: if the panel is being replaced anyway and any electrification plan exists for the next decade, the incremental cost of 200 amps today is the cheapest that capacity will ever be. The bundled ranges are on the cost page.
Sequence
ESA notification filed; disconnect booked with Enova Power or GrandBridge; materials confirmed against the quote.
Utility disconnects. Old mast, meter base and panel come off; new service hardware goes up.
New 200-amp panel wired, every circuit landed and labelled, grounding brought to code.
ESA inspects, utility reconnects, and the certificate follows — to your broker if a flagged panel started all this, to your records either way.
Questions
By calculation, not vibes. A licensed electrician runs the Ontario Electrical Safety Code load calculation for your actual square footage, heating type and appliances. Plenty of gas-heated Kitchener houses live happily on 100 amps — until an EV charger or a heat pump enters the plan, at which point the calculation frequently tips.
More than the panel: the service conductors from the utility connection point, the mast and meter base, the grounding system, and the main breaker all get renewed and upsized, and Enova Power (or GrandBridge Energy in Cambridge) performs a disconnect and reconnect around the work. That's why doing it alongside a panel swap is so much cheaper than doing it after one.
No. You pay for the energy you use, not the capacity available. A 200-amp service just stops capacity from being the reason you can't add the charger, the heat pump or the basement kitchen.
Sometimes — load-management devices can shed the charger when the house peaks, and some houses have calculation headroom. It's worth pricing both routes. But if your panel is a flagged brand headed for replacement anyway, the bundled upgrade usually beats charger workarounds on both cost and future flexibility.
Mention the charger, the heat pump or the suite plan — the load calculation shapes the quote.
One visit, one permit, one utility booking — and the house is ready for whatever you electrify next.
