What Does a Panel Upgrade Cost in Ontario — And Is It Worth It?
Let's Talk About The Cost Honestly
If you've been putting off a panel upgrade because of the cost, you're not alone. It's one of the most common reasons homeowners delay — and one of the most expensive mistakes they make in the long run.
Fuse-to-breaker panel replacements start from approximately $2,000, while a full service upgrade from 100A to 200A starts from $3,200. Both figures include labour, materials, ESA permit, Hydro One coordination where required, and taxes. The total cost depends on the type of panel, the breakers required, and whether any rewiring is needed as part of the job. No hidden fees, no surprises.
The only way to know exactly where your job falls is an on-site inspection — which is exactly why we offer one.

What Makes Up the Cost of a Panel Upgrade?
Understanding where the money goes makes the investment easier to evaluate.
Materials
The panel itself is the single largest cost in any upgrade. A quality residential breaker panel, breakers, wiring components, and associated hardware make up the bulk of the overall price. The type of panel required, the breakers specified, and whether any rewiring is needed are the primary factors that determine where your job lands in the pricing range. We don't cut corners on materials — the equipment we install is built to last and meets Ontario's electrical safety standards.
ESA Permit & Inspection
All panel upgrade work in Ontario legally requires an ESA permit. This isn't optional — it's what ensures the work is inspected, documented, and legally compliant. We handle the permit filing and coordinate the ESA inspection on your behalf so you don't have to navigate that process yourself.
Labour
A panel upgrade is typically a full day's work for a licensed electrician. It involves safely disconnecting your existing panel, installing the new one, reconnecting all circuits, and ensuring everything is correctly labelled and functioning before we leave. If rewiring is identified as necessary during the inspection, that work is factored into the final quote upfront — not added after.
Hydro One Coordination
For service upgrades, Hydro One must disconnect and reconnect your meter before and after the installation. Coordinating this correctly affects when the work can actually be scheduled. We manage that coordination directly — something not every contractor handles for you.
Two Common Scenarios — And What They Typically Cost
Fuse Box to Breaker Panel Replacement
If your home still has a fuse box and you're upgrading to a modern breaker panel at the same amperage, this is generally the more straightforward of the two jobs. Pricing for this type of work starts from $2,000 and depends on the panel type and any additional wiring requirements identified during an electrical inspection.
100A to 200A Service Upgrade
Increasing your home's electrical capacity from 100 amps to 200 amps is a more involved job that requires Hydro One coordination and a higher-capacity panel and breakers. This type of upgrade starts at $3,200. It's the right solution for homes that need more capacity for brand new appliances, EV chargers, air conditioning, or renovations.
Not sure which one applies to your home? That's exactly what the inspection determines.
The Real Cost of Doing Nothing
This is where the math gets uncomfortable.
Insurance Risk
Insurance companies increasingly flag older fuse panels and undersized electrical services as a liability. Some homeowners discover this when renewing their policy, after purchasing a new appliance, or when making changes to their home that prompt a closer look at the electrical system. In some cases, insurers require upgrades as a condition of continued coverage. Addressing this proactively on your terms is far less stressful than being forced into it.
Fire Hazard
Outdated panels — particularly fuse boxes and certain older breaker panels — are a known fire risk. Overloaded circuits, improper fuse replacements, and panels that can't handle modern electrical demands create conditions that responsible homeowners shouldn't ignore indefinitely.
You Can't Renovate or Add Capacity
Planning a kitchen renovation, finishing a basement, adding an EV charger, or installing air conditioning? In most cases, none of these are possible without an adequate panel. Putting off the upgrade doesn't just delay the safety fix — it delays everything else you want to do with your home.
Ongoing Nuisance Costs
Frequently blown fuses, tripping breakers, and the limitations of working around an inadequate electrical system add up over time — in frustration, in workarounds, and occasionally in damage to appliances and electronics running on unstable power.
Why a Licensed Electrician — Not a Shortcut
There are cheaper ways to approach electrical work. There are unlicensed contractors, DIY videos, and people willing to do the job without pulling permits. Here's why none of those are worth the risk.
-
If electrical work is done without an ESA permit and something goes wrong — a fire, an injury, a failed home inspection — you are liable. Unpermitted work can void your home insurance, complicate a future sale, and leave you personally responsible for consequences that a proper permit would have covered.
-
Ontario's Electrical Safety Authority licensing requirements aren't bureaucratic red tape — they're the standard that ensures the person working on your home's electrical system has demonstrated the knowledge to do it safely. Eldridge Electric holds ECRA/ESA licence #7015512. That number is verifiable, and it means every job we do is done to a documented standard.
How Our Payment Process Works
We ask for 50% upfront to begin securing materials and confirm your commitment to the project. The remaining 50% is due upon completion. This structure exists because quality materials need to be ordered and held specifically for your job — and it ensures both parties are serious about seeing the project through.
There are no hidden fees added at the end. The price we quote after your inspection is the price you pay.
-
A panel upgrade done correctly should last decades without issues. Cutting corners on materials, skipping permits, or hiring someone without the right credentials often means the work needs to be redone — at full cost — sooner than it should.
