Quick answer: A standard 100A to 200A electrical panel upgrade in Ottawa typically costs $2,000 to $5,000 in 2026, including the ESA notification and Hydro Ottawa coordination. A like-for-like panel replacement runs $1,500 to $3,000, and converting an old fuse box to a breaker panel typically runs $2,000 to $4,000.
How Much Does a Panel Upgrade Cost in Ottawa?
Most Ottawa homeowners pay between $2,000 and $5,000 to replace a 100A panel with a 200A panel. The final price depends on whether your existing service entrance (mast, meter base, and service cable) can carry the larger load, how far the panel sits from the meter, and how much of the existing wiring needs to be brought up to code.
Ottawa Panel Upgrade Cost Breakdown (2026)
| Job type | Typical Ottawa cost | What affects the price |
|---|---|---|
| Panel replacement at the same amperage | $1,500–$3,000 | Panel brand and size, number of breakers, condition of existing connections |
| 100 amp to 200 amp panel upgrade | $2,000–$5,000 | Whether the service entrance can carry 200A, panel location, ESA and Hydro Ottawa coordination |
| Fuse box to breaker panel conversion | $2,000–$4,000 | Number of circuits, age of wiring, whether the service is also upgraded |
| Additional wiring | $300–$1,000 per new circuit | 120V circuits run about $300–$800 and 240V circuits about $400–$1,000, depending on run length and wall access |
These are market benchmarks, not a fixed price list. Rewiring a whole home costs far more than adding circuits. Your exact quote depends on a site visit and a load calculation.
What Affects the Cost of a Panel Upgrade?
Four things move the price most: the condition of your service entrance, the location of the panel relative to the meter, the age of your existing wiring (older Ottawa homes with knob-and-tube or aluminum branch wiring cost more), and whether the electrician needs to open walls or finish drywall. A clean, same-location swap sits at the bottom of the range.
When Should You Upgrade Your Electrical Panel?
Upgrade your panel when it can no longer safely carry your home's electrical load. The most common triggers are:
- Breakers trip often or lights dim when large appliances turn on.
- You are adding an EV charger, heat pump, hot tub, or electric heating, which can push a 100A service past its limit.
- You still have a fuse box, or your panel is a recalled or outdated brand.
- There are no spare breaker spaces for new circuits.
- You are renovating a kitchen, basement, or addition that needs new circuits.
If any of these apply, have a licensed electrician run a load calculation to confirm whether you need a full upgrade. For help choosing the right size, read our guide to 100 amp vs 200 amp panels.
Frequently Asked Questions About Panel Upgrade Costs in Ottawa
How much does a 200 amp panel upgrade cost in Ottawa?
Typically $2,000 to $5,000 for a standard 100A to 200A swap in 2026. A like-for-like replacement at the same amperage runs $1,500 to $3,000, and a fuse box to breaker panel conversion typically runs $2,000 to $4,000.
How long does a panel upgrade take?
The installation itself usually takes one day, with power off for roughly 6 to 10 hours. Allow additional time beforehand for the Hydro Ottawa and ESA coordination.
Do I need an ESA permit for a panel upgrade?
Yes. Your licensed electrician files the ESA notification before work starts. The 2026 fee is $86 for a service or panel change filed by a contractor, with a $92 minimum notification fee. Check the current ESA fees.
Does Hydro Ottawa need to be involved?
When your service entrance or meter base changes, Hydro Ottawa disconnects and reconnects power after the ESA inspection passes. Your electrician coordinates this.
Is there a rebate for upgrading my electrical panel in Ontario?
Ontario's Home Renovation Savings program does not list panel upgrades as an eligible measure, but panel work may be required to install eligible upgrades such as a heat pump. Confirm eligibility on the program site before starting.
Do I need a panel upgrade to install an EV charger?
Not always. If your panel has spare capacity, a Level 2 charger can go in without one. A load-management device ($300 to $700) is sometimes an alternative. A load calculation decides.
Should I upgrade to 200 amps or 100 amps?
Most Ottawa homes adding electric heating, a heat pump, or an EV charger are better served by 200A. See our 100 amp vs 200 amp comparison.
