200-Amp Panel Upgrade Cost in Ottawa: What Hydro Ottawa and ESA Add to Your Quote

A straightforward 100A-to-200A panel upgrade in Ottawa typically costs about $2,000 to $5,500, and that range usually includes the ESA inspection and Hydro Ottawa coordination. The panel itself is only one part of the project.

A straightforward 100A-to-200A upgrade can be relatively simple. But if the home’s existing service entrance, meter equipment, grounding, wiring, or utility connection also needs work, the total can increase quickly.

Upgrades from older 60-amp service, jobs that need the panel relocated and underground work cost more, at roughly $3,500 to $7,000 or more. The actual cost depends on what is already installed at the property and what the utility and electrician determine needs to change.

The important question is not simply:

“How much does a 200-amp panel cost?”

It is:

“What parts of my electrical service need to be upgraded to safely support 200 amps?”

That distinction can make a major difference to the final quote.

200-Amp Upgrade Cost in Ottawa at a Glance

Cost component	What it can include
Electrical contractor	Panel, breakers, labour, service equipment, grounding and related electrical work
Hydro Ottawa	Utility-side work or requirements identified through the service request and Customer Layout
ESA	Electrical notification, inspection and related regulatory requirements
Service entrance	Mast, meter base, conductors, conduit and other equipment, depending on the installation
Existing wiring	Repairs or upgrades if the existing installation has problems that affect the project
Additional electrical work	EV charger, heat pump, generator, hot tub, rewiring or other changes

A simple project usually lands in the $2,000 to $5,500 range. A project involving service-entrance work or other upgrades can be substantially higher.

Do You Actually Need 200 Amps?

This is the first question to answer before getting quotes.

A full panel does not automatically mean the house needs a 200-amp service.

Likewise, installing an EV charger, heat pump, hot tub or other large electrical load does not automatically mean a 200-amp upgrade is required.

What matters is the home’s service capacity and calculated electrical load, along with the requirements of the equipment being added.

There is also an important difference between panel space and electrical service capacity.

For example, a 100-amp service can have a panel that is physically full. Installing a larger panel may provide more breaker spaces, but it does not turn a 100-amp service into a 200-amp service.

If your main concern is simply a lack of breaker spaces, ask your electrician whether a panel replacement, load calculation, or service upgrade is actually necessary.

What Does a 200-Amp Upgrade Actually Change?

A typical service upgrade involves more than removing the old panel and installing a larger one.

The electrical service can be thought of as a chain:

Utility distribution system → service entrance → meter equipment → main disconnect/panel → branch circuits

The exact arrangement varies by property, but a 200-amp upgrade may involve several points along that chain.

1. The Electrical Panel

This is the part homeowners usually notice first.

The contractor may replace the existing panel with a 200-amp panel and install new breakers as required.

The price depends on:

Panel manufacturer and model
Number and type of breakers
AFCI/GFCI requirements
Panel location
Accessibility
Existing wiring condition
Whether circuits need to be extended or reorganized
Whether additional electrical work is being done at the same time

The panel is often visible, but it is not necessarily the most expensive part of the project.

2. The Service Entrance

The service entrance connects the home’s electrical system to the utility supply.

Depending on the property, this can involve equipment such as:

Service conductors
Meter base
Mast or service head
Conduit
Grounding and bonding equipment
Other service equipment

If this equipment is suitable for the new service, the project may be relatively straightforward.

If it needs to be replaced or modified, the cost can increase.

3. The Meter and Utility Connection

This is where Hydro Ottawa becomes part of the process.

For a service change, your electrician may need to coordinate with Hydro Ottawa rather than simply replacing the panel independently.

Hydro Ottawa’s service-request process can result in a Customer Layout, which identifies utility work and applicable charges or requirements for the project. Hydro Ottawa asks for the service request three to four weeks before the project starts.

The Customer Layout is important because it helps establish what the utility expects to happen and what work or costs may apply.

Do not assume every property will have the same utility requirements.

What Does Hydro Ottawa Add to the Cost?

Hydro Ottawa and the electrician do not necessarily perform the same work.

The utility’s involvement depends on the property’s existing service and the proposed change.

A service request may identify work required on the utility side, customer-owned equipment, or both.

That is why a contractor should not simply tell you:

“The panel price is the whole price.”

The utility requirements need to be considered as part of the project.

Hydro Ottawa’s documentation also makes clear that ownership and responsibility for service equipment can depend on the specific installation. Components such as the meter base, service conductors and overhead equipment should therefore be confirmed rather than assumed.

Ask for the Hydro Ottawa paperwork

If Hydro Ottawa has issued a Customer Layout or other project documentation, ask to see it.

You want to know:

What work Hydro Ottawa is requiring
What work the homeowner is responsible for
Whether there are utility charges
Whether the existing service arrangement can support the proposed upgrade
Whether any site changes are required before the utility work

This is much more useful than relying on a generic internet price.

What Does ESA Add to the Cost?

Electrical work in Ontario is overseen by the Electrical Safety Authority (ESA).

For most electrical work, a notification of work must be filed with ESA before the work begins. ESA commonly refers to this as a “notification of work,” although many homeowners still call it an electrical permit.

For a service upgrade, the process can involve a service/connection inspection.

ESA explains that the service inspection can cover customer-owned service equipment and related wiring, and that the utility must wait for the appropriate authorization before energizing the service. The exact inspection process depends on the project.

ESA fees also change over time. Its current 2026 fee information states that wiring and licensing fees were increased by 1.9% effective April 1, 2026.

Under ESA’s 2026 residential fee guide, a service change costs $86 per service when a licensed contractor files the notification ($212 when a non-contractor files it), and the minimum notification fee is $92.

So when comparing quotes, look for the ESA notification and inspection costs rather than assuming they are included.

If a Licensed Electrical Contractor is doing the work, ESA says the contractor should file the notification and request the inspection. After the work passes the applicable review, ESA issues a Certificate of Acceptance to the person who filed the notification.

Ask for a copy of the ESA Certificate of Acceptance for your records.

Overhead vs. Underground Service

The type of service supplying your house can have a major effect on the project.

Overhead service

With overhead service, the electrical connection comes to the property through overhead conductors.

An upgrade may involve work around the service mast, meter equipment, conductors and other components.

The condition and configuration of the existing equipment matter.

Underground service

Underground service can involve additional considerations such as:

Underground conductors
Conduit
Trenching
Existing underground infrastructure
Property access
Required clearances
Restoration after excavation

An underground installation is therefore not automatically more expensive in every case, but it can introduce additional work that an overhead installation may not require.

Your electrician should identify these issues during the assessment rather than simply applying a generic “200-amp upgrade” price.

The Service Entrance Can Make or Break the Budget

This is one of the biggest reasons two Ottawa homes can receive very different quotes for what sounds like the same project.

Consider two houses:

House A

Existing 100A service
Suitable service entrance
Accessible panel
Good existing wiring
No major repairs required

The project may be relatively straightforward.

House B

Older service entrance
Equipment that needs replacement
Difficult panel location
Grounding work required
Older wiring that needs correction
Additional electrical loads being installed

Calling both jobs a “200-amp panel upgrade” hides the biggest difference between them.

The panel rating is only one part of the project.

What About Older Homes?

Older Ottawa homes deserve a closer inspection before the quote is finalized.

The electrician may find:

Older cable types
Deteriorated wiring
Ungrounded circuits
Previous electrical modifications
Improperly protected wiring
Outdated or damaged equipment
Grounding or bonding issues
Limited space for modern equipment

A service upgrade does not automatically mean the entire house must be rewired.

However, if the electrician identifies an existing condition that needs to be corrected for the proposed work to be completed safely and in compliance with the Ontario Electrical Safety Code, that work can affect the price.

Ask the contractor to separate required work from recommended improvements in the quote.

That distinction makes a quote much easier to understand.

What If You Are Adding an EV Charger?

An EV charger is a common reason homeowners start looking into a service upgrade.

But an EV charger does not automatically mean you need 200 amps.

The electrician should assess the home’s existing service and electrical load and determine what capacity is available.

Depending on the installation, the appropriate solution could involve:

Installing the charger on the existing service
Managing or limiting charging load
Making other electrical changes
Upgrading the electrical service

Do not pay for a service upgrade simply because an installer says “EV charger = 200 amps.”

Ask for the electrical-load reasoning behind the recommendation.

What About Heat Pumps, Hot Tubs and Generators?

The same principle applies to other major electrical loads.

Heat pumps

A heat pump can add significant electrical demand, depending on the equipment and existing heating system.

Hot tubs

Hot tubs can require dedicated electrical circuits and specific protection.

Generators

Generators can require transfer equipment and other electrical changes depending on the installation.

Multiple upgrades

If you are adding several major loads at once, it makes sense to have the electrician evaluate the whole system rather than pricing each project independently.

For example:

EV charger + heat pump + hot tub

may produce a very different electrical-load calculation from:

EV charger alone.

The goal should be to size the service for the home’s actual requirements rather than automatically choosing 200 amps because it sounds like the larger option.

What Should a 200-Amp Upgrade Quote Include?

A useful quote should tell you what you are actually buying.

Look for separate descriptions of:

200A panel
Main breaker
Breakers and required circuit protection
Labour
Service entrance work
Meter base work, if applicable
Grounding and bonding
Conduit or mast work, if applicable
ESA notification
ESA inspection-related costs
Hydro Ottawa coordination
Utility charges, if applicable
Repairs to existing wiring
Permit or administrative charges
Disposal of old equipment
Any required drywall or finishing work

You should also ask whether the quote includes:

Electrical isolation/reconnection
Temporary loss of power
Testing
Panel labelling
Cleanup
Final documentation

If something is excluded, it should be clearly identified.

Why One Contractor’s Quote May Be Higher

A higher quote does not automatically mean the contractor is charging more for the same work.

The scopes may be different.

For example, one contractor might quote only:

“Replace 100A panel with 200A panel.”

Another might include:

“Replace panel, upgrade service equipment, correct grounding, coordinate utility work, complete ESA notification and inspection, and replace damaged service conductors.”

Those are not equivalent jobs.

When comparing prices, compare scope, not just the bottom-line number.

A Practical Ottawa Budget

Here is what a 200-amp upgrade typically costs in Ottawa:

Scenario	Typical price
Straightforward 100A-to-200A upgrade	$2,000 to $4,000
100A-to-200A upgrade incl. ESA inspection and Hydro Ottawa coordination	$2,500 to $5,500
60A-to-200A upgrade	$3,500 to $7,000
Upgrade with panel relocation	$5,000 to $6,000
Underground cable upgrade	$5,000 to $7,000+
ESA service change notification (contractor-filed)	$92 minimum

Once service-entrance replacement, underground work, extensive wiring repairs or additional electrical projects are involved, the final price moves toward the top of these ranges or beyond.

The property’s existing electrical infrastructure is what ultimately determines the quote.

How Long Does the Process Take?

Do not assume that the electrician’s installation time is the same as the total project timeline.

Utility coordination can happen before the installation, and ESA inspection/authorization requirements can affect when the service can be energized.

Hydro Ottawa asks for service requests to be submitted three to four weeks before the project starts.

ESA also explains that a service upgrade requires the appropriate inspection and authorization before the utility restores power.

Your electrician should be able to explain:

When the utility request will be submitted
What Hydro Ottawa needs to do
When the electrical work will take place
When ESA inspection is expected
When power can be restored
Whether the project requires more than one visit

The actual installation may take only part of a day in a straightforward case, but the overall project should be planned around utility and inspection coordination.

What to Do Before the Upgrade

Before installation day:

1. Confirm what is being upgraded

Ask whether the project is:

Panel-only
Panel plus service equipment
A complete service upgrade

2. Ask whether 200 amps is actually required

Request the load calculation or explanation supporting the recommendation.

3. Review the Hydro Ottawa requirements

Ask for the Customer Layout or other utility documentation when applicable.

4. Confirm ESA costs

Make sure the quote states whether the ESA notification and inspection-related costs are included.

5. Ask about existing wiring

Find out whether the contractor identified any deficiencies that need to be corrected.

6. Ask what is excluded

This is particularly important for drywall repair, trenching, utility charges and additional wiring.

7. Confirm the outage

Find out how long the house will be without power and whether you need to make arrangements for sensitive equipment, heating, cooling or other essential systems.

Questions to Ask Before Signing the Quote

Use these questions with any Ottawa electrician quoting a service upgrade:

Do I actually need 200 amps?
What is my current service capacity?
What does the load calculation show?
Does the existing service entrance support the upgrade?
Does the meter equipment need to be replaced?
What does Hydro Ottawa need to do?
Are there Hydro Ottawa charges, and are they included?
Is the ESA notification included?
Is the ESA inspection included?
Will you provide the ESA Certificate of Acceptance?
Are any existing wiring problems included in this price?
What work is specifically excluded?
Does the quote include grounding and bonding work?
Will the panel be fully labelled?
How long will the power be off?
What happens if additional problems are discovered after the panel is opened?

A contractor who can answer these questions clearly is giving you a much more useful quote than one that provides only a single number.

Red Flags in a 200-Amp Upgrade Quote

Be cautious if a quote:

Gives only a lump-sum price with no scope
Does not identify the panel or service equipment
Says a 200A upgrade is required without explaining why
Does not mention utility coordination
Ignores the service entrance
Does not address ESA requirements
Includes vague “code upgrades” without explaining them
Does not identify exclusions
Gives an unusually low price without explaining what is omitted

The cheapest number is not necessarily the cheapest completed project if major components are excluded.

Frequently Asked Questions

How much does a 200-amp panel upgrade cost in Ottawa?

A straightforward 100A-to-200A upgrade in Ottawa runs about $2,000 to $5,500, including the ESA inspection and Hydro Ottawa coordination. Upgrades from 60-amp service, panel relocations and underground work can run $3,500 to $7,000 or more.

There is no fixed Ottawa price. The actual quote depends on the existing service entrance, panel location, wiring, utility requirements and any additional electrical work.

Does a 200-amp panel mean I have a 200-amp service?

No.

The panel rating and the electrical service capacity are related but not identical concepts. A 200A-rated panel does not by itself upgrade a 100A service.

Does an EV charger require a 200-amp service?

Not automatically.

The home’s existing capacity and calculated electrical load should be evaluated first.

Does a full breaker panel mean I need a service upgrade?

Not necessarily.

You may simply need more breaker spaces or a different panel configuration. Have an electrician determine whether the service capacity itself is insufficient.

Do I need ESA approval for a service upgrade?

Electrical work generally requires a notification of work with ESA, and service upgrades involve inspection and utility coordination. ESA states that the utility needs the appropriate authorization before restoring power after a service inspection.

Does Hydro Ottawa charge for a service upgrade?

Potential utility charges depend on the project and the work required. The Customer Layout or other utility documentation should identify applicable requirements and costs. Each property gets one free Customer Layout per rolling 12-month period, but extra charges can apply if more work is needed, the site is not ready when a crew arrives, or the layout is revised.

Do not assume every 200-amp upgrade has the same Hydro Ottawa charge.

How long does a 200-amp upgrade take?

The physical electrical work may be completed relatively quickly in a straightforward installation, but the overall project can take longer because of utility coordination and ESA requirements.

Plan the project around the full process, not just the hours the electrician spends at the panel.

Should I upgrade to 200 amps if I am renovating?

Not automatically.

A renovation is a good time to have the home’s electrical load and future requirements evaluated, particularly if you are adding major loads such as an EV charger, heat pump, electric heating or other equipment.

Should I get more than one quote?

Yes.

But compare the scope of work, not just the price.

A $3,000 quote and a $4,000 quote may not represent the same project.

The Bottom Line

A 200-amp upgrade in Ottawa is not simply a matter of buying a bigger electrical panel.

The real project can involve:

Panel + service entrance + utility coordination + ESA requirements + grounding + existing wiring + additional electrical loads.

Expect roughly $2,000 to $5,500 for a straightforward 100A-to-200A upgrade in Ottawa, but your home’s existing electrical infrastructure determines the actual price.

Before approving the work, make sure the contractor explains:

Why 200 amps is needed
What equipment is being replaced
What Hydro Ottawa is responsible for
What you are responsible for
What ESA requires
What is included in the quote
What is excluded
What could increase the price

That is the difference between comparing two numbers and actually comparing two electrical projects.
