A new kitchen can completely transform your home.

New cabinets, countertops, lighting, appliances, and an island may get most of the attention—but there's another part of the renovation that needs to be planned before the walls are closed:

The electrical system.

Modern kitchens use a tremendous amount of electrical equipment. Your refrigerator, microwave, dishwasher, range, countertop appliances, lighting, exhaust equipment, and specialty appliances all need to be considered when designing the electrical installation.

And in Ontario, kitchen electrical work must comply with the Ontario Electrical Safety Code (OESC).

If you're planning a kitchen renovation in Ottawa, here's what you should understand about outlets, circuits, GFCI protection, electrical panels, permits, inspections, and planning your new kitchen properly.

Why Kitchen Electrical Planning Matters

An older kitchen may have been designed when homeowners used far fewer electrical appliances.

Today, a typical kitchen could include:

• Refrigerator

• Electric or induction range

• Dishwasher

• Microwave

• Range hood

• Coffee maker

• Kettle

• Toaster

• Air fryer

• Blender

• Stand mixer

• Wine fridge

• Beverage centre

• Garbage disposal

• Under-cabinet lighting

• Island receptacles

• USB or charging outlets

Trying to run a modern kitchen on an electrical layout designed decades ago can create problems.

That's why a major kitchen renovation is often an excellent opportunity to evaluate the electrical system rather than simply moving existing outlets around.

1. Kitchen Countertops Need Properly Planned Receptacles

One of the most noticeable parts of a kitchen electrical renovation is receptacle placement.

Ontario has specific requirements governing receptacles serving kitchen counters, islands, peninsulas, and other areas.

ESA publishes detailed guidance explaining how kitchen receptacle requirements apply to different layouts, including open-concept kitchens.

The electrical layout therefore needs to be designed around the actual kitchen plan.

Your electrician should know where the following will be located:

• Countertops

• Sink

• Range

• Refrigerator

• Island

• Peninsula

• Pantry

• Built-in appliances

Changing the kitchen layout after the electrical rough-in can create unnecessary complications.

2. Don't Design the Kitchen First and Think About Outlets Later

This is a common renovation mistake.

The homeowner works with the kitchen designer, orders cabinetry and countertops, and only afterward asks:

"Where are we going to put the outlets?"

Electrical planning should happen earlier.

Your kitchen designer, general contractor, appliance supplier, and Licensed Electrical Contractor should ideally work from the same layout.

Before electrical rough-in begins, you should know where major appliances and work surfaces will be located.

3. Countertop Circuits Have Special Requirements

Kitchen countertop receptacles are different from ordinary receptacles elsewhere in the house.

They're expected to supply appliances that can draw significant power.

Think about what might be running simultaneously:

• Kettle

• Toaster

• Coffee machine

• Blender

• Air fryer

The Ontario Electrical Safety Code includes specific branch-circuit and receptacle requirements for kitchen countertop areas.

This is why you shouldn't simply extend whichever nearby circuit happens to be convenient.

A properly designed kitchen electrical system considers how the countertop will actually be used.

4. GFCI Protection Is an Important Part of Kitchen Safety

You've probably seen receptacles with TEST and RESET buttons.

These are Ground Fault Circuit Interrupters, commonly called GFCIs.

GFCI protection is designed to reduce the risk of electrical shock by quickly interrupting power when certain current leakage conditions are detected.

This is particularly important around areas where electricity and water may come together.

Ontario's electrical requirements include GFCI provisions affecting receptacles in applicable locations, including requirements related to kitchen installations. ESA also provides specific guidance for older split kitchen receptacles and how they can be upgraded to GFCI protection.

Exactly where and how GFCI protection is required depends on the installation.

Your Licensed Electrical Contractor can determine what applies to your renovated kitchen under the current Code.

5. AFCI Protection May Also Apply

GFCI and AFCI sound similar, but they serve different purposes.

GFCI protection primarily addresses certain electrical shock hazards.

AFCI, or Arc-Fault Circuit Interrupter protection, is intended to help protect against certain electrical arcing conditions that can contribute to fires.

Ontario's electrical requirements include AFCI protection for many residential receptacle branch circuits, with specific requirements and exceptions applying to kitchen circuits.

ESA's kitchen guidance specifically addresses which kitchen branch circuits require AFCI protection and which countertop, refrigerator, island, and peninsula circuits may fall under particular exceptions.

This is another reason renovating an older kitchen isn't necessarily as simple as reproducing the original electrical layout.

6. Your Refrigerator Needs to Be Considered Separately

Your refrigerator is one of the few appliances in your kitchen operating essentially all day, every day.

Ontario's kitchen electrical guidance includes specific provisions for refrigerator receptacles and branch circuits. ESA also provides clarification for additional refrigeration equipment such as freezers, mini-fridges, and beverage coolers.

If you're designing a kitchen with:

• Full-size refrigerator

• Separate freezer

• Wine cooler

• Beverage fridge

tell your electrician during the planning stage.

Don't assume they can all simply share whatever outlet happens to be nearby.

7. Your Dishwasher Needs Electrical Planning

A built-in dishwasher should be incorporated into the electrical design before cabinetry is installed.

Your electrician needs to know:

• Dishwasher location

• Manufacturer electrical specifications

• Cabinet layout

• Plumbing arrangement

• Connection method

• Circuit requirements

If you're relocating your dishwasher during the renovation, electrical changes may be necessary.

The same principle applies to other built-in appliances.

8. Microwave Ovens Can Require Special Attention

A modern microwave can draw a considerable amount of power.

Built-in microwaves, over-the-range microwaves, and microwave drawers may have different electrical requirements.

ESA's current kitchen guidance specifically identifies a dedicated microwave receptacle as an example of an additional kitchen receptacle whose branch circuit may be subject to AFCI requirements.

Before electrical work begins, provide your electrician with the specifications for the microwave you intend to install.

9. Electric and Induction Ranges Can Be Major Loads

If you're changing from gas cooking to an electric or induction range, tell your electrician as early as possible.

This can represent a significant new electrical load.

The electrical requirements depend on the appliance manufacturer's specifications and the existing installation.

Your electrician may need to evaluate:

• Existing range circuit

• Conductor size

• Breaker

• Receptacle or connection

• Electrical panel

• Overall service capacity

This becomes particularly important if you're electrifying several parts of your home at the same time.

For example, perhaps you're adding:

• An induction range

• EV charger

• Heat pump

• Electric water heater

• Hot tub

Taken together, those changes can significantly affect your home's electrical demand.

10. Your Electrical Panel Needs to Be Part of the Conversation

Kitchen renovation planning shouldn't stop at the kitchen walls.

Your electrical panel may also need to be evaluated.

An electrician may look at:

• Existing service capacity

• Available breaker spaces

• Panel condition

• Existing kitchen circuits

• New appliance loads

• Future electrical plans

Having empty spaces in the panel doesn't automatically mean you have unlimited electrical capacity.

Likewise, a full panel doesn't automatically mean you need a 200-amp service upgrade.

The actual electrical loads need to be considered.

11. Do You Need a 200-Amp Upgrade for a Kitchen Renovation?

Not automatically.

Even a substantial kitchen renovation doesn't necessarily require upgrading your home to 200-amp service.

It depends on:

• Your existing service

• Existing electrical loads

• New appliances

• Heating equipment

• EV charging

• Hot tubs or pools

• Other large loads

• Future plans

If you're switching several major appliances from gas to electricity, however, it's worth having your home's electrical capacity evaluated.

A proper load calculation can determine whether your existing service remains appropriate.

12. Kitchen Islands Need Electrical Planning Too

Kitchen islands have become one of the most popular features in modern renovations.

But they're not simply cabinets sitting in the middle of the room.

The electrical design may need to account for the island based on its configuration and use.

ESA publishes specific guidance addressing receptacle requirements for kitchen islands and peninsulas.

This needs to be considered before the finished flooring, island, and cabinetry are installed because wiring may need to be routed to the island location.

If your island will include appliances such as:

• Dishwasher

• Microwave

• Beverage refrigerator

• Cooktop

planning becomes even more important.

13. Don't Forget Under-Cabinet Lighting

Under-cabinet lighting can dramatically improve both the appearance and functionality of a kitchen.

It's also much easier to plan while the kitchen is being renovated.

Common options include:

• LED strip lighting

• Linear fixtures

• Integrated cabinet lighting

• Dimmable lighting

• Smart lighting

Think about where switches and controls should be located and whether you'd like separate control over task lighting and general kitchen lighting.

Planning the wiring before the backsplash and cabinetry are finished produces a much cleaner installation.

14. Think About Your Lighting Before Drywall Goes Up

A kitchen may use several layers of lighting:

General lighting

Pot lights or ceiling fixtures that illuminate the entire room.

Task lighting

Lighting over countertops and food-preparation areas.

Decorative lighting

Pendant lights above islands or dining areas.

Accent lighting

Cabinet, display, or architectural lighting.

A good kitchen electrical plan considers all four before the ceiling is finished.

If you want smart switches, dimmers, or automated lighting controls, discuss those during the rough-in stage too.

15. Older Ottawa Homes May Need More Electrical Work

Kitchen renovations in older Ottawa homes can uncover electrical systems that have been modified several times over the decades.

Once cabinets and walls are opened, you may discover:

• Older wiring

• Aluminum branch wiring

• Limited circuits

• Improper previous modifications

• Outdated devices

• Junction boxes

• Wiring that doesn't match the new layout

Don't automatically assume this means disaster.

But don't cover questionable electrical work back up without having it evaluated either.

A renovation provides an opportunity to correct problems while the wiring is accessible.

16. Be Careful With DIY Electrical Work

You may be comfortable painting walls, installing cabinet hardware, or assembling furniture.

Electrical work is different.

Improper connections can remain hidden behind walls for years before creating a problem.

Ontario's ESA states that when you hire someone to perform electrical work, that person or company must be a Licensed Electrical Contractor. A general contractor or handyperson cannot legally perform electrical work for hire unless appropriately licensed.

If your general contractor says:

"My guy handles the electrical."

Ask who the Licensed Electrical Contractor is and verify their ECRA/ESA licence.

17. Your Kitchen Renovation Will Usually Require an ESA Notification

This is something homeowners sometimes call an electrical "permit."

ESA states that almost all electrical work in Ontario requires a Notification of Work. Renovation work involving changes to original wiring, including many repairs and device replacements, falls within ESA's residential renovation process.

If you're hiring a Licensed Electrical Contractor, the contractor files the notification for their electrical work.

ESA specifically tells homeowners not to file the notification on behalf of somebody else doing the work.

Ask your contractor:

"Are you filing the ESA notification for this renovation?"

The answer should be clear.

18. Electrical Notification and Building Permit Are Not the Same Thing

This distinction is important.

An ESA electrical notification is not the same thing as a municipal building permit.

Depending on the scope of your kitchen renovation, other permits may also be required.

ESA explicitly notes that homeowners may need both an electrical notification and a building permit.

Your general contractor or municipality can help determine what additional approvals apply to the overall renovation.

19. Plan for Tomorrow's Kitchen, Not Just Today's

You're already opening walls and investing in a renovation.

Think about what you may want five or ten years from now.

Perhaps that's:

• Induction cooking

• Additional countertop appliances

• Beverage fridge

• Smart lighting

• More charging locations

• Additional kitchen technology

Planning ahead while the walls are open can be much easier than trying to retrofit everything later.

Kitchen Electrical Renovation Checklist

Before your electrician begins, try to have these decisions finalized:

• Final kitchen layout

• Refrigerator model/location

• Range or cooktop specifications

• Dishwasher location

• Microwave type/location

• Range hood

• Island design

• Small appliance locations

• Specialty appliances

• Pot light locations

• Pendant lighting

• Under-cabinet lighting

• Switch locations

• Smart controls

• Future appliance plans

The more information available before rough-in, the smoother the electrical portion of the renovation can be.

Frequently Asked Questions

Do I need an electrician for a kitchen renovation in Ontario?

If you're hiring someone to perform electrical work in Ontario, ESA says the work must be performed by a Licensed Electrical Contractor.

Does kitchen electrical work need an ESA permit?

ESA states that almost all electrical work requires a Notification of Work. Renovations that change original wiring generally fall under the residential renovation process.

Do kitchen outlets need GFCI protection in Ontario?

GFCI requirements depend on the receptacle location and installation. Ontario has specific GFCI requirements, and ESA provides additional guidance for kitchen counter receptacles and older split receptacle installations. Your Licensed Electrical Contractor should apply the current OESC requirements to your particular kitchen.

Do kitchen outlets need AFCI protection?

Ontario requires AFCI protection for many dwelling-unit receptacle branch circuits, but there are specific kitchen requirements and exceptions. ESA's kitchen bulletin identifies requirements for countertop, island, refrigerator, and other kitchen circuits.

Do I need 200-amp service for an induction stove?

Not automatically. An induction range can represent a significant electrical load, but whether your home requires a service upgrade depends on the existing service and total calculated electrical demand.

Should I call an electrician before ordering kitchen cabinets?

It's a good idea to involve your electrician once the kitchen design is substantially finalized and before construction reaches the electrical rough-in stage. Appliance locations, islands, countertops, lighting, and cabinetry can all affect the electrical layout.

Can my general contractor do the electrical work?

Not unless the business performing electrical work for hire is appropriately licensed. ESA states that only Licensed Electrical Contractors are legally licensed to perform electrical work for hire in Ontario.

Renovating Your Kitchen in Ottawa?

A successful kitchen renovation isn't just about beautiful cabinets and countertops.

What's behind the walls matters too.

Proper electrical planning can help ensure your new kitchen has the circuits, outlets, lighting, and electrical capacity needed for the appliances and technology you actually use.

If you're planning a kitchen renovation in Ottawa, Kevin Electric can help with the electrical portion of the project—from new circuits and receptacles to lighting, appliance connections, panel work, and other electrical upgrades.

The best time to involve your electrician is before the walls are closed and before the cabinetry is installed.

That way, the electrical system can be designed around the finished kitchen rather than trying to make the finished kitchen work around an outdated electrical system.
