Ask homeowners what they would change about their finished kitchen, and the answer is often not the cabinets or the countertop. It is the lighting: a dark prep area, a switch in an awkward spot, or an outlet that ended up exactly where the coffee maker should not be.
The fix is simple but time-sensitive. Under-cabinet lighting, outlets and switches work best when they are planned as part of your kitchen cabinet design, before cabinets are ordered and before walls are closed up. With shorter fall days arriving in Ontario, dark countertop areas are also easier to notice right now.
Quick answer: when should you plan under-cabinet lighting?
Plan it while your cabinet layout and electrical layout are still being finalized, and before wiring is covered by drywall. At that stage you can decide where the light connections go, where outlets are most useful, and how each light is switched, without reworking finished cabinets or walls.
Why Does Under-Cabinet Lighting Need Early Planning?
Under-cabinet lighting is task lighting. It puts light directly on the countertop where you chop, pour, read recipes and plug in appliances. Ceiling lights alone often leave that surface shaded, because your own body and the upper cabinets block light coming from above.
The challenge is that lighting touches several other decisions. Before cabinets and finishes go in, it helps to settle:
- Which countertop areas need task lighting
- Where the lights will connect to power
- Where outlets are needed
- Which lights will turn on together
- Where switches or dimmers will go
- How wiring and components will stay out of sight
These are far easier to coordinate on paper than around a finished installation.
How Do You Decide Where Under-Cabinet Lights Should Go?
Start with the countertop, not the light fixture. A common mistake is choosing a product first and then trying to make it fit.
Look at your kitchen plan and mark where you will:
- Prepare food
- Use a coffee maker or other small appliances
- Read recipes
- Pack lunches
- Clean and organize
Aim for even light across each work surface rather than bright spots next to dark patches. Exact positions depend on your cabinets, lighting system, backsplash and countertop, so confirm final placement with your cabinet designer and electrician.
How Do Upper Cabinets Affect Lighting and Wiring?
Your upper cabinets decide where lighting can be installed and how easily connections can be hidden. A clean finished look depends on planning this early.
During the cabinet design stage, review:
- The length of each wall cabinet run
- Where each run starts and ends
- Gaps around windows or appliances
- How a range hood or tall cabinet interrupts the run
- Where lighting connections can be discreetly placed
A well-designed cabinet layout can lose its polish if wires or components have to be added awkwardly after installation. If you want to see your layout before anything is built, CGD offers a virtual kitchen design service and an online kitchen visualizer to help you review the plan.
Where Should Outlets Go in a Kitchen Renovation?
Place outlets based on how you actually use the countertop, then confirm them against the electrical code. A coffee machine, toaster, kettle or blender can all change which locations are most useful.
Ask yourself:
- Where will the coffee station be?
- Which appliances stay on the counter, and which come out only when needed?
- Will any appliance sit inside or behind cabinetry?
- Will an outlet interrupt the backsplash or cabinet layout visually?
Do not choose outlet positions on looks alone. Accessibility, appliance needs and electrical safety all matter, and the Ontario Electrical Safety Code sets the rules for electrical installations. Your Licensed Electrical Contractor can confirm what applies in your kitchen.
How Should You Control Under-Cabinet Lights?
Decide on switching before the electrical plan is final. Picture an ordinary evening in the finished kitchen, and work backward from there.
Some households want ceiling lights, pendants and under-cabinet lights on separate controls. Others want different under-cabinet sections to work independently. No single setup suits every kitchen, so talk through questions like these:
- Should all under-cabinet lights turn on together?
- Would separate lighting zones be useful?
- Where should the main control be?
- Would dimming help your household?
- Do you prefer traditional controls or an optional smart-lighting setup?
Your daily routine is a better guide than a feature list. Add controls because you will use them, not because they are available.
How Does Light Look Against Your Cabinet and Countertop Colours?
Light reflects differently off different finishes. A white cabinet, a warm wood cabinet, a dark countertop and a glossy backsplash can each change how the same light looks.
If you can, compare cabinet, countertop and backsplash samples under lighting similar to what you plan to install. Check whether the combination feels too warm, too cool, too bright or uneven. The goal is a comfortable, practical workspace where your materials still look the way you expected.
Where Do Dark Spots Usually Show Up?
A kitchen can have plenty of ceiling light and still leave the counter darker than expected. When reviewing your plan, pay extra attention to:
- Long countertop runs
- Prep areas
- Corners
- Areas beside tall cabinets
- Spaces around appliances
- Coffee or beverage stations
Under-cabinet lighting brings light closer to the work surface, which helps with exactly these spots.
Who Does What: Cabinet Designer vs. Electrician
Your cabinet designer does not replace your electrician, and your electrician does not set your cabinet layout. The best results come from coordinating both plans.
Your cabinet plan can show cabinet dimensions, upper cabinet runs, appliance positions, countertop work areas, storage zones and where lighting needs to blend in visually. Your electrician then confirms the electrical requirements and completes the work.
In Ontario, the Electrical Safety Authority (ESA) says that if you hire someone to do electrical work in your home, that person must be a Licensed Electrical Contractor. If you hire a general contractor, confirm that a Licensed Electrical Contractor will do the electrical portion. You can check a contractor’s licence using ESA’s contractor locator tool.
Why the Licensed Electrical Contractor Step Matters
According to the ESA, almost all electrical work must be reported through a notification of work (often called a permit), filed before the work starts, and an electrical installation must be inspected before it is concealed. A Licensed Electrical Contractor files the notification and requests inspection for you, and the ESA can issue a Certificate of Acceptance once the work passes, which is useful for insurance and resale. The ESA also notes that a building permit is not the same as an electrical notification, so you may need both.
The ESA reports that unlicensed electrical work is four times more likely to have safety issues than work done by a Licensed Electrical Contractor. Process details can change, so confirm current requirements with the ESA or your contractor.
Under-Cabinet Lighting Planning Checklist
Before you approve your kitchen design, work through this list:
- Cabinet layout: Are upper cabinet dimensions final?
- Task areas: Which countertop zones need the most light?
- Light distribution: Does the plan avoid obvious dark and overly bright areas?
- Appliances: Do you know where countertop appliances will live?
- Outlets: Have outlet locations been reviewed against the layout?
- Switches: Do you know which lights should work together or separately?
- Dimming: Do you want adjustable lighting?
- Appearance: Have you checked how the light looks with your cabinet, backsplash and countertop colours?
- Wiring: Has the electrical plan been coordinated before wiring is covered and cabinets are installed?
- Electrical safety: Has a Licensed Electrical Contractor reviewed the electrical portion?
Make Lighting Part of Your Kitchen Cabinet Design
The easiest time to solve a lighting problem is before it exists. When you plan a renovation, treat under-cabinet lighting, outlets and switches as part of your overall kitchen cabinet design so your cabinet designer and electrician can coordinate before installation begins.
You do not need to understand wiring yourself. You only need to think about how you will use the kitchen and raise those questions early.

Frequently Asked Questions About Under-Cabinet Lighting
When should I plan under-cabinet lighting during a kitchen renovation?
Plan it while the cabinet and electrical layouts are still being finalized, and before wiring is covered by drywall. Early planning makes it easier to coordinate countertop work areas, upper cabinets, switches, outlets and electrical connections before finished surfaces limit access.
Where should under-cabinet lighting be placed?
Place it to give even, useful light across the countertop without obvious dark or overly bright areas. The best position depends on your cabinet dimensions, lighting system, backsplash, countertop and layout, so review placement as part of both the cabinet design and the electrical plan.
Should outlet locations be planned with the kitchen cabinets?
Yes. Appliance locations, countertop work zones, backsplash design and cabinetry all affect where outlets are useful. Have a Licensed Electrical Contractor confirm outlet locations and electrical requirements before installation.
Should under-cabinet lights have a separate switch?
They can. Many homeowners prefer to control under-cabinet, ceiling and pendant lights separately. Decide how you will use each lighting zone before the electrical work is finalized, so the switches and wiring match your routine.
Can I add smart controls to under-cabinet lighting?
Possibly, depending on the lighting and electrical system you choose. If smart controls matter to you, raise them during planning so power, controls and compatibility can be considered before installation.
Who can perform electrical work in an Ontario kitchen renovation?
In Ontario, if you hire someone to do electrical work in your home, the Electrical Safety Authority says they must be a Licensed Electrical Contractor. They can advise on Ontario Electrical Safety Code requirements, file the required notification of work and arrange inspection.
