Lighting Level Testing & Assessment in Toronto
City Brite Electric Inc takes professional lighting-level measurements for commercial and industrial properties across Toronto, with particular service coverage in North York. Using light-metering equipment, we record how much light actually reaches floors, work surfaces, aisles and common areas, identify where it is uneven, inadequate or excessive, and give you documented findings you can act on.

What Lighting Level Testing Is
Lighting level testing is the measurement of illuminance — the amount of light falling on a surface — at defined points in a space. Instead of judging a room by eye, which adapts quickly and is easily fooled, a light meter gives a number that can be recorded, compared between areas and compared again later.
A lighting-level assessment goes a step further. The readings are taken where the work actually happens, at the height it happens, and are looked at against what the space is used for. The result is a record of where the lighting is doing its job and where it is not.
Lux and Foot-Candles
Illuminance is recorded in one of two units, and a good report makes clear which one it is using.
Lux (lx)
The metric unit: one lumen of light spread over one square metre. Lux is the unit used in most Canadian and international guidance.
Foot-candles (fc)
The imperial unit: one lumen over one square foot. Still common on older drawings, fixture data sheets and US-based documents.
Converting between them
One foot-candle is roughly 10.76 lux. Readings can be recorded in lux, foot-candles or both, so they line up with whatever documents you are comparing them against.
Why Proper Illumination Matters
Dim aisles, shadows across work surfaces and glare at a workstation can make movement and detailed tasks more difficult. Documented measurements help a building owner investigate concerns rather than relying only on how bright a room appears.
More light is not always the answer. Excess illumination can use unnecessary energy, while fixture position and bright reflections can contribute to glare. Illuminance readings help assess light levels; glare and visual comfort also need consideration and cannot be determined from a lux reading alone.
- Visibility for safe movement through aisles, stairs, corridors and garages
- Enough light on the task for accurate work at benches, desks and counters
- Consistency between areas, so eyes are not constantly readjusting
- A factual basis for tenant, employee or inspection-related lighting concerns
- Before-and-after evidence when lighting is changed or upgraded
How Lighting Needs Vary by Space and Task
There is no single correct lighting level for a building. What is appropriate depends on the activity, the detail of the task, who is doing it and how long they spend there. These are the spaces we are asked to measure.
Offices
Readings at desk height across open-plan areas, private offices and meeting rooms, looking at task lighting, uniformity and areas affected by screens and glare.
Warehouses
Aisle-by-aisle measurements between racking, at pick faces, loading docks and staging areas, where high-bay fixtures and tall shelving create shadowed zones.
Manufacturing and work areas
Measurements at machines, benches and inspection points, where the detail of the work varies from one station to the next.
Retail spaces
Sales floors, cash areas, stockrooms and back-of-house, where display lighting and general lighting can differ sharply.
Commercial buildings
Lobbies, tenant suites, washrooms and shared amenities in multi-tenant office and commercial properties.
Parking garages
Drive aisles, parking stalls, ramps, pedestrian routes and exits, where fixtures are often widely spaced and ageing unevenly.
Corridors and common areas
Hallways, stairwells, entrances and elevator lobbies — the circulation spaces people pass through without noticing the lighting until it fails.
Electrical and service rooms
Where applicable, lighting in electrical rooms, mechanical rooms and service spaces where equipment has to be read and worked on.
Workstations and task areas
Spot readings at the specific surface where the task is done, rather than an average across the room.
Existing Systems, Retrofits and Before-and-After Measurements
Existing lighting systems
An assessment of what you have now: where output has dropped, where fixtures are failed or missing, and where the original layout no longer suits how the space is used after a tenant improvement or change of use.
Lighting retrofit assessments
Before an LED retrofit, measurements show which areas are under-lit, over-lit or about right, so the retrofit can be planned around real conditions instead of a one-for-one fixture swap.
Before-and-after measurements
Readings taken at the same points before and after lighting work give a documented comparison of what changed — useful for property managers reporting to owners, and for confirming a retrofit did what it was meant to.

Ontario Lighting Requirements: What Applies Depends on the Workplace
People often ask what the legal lux level is for an office or a warehouse in Ontario. There is no single figure that applies to every workplace. Ontario workplace health and safety regulations contain lighting provisions for certain types of workplaces, and other requirements, building-related rules or recognized guidance may be relevant depending on the location, the activity and the kind of property.
Organizations such as the Illuminating Engineering Society (IES) and standards bodies publish recommended lighting levels for different tasks and spaces. These are guidance, and which document is appropriate depends on what the space is used for.
What we do is take documented lighting measurements and, where appropriate, compare measured lighting levels with applicable requirements or recognized guidance that you or your advisers identify. We do not certify a workplace as compliant, and a lighting-level assessment is not automatically a formal compliance determination, engineering review or photometric design. If you need one of those, we will say so, so that you can involve the right professional.
How a Lighting-Level Assessment Works
A typical assessment follows these steps. The scope is agreed with you first, so the measurements answer the question you actually have.
Discuss the areas and lighting concerns
We talk through which spaces you want assessed and why — complaints, a planned retrofit, a tenant change, an inspection question or routine preventative maintenance.
Identify the relevant work areas and tasks
We establish what happens in each area and where, so readings are taken at meaningful points and heights rather than at random.
Take lighting measurements at appropriate locations
Using professional light-metering equipment, we take readings at work surfaces, floors, aisles and other locations suited to the space.
Record readings in lux and/or foot-candles
Each reading is recorded against its location, in the unit or units that suit the documents you are working with.
Identify dark areas, inconsistencies and other concerns
We note under-lit and over-lit areas, uneven coverage, failed or deteriorated fixtures and other lighting concerns observed on site.
Provide documented findings
You receive documented findings appropriate to the scope of the assessment that was agreed.
Recommendations or a quotation for upgrades
Where improvements are desired, City Brite Electric can provide electrical recommendations or a separate quotation for lighting upgrades.

For Property Managers, Facility Managers and Building Owners
An assessment can support property managers investigating tenant concerns, facility managers planning preventative maintenance, building owners budgeting for a lighting retrofit, employers responding to workplace lighting concerns, and general contractors checking conditions around a tenant improvement.
Because we are an electrical contractor rather than a testing-only company, the same people who measure the lighting understand the circuits, fixtures and controls behind it. When a reading points to a problem, we can explain the likely electrical options in practical terms — and, if you want the work done, quote it separately.

Frequently Asked Questions
What is lighting level testing?
It is the measurement of how much light falls on surfaces in a space, taken with a light meter at defined locations. The readings are recorded in lux or foot-candles so lighting can be compared between areas and over time.
What is the difference between lux and foot-candles?
Both measure illuminance. Lux is lumens per square metre; foot-candles are lumens per square foot. One foot-candle is roughly 10.76 lux. We can record readings in either unit, or both.
How are lighting levels measured in a warehouse?
Readings are taken along aisles between racking, at pick faces, loading docks, staging areas and other work locations, at heights that suit the tasks. Tall racking and high-bay fixtures often create shadowed zones that only show up when aisles are measured individually.
Can you measure lighting levels in an office?
Yes. Office assessments typically include readings at desk and work-surface height across open areas, private offices, meeting rooms, corridors and common spaces.
Does Ontario require specific lighting levels in workplaces?
There is no single lux level that applies to every workplace. Ontario workplace regulations contain lighting provisions for certain workplaces, and other requirements or recognized guidance may apply depending on the location, the activity and the type of property. We take documented measurements and can compare them with applicable requirements or recognized guidance where appropriate, but we do not certify a workplace as compliant.
When should a business have its lighting levels assessed?
Common triggers are complaints about dim or uneven lighting, a planned LED retrofit, a change of use or tenant improvement, racking or layout changes, a workplace lighting concern raised by staff, or as part of preventative maintenance.
Can you test lighting before and after an LED retrofit?
Yes. Measuring at the same points before and after the work gives a documented comparison of what changed, and helps confirm the new lighting suits each area.
Pot lights, LED fixtures and lighting upgradesCan City Brite Electric improve areas with inadequate lighting?
Where improvements are desired, we can provide electrical recommendations or a separate quotation for lighting upgrades — for example replacing failed or outdated fixtures, adding fixtures or changing controls.
Do you provide lighting level testing in North York?
Yes. We provide lighting-level testing in North York and throughout Toronto and the wider GTA.
What types of commercial properties can be tested?
Offices, warehouses, manufacturing and work areas, retail spaces, multi-tenant commercial buildings, parking garages, corridors and common areas, and electrical or service rooms where applicable.
