Oakville has some of the best mature trees and the most varied houses in the GTA, from heritage homes south of Lakeshore to new stone fronts in the Preserve. Good lighting makes the most of both. Here is what it costs, how we design it street by street, and the questions that tell you whether a quote is any good.
What landscape lighting costs in Oakville
| System | Fixtures | Typical scope | Installed, 2026 |
|---|---|---|---|
| Starter | 6 to 8 | Front path and two uplights on the house or a tree | $2,400 - $4,800 |
| Standard | 12 to 18 | Front facade, path, a few trees | $4,800 - $9,800 |
| Full property | 25 to 40 | Front and back, trees, patio, steps | $9,800 - $26,000 |
| Per fixture, average | 1 | Fixture, lamp, cable, connector and labour | $270 - $560 |
| New exterior GFCI outlet for the transformer | n/a | Licensed electrician, if you do not have a suitable outlet | $350 - $900 |
| Yearly maintenance visit | n/a | Re-aim, clean, test, replace failed lamps | $150 - $400 plus parts |
Most Oakville front yards land in the standard band, because a two-storey facade with mature trees needs more fixtures than a bungalow. Our landscape lighting cost guide breaks the price down by component.
Lighting design by Oakville neighbourhood
- Old Oakville and the heritage core: brick and clapboard facades, deep porches and old trees. Warm 2700K grazing light on the brick, subtle path lights, and fixtures hidden in the planting so the house reads as it did a century ago.
- Bronte and the lakefront streets: wind and lake spray. We use solid brass fixtures and sealed connections, because aluminum and plastic corrode fastest near the water.
- Glen Abbey: 1970s and 1980s homes with mature canopy. Moonlighting from high in the trees and uplighting on specimen trees give these lots depth without lighting every surface.
- Joshua Creek, River Oaks and Iroquois Ridge North: stone and stucco fronts and newer planting. Wash lights on the facade, path lights along the walk, and a plan that leaves room to add fixtures as the trees grow.
- North Oakville, the Preserve, Palermo and Westmount: new builds with tall facades and young trees. Facade and column lighting does most of the work at first.
What separates a good system from a bad one
- Fixture material. Cast brass or copper lasts decades. Aluminum corrodes eventually near salt and the lake. Plastic lasts 3 to 6 Ontario winters.
- Voltage at every fixture. Low-voltage systems lose voltage along the cable. A multi-tap transformer and properly planned cable runs keep every lamp in its working range. Kichler, for example, recommends more than 10 volts at the end of the run.
- One colour temperature. 2700K suits brick and wood, 3000K suits grey stone and foliage. Never mix them in one view, and stay at 3000K or below.
- Glare control. You should see the light, not the bulb. Shrouded fixtures, careful aiming and no floodlights pointed at the street or the neighbours.
- Replaceable lamps. Fixtures with a replaceable LED lamp are much cheaper to keep running at year ten than sealed units.
ESA notification: the step most quotes skip
In Ontario, a low-voltage lighting system is still an electrical installation. ESA Bulletin 2-3-18 requires a notification for new installations and leaves lighting out of its low-voltage exemption, and ESA has told Landscape Ontario that landscape lighting needs a permit even when the transformer plugs into an existing outlet. The transformer has to plug into a GFCI-protected outlet, and adding a new outdoor outlet is 120V work for a Licensed Electrical Contractor. We look after the notification. A quote that never mentions ESA is a quote that is cutting a corner.
How we install landscape lighting in Oakville
- Night walk and plan. We look at the property after dark, mark what deserves light, and draw a fixture and cable plan.
- Locates. Before any cable is trenched, we request a free locate from Ontario Dig Authority (formerly Ontario One Call). Locates do not cover private lines, such as power to a shed or an old lighting circuit, so tell us about anything buried on your property.
- Transformer and outlet. A stainless multi-tap transformer with a photocell and timer or smart control, plugged into a GFCI outlet. If you need a new outlet, a licensed electrician installs it.
- Cable and fixtures. Direct-burial cable run in planned home runs, fixtures connected with sealed, gel-filled connectors.
- Aiming at dusk. We come back after dark to aim every fixture and set the timer.
Maintenance and repairs
A good LED system needs one visit a year, usually in spring: re-aim fixtures that frost or mowers have nudged, lift fixtures buried by mulch, trim plants that have grown over them, clean lenses, test voltage and reset the timer. Expect $150 to $400 plus parts. We also repair and upgrade older systems, trace dead zones, and convert halogen lamps to LED for about $18 to $45 a lamp.
Frequently asked questions
How much does landscape lighting cost in Oakville?
About $270 to $560 per fixture installed in 2026, so $2,400 to $4,800 for 6 to 8 fixtures, $4,800 to $9,800 for 12 to 18, and $9,800 to $26,000 for a full property.
Do I need a permit for landscape lighting in Oakville?
An ESA notification, yes. ESA requires notification for new electrical installations, and its low-voltage exemption does not cover lighting. A new outdoor outlet for the transformer must be installed by a licensed electrician.
What colour temperature is best?
2700K for brick, wood and warm-toned houses, 3000K for grey stone and foliage. Keep every fixture in one view the same and stay at 3000K or below.
Which fixtures last near the lake?
Solid brass or copper. Lake spray and road salt corrode aluminum and crack plastic far sooner.
How much does it cost to run?
About $25 to $40 a year in hydro for a 16-fixture LED system running six hours a night.
Can you fix or upgrade an existing system?
Yes. We trace dead zones, replace failed fixtures and convert halogen systems to LED for about $18 to $45 a lamp.
