In short
- A pot light installed runs $150–$300 per light, materials and labour, on a Canada-wide HomeStars guide.
- ESA says swapping a surface fixture for a recessed light falls outside the like-for-like exemption, so the contractor files a notification.
- Under an attic, NRCan points to recessed fixtures with an insulation-contact, airtight (ICAT) rating.
- NRCan says the dimmer switch must be compatible with the type of bulb.

Three pot light jobs with three prices
- Open joists. A basement finish or a gutted kitchen, before drywall: the easy case on the Toronto guide. ESA wants the wiring inspected before insulation, vapour barrier or drywall hides it.
- Finished ceiling, attic above. Work from an accessible attic is the cheapest case on the same guide.
- Finished ceiling, another floor above. Wire runs inside a closed ceiling: the costliest case on the same guide, which says access holes may be needed.
Swapping old halogen cans for LED fixtures in the same holes is a fourth job. Open-joist work also appears on basement wiring.
Layout before the price
The count drives the total, so layout comes first. NRCan’s lighting guide treats recessed lights as one layer: aim some toward walls for general light, use aimable fixtures over a permanent feature, and keep a separate switch or dimmer for each layer. One Toronto firm puts lights over a counter 12–18 inches from the wall and centres one over the sink.
A sketch with the island, sink and sofa helps settle the count. For a chandelier or pendant, see light fixtures.
Under the attic: the Ottawa winter part
A top-floor ceiling is the edge of the heated house. NRCan lists pot lights among the spots where warm, moist air leaks into the attic, and that moisture shows up as frost on the cold side. Its guide adds that an attic above freezing warms the roof sheathing and melts the snow under it; the water refreezes at the overhang and starts an ice dam.
The fix it names is in the fixture: recessed lights with an insulation-contact, airtight (ICAT) rating, or approved covers. For standard housings NRCan says to keep insulation away from the fixture. NRCan also suggests LED flush or flat fixtures, which leave the cavity easier to seal. If the attic has vermiculite, Health Canada asks that it stay undisturbed; put that in the request.
Dimmers and colour
NRCan says the dimmer switch must be compatible with the type of bulb, and points to fixtures with dimming capability. Ask for the fixture and dimmer by model on the quote. NRCan’s pocket book suggests 2700–3000K for a warm room and about 3500K for a home office.
What moves the per-light price
- Access. An attic above or open joists costs least; a finished floor above costs most.
- Count. On the Toronto guide, one light can cost $250–$300 and 15 or more $150–$180 each.
- Wiring. A new circuit adds wire at $6–$8 a foot on the HomeStars guide.
- Ceiling repair. Drywall work runs $4–$6 a square foot; HomeStars lists junction box work at $10–$450.
- Fixture. The Toronto guide puts a basic LED unit at $20 and an adjustable one at $40–$60.
- Time. HomeStars gives $80–$130 an hour for mid-size cities such as Ottawa.
Hourly rates and call charges: what an electrician costs in Ottawa.
What the quote and the paperwork should show
A per-light line with the fixture model and its IC rating; the dimmers by model; new circuits; patching and paint; the ESA notification fee; HST. ESA lists an estimate with no ECRA/ESA licence number or ESA fee among signs of an unlicensed contractor, along with a cash discount. After the inspection, ESA issues a Certificate of Acceptance; ESA calls it important for insurance and resale. More on the steps: ESA permits.
Ontario requires a written agreement for home work over $50. The final bill can exceed an estimate in it by 10% at most unless you sign a change, and a contract signed at home has a 10-day cooling-off period.
Who takes your request
Ottawa Electric Desk passes your pot light request to one independent local electrical company. That company calls you back, sets the layout and price with you, and does the work.
Questions to ask the company
- Which housing or fixture model will you use, and does it carry an ICAT rating where it sits under the attic?
- Is the fixture in your per-light price, and is it dimmable on the dimmer you plan to fit?
- Will you file the ESA notification, and is the fee on the quote?
- Does the price cover patching and painting any extra openings cut to pull wire?
- What is your ECRA/ESA licence number, and will I get the Certificate of Acceptance?
Have this ready for the call
- Each room's size and ceiling height, with a sketch marking the counter, island, sink, art wall or reading chair
- What is above each ceiling: attic, another floor, or open joists in an unfinished basement
- A photo of the attic insulation taken from the hatch, without stepping in or moving it
- The number of lights you have in mind, and which ones share a switch or a dimmer
- Fixtures you already bought (brand and model), or a note that the company should supply them
- What comes out: a surface fixture, old halogen cans, or a bare ceiling
Questions people ask
Do pot lights need an ESA permit?
Yes. ESA’s Bulletin 2-3-18 says a recessed light in place of a surface fixture falls outside the like-for-like exemption, so the contractor files a notification. ESA’s homeowner page names pot light installations among the jobs that need one.
Can pot lights go in the top-floor ceiling under the attic?
NRCan says standard recessed lights are hard to air seal and can become a fire hazard if covered with insulation. It points to fixtures with an ICAT rating, or approved covers that can sit under insulation. Ask for the rating on the quote.
My LED pot lights flicker or buzz on the dimmer. Why?
NRCan notes that the dimmer switch must be compatible with the type of bulb. Name the dimmer and fixture brands in your request. For flicker across the house, see flickering lights.
How many pot lights does a room need?
One Toronto firm’s guide uses spacing equal to half the ceiling height, so about 4 feet apart on an 8-foot ceiling, with the outer row half that distance from the wall. NRCan’s lighting guide warns against using pot lights as the only light in a room, since they can leave shadows.
Can I buy the fixtures myself?
HomeStars notes that supplying your own fixtures removes the markup on materials. Give the model in the request so the company can check the IC rating and the dimmer match.
The attic has vermiculite insulation. Can pot lights still go in?
Health Canada says vermiculite may contain asbestos: leave it undisturbed and hire professionals trained to handle asbestos before a renovation that would disturb it. Mention it in the request.
