LED Lighting Rebates in Ontario: A 2026 Guide for Businesses
Save on Energy moved most lighting incentives to Instant Discounts on June 30, 2026. What Ontario businesses can claim, who qualifies and how to apply.

Ontario businesses can still claim rebates on LED lighting upgrades in 2026, but the programs were restructured this summer and most lighting no longer sits where contractors and buyers expect to find it.
On June 30, 2026, the Independent Electricity System Operator moved most lighting measures out of the Save on Energy Retrofit Program and into the Save on Energy Instant Discounts Program. If your last lighting project ran through a Retrofit application, the process for your next one is different. This guide covers what each program funds as of August 21, 2026, who qualifies, what gets claims rejected, and the rules that decide how much money actually reaches your invoice.
Program rules and incentive rates change. Every figure below is dated, and the current numbers always sit with the Save on Energy business and industry programs.

What changed for Ontario LED lighting rebates on June 30, 2026
Save on Energy is the incentive brand delivered by the IESO, Ontario's electricity system operator. Two of its programs fund commercial and industrial LED work, and the split between them moved this year.
In its own wording, Save on Energy states that "most lighting measures previously available as part of the Retrofit program are now offered through the Save on Energy Instant Discounts Program" (Retrofit program measures and incentives, effective June 30, 2026).
Two practical consequences for facility teams:
Standard fixture upgrades are now a point-of-sale discount, not an application. LED tubes, troffers, high bays, low bays, downlights and standard controls come off the invoice at purchase. There is no form to submit and no cheque to wait for.
A short list of lighting measures stayed in Retrofit. Networked lighting controls, refrigerated display case fixtures and horticultural grow lighting are still claimed through a Retrofit application, and several of those rates were reduced on the same date.
Retrofit applications that were complete and submitted before June 30, 2026 are honoured at the rates in effect when they were submitted.
The Save on Energy Instant Discounts Program
This is where most commercial LED retrofits are funded as of August 2026.
The discount is applied by a participating distributor at the point of sale. You buy eligible fixtures, the discount comes off the price, and Save on Energy confirms there is "no paperwork required."

Who is eligible
The program requirements (Instant Discounts Program Requirements, Version #03, April 20, 2026) define an eligible end-use customer as the owner, operator or employee of:
Commercial spaces such as offices, retail and grocery stores, restaurants, hotels and warehouses
Industrial buildings in sectors including food and beverage, automotive, plastics, steel, mining, paper and chemicals
Institutional buildings including hospitals, schools, universities, government and municipal facilities
Multi-family buildings, for common areas only and not in-suite residential areas
Agricultural facilities including dairy, swine and poultry farms, greenhouses and nurseries
Products must be installed in Ontario, in a single facility, behind the meter of an electricity consumer connected to the IESO-controlled grid or a distribution system.
What products qualify
Eligible measures are "general-purpose and specialty Energy Star or Design Lights Consortium (DLC) qualified lighting products." Listing is not optional. The program requirements state that products must be "Listed under the Energy Star or Design Lights Consortium," and distributors must produce the corresponding listing on request.
The covered range includes LED tubes in T5, T5HO and T8 formats, linear ambient fixtures, troffers, high bay and low bay fixtures, recessed downlights, reflector lamps, refrigerated display case fixtures, and lighting controls such as occupancy sensors and integrated controls. Networked lighting controls are the exception and remain under Retrofit.
Per-unit discounts run from $2 on a basic LED tube replacement to $80 on the highest-output LED high bay fixtures, with lighting controls up to $30 per unit, as listed on the Save on Energy Instant Discounts Program page in August 2026.
How much of the incentive has to reach you
This is the part of the program almost nobody publishes, and it is the single most useful thing a buyer can know.
The incentive is paid to the distributor, not to you. The program requirements then oblige that distributor to pass a defined share of it through: "each Participating Distributor must pass on a minimum of 60% of the corresponding incentive amount."
They must also make it visible. The pass-through has to appear "as a line item on the purchaser sales invoice," and that line item must read "Save on Energy Instant Discounts." Where a contractor buys on your behalf, the distributor is required to ask that contractor to show the incentive received and document it on the invoice to you under the same wording.
Check your invoice for that line. If it is not there, ask why before you pay.
The 90-day rule
Eligible products must be installed at the end-use customer's facility within 90 days of the purchase date. Equipment that sits in a storage room past that window falls outside the program requirements.
The Save on Energy Retrofit Program
The Retrofit Program is still the right route for larger and more complex electrical projects, and for the lighting measures that did not move.

It runs two streams, and both are "capped at 50 percent of eligible project costs":
Prescriptive. Set incentive amounts for common upgrades drawn from a defined measures list.
Custom. For complex or unique retrofits, with the incentive calculated from verified kWh or kW peak reductions.
Lighting measures still funded through Retrofit
As published after the June 30, 2026 update:
Measure | Incentive |
|---|---|
Networked lighting controls | $0.30/kWh (reduced from $0.35/kWh) |
Refrigerated display case LED fixture | Up to $25 |
Greenhouse advanced lighting control | $0.30/kWh (reduced from $0.35/kWh) |
Horticultural LED grow top light | Up to $180 per fixture (reduced from $200) |
Horticultural inter-lighting LED grow light fixture | $100 |
Vertical farming LED grow lights | Up to $100 per fixture |
Apply before you commit
The rule that costs Ontario businesses the most rebate money is a timing rule, and it is easy to trip.
Retrofit participants "must not have entered into a binding commitment prior to applying to the Retrofit program." A binding commitment includes a purchase order, a signed contract or the purchase of equipment. Sign the contract first and the incentive can be reduced or refused.
Save on Energy allows work to start after submission but warns that "if you choose to start your project before your application is pre-approved, it is important to know there is a risk that your project may receive a lower than expected incentive amount, or that your project application may not be approved."
Plan the application into the project schedule, not after it.
Regional adders
Facilities in areas with local electricity system constraints can qualify for a bonus. Eligible participants "can receive double the standard incentives offered for Custom and certain Prescriptive measures," still capped at 50 percent of eligible project costs. Eligibility is set by location, so it is worth confirming before you assume the base rate.
Retrofit questions go to the IESO support line at 1-844-303-5542 or [email protected].
Not sure which stream your project falls under? It depends on your fixture count, mounting heights and operating hours, and the answer changes what you can claim. Think Green Solutions establishes that baseline and sequences the application before any binding commitment. Get in touch to start.
The Small Business Program
Businesses with 50 or fewer employees have a separate and more generous route.
The Small Business Program provides a free on-site assessment and direct installation, with incentives of up to $3,000 for lighting and up to $2,500 for refrigeration and smart thermostats, a combined maximum of $5,500. Save on Energy states there is "no cost to receive an assessment, or to have eligible lighting upgrades of up to $3,000 and non-lighting upgrades of up to $2,500 installed."
You need to own the space or have the building owner's consent. Applications go through 1-833-825-7283 or [email protected]. Current eligibility and amounts are published on the Save on Energy Small Business Program page.
Local initiatives
Save on Energy also runs targeted programs where the local grid is constrained. The BizEnergySaver Program covers commercial, industrial, institutional and multi-unit residential buildings in Ottawa and in the Richview South area of Toronto, offering a free assessment plus direct installation of LED upgrades, adaptive lighting controls for stairwells and parking garages, high and low bay upgrades, and variable frequency drives. Eligibility is decided by the first three digits of the building's postal code.
These initiatives open and close by area. If your facility is outside the current zones, the Instant Discounts and Retrofit routes above are the ones that apply.
Which program applies to your project
Instant Discounts | Retrofit | Small Business | |
|---|---|---|---|
Best for | Standard fixture and lamp replacement | Networked controls, horticultural, complex electrical | Businesses with 50 or fewer employees |
How you get it | Discount at point of sale | Application with pre-approval | Free assessment and direct install |
Paperwork | None for the customer | Full application | Handled by the program |
Cap | Per-unit amounts by measure | 50% of eligible project costs | $3,000 lighting, $5,500 combined |
Timing risk | Install within 90 days of purchase | Apply before any binding commitment | Assessment first |
Six reasons lighting rebate claims get reduced or rejected
Every one of these comes straight from the published program rules, and all six are avoidable.
You signed before you applied. Retrofit treats a purchase order, signed contract or equipment purchase as a binding commitment that predates the application.
The product is not listed. Instant Discounts measures must carry an ENERGY STAR or DLC listing. A comparable fixture that is not listed does not qualify, whatever its specification sheet says.
It is new construction. Instant Discounts excludes new facilities, new additions, major renovations that convert the building to another use, and major renovations that leave the facility unfit for occupation for 30 days or more while at least two building systems are replaced. The Ontario Building Code already requires efficient lighting in new builds, so the incentive is aimed at retrofits of existing buildings.
Installation missed the 90-day window. The clock starts at the purchase date, not at project handover.
The distributor is not participating. Instant Discounts is delivered through participating distributors only. Buying the same fixture elsewhere forfeits the discount.
The measure was already funded. An eligible customer "must not have received any other financial incentives for the applicable Eligible Measures purchased under this Program from any other program or initiative funded by the IESO or the Government of Ontario." The restriction is written against the specific measures purchased, so confirm the split with the program administrator before planning a project around two funding sources.
What incentives do to a lighting project's payback
An incentive shortens payback. It does not create it. The savings that repay a retrofit come from the wattage reduction, the operating hours and the maintenance you stop paying for, and the incentive pulls the recovery date forward from there.
That is why the number that matters is not the rebate. It is the measured baseline. A lighting energy audit establishes the existing fixture count, wattage, mounting heights, operating hours and lighting levels, which is also the documentation a Retrofit application needs.

Over three retrofit phases since 2012, Canadian Tire Georgetown reports more than $670,000 in savings and more than a decade of operation with almost no lighting maintenance. The full project is documented in the Canadian Tire Georgetown case study.
How Think Green Solutions handles the incentive work
Think Green Solutions is a Cambridge, Ontario based provider of turnkey LED lighting and controls projects for commercial, industrial and institutional facilities. Incentive administration is part of the project, not a document we hand you at the end.

That work covers:
Program identification and eligibility review for your facility and measures
Savings calculations and engineering documentation
Application preparation and submission
Pre-approval coordination, sequenced so the application lands before any binding commitment
Post-installation measurement and verification
Final rebate collection and reporting
Installation is carried out by licensed electricians we manage end to end, so the scheduling, the documentation and the program deadlines stay on one plan.
Fixtures are backed by a 10 year limited warranty on LED panels, high bays and low bays, a 5 year limited warranty on tubes, strips, wall packs and exterior fixtures, and a 5 year colour stability and lumen output guarantee on every fixture.
More detail sits on our incentives and rebates page.
Frequently asked questions
Are there LED lighting rebates in Ontario?
Yes. As of August 2026, Ontario businesses claim LED lighting incentives mainly through the Save on Energy Instant Discounts Program, applied by participating distributors at the point of sale. Networked lighting controls, refrigerated display case fixtures and horticultural grow lighting are claimed through the Save on Energy Retrofit Program instead. Businesses with 50 or fewer employees can use the Small Business Program.
What is the Save on Energy Retrofit Program?
It is the IESO incentive program for energy-efficiency retrofits in commercial, industrial, institutional, agricultural and multi-residential facilities. It runs a Prescriptive stream with set amounts for listed measures and a Custom stream calculated from verified kWh or kW reductions, both capped at 50 percent of eligible project costs. Most lighting measures moved out of it on June 30, 2026.
How do Instant Discounts work?
You buy eligible ENERGY STAR or DLC listed lighting from a participating distributor and give your business name and installation address at checkout. The discount is applied to the price at that moment. The distributor must pass through at least 60 percent of the incentive and show it on the invoice as a line item reading "Save on Energy Instant Discounts."
How much can an Ontario business get back on LED lighting?
It depends on the fixture. Instant Discounts run from $2 per unit on basic LED tube replacements to $80 per unit on the highest-output LED high bays, with controls up to $30 per unit. Retrofit incentives are capped at 50 percent of eligible project costs. The Small Business Program covers up to $3,000 of lighting. Those amounts were current in August 2026.
Do I need to apply before buying equipment?
For the Retrofit Program, yes. Participants must not have entered into a binding commitment, meaning a purchase order, signed contract or equipment purchase, before applying. For Instant Discounts there is no application at all, but the equipment has to be installed within 90 days of purchase.
Do LED high bay fixtures qualify?
Yes, provided they carry an ENERGY STAR or DLC listing and are bought from a participating distributor for an existing building. High bays sit at the top of the Instant Discounts range at up to $80 per unit as of August 2026.
Do lighting controls and occupancy sensors qualify?
Standard lighting controls, including occupancy sensors and integrated controls, moved into Instant Discounts on January 1, 2025. Networked lighting controls stayed in the Retrofit Program and are incentivized at $0.30/kWh following the June 30, 2026 update.
Can new buildings claim lighting incentives?
No. Instant Discounts covers retrofits of existing buildings where less efficient lighting was already in place. New construction, new additions and major renovations that convert the building's use are excluded, because building code already requires efficient lighting in new builds.
Where do I confirm the current rates?
Program rules and rates change, sometimes twice a year. Confirm current figures on the Save on Energy programs and incentives page or through the IESO Retrofit support line at 1-844-303-5542. You can also contact Think Green Solutions and we will check them for you. Tracking these changes and preparing, submitting and following the incentive applications through to payment is part of every project we deliver, so you do not have to work the rate tables yourself.
Start with the baseline, not the rebate
The businesses that capture the most incentive money are not the ones chasing the highest per-fixture number. They are the ones who measured the facility first, specified listed products, and got the application in before anyone signed anything.
If you are planning a lighting upgrade in Ontario, book a lighting energy audit and we will identify the programs your facility qualifies for as part of it. Get in touch to start.
