A straightforward offer.

Weatherization, OESP and LEAP

Ontario Energy Affordability Services provides program guidance and application-route support. The official program administrator or designated intake agency determines eligibility, approved measures and payments. Senior status alone does not establish eligibility. Household, income, account, housing and program-specific requirements apply.

Weatherization information refers to Ontario Home Winterproofing and related Energy Affordability Program routes. OESP is a recurring electricity-bill credit. LEAP is emergency assistance for eligible utility arrears and possible disconnection, with payment directly to the utility. These programs are separate from Enbridge Sustain equipment agreements. Do not submit identification, tax records or account numbers through our general enquiry form; use the official secure intake process.

Free energy assessment

Our assessment is a no-cost review of your home, priorities and potential program pathways. It is not a certified EnerGuide evaluation, an equipment sizing calculation or a guarantee of a rebate. Programs that require a registered energy advisor have a separate evaluation process, timing and possible fees. We explain that step before you commit to work. Submitting a request does not book a confirmed appointment or enter an equipment agreement.

24/7, 365-day service

Service support is available throughout the year. The selected equipment agreement determines covered repairs, maintenance, charges and service arrangements. Availability does not mean every repair is free or guarantee an immediate arrival time. Use the service number on your agreement for urgent equipment assistance. The website enquiry form stores a request for follow-up and is not an emergency dispatch channel.

Qualification-based no-cost heating and cooling upgrades

No-cost upgrades are available through qualifying assistance programs, including Save on Energy’s Energy Affordability Program. Eligibility is based on household income or receipt of specified assistance benefits, utility-account requirements, existing heating equipment and a home assessment. The cold-climate heat-pump pathway is for qualifying electrically or oil-heated homes. A program delivery agent verifies the household and home, confirms suitable measures and arranges approved work. Not every home or requested upgrade qualifies.

No-cost assistance is separate from Enbridge Sustain lease-to-own, which requires monthly payments. Our team helps homeowners find and navigate these pathways; approval belongs to the program administrator. An installation fully funded by a no-cost program is not also counted as a homeowner-paid rebate expense.

Enbridge Sustain lease-to-own

Enbridge Sustain provides heating, cooling and hot-water solutions for homes, with lease-to-own and full-purchase options. It is an unregulated company distinct from Enbridge Gas Inc. Rebate and assistance programs have their own eligibility and application rules.

The standard lease-to-own term is typically 15 years. Standard installation is included without an upfront charge, and monthly payments cover annual maintenance, repairs and warranty protection. Sustain owns the equipment during the term; ownership transfers at the end, with early buyout available. Your signed agreement controls individual pricing, coverage and transfer conditions.

Our organization provides regional management and administration support for Enbridge Sustain in Ontario. Equipment agreements remain subject to Sustain’s terms. We help homeowners navigate rebates; government program administrators make their own eligibility and payment decisions. No upfront standard installation means monthly payments apply; it does not mean free equipment or that energy savings cover payments. Sustain describes a typical 180-month term and owns equipment during the agreement. The signed agreement controls pricing, taxes, service coverage, ownership transfer, early buyout and moving requirements. Request a written quote and buyout table. Agreement transfers require the provider’s written approval.

10% cashback promotion

Enbridge Sustain’s published offer applies to eligible residential lease-to-own agreements entered into September 14 to December 31, 2026, with installation after September 14. Cashback is 10% of the pre-tax equipment and installation value, with a maximum eligible value of $15,000 and maximum cashback of $1,500. Payment is by e-transfer after three successful monthly payments, with the account current and a zero balance. A 180-month agreement and regular monthly payments apply. Availability is limited to eligible residential customers in selected service areas. Builder and commercial agreements and cancelled or changed orders are excluded. This offer cannot be combined with other Sustain promotions. The provider may change or cancel the promotion.

Expired first-six-month discount

This is historical information, not a current offer. Sustain’s central lease page dated this promotion for eligible agreements entered into June 10 to September 30, 2026. It ended September 30, 2026. The first six monthly payments were reduced by 60%; regular payments applied afterward within a 180-month agreement. This offer cannot be combined with other Sustain promotions. Eligibility, service availability and the provider’s written agreement apply. This expired discount is not included in current-offers cards.

Rebate amounts and calculator

Amounts are potential maximums, not an eligibility decision or a promise of payment. Home Renovation Savings rules vary by heating fuel, equipment, size, location, ownership and application pathway. Enbridge-gas-heated homes purchasing eligible cold-climate air-source heat pumps can receive $500 per ton up to $2,000; eligible ground-source systems receive $3,000. Eligible electricity-, oil-, propane- or wood-heated homes purchasing systems can receive $1,250 per ton up to $7,500 for air-source, or $2,000 per ton up to $12,000 for ground-source. Eligible leased or rented heat pumps use the $500-per-ton air-source rate up to $2,000 or the $3,000 ground-source amount across eligible fuels. Capacity and model eligibility must meet the program’s definitions.

Insulation up to $7,700, solar and battery up to $10,000 and smart thermostats up to $125 refer to their separate current pathways and limits. These maximums should not be automatically added together. Do not claim the same measure twice. Assessment pathways require the correct pre-work assessment and qualifying upgrade combination; other pathways have their own pre-approval and installation sequence. The program administrator decides eligibility and payment. HER and HER+ are closed to new applications.

Home Renovation Savings rules and application steps

Energy savings estimates and the $1,900 scenario

The “up to $1,900 a year” figure is an illustrative scenario: $4,750 in annual energy spending multiplied by an assumed 40% reduction. It is not a measured result, typical-customer claim or prediction for your home. The eight-question home assessment provides a separate heating-cost estimate using your own bills and consumption. An energy assessment can help support your project-specific assumptions. Actual results depend on the home, upgrades, fuel prices, weather, occupancy and behavior, and may be lower, zero or negative.

Energy-bill savings exclude equipment lease or loan payments, maintenance costs and upgrade costs. A lower energy bill does not necessarily mean lower total household costs. Our payment comparison calculator uses the quote, tax and financing inputs you enter; it does not provide a financing offer, credit approval or present-value calculation.

How the home savings assessment works

The assessment uses eight steps: location, home details, heating equipment, comfort, upgrade priorities, energy bills, payment options and optional income-based support. Answers remain in your browser and are not included in contact links or analytics. This is a planning tool, not an energy audit, equipment-sizing calculation or program approval.

Heating-cost calculation

Baseline heating cost equals the annual cost entered multiplied by the space-heating share. Delivered heat equals annual fuel consumption multiplied by that share, the fuel energy factor and assumed existing efficiency. Energy factors are 10.55 kWh per cubic metre of natural gas, 10.6 kWh per litre of oil, 7.08 kWh per litre of propane and 1 kWh per kWh of electricity. These are approximate conversion inputs.

Existing resistance heating uses efficiency 1.0; existing heat pumps use seasonal COP 2.5. Combustion equipment under ten years uses efficiency 0.95, or 0.85 for oil; equipment ten to twenty years uses 0.80 and older equipment 0.65. Age is an imperfect proxy, so actual measured efficiency may differ. A new heat-pump scenario uses seasonal COP 2.0–3.0. Electricity cost equals heat supplied divided by COP, multiplied by the entered electricity rate. Gas homes use a hybrid scenario with half the annual heat supplied by the new heat pump and half by the existing system. Actual balance points and rates can materially change results.

The default 70% heating share and $0.16/kWh electricity rate are editable assumptions, not quoted current tariffs. Enter cost and consumption for the same twelve-month period. Use usage-related charges and variable delivery; exclude fixed charges. Equipment payments, cooling, hot water, maintenance, fixed charges and capital costs are outside the model. Negative savings are retained. Wood heating requires a tailored review and does not produce an automatic savings number.

Insulation and multiple upgrades

When insulation is selected, assumed heating-demand reductions are 10–20% for often-drafty homes, 5–15% for some drafts, 0–5% for comfortable homes and 3–12% when insulation is unknown. These are scenario assumptions, not measured Ontario averages. The reduction is applied before the heat-pump calculation to avoid counting the same savings twice. Floor area and home age shape next steps; they are not used to guess equipment capacity.

Rebates and assistance screening

The tool checks ownership, eligible house type, occupancy age, fuel and electricity connection before displaying heat-pump rebate pathways. Without program-rated capacity from an equipment quote, it shows the applicable maximum and rate. It does not add unrelated rebate maximums into a promised total. Existing heat pumps and unusual electricity connections require individual review. Heat-pump applications require program approval before installation.

Optional income screening uses the Energy Affordability Program comprehensive-support thresholds for one through seven-or-more people: $48,220, $68,193, $83,518, $96,439, $107,823, $118,113 and $127,576. Income is before tax for the previous year. Listed assistance benefits received in the past twelve months provide another potential pathway. A positive screening result is not an eligibility decision.
