What it is

The Energy Affordability Program (EAP) is IESO's income-qualified, fully-funded direct-install retrofit program for Ontario residential customers. It is the delivery channel through which the federal Oil to Heat Pump Affordability (OHPA) program reaches eligible Ontario homeowners.

For income-qualified oil-heated households, EAP plus federal OHPA stacks to up to $25,000 in funding ($15,000 federal + $10,000 provincial) plus a $250 upfront payment — a full no-cost retrofit experience delivered through pre-selected contractors.

Eligibility

EAP is income-tested. Ontario thresholds (2026) run from approximately $48,200 (1-person household after-tax income) to $127,500+ (7+ person household).

The household must be:

• An Ontario electricity-grid customer
• Owner-occupied or with landlord permission (rental program exists with different terms)
• Single-family, certain semi-detached and townhome property types

What it delivers — by heating fuel

For income-qualified propane customers, EAP offers insulation and weatherization but not a heat-pump conversion (because the propane-to-heat-pump path is not part of the OHPA-funded stream). The HRS heat-pump rebates (Regulation: Ontario Home Renovation Savings Program (HRS) — May 2026) remain available as a separate path.

Stacking and exclusivity

• EAP/OHPA delivery rolls HRS measures and federal OHPA into a single IESO-delivered no-cost retrofit. The customer does not file separate HRS paperwork.
• A home that has previously received an Enbridge or IESO Save on Energy rebate for the same measure is ineligible for the same measure under EAP.
• EAP and HRS are not stackable in the conventional sense for the same project — EAP absorbs HRS funding for income-qualified deliveries.

Application

• The homeowner applies directly through saveonenergy.ca's EAP intake.
• IESO routes the application to a pre-selected delivery contractor — the homeowner does not choose the installer.
• Third-party application is prohibited (homeowner must apply personally).

Future state

The Canada Greener Homes Affordability Program (CGHAP), a direct-install successor to the Canada Greener Homes Grant for low-to-median-income households, has not yet been signed in Ontario as of May 2026 (Manitoba is first). When it launches, it will likely flow through this same EAP channel.
