Frequently Asked Questions

Who qualifies for the Hydro One Whole Home program?

Ontario homeowners who are Hydro One electricity customers and own their primary residence are eligible. Rental properties and landlords may have different requirements - check the Hydro One program page for details.

What upgrades are eligible for Whole Home rebates?

Eligible measures include air-source heat pumps, heat pump water heaters, smart thermostats, attic and wall insulation, air sealing, and window and door replacements. Each measure has its own rebate amount, and combining multiple upgrades in one application maximizes your total rebate.

Do I need a home energy assessment to apply?

An EnerGuide home energy assessment is recommended and may be required for certain upgrades. The assessment helps identify the most impactful improvements and supports your rebate application documentation.

Can Hydro One rebates be combined with other programs?

Yes. Hydro One rebates can often be stacked with the Ontario Home Renovation Savings program (homerenovationsavings.ca) for customers who are also Enbridge Gas customers. The Canada Greener Homes Loan and Enbridge HER+ are both closed to new applications. Confirm current stacking eligibility on the Hydro One website before you apply.

contractor.ca is not a government program and is not affiliated with Enbridge Gas, the IESO, or the Government of Canada. Rebate eligibility depends on your specific home, utility, and the program requirements at time of application. Always verify current amounts and eligibility directly at the official program website before starting work.
