⭐ Best value — most homeowners save more
Income-qualified + Enbridge Gas customer? Check the FREE path first. Enbridge's Home Winterproofing Program installs wall, attic or basement insulation, draft proofing and a smart thermostat at no cost for income-eligible households (renters qualify with landlord permission — income limits from $48,220 for one person to $127,576 for 7+). Worth confirming before paying for the assessment path: enbridgegas.com — Home Winterproofing (verified Aug 16, 2026).
Insulation Areas Covered
The program covers insulation for all areas of your home: attic, exterior walls, basement walls, crawlspace, exposed floors, and cathedral ceilings. Your energy advisor will recommend which areas need the most improvement based on your pre-retrofit assessment.
Pro tip: Adding air sealing ($250 rebate) to your insulation project unlocks the bundled path AND makes your insulation 30-40% more effective. Most contractors recommend doing both together.
Eligibility
Own a detached, semi-detached, townhouse, row house, or mobile home in Ontario. Must be an Enbridge Gas customer or connected to the Ontario electricity grid. Home must be occupied for 6+ months. Condos and apartments are not eligible.
Bundled path warning: Do NOT start any work before the pre-retrofit energy assessment. Post-assessment must be completed within 180 days. Keep all invoices.
