Do I need a home energy assessment to get rebates in Ontario?

Answered by the Canadian Energy Standard team · Updated September 13, 2026 · 4 min read

Quick answer

Not for everything. Heat pumps, attic insulation on its own, smart thermostats, appliances and solar with battery storage don't need an assessment. Insulation across the home, windows and doors, heat pump water heaters and air sealing start with one.12
