How much does energy audit home cost in Toronto?

A home energy audit in Toronto typically costs between $150 and $600, depending on the size of your home, the type of audit, and whether you're accessing government-subsidized programs.

The most important thing to know is that you may be able to get your audit done for free or at a heavily reduced cost through federal and provincial programs. The Canada Greener Homes Grant program has offered subsidized audits through registered energy advisors, and the Ontario Home Efficiency Rebate Plus (HER+) program, delivered through Enbridge Gas, covers the cost of pre- and post-retrofit audits entirely when you're planning eligible upgrades. This is the route most Toronto homeowners should explore first before paying out of pocket.

Types of audits and what they cost:

A basic walk-through audit (sometimes called a desktop or visual audit) runs $150–$250. This is a surface-level assessment — useful for identifying obvious issues but limited in depth.

A full home energy audit by a Natural Resources Canada (NRCan) registered energy advisor runs $300–$600 for a typical Toronto home (detached, semi, or townhouse). This includes a blower door test, thermal imaging, and a detailed report with an EnerGuide rating. This is the type required to qualify for government rebate programs, so it's the one most homeowners should get.

Condo and smaller unit audits tend to fall at the lower end of the range, though condo-specific audits are less common since building envelope improvements are typically managed by the condo corporation.

Toronto-specific context: Older homes in neighbourhoods like The Annex, Leslieville, or Cabbagetown often have significant air leakage, outdated insulation, and drafty windows — meaning the audit frequently pays for itself many times over by identifying upgrades that qualify for rebates worth $5,000–$10,000+. Post-war bungalows in Scarborough, Etobicoke, and North York are also prime candidates, as many have never had a formal energy assessment.

Is it worth it? Almost always yes. The audit report tells you exactly where your home is losing heat (critical in Toronto winters), prioritizes upgrades by cost-effectiveness, and — crucially — is the required first step to access government rebate programs. Without a pre-retrofit audit by a registered advisor, you cannot claim most major rebates.

Your next steps: Start by checking eligibility for the Enbridge Gas HER+ program at enbridgegas.com or calling Enbridge directly, as a subsidized or free audit is almost always the better starting point. If you don't qualify for subsidized programs, look for NRCan-registered energy advisors — you can find them through the Natural Resources Canada website or browse our directory at the Toronto Construction Network for local professionals who can connect you with certified advisors in the GTA.
