Do I need a pre-retrofit EnerGuide audit for the rebate?

Yes, you need a pre-retrofit EnerGuide evaluation to qualify for Canada Greener Homes Grant rebates. This initial assessment establishes your home's baseline energy performance and identifies eligible upgrades.

The pre-retrofit evaluation must be completed by a certified Natural Resources Canada energy advisor before you begin any work. During this visit, the advisor will conduct a blower door test, inspect your current windows and doors, and provide you with a detailed report showing your home's current energy rating and recommended improvements. This evaluation costs around $300-500 in the Ottawa area, but you'll receive a $600 rebate that covers this cost plus provides additional funding.

After completing your window or door upgrades, you'll need a post-retrofit evaluation to confirm the improvements and calculate your final rebate amount. For windows and doors specifically, you can receive up to $5,000 in rebates - $250 per ENERGY STAR certified window (maximum 10 windows) and up to $1,500 for exterior doors. The products must meet specific performance criteria, including a U-factor of 1.22 or lower for windows in Ottawa's climate zone.

Important timing considerations: You must register for the program and complete your pre-retrofit evaluation before purchasing or installing any products. The evaluation report is valid for 18 months, giving you time to plan and complete your upgrades. Many Ottawa homeowners combine window replacement with other eligible upgrades like insulation or heat pumps to maximize their rebate potential.
