Are there any financial incentives when building a new house to make efficient?

Building a new home in Ontario opens up several financial incentives that reward high-performance construction. While many grants focus on retrofitting older homes, new builds can access significant savings through mortgage insurance refunds and tax rebates. Read more about available programs here -

The most accessible program is the CMHC Eco Plus, which offers a 25% partial refund on mortgage insurance premiums for homes certified as energy-efficient. Additionally, the Ontario New Housing Rebate provides a refund of the provincial portion of the HST, which can be worth up to $24,000 depending on the purchase price.

Local utilities like Enbridge Gas also offer "Savings by Design" programs for builders to encourage energy modeling and better envelope design. These incentives often help offset the higher upfront cost of high-performance materials like triple-pane windows or continuous exterior insulation. Taking advantage of these programs early in the design phase ensures you don't leave money on the table.
