Efficient renovation - Small buildings

This grant aims to encourage making renovations that will improve the thermal envelope of small buildings that consume less than 150,000 m³ of natural gas per year. By being better insulated, your building will consume less energy. 

The work may include replacing windows and/or improving the insulation of walls or roofs.

How to determine your annual natural gas consumption?
  • For existing customers: Check your last bill or consult your customer account under the Customer Space on our website.
  • For future customers: Contact us for an estimate of your future consumption. 

Calculation of grant¹

For windows: $30 per square metre of eligible windows replaced up to a maximum of 7.5%  of the cost of purchase and installation of the new windows.
