On February 16, 2021 the Province approved and ordered Amendment 7 to the Energy Efficiency Standards Regulation. Amendment 7 includes updated standards for residential windows and sliding glass doors that were proposed and consulted on in 2019.

The new standards for residential windows and sliding glass doors are summarized below. For detailed information, please see the Residential Windows and Sliding Glass Doors Regulatory Bulletin.
