A new regulatory framework for measuring and monitoring the energy performance of Québec’s building stock took effect on July 8, 2026, under the Regulation respecting the mandatory reporting of the environmental performance of certain buildings (the “Regulation”).
Owners of certain categories of buildings must now prepare to annually report the energy consumption of their buildings under a new mandatory disclosure and verification regime that will be phased in starting January 1, 2027, and could apply to tens of thousands of buildings across Québec.
Background
The Regulation aims to enable Québec’s environment ministry (Ministère de l’Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs) to obtain more comprehensive data on the energy consumption of large buildings in order to support the energy transition of Québec’s building stock. With this Regulation, Québec joins several North American jurisdictions that have already adopted similar reporting
