Changes implemented February 2018

Registration under LEED® Canada rating systems is closed; projects must submit for certification by October 31, 2022. New projects must register under LEED v4.

The LEED® Canada for Existing Buildings: Operations & Maintenance (EB:O&M) rating system helps building owners and operators measure operations, upgrades and maintenance on a consistent scale, with the goal of maximizing operational efficiency while minimizing environmental impacts. LEED® EB:O&M addresses whole-building cleaning and maintenance issues (including chemical use), recycling programs, exterior maintenance programs, and systems upgrades.

LEED® EB:O&M is a globally recognized rating system with rigorous energy requirements that result in top performing buildings and reduced GHG emissions. Along with the economic and environmental benefits, LEED’s requirements increase occupant comfort and satisfaction by delivering healthier buildings with more daylight, better air quality and improved temperature control.


Buildings are operated and maintained for decades and therefore, under this rating system, certified buildings must file for recertification at least once every five years to maintain their LEED O+M status.

As recertification requires demonstration of compliance for the entire period of time from the project's previous certification, LEED O+M represents an ongoing commitment by building operators to continuously assess the environmental performance of their buildings.
