Large Building Energy and Water Reporting and Benchmarking (EWRB)

Starting in 2018, certain large building owners will need to report their building’s energy and water use annually. Under Ontario Regulation 20/17, water, electricity and natural gas utilities must make whole building consumption data available to building owners when requested.

Is your utility ready? Do you know the EWRB reporting requirements and what you will need to do to respond to building owners’ requests for consumption data?

Please visit for more information about the EWRB initiative. If you have questions on responding to building owners’ requests for water consumption data, please email or call 1-844-274-0689.
