Reporting for buildings 100,000 square feet and larger concludes on July 1, 2019

The Ontario Benchmarking Help Centre is here to assist Ontario building owners report their building utility usage under Ontario's Energy and Water Reporting and Benchmarking (EWRB) initiative.

Once fully phased in by 2020, most owners of commercial, industrial, multi-unit residential and other building types that are 50,000 square feet and larger are encouraged to report their building's energy and water consumption annually to the province.

Reporting Timetable

Year of Reporting Property Size and Type
2018 Buildings 250,000 ft2 and larger (excluding multi-unit residential)
2019 Buildings 100,000 ft2 and larger (including multi-unit residential)
2020 Buildings 50,000 ft2 and larger (including multi-unit residential)
  • Reports are always due by July 1.
  • Your report must cover details about the previous calendar year.
  • For example, a report for water and energy used from January to December 2018 would be due by July 1, 2019.

Why measure energy and water use?

Large buildings, such as offices, condominiums and retail stores, play an important role to fight climate change and cut greenhouse gas pollution.

In 2013, these types of buildings accounted for 19 per cent of Ontario's total greenhouse gas emissions.

Save money by tracking your building's energy and water use

Track where and why your building is wasting energy and water.

Identify energy and water efficiency opportunities.

Gain over $11,000 in cost savings per year with as little as 2.4% annual energy savings.

Get valuable feedback by comparing your building's energy and water use to similar buildings

Did you know?

  • The average Canadian office building benchmarked in Portfolio Manager is 17,800 m2 and uses 21,300 gigajoules (GJ) of energy per year at a cost of about $22/GJ.
  • Organizations benchmarking consistently in Portfolio Manager have achieved average energy savings of 2.4% per year!
  • 2.4% annual savings means that building could save just over 500 gigajoules of energy in one year, representing cost savings of over $11,000.
  • Over the lifespan of the building (usually at least 50 years), this could produce cumulative savings of over $300,000.
  • Benchmarking and disclosure programs for privately owned buildings are becoming widespread in North America. In addition to Ontario, there are programs at the provincial, state or local level in California, Manitoba, New York, Vancouver, Chicago, Atlanta and others.
