EWRB Reporting

Energy and Water Reporting and Benchmarking for Large Buildings

Ontario Regulation 20/17 under the Green Energy Act, 2009 for Energy and Water Reporting and Benchmarking (EWRB), requires owners of large buildings with a gross floor area of 50,000 square feet and above to report their energy consumption and water use data to the Ministry of Energy on an annual basis.

This regulation applies to privately-owned  buildings that are 50,000 square feet or larger, including commercial buildings, multi-unit residential buildings (with more than 10 units), and some industrial buildings (such as warehouses and industrial condominiums).

To learn more about whether the EWRB regulation applies to your building, and how and when to report your data, consult Ontario Regulation 20/17 and visit Ontario.ca/energyreporting.

Requesting your data from Halton Hills Hydro

Commercial and Industrial Buildings Gross Floor Area: 50,000 square feet and larger

Multi-Unit Residential Buildings Gross Floor Area: 50,000 square feet and larger

Please use the form below to request the annual electricity consumption data for your property from Halton Hills Hydro. Remember to submit your data request as soon as possible. Requests may take up to four weeks to process from the receipt of this form. Requests received after June 1 may not be processed by the July 1 deadline.

Step 1: Gather the Necessary Information

Before we can provide the energy consumption data for your building, we will need the following information:

  • Ontario EWRB ID — a unique number provided by the Ministry of Energy & Electrification to large building owners
  • The assessment roll number and property code for your building — information which you can find on your property assessment and tax bill, or the Municipal Property Assessment Corporation (MPAC) website
  • Gross floor area of the building for which you are requesting the energy consumption report

If you are a property manager, energy consultant or other third party requesting energy consumption data on behalf of a property owner, the owner must complete and sign the authorization of this form in order to authorize Halton Hills Hydro to release the data to you. Halton Hills Hydro cannot process a request from a third party if that section isn’t completed and signed.

Step 2: Complete and Submit This Form
