Mayor's Energy Challenge

Do you own or manage a building in King that is over 50,000 square feet?

If you do, then please join me by taking part in the Mayor's Energy Challenge!

In King Township, we have always demonstrated a commitment to sustainability, and that means planning ahead.  By monitoring your building's energy and water use, you will be able to make good decisions on how to improve your building's efficiency and inherently save money. Which means your building will reduce energy use, and reduce the greenhouse gas emissions associated with powering your building.

Monitoring your building's energy use is actually a requirement of our Provincial Government, so here in York Region, we decided to turn it into a friendly competition between the nine municipalities.

Let's make King a shining example of sustainability by being the first to get to 100% participation!

What is the Ontario EWRB Program?

Ontario’s Energy and Water Reporting and Benchmarking (EWRB) program is a provincial requirement designed to help building owners and managers make decisions on how to improve their building’s efficiency and inherently save money. A take away from the decisions you make as a building owner to reduce energy and save money is reducing the greenhouse gas emissions associated with powering your buildings.

 Properties that must take part in the EWRB program are commercial, industrial or multi-unit residential buildings over 50,000 square feet. The mandatory reporting deadline is July 1, 2020. Full details on the Ontario regulation can be found at the EWRB Guide.

What are the Benefits of Taking Part in this Program?

Organizations benchmarking consistently in Portfolio Manager have achieved average energy savings of 2.4% per year!

Once you have benchmarked your building’s energy and water, you will have the ability to:

  • Establish a baseline for measuring improvement in consumption.
  • Set a target to reduce greenhouse gas emissions.
  • Reduce operating costs over the long term.
  • Improve energy and water conservation awareness among building owners, tenants and visitors.
  • Participate in green building certificate programs and other sustainability initiatives.

Important Updates

For the 2020 reporting year, the Government of Ontario will accept the submission of data to the EWRB initiative until October 1, 2020.

Please note that the ministry has amended O. Reg. 506/18 to delay the roll-out of the Energy and Water Reporting and Benchmarking initiative to buildings between 50,000 and 100,000 square feet until 2023, allowing three additional years for small building owners to prepare for reporting their energy and water usage data.


The website has a reporting checklist and guide.

For more information on how to report your buildings energy and water consumption, visit Guide to Energy and Water Reporting. To update your building’s reporting lead contact information, click here.

Additional Information

Ontario’s Ministry of Energy Northern Development and Mines will distribute program instructions via mail in early 2020.  King Township staff will be reaching out, where possible to building owners to explain the program and answer any questions owners may have.

If you have questions visit or call 289-648-4107 for further details, free of charge.
