​EPCOR has applied to the Ontario Energy Board to increase its natural gas rates, effective January 1, 2024. If the application is approved as filed, the amount EPCOR charges a typical residential customer and a typical commercial customer in its Aylmer service area would increase by the following yearly amounts:​

  • General Service Residential: $30.08 per year​

  • General Service Commercial: $100.22 per year​

The requested rate increase is set using an OEB-approved formula which is tied to inflation and other factors intended to promote efficiency. The rate increase also includes EPCOR's request to dispose of the balances in certain deferral and variance accounts.​

Other customers may also be affected. It is important to review the application carefully to determine whether you may be affected by these changes.

The Ontario Energy Board will hold a public hearing

The Ontario Energy Board (OEB) will hold a public hearing to consider the application filed by EPCOR. During the hearing, which could be an oral or written hearing, the OEB will question EPCOR on the request for a rate increase. The OEB will also hear questions and arguments from individuals that have registered to participate (called intervenors) in the hearing. At the end of this hearing, the OEB will decide what, if any, rate change will be allowed.

The OEB is an independent and impartial public agency. It makes decisions that serve the public interest. Its goal is to promote a financially viable and efficient energy sector that provides customers with reliable energy services at a reasonable cost.
