On April 1, 2024, Enbridge Gas adjusted the rates customers pay to reflect changes in the expected market price of natural gas supplies and transportation services. We buy these items from the market and adjust the related rates every three months (January, April, July and October). This current rate change reflects changes in expected costs to store natural gas and deliver it to customers through our distribution system in 2024. Delivery rates are set once a year, subject to approval by the Ontario Energy Board, which conducts a public review process.

These rate changes are effective as of Jan. 1, 2024 and will be recovered from customers between May 1 and Dec. 31, 2024.

Enbridge Gas adjusts customer delivery rates to reflect the expected costs to deliver natural gas safely and reliably to Ontario homes and business. Following the 2024 cost of service application, the OEB approved the fair and reasonable regulated distribution, transmission and storage rates that Enbridge Gas will charge customers in 2024 to recover the costs of serving our customers safely and reliably.

The costs of delivering natural gas to customers is recovered in our customer charge and delivery charges. The customer charge has increased to partially recover some of the fixed costs associated with maintaining a safe and reliable natural gas distribution system in 2024. For Rate 1, Rate M1 and Rate 01 the monthly customer charge has also increased to recover a redistribution of costs from the delivery to you charge to the monthly customer charge. This has resulted in a corresponding decrease in our 2024 delivery charges for these rate classes.

Different areas of the province are served by a different mix of natural gas transportation pipelines and gas supply sources, and as such, the costs for Enbridge Gas to buy gas supplies and transportation services from the market vary by location. In addition, the costs to build and maintain a distribution pipeline system varies by the geographic location for several reasons including different soil conditions (e.g. rockier soil in the north), population density and the distance between homes/businesses and the need for and timing of infrastructure expansions and maintenance. These costs differences are reflected in the four geographically based rate zones.

You’ll see two general types of natural gas rate changes during the calendar year. The first type occurs quarterly, on the first of January, April, July and October, to reflect changes in what Enbridge Gas expects to pay for gas commodity and transportation services, as well as differences between forecast and actual costs for prior periods. This is shown as a change in the gas commodity and transportation rates on your bill and may also appear as a small change in delivery rates as Enbridge Gas also uses natural gas to power our delivery system. These changes, which are passed through to you without mark-up, help ensure that you’re billed at a rate that closely reflects the expected market price of gas.

The second type of rate change occurs annually and reflects the overall costs to run a safe and reliable natural gas distribution system. This may include a change in the delivery or storage rates, or the customer charge, depending on your location.

In addition, as part of the federal government's carbon pricing program, a carbon charge applies to fossil fuels sold in Ontario, including natural gas. The federal carbon charge increases annually each April.

All rate changes are approved by the Ontario Energy Board.
