The overall impact of these changes will depend on how much gas you use and whether you purchase your gas from a gas marketer.

Delivery and storage rates are reviewed and approved by the Ontario Energy Board, which conducts an open review process with participation from consumer groups and Ontario municipalities.

Please visit our business rates section to view the rates specific to you and your location.

Gas costs – Gas commodity costs include information on the “Gas Supply Charge” and “Cost Adjustment” lines on your bill. The net natural gas rate reflects what we expect to pay for gas supplies and transportation services during the next year as well as any adjustments to make up the difference between our forecast cost for gas and actual costs from prior periods. Also, in the Union South rate zone (Rate M1 and M2), the cost of transportation to Ontario is included in the “Gas Supply Charge”.  

Transportation costs – Transportation costs include information on the “Transportation to Enbridge” and “Cost Adjustment” lines on your bill and reflect the cost of transporting natural gas into Ontario from its North American sources.

Transportation costs vary depending on where you live due to changing fuel prices, pipeline tolls and available capacity on pipelines serving different parts of Ontario. For customers in the Union South zone (Rate M1 and M2), the transportation cost is included in the “Gas Supply Charge” line on your bill.

Delivery costs – Delivery costs include information on the “Delivery to You” line on your bill and reflect the cost of delivering natural gas to your home or business as well as an adjustment to make up the difference between our forecast and actual delivery rates from prior periods, through our safe and reliable distribution system. This charge also includes a facility carbon charge which is associated with the costs to operate Enbridge Gas’ facilities to deliver natural gas to you. Storage and load balancing costs are also included in the “Delivery to You” line item and reflect the cost of storing natural gas so it is available when you need it.

Customer Charge – The customer charge partially covers the cost of maintaining a safe and reliable natural gas distribution system. It includes things like meter reading, customer services and 24-hour emergency response. 

Rate Adjustment – There are no prior‑period cost adjustments reflected in the April rate filing.

Because natural gas is a commodity, the market price can fluctuate with changes in the amount of readily available supply or in the level of demand for the product. We adjust customer prices for market fluctuations every three months to reflect changes in the market price. The decrease in rates is driven primarily by lower North American natural gas market prices and healthy storage levels, which have reduced the overall cost of natural gas supply. Enbridge Gas’ integrated system and long‑term planning also allow the company to manage these market fluctuations reliably, ensuring customers benefit when market conditions improve.

The federal carbon charge was removed from Enbridge Gas customer bills effective April 1, 2025.

A facility carbon charge is included in the delivery or transportation charge on the bill. This charge is associated with the costs to operate Enbridge Gas’ facilities that deliver natural gas to you. In January, there was an increase in the facility carbon charge from 0.0123 cents/m³ to 0.0145 cents/m³. For an average residential customer, this increase represented about 32-35 cents annually, depending on your location.

There are no prior‑period cost adjustments reflected in the April 2026 rate filing.

Enbridge Gas buys natural gas at a number of market supply hubs in Western Canada and the U.S. We pay market prices for natural gas and then pay other pipeline companies to transport the gas from supply hubs into our distribution system in Ontario. We adjust the rates we charge our customers for these items quarterly to reflect changes in market prices, which are passed through to our customers without mark-up. In addition, there are adjustments for the difference between our forecast for natural gas and natural gas transportation market prices, storage and distribution costs and the actual costs from prior periods.

The rates we charge customers for natural gas and gas transportation services are based on a forecast of the prices we expect to pay to buy these items from the market. Because the actual market costs can differ from our forecasts, adjustments are sometimes made quarterly (Jan. 1, April 1, July 1 and Oct. 1) to either refund or collect the difference so that you only pay the actual costs for these services and nothing more. Any costs are passed on to customers without any mark-up, subject to OEB review and approval.

Enbridge Gas sets rates based on a forecast of the costs we expect to pay for natural gas supplies and transportation and then adjusts rates for the actual costs each quarter. 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. Any 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.

All rate changes are approved by the Ontario Energy Board.

If you buy natural gas and/or transportation services from an energy marketer, the price you pay for your gas supplies and/or transportation depends on the terms of the contract and is excluded from this rate change. If you have questions about their charges, please contact them directly at the number found on your bill. For other services purchased from Enbridge Gas (natural gas transportation, storage and delivery), residential customer rate changes depend on your location.

The pressure elevation factor (PEF) is a value that helps ensure accurate billing. Natural gas expands when the atmospheric pressure is low and contracts when it's high. Atmospheric pressure changes depending on land elevation. However, meters that measure natural gas consumption don't always adjust for atmospheric pressure.

PEF is applied to the amount of gas you use to compensate for how gas reacts at different elevations to ensure you are only being charged for the gas you consume.

Your pressure elevation factor (PEF) can make your energy bill go up or down.

Here are two examples of how it works, based on average household usage. The exact amount will depend on your specific usage.

1. A household that uses 2,400 cubic metres of gas annually in Toronto has a PEF of 1.0057. This means their consumption will increase by approximately 14 cubic metres annually.
2. A household that uses 2,400 cubic metres annually in Barrie will have a PEF of 0.9904. This means their consumption will go down by approximately 23 cubic metres annually.

The pressure elevation factor (PEF) value for your account can be found on the lower right-hand corner of the first page of your gas bill or through My Account by clicking on the question mark next to the amount of gas used under the Charges for Natural Gas.
