Frequently Asked Questions about Rate Changes

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.

Business customers who buy natural gas from Enbridge Gas will see a decrease in their natural gas bills ranging from about 1.1 percent to 11.7 percent per year, depending on location. The overall impact of these changes will depend on how much gas you use and whether or not 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.

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. A warmer than normal winter season and healthy supply and inventory levels have contributed to this market price decrease. We adjust customer prices for market fluctuations every three months to reflect changes in the market price.

Enbridge Gas adjusts the rates customers pay for natural gas every three months (subject to OEB approval), based on a forecast of what we expect natural gas market prices will be in the coming months. We then adjust for the difference between our forecast and actual costs from prior periods through a quarterly cost adjustment. In some rate zones, this adjustment will result in an overall bill decrease.

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.

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.

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 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 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. These costs are passed on to customers without any mark-up. The October cost adjustment change will result in some customers seeing an overall bill decrease.
