Business Rates and Charges

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 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 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.

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.

The OEB approved a rate adjustment (Rider E) to reflect changes to Enbridge Gas' 2024 rates for the period of Jan. 1, 2024 to Dec. 31, 2024. These rates will be applied to customers’ bills from Jan. 1, 2025 to Dec. 31, 2025. For a typical residential customer this will result in a charge of approximately $1.14 to $1.52 (depending on location) that will be included in the Delivery to You, Transportation to Enbridge and Gas Supply Commodity sections. The total impact on your bill will depend on your usage.

The OEB has also approved a rate adjustment to reflect the clearance of the 2023 federal carbon deferral and variance account balances. This will appear as a one-time adjustment on customers’ April bills, and for a typical residential customer this will be a charge of approximately $0.85-$2.13, depending on your location.
