Natural gas rates

Find out about natural gas rates for supply, and why they vary throughout the year.
Rates and your bill

As part of our mandate, we set the rates for the gas you use for your home or business if you're a customer of Enbridge Gas, Union Gas and EPCOR Natural Gas Limited Partnership. We also approve the rates these utilities charge to deliver natural gas to you. We do not set rates for Kitchener Utilities or Utilities Kingston.

We also do not regulate the prices that natural gas marketers charge in their contracts. Or what companies charge to rent, repair or maintain water heaters.

How often does the Ontario Energy Board set new rates?

We set rates for the natural gas that you use (supply) 4 times a year.

Natural gas is a commodity that is traded on North American markets. Market prices rise and fall based on current supply and demand. Major weather events can also affect the market price.

We don’t allow utilities in Ontario to earn a profit on the sale of gas. They must pass through to you the price they pay to buy natural gas on the open market, with no markup.

Every 3 months, natural gas utilities ask us to adjust their supply rates to cover:

  • Future costs. Utilities estimate how much gas they expect their customers to use, based on previous years. Then they estimate the market price for natural gas over the next 12-month period.
  • Past costs. Utilities also review the difference between what they previously forecast their customers would pay and what their customers actually paid. This may be called the Gas Price Adjustment or Cost Adjustment on your bill. It can increase or lower the rate accordingly. For example, if a utility collected more from customers than it paid for gas in the past, the difference is credited back to customers through a lower rate. Likewise, if not enough was collected by the utility, the rate will be higher.

Because forecasting is done so far in advance of when utilities actually purchase natural gas, it is never exact. We adjust supply rates periodically throughout the year so there’s less likelihood you or the utility will owe a large amount at a given time.

Have your say about gas delivery rates

Visit the current applications page to find out if your utility has applied to change your delivery rates. If so, you can:

  • See what they’re asking for and why, and provide your comments online.
  • Find out when upcoming community meetings and hearings are being held so that you can attend.
  • See documents related to the case.

How are rates affected by a change in the seasons?

Time of year is another factor affecting costs. Because natural gas is a main source of heating in North America, it is usually more expensive in the winter months. Most utilities buy what they think they’ll need, based on forecasts, during the summer when the price is cheaper. Then they store the supply until winter and deliver it when you need it to heat your home or business.

If the weather isn’t exactly as predicted, it can have a significant impact on your rates. For example, if the winter is colder or longer than expected, the utility may have to buy extra supply, likely at a higher cost. Because the utility passes on the actual cost of gas, this extra cost will need to be collected from customers. Similarly, if the price is lower than forecast, this would result in a credit to customers.

Natural gas rates effective July 1, 2019

Each utility has different supply rates. Delivery rates also vary based on several factors, including their operating costs. This chart shows supply rates for each of the 3 natural gas utilities whose rates we set.

July 1, 2019 natural gas rates

The OEB approved Enbridge Gas Inc.’s rates for the Union rate zones for July 1.

Natural gas rates are based on a forward looking forecast for the next 12 months. Forecasts are never perfect, so the billed price is normally either higher or lower than the actual market price. The difference is tracked and passed on to consumers as a credit or a charge in subsequent quarterly rate adjustment applications.

Effective July 1, 2019, the Gas Supply Charge (including gas supply cost quarterly adjustment) for the Union rate zones are:

Rate Zone

Natural Gas Price ¢/m3

Gas Price Adjustment ¢/m3

Effective Price ¢/m3

South Rate M1* 12.9301 3.3656 16.2957
North East Rate 01** 13.2125 3.8340 17.0465
North West Rate 01 10.4839 -0.9848 9.4991
* The commodity rates for Union South include all of the transportation costs. 
** The commodity rates for Union North East include a portion of the transportation costs.

 

In the South Zone, there has been a decrease in the price for natural gas and an increase in the Gas Price Adjustment. There have been no changes to transportation or storage prices. Residential customers in this service area will see an overall increase to their annual bills.

In the North East Zone, there has been a decrease in the price for natural gas and an increase in the Gas Price Adjustment.

The application also included an increase in the monthly customer charge of one dollar per customer for all of the rate zones, which gas utilities must collect from each of their customers to contribute towards the cost of eligible gas expansion projects to serve new communities (see section 36.2 of the Ontario Energy Board Act, 1998 and Ontario Regulation 24/19, which take effect on July 1, 2019). The impact of this increase is reflected in the total annual bill impact information presented below.

The application also included an increase in the monthly customer charge of one dollar per customer for all of the rate zones, to reflect the coming into effect of the government’s new program to help fund the cost of expanding access to natural gas to unserved communities (see section 36.2 of the Ontario Energy Board Act, 1998 and Ontario Regulation 24/19). The impact of this increase is reflected in the total annual bill impact information presented below.
