Fuels price survey information

Toronto footnote 1 regular unleaded gasoline retail prices in Q3 2020 were 17.1 cents per litre (¢/L) lower than in Q3 2019. This was the result of lower crude oil costs (-12.5 ¢/L) and lower wholesale margins (-5.0 ¢/L), offset in part by higher retail margins (+0.1 ¢/L) plus applicable taxes (-0.2 ¢/L, or 2.2 ¢/L federal carbon tax footnote 2 minus 2.0 ¢/L HST). Crude oil costs would have fallen by 0.3 ¢/L more than they did, had it not been for a 1% decline in the value of the Canadian dollar relative to the Q3 dollar from Q3 2019 to Q3 2020. Canadian crude oil and wholesale gasoline costs are affected by the CDN/US exchange rate because these commodities are traded on a North American and international basis.

Note: Retail gasoline prices are affected by crude oil prices, wholesale gasoline prices, and competition in the local retail gasoline market. Prices vary from city to city because of differences in market size and structure, costs, and the degree of local competition.

Ontario’s OEB rate-regulated natural gas rate zones

A map showing areas with natural gas in Ontario.

A map showing the regions of Ontario with access to Ontario Energy Board rate regulated natural gas and where each rate zone is.

Ontario has five primary natural gas rate zones, which are rate-regulated by the Ontario Energy Board (OEB). Kitchener Utilities, and Utilities Kingston also operate in Ontario, but are not rate-regulated by the OEB.

Each quarter, OEB rate-regulated natural gas utilities adjust their gas supply charges based on a forecast of natural gas market prices over the next 12 months. Some components of these rates, such as the transportation charge, may change at the same time. Other components follow a different timeline, like delivery rates, which generally change once a year. Additionally, the “gas supply cost adjustment” is updated through the OEB's Quarterly Rate Adjustment Mechanism (QRAM), footnote 8 which captures any differences between forecast and actual commodity costs.

Following approval from the OEB, effective January 1, 2017, the price for the Union South Rate zone combined commodity and transportation costs into one gas supply charge going forward. For consistency of reporting, storage and transportation costs have been included in this section for all rate zones. footnote 9 Prices listed in this section do not include: the monthly customer charge, the federal carbon tax, delivery charges, or any System Expansion Surcharges.

Effective October 1, 2018, the OEB removed provincial cap-and-trade costs in conjunction with the QRAM for Q4 2018. The removal of cap-and-trade costs resulted in a reduction of about 3.3 ¢/m3 from the delivery charge component of natural gas bills.

Effective January 1, 2019, Enbridge Gas Distribution (EGD) and Union Gas (Union) amalgamated to become Enbridge Gas Inc., however EGD and Union will continue to operate as distinct rate zones for the immediate term.

On April 1, 2019, the federal carbon tax came into effect at a rate of 3.91 ¢/m3 for natural gas. Effective August 1, 2019, the OEB approved the collection of the federal carbon tax through a new line item on natural gas bills. The federal carbon tax was therefore absent from Ontario natural gas bills during Q3 2019. Effective April 1, 2020, the federal carbon tax increased to 5.87 ¢/m3 for natural gas.

In light of economic pressures from the COVID-19 pandemic, the OEB granted Enbridge a deferral to its July 1, 2020 QRAM application and postponed commodity cost increases. Enbridge customers did not see changes to their natural gas rates for Q3 2020. EPCOR did not seek such a deferral, and EPCOR customers saw slight decreases to their bills effective July 1, 2020.

Ontario natural gas storage balances

Monthly closing inventories in Ontario (PJ)

A line graph showing closing inventory of natural gas in Ontario.

Note: Previous editions of this table featured total Eastern Canadian storage levels in billion cubic feet (bcf) and million cubic meteres (mcm).

This line graph displays Ontario natural gas storage balances every quarter from Nov 2016 to Aug 2020.

In Ontario, natural gas is stored primarily at Dawn, ON.

According to seasonal patterns, storage levels normally peak in late October or early November as withdrawals for natural gas heating begin to outpace storage injections. Prices are also more likely to see a cyclical rise during the winter heating season. Utilities buy a certain amount of natural gas during the summer months when the price is cheaper. The supply is stored, and then delivered to customers during the colder months.

Average Monthly Natural Gas Bills

While natural gas prices are set quarterly, natural gas customers are billed on a monthly basis. As natural gas consumption patterns change from month to month, so too does the size of a customer's natural gas bill. Therefore, while natural gas rates stay the same over a three month period, the size of the bill can vary based upon the level of consumption, with seasonality being the greatest factor (i.e., heating demand during periods of cold weather).

The natural gas bill for a residential customer in Ontario has five primary components:

  • Customer Charge: a fixed charge that is typically set annually, and is the same every month, regardless of the level of consumption;
  • Gas Supply: a volumetric charge based upon consumption, set quarterly;
  • Delivery Charges: volumetric charges based upon consumption, typically set annually;
  • Federal Carbon Charge (FCC): a volumetric charge based upon consumption, set annually by the federal government; and
  • Harmonised Sales Tax (HST): a 13% tax on the retail price (i.e., the combination of all charges mentioned above).

Propane Market

Ontario’s propane market is not subject to economic regulation or oversight by the Ontario Energy Board (OEB). Wholesale propane commodity prices are determined in a competitive, integrated North American market. In Ontario, propane distributors compete to supply end-users and retail prices are set through transactions between a distributor and a customer based on a number of factors including: local supply and demand; time of year; and transportation costs.

Mont Belvieu, Texas is the benchmark pricing point for North American propane markets, as it is the largest producing region.

Sarnia has significant underground storage infrastructure for propane and is a wholesale storage and trading hub for propane markets in Eastern Canadian and the U.S. Great Lakes region. Demand for propane is highly seasonal so storage inventories are replenished in the summer months to be drawn upon for the next winter heating season.

Similar to natural gas, propane prices tend to decrease in the summer months, and increase in the winter heating season. The length and severity of the winter will typically have a corresponding impact on the price of propane.

Due to the unregulated nature of the propane market and limited pricing data from private sector suppliers, ENDM does not maintain historical retail prices for the residential propane market.
