Petroleum Prices - Questions and Answers

How are the maximum prices established?

STEP 1: Calculating the Benchmark Price: Benchmark prices for refined petroleum products are based on the average prices on international markets where the product is sold in significant volumes. For motor fuels and furnace oil, the benchmark price is based on the average New York Harbour Price. The benchmark prices for mid-grade and premium gasoline include mark-ups established by Regulation. In the case of propane, the Sarnia, Ontario market price is used.

The Board calculates weekly benchmark prices based on the average of its daily reference prices for the seven-day period, excluding the weekend, since the benchmark price of that petroleum product was last published.

STEP 2: The Wholesale Margin is added: The maximum wholesale margin is added to the benchmark price. The maximum wholesale margin is 6.51 cents per litre for each type of motor fuel, 5.5 cents per litre for furnace oil and 25.0 cents per litre for propane.

STEP 3: The Cost of Carbon Adjustor is added: The cost of carbon adjustor for motor fuels is added to the other prices. The cost of carbon adjustor is a monetary adjustment intended to mitigate the added costs for petroleum wholesalers and retailers to comply with federal carbon intensity standards imposed by the Clean Fuel Regulations under the Canadian Environmental Protection Act.

The cost of carbon adjustor only applies to motor fuels.

STEP 4: Taxes are added: Once the benchmark price, the maximum wholesale margin, and the cost of carbon adjustments are added together, all applicable taxes and fuel charges are applied. In the case of motor fuels, this includes the federal excise tax, the provincial gasoline and motive fuel tax, the federal fuel charge, and the harmonized sales tax (HST). For heating fuels, only the federal fuel charge and HST is added. This results in the maximum wholesale price.

STEP 5: Setting the Maximum Retail Price: The retail margin is added to the maximum wholesale price. The maximum retail margin is 8.46 cents per litre for each type of motor fuel. In the case of full-service motor fuels, the retailer may also charge up to an additional 3.0 cents per litre. The HST is then applied to the retail mark-up to produce the maximum retail price.

The process is the same for furnace oil and propane except that the maximum retail margins are higher. For furnace oil, the maximum retail margin is 27.21 cents per litre; for propane, the maximum retail margin is 25.0 cents per litre.

STEP 6: Adding the Delivery Cost: Wholesalers are allowed to recover the actual cost of delivering petroleum products to various parts of the province, up to a maximum of 3.75 cents per litre for motor fuels.

On Grand Manan Island, the maximum delivery cost is 5.0 cents per litre. Retailers are allowed to pass these delivery costs on to consumers.

The maximum delivery cost for furnace oil is 5.0 cents per litre, and for propane, it is 10.0 cents per litre.

The HST is then applied to the maximum delivery cost for each fuel type.

STEP 7: Market Adjustor: The market adjustor has been set at 0.00 cents per litre as of December 20, 2022.  It will be reset following a process that will be established by the Board.

What are the cost of carbon calculations?

STEP 1: Determine the clean fuels regulation credit price

California LCFS credit USD / tonne A TBD Note 1
California low carbon fuels intensity target gCO2e/MJ B TBD Note 2
California renewable diesel carbon intensity gCO2e/MJ C TBD Note 3
Difference gCO2e/MJ D = B - C    
California renewable diesel energy density MJ / litre E 34.25 Note 4
Conversion factor   F 1,000,000 Note 5
Exchange Rate (weekly)   G TBD Note 6
Low carbon fuels standard credit price $CDN / litre H = A*D*E/F*G    
D4 RIN Value USD / US gallon I TBD Note 7
Renewable diesel RIN eqivalence value USD / US gallon J 1.7 Note 8
Exchange Rate (weekly)   G TBD Note 6
Conversion US gallon to litres   K 3.78541  
D4 RIN Price $CDN / litre L = I*J*G/K    
Interim clean fuel credit price $CDN / litre M = H + L    

STEP 2: Convert the credit price per litre calculated in Step 1 to a credit price per tonne

Clean Fuels Regulation liquid class reference carbon intensity gCO2e/MJ N TBD Note 9
Clean Fuels Regulation renewable diesel default carbon intensity gCO2e/MJ O 35 Note 10
Incremental carbon intensity gCO2e/MJ P = N - O    
Clean Fuels Regulation renewable diesel energy density MJ / litre Q 34.921 Note 11
Conversion factor   F 1,000,000 Note 12
CFR credit price per tonne $CDN / tonne R = M/P/Q*F    

STEP 3: Apply the CFR adjustor from Step 2 by fuel type (ULSD & gasoline)

Clean fuels regulations default (baseline) carbon intensity gCO2e/MJ S 95.00 93.00 Note 13
Clean fuels regulations target gCO2e/MJ T TBD TBD Note 14
Incremental gCO2e/MJ U=S-T 3.5 3.5  
Clean fuels regulation energy density MJ / litre V 34.69 38.65 Note 15
Conversion factor   F 1,000,000 1,000,000 Note 5
Proposed Cost of Carbon Adjustor $CDN / litre W = R*U*V/F
