The price of diesel fuel in Nova Scotia is a controversial topic. The price is determined by a formula that takes into account the price on the New York Mercantile Exchange, a wholesale margin, a transportation allowance, and a retail margin. Prices fluctuate weekly, and there is a federal excise tax of 6 cents per litre of diesel. The average price of diesel in Nova Scotia from 9 December 2024 to 17 March 2025 was 1.87 per litre, with a minimum of 1.73 and a maximum of 1.99. Some critics argue that this pricing method is not in the public interest and promotes higher prices and a lack of competition.

What You'll Learn

Diesel fuel prices are based on the New York Mercantile Exchange
The price of diesel fuel in Nova Scotia is based on the New York Mercantile Exchange (NYMEX) as a benchmark in Canadian funds. This price is used as a baseline and then additional costs are factored in, such as a wholesale margin, transportation allowance, and retail margin. These additional costs can vary depending on the specific zone within Nova Scotia, with six zones in total. The price of diesel fuel can change every Friday, depending on the market price over the previous seven days. An "interrupter" formula is also used to determine if the market prices have changed enough to warrant an immediate price adjustment.
NYMEX is a part of the CME Group, which is the world's leading derivatives marketplace. It offers futures contracts for various transportation fuels, including heating oil and, more recently, Used Cooking Oil (UCO) and Used Cooking Oil Methyl Ester (UCOME) to support the transition to greener energy. NYMEX has a high volume of trading, with an average of over 180 million barrels of heating oil traded daily and its futures traded in 94 different countries.
The price of diesel fuel in Nova Scotia is influenced by several factors, including the Federal Excise Tax, which is 6 cents for diesel fuel. The Harmonized Sales Tax in Nova Scotia is also charged at a rate of 15%, which is higher than in some other provinces. These taxes and the market price determined by NYMEX all contribute to the final price of diesel fuel that consumers pay at the pump in Nova Scotia.
While the NYMEX price is a significant factor in diesel fuel pricing in Nova Scotia, there are critics of this method of controlling petroleum product prices. Some argue that a different system, such as the one used in Prince Edward Island, could result in lower prices and allow for more competition. However, it's important to consider the unique characteristics of each province and their impact on pricing structures.
The price of diesel fuel in Nova Scotia, as of February 2025, appears to be around 134.3 to 137.3 cents per liter, based on user-submitted prices on GasBuddy.com. These prices may vary across different gas stations and locations within the province.

Wholesale margin, transportation allowance, and retail margin
The price of diesel fuel in Nova Scotia is determined by various factors, including wholesale margin, transportation allowance, and retail margin. These components play a crucial role in the overall pricing structure and are interconnected in complex ways. Let's break down each of these elements to understand their impact on diesel fuel pricing:
Wholesale Margin:
Wholesale margin refers to the difference between the wholesale gasoline price and the market price for crude oil. In simpler terms, it represents the costs and profits incurred by refining companies. The wholesale gasoline price is calculated by taking the average of branded and unbranded wholesale prices at various wholesale fuel loading racks across the state. Branded gasoline is fuel sold under a brand name, such as BP, Shell, or Exxon, while unbranded gasoline lacks this association. The wholesale price includes the costs of refining, terminal operations, crude oil processing, storage, and other associated expenses.
Transportation Allowance:
While not a separate line item in fuel pricing, transportation allowance is an essential component of the distribution margin. The distribution margin includes various transportation costs, such as shipping the refined product to retail stations and delivering it to end consumers. These transportation costs are factored into the overall distribution margin, which also covers distribution costs, marketing costs, and profits.
Retail Margin:
The retail margin, also known as the distribution margin, is calculated by subtracting the wholesale gasoline price, taxes, and other applicable fees from the weekly average retail sales price. This margin includes the costs and profits of operating a retail gas station, encompassing expenses such as rent, labour, utilities, and any additional services offered to customers. A positive distribution margin indicates profitability, while a negative distribution margin suggests that gasoline is being sold at a loss.
The interplay between wholesale margin, transportation allowance, and retail margin influences the final price of diesel fuel in Nova Scotia. These components reflect the costs incurred at different stages of the fuel supply chain, from refining to distribution and retail. By understanding these margins, consumers can gain insight into the complex pricing dynamics of the diesel fuel market in Nova Scotia and make more informed decisions regarding their fuel purchases.

Federal Excise Tax
The price of diesel fuel in Nova Scotia is influenced by various factors, including the price on the New York Mercantile Exchange, wholesale and transportation costs, and retail margins. Additionally, there are taxes that impact the final price of diesel fuel.
One of the taxes applicable to diesel fuel in Nova Scotia is the Federal Excise Tax. This tax is levied by the federal government on certain goods and services, including diesel fuel. In the context of diesel fuel in Nova Scotia, the Federal Excise Tax amounts to 6 cents per litre. This tax is separate from the provincial taxes and other charges that may apply.
The Federal Excise Tax is a component of the overall fuel taxation in Canada. Canada, like most countries, imposes excise taxes on gasoline, diesel, and other liquid and gas motor fuels. These taxes are often referred to as fuel taxes and are applied at different administrative levels. The federal government collects these taxes to generate revenue and, in some cases, to influence consumer behaviour or promote specific policy objectives, such as reducing pollution.
In addition to the Federal Excise Tax, there is also a Federal Fuel Charge (FFC), commonly referred to as the Carbon Tax, which went into effect in Nova Scotia on July 1, 2023. This charge is mandated under the Greenhouse Gas Pollution Pricing Act and is applied to various petroleum products, including diesel fuel. The specific rate of the Federal Fuel Charge may vary depending on the type of fuel and is subject to changes over time.
It is worth noting that there are exemptions and relief mechanisms in place for certain individuals and organizations regarding the Federal Fuel Charge. For example, eligible individuals can receive the Climate Action Incentive Payment (CAIP), which is a tax-free amount designed to offset the cost of federal pollution pricing. Additionally, specific fuel consumers, such as commercial fishing vessels, may qualify for exemptions or reduced tax rates under certain programs, such as the Fuel Tax - Consumer's Exemption Permit. These exemptions and rebates help to alleviate the financial burden of fuel taxes for specific groups.

The Provincial Sales Tax
As of June 2023, the price of diesel in Nova Scotia ranges from $2.17 to $2.35 per litre, including federal and provincial taxes. This price is relatively high compared to the price of diesel in other provinces and is primarily attributed to the Provincial Sales Tax (PST) and the federal goods and services tax (GST).
The PST rate in Nova Scotia has been relatively stable in recent years, with no changes to the standard rate since 2010. However, certain exemptions and special rates may apply under specific circumstances. For example, a lower PST rate is applied to certain heating fuels, aiming to reduce the tax burden on residents during the colder months.
Additionally, some purchases may be exempt from PST. These exemptions often apply to essential goods and services, and in the context of fuel, certain industries or sectors may benefit from exemptions. For instance, diesel fuel used for agricultural purposes may be exempt from PST, recognising the unique needs of the agricultural sector. It is important to be aware of these exemptions and special rates, as they impact the overall cost of purchases.

Average diesel price in Nova Scotia
The price of diesel fuel in Nova Scotia is based on the price on the New York Mercantile Exchange (NYMEX) as a benchmark in Canadian funds. This price includes a 6-cent-per-litre wholesale margin, a transportation allowance of 0.5 to 2 cents per litre, and a retail margin of 4 to 5.5 cents per litre. The transportation allowance is calculated based on six zones in Nova Scotia, with Zone 1, including the Halifax Regional Municipality, having the lowest transportation cost at 0.5 cents per litre, and Zone 3, including Western Annapolis, Digby, Yarmouth, Shelburne, and Queens counties, having a transportation cost of 1.4 cents per litre.
In addition to these base costs, a Federal Excise Tax of 6 cents per litre is added for diesel fuel. The final price of diesel can vary depending on other factors, such as the interrupter formula, which is based on market prices and can trigger a price change if the 5-day average NYMEX spot price changes by ±4 cents per litre from the last average used to set the scheduled price change.
As of March 2025, the average diesel price in Nova Scotia over the previous four months (since December 2024) was 1.87 per litre, with a minimum of 1.73 in December 2024 and a maximum of 1.99 in January 2025.
It is worth noting that Nova Scotia charges a Harmonized Sales Tax of 15%, which contributes to higher gasoline prices compared to other provinces like Prince Edward Island, which does not charge Provincial Sales Tax.
