Oil from Canada supplies more than 23% of U.S. refinery feedstock, helping bolster North American energy security

Introduction

The refining industry¹ in the United States is one of the world’s largest, with capacity to process 18 million barrels of oil per day. Canada plays a crucial role by supplying more than one-fifth of the crude oil refined in the U.S.

The U.S.–Canada cross-border crude oil trade is essential to North American energy security. Canadian crude oil exports and the U.S. refinery industry are highly integrated. In recent years, Canada’s crude oil sector has been making a growing contribution to the operations of U.S. oil refineries.

U.S. refineries are converting Canadian crude oil, including heavy oil,² into products that North Americans use daily, such as transportation fuels (gasoline and diesel), chemicals, and plastics. Although the U.S. has increased its production of oil in recent years, U.S. refineries still rely on Canadian heavy crude oil to meet their feedstock (i.e., the raw materials and intermediate materials processed at refineries to produce finished petroleum products, otherwise known as refinery inputs) specifications.

In this CEC Fact Sheet, we examine several economic indicators that illustrate the importance of Canadian crude oil, particularly heavy crude, to U.S. refineries. This fact sheet also analyzes the refining industry’s direct and indirect economic impacts on the U.S. economy.

1. NAICS Code 324110 (Petroleum Refineries): This industry comprises
establishments primarily engaged in refining crude petroleum into refined petroleum.

2. A majority of the crude oil imported by the U.S. from Canada is heavy crude (between 15-25 API gravity). API gravity is a commonly used index for measuring the density of crude oil or refined products. Crude oil typically has an API between 15 and 45 degrees. The higher the API, the lighter the crude; the lower the API, the heavier the crude.

Imports of Canadian crude oil to refineries in the United States

The physical characteristics of crude oil determine how it is processed in refineries. Generally, heavy crude oil offers higher yields of low-value products (coke and asphalt) and lower yields of high-value products (gasoline). Heavy crude oil requires more complicated processing than lighter crude if it is to produce high-value products.

Overall, Canadian crude oil imports to U.S. refineries for processing have risen from over 1.3 million barrels per day in 2000 to just under 3.8 million barrels per day in 2022, an increase of 181 per cent (see Figure 1). The per cent of Canadian crude in U.S. refinery feedstock has steadily risen from nearly 9 per cent in 2000 to over 23 per cent by the end of 2022.

The U.S. refining industry

Since the first U.S. refinery began operating in 1861, the refining industry has been one of the largest manufacturing sectors in the United States. There are currently 129 petroleum refineries across the five U.S. PADDS³ (125 operating refineries and five refineries that are idle but not permanently shut down) (see Table 1).

Districts (PADDs) for the allocation of fuels derived from petroleum products, 
including gasoline and diesel fuel. The geographic breakdown of PADDs enables 
U.S. policymakers to better analyze petroleum supplies in the country

Total refining capacity in the United States has risen from 16.2 million barrels of crude processed in 2000 to nearly 17.8 million barrels per day in 2022, an increase of over 8 per cent (see Figure 2). The refining utilization⁴ has also recovered, growing from 79 per cent during COVID-19 to a high of 91 per cent in 2022.

The impact of the U.S. refining industry on the American economy

The estimated direct and indirect economic impacts of the U.S. refining industry in 2024 include 1.6 million direct and indirect jobs, $206 billion in labour income, $577 billion in direct and indirect value-added, and $1.6 trillion in what is known as “outputs,” i.e., the value of goods and services produced by the industry (see Table 2).⁵

Projected spending by the U.S. refining industry, 2024-2030

Figure 3 illustrates the industry’s projected annual spending between 2024 and 2030. Industry spending is expected to be US$58 billion in 2024, rising to US$62 billion by 2030. This includes operating expenditures (OPEX) and capital expenditures (CAPEX). Cumulatively, between 2024 and 2030, the industry is projected to spend over US$428 billion.⁶

Conclusion

American refineries are critical to the country’s strategic interest. U.S. refineries are projected to spend more than $428 billion in the next seven years on operating and capital expenditures. The industries support millions of jobs. Canadian crude is an important part of the equation. It supplies more than 23 per cent of U.S. refinery feedstock.

Not only are Canadian crude oil supplies critical for the U.S. refining industry, but they are key to North American energy security. Limiting access to Canadian crude oil for U.S. refineries would require increased U.S. imports from less-free countries, which in turn would risk North American energy security.

‘Churchill presents huge opportunities when it comes to mining, agriculture and energy’

When flooding in northern Manitoba washed out the rail line connecting the Town of Churchill to the rest of the country in May 2017, it cast serious questions about the future of the community of 900 people on the shores of Hudson Bay.

Eight years later, the provincial and federal governments have invested in Churchill as a crucial nation-building corridor opportunity to get resources from the Prairies to markets in Europe, Africa and South America.

The Port of Churchill is unique in North America.

Built in the 1920s for summer shipments of grain, it’s the continent’s only deepwater seaport with direct access to the Arctic Ocean and a direct link to the continental rail network, through the Hudson Bay Railway.

The port has four berths and is capable of handling large vessels. Having spent the past seven years upgrading both the rail line and the port, its owners are ready to expand shipping.

“After investing a lot to improve infrastructure that was neglected for decades, we see the possibilities and opportunities for commodities to come through Churchill whether that is critical minerals, grain, potash or energy,” said Chris Avery, CEO of the Arctic Gateway Group (AGG), a partnership of 29 First Nations and 12 remote northern Manitoba communities that owns the port and rail line.

“We are pleased to be in the conversation for these nation-building projects.”

In May, Canada’s Western premiers called for the Prime Minister’s full support for the development of an economic corridor connecting ports on the northwest coast and Hudson’s Bay, ultimately reaching Grays Bay, Nunavut.

AGG, which purchased the rail line and port from an American company in 2017, is not alone in the bullish view of Churchill’s future.

In February, Manitoba Premier Wab Kinew announced an investment of $36.4 million over two years in infrastructure projects at the port aimed at growing international trade.

“Churchill presents huge opportunities when it comes to mining, agriculture and energy,” Kinew said in a release.

“These new investments will build up Manitoba’s economic strength and open our province to new trading opportunities.”

In March, the federal government committed $175 million over five years to the project including $125 million to support the rail line and $50 million to develop the port.

“It’s important to point out that investing in Churchill was something that both the Liberal and Conservative parties agreed on during the federal election campaign,” said Avery, a British Columbian who worked in the airline industry for more than two decades before joining AGG.

The federal financial support helped AGG upgrade the rail line, repairing the 20 different locations where it was washed out by flooding in 2017.

Improvements included laying more than 1,600 rail cars worth of ballast rock for stabilization and drainage, installing almost 120,000 new railway ties and undertaking major bridge crossing rehabilitations and switch upgrades.

The result has seen travel time by rail reduced by three hours — or about 10 per cent — between The Pas and Churchill.

AGG also built a dedicated storage facility for critical minerals and other commodities at the port, the first new building in several decades.

Those improvements led to a milestone in August 2024, when a shipment of zinc concentrate was shipped from the port to Belgium. It was the first critical minerals shipment from Churchill in more than two decades.

The zinc concentrate was mined at Snow Lake, Manitoba, loaded on rail cars at The Pas and moved to Churchill. It’s a scenario Avery hopes to see repeated with other commodities from the Prairies.

Addressing Arctic challenges

The emergence of new technologies has helped AGG work around the challenges of melting permafrost under the rail line and ice in Hudson Bay, he said.

Real-time ground-penetrating radar and LiDAR data from sensors attached to locomotives can identify potential problems, while regular drone flights scan the track, artificial intelligence mines the data for issues, and GPS provides exact locations for maintenance.

The group has worked with permafrost researchers from the University of Calgary, Université Laval and Royal Military College to better manage the challenge. “Some of these technologies, such as artificial intelligence and LiDAR, weren’t readily available five years ago, let alone two decades,” Avery said.

On the open water, AGG is working with researchers from the University of Manitoba to study sea ice and the change in sea lanes.

“Icebreakers would be a game-changer for our shipping operations and would allow year-round shipping in the short-term,” he said.

“Without icebreakers, the shipping season is currently about four and a half months of the year, from April to early November, but that is going to continue to increase in the coming decades.”

Interest from potential shippers, including energy producers, has grown since last year’s election in the United States, Avery said.

“We’re going to continue to work closely with all levels of government to get Canada’s products to markets around the world. That’s building our nation. That’s why we are excited for the future.”

Temporary Alberta grid limit unlikely to dampen data centre investment, analyst says

Published on July 14, 2025

‘Alberta has never seen this level and volume of load connection requests’

Billions of investment in new data centres is still expected in Alberta despite the province’s electric system operator placing a temporary limit on new large-load grid connections, said Carson Kearl, lead data centre analyst for Enverus Intelligence Research.

Kearl cited NVIDIA CEO Jensen Huang’s estimate from earlier this year that building a one-gigawatt data centre costs between US$60 billion and US$80 billion.

That implies the Alberta Electric System Operator (AESO)’s 1.2 gigawatt temporary limit would still allow for up to C$130 billion of investment.

“It’s got the potential to be extremely impactful to the Alberta power sector and economy,” Kearl said.

Importantly, data centre operators can potentially get around the temporary limit by ‘bringing their own power’ rather than drawing electricity from the existing grid.

In Alberta’s deregulated electricity market – the only one in Canada – large energy consumers like data centres can build the power supply they need by entering project agreements directly with electricity producers.

According to the AESO, there are 30 proposed data centre projects across the province.

The total requested power load for these projects is more than 16 gigawatts, roughly four gigawatts more than Alberta’s demand record in January 2024 during a severe cold snap.

For comparison, Edmonton’s load is around 1.4 gigawatts, the AESO said.

“Alberta has never seen this level and volume of load connection requests,” CEO Aaron Engen said in a statement.

“Because connecting all large loads seeking access would impair grid reliability, we established a limit that preserves system integrity while enabling timely data centre development in Alberta.”

As data centre projects come to the province, so do jobs and other economic benefits.

“You have all of the construction staff associated; electricians, engineers, plumbers, and HVAC people for all the cooling tech that are continuously working on a multi-year time horizon. In the construction phase there’s a lot of spend, and that is just generally good for the ecosystem,” said Kearl.

Investment in local power infrastructure also has long-term job implications for maintenance and upgrades, he said.

“Alberta is a really exciting place when it comes to building data centers,” said Beacon AI CEO Josh Schertzer on a recent ARC Energy Ideas podcast.

“It has really great access to natural gas, it does have some excess grid capacity that can be used in the short term, it’s got a great workforce, and it’s very business-friendly.”
