The Canol Project was an oil pipeline project constructed during World War II to ensure a supply of oil for the defense of Alaska and the North American west coast. The project included a section of crude petroleum transport by barge, a refinery, and a 4-inch pipeline. It was completed in two years at great cost and was abandoned less than a year later.
During World War II the United States was concerned about Japan attacking the west coast and cutting off supply lines to Alaska. They built the Alaska Highway to connect Alaska to the rest of the United States and conceived the CANOL (Canadian Oil) project to ensure a supply of oil from Norman Wells in the Canadian Northwest Territories. The US War Department decided to construct the project in April 1942 and it was assigned to the United States Army Corps of Engineers.[1]
The construction of infrastructure to Alaska via Norman Wells was first raised by the arctic explorer Vilhjalmur Stefansson, who proposed a water connection from the railhead at Waterways, Alberta to Norman Wells, and then a road to Fairbanks via Dawson City as an alternative to the Alaska Highway.[2]
Oil in the Norman Wells area was noted as far back at 1789 when the explorer Alexander Mackenzie noted seepage of oil along the river that would later bear his name.[3] Claims for oil were staked by the geologist T.O. Bosworth, and they were subsequently acquired by Imperial Oil, which drilled three producing wells and built a small refinery by 1924. Local demand was so small that refinery soon closed, but it re-opened in the early 1930s to supply the Eldorado Mine at Port Radium.[4]
The order to construct a pipeline from Norman Wells to Whitehorse was issued by Brigadier General Brehon B. Somervell, head of the Construction Division of the Quartermaster Corps, based on the recommendation of Colonel James Graham, the Dean of Engineering at the University of Kentucky. Graham based his recommendation on a one-day conference he organized, attended mostly by Army officials, where no one present was familiar with the area the pipeline was to be built.[2]
W.A. Bechtel Co, H. Price & Co. and W. E. Callahan Construction Co. formed a consortium to construct the project. Known as Bechtel-Price-Callahan (BPC) it also included six associated companies. Standard Oil Company was a consultant on the project and would operate the refinery in Whitehorse. Imperial Oil owned the Norman Wells field and would be responsible for the supply of oil. J. Gordon Turnbull and Sverdrup and Parcel were chosen to the project's architect and engineer of record.[1]
A total of 1,600 miles (2,600km) of pipelines connecting Whitehorse to:
Norman Wells (Canol No. 1)
Skagway (Canol No.2)
Watson Lake (Canol No.3), and
Fairbanks (Canol No. 4)
A telegraph system connecting all key points of the project
Survey
In 1942, Europeans had limited knowledge of the area between Norman Wells and Whitehorse, as the Mountain Dene or Shutagot'ine would come down from the mountains to trade with European traders along the Mackenzie River.[5] BPC hired a land surveyor named Guy Blanchet to identify a route. Interviews with Dene from Fort Norman (now Tulita) identified a trail through the Mackenzie Mountains that was the most suitable, and in October 1942 Blanchet, four guides from Fort Norman (Fred Andrew, Little Edward Blondin, George Blondin, and Paul Wright)[6][7][5] and two others set out by dog sled to survey the route that would eventually become the crossing of the pipeline over the Mackenzie Mountains. (though construction on the road had already begun by then) Subsequent surveys along this route by teams using heavy equipment were abandoned as the extreme cold caused machinery to fail. While there were several aerial photo projects, they were inconsistent and it is not clear how much they were used to guide location. Typically, much of the route decisions were made during construction, resulting in numerous "false starts" and reroutes of the road.[8]
Logistics
Much of the pipeline and equipment for the eastern section of Canol No.1 was moved by rail to Waterways, Alberta (today a suburb of Fort McMurray), where it was transferred to barges to take it up the Athabasca River. The Army was initially unaware that the unnavigable Slave Rapids made navigation to Great Slave Lake impossible, and barges had to be portaged by truck from Fort Fitzgerald to Fort Smith. Once the Mackenzie River froze over, the army constructed an ice road to Norman Wells.[9]
The work of loading barges cutting wood to supply the boilers of paddle boats was assigned to the 388th Engineer Battalion (Separate), a segregated unit of 1,000 black men with white officers from Camp Claiborne, Louisiana. The men of the 388th were given the most demanding work, and were the lowest priority for rations, equipment, and accommodations, with some of them spending the harsh sub-arctic winter in tents.[5][9]
The western portion of the Canol was comparatively easy to supply, as supplies could be shipped to the port Skagway and then transported to Whitehorse on the White Pass Railroad.[9]
Building the pipeline
The pipeline itself was built by the civilian BPC consortium, which hired 52,900 people, mostly men who were ineligible for military service. While the contractors were permitted to hire Canadian workers, the Canadian government did not want the Canada's wartime industries to lose workers to what was seen as a U.S. project, and Canadians made up less then 20% of the workers on the project. While BPC emphasized the challenging conditions in its hiring, with posters warning prospective workers that they "will be required to work and live under the most extreme conditions imaginable," the project experience high rates of turnover, with 28,000 workers not finishing their 9-month contracts.[9]
The pipeline was just 4 inches (10cm) in diameter. The low gravity crude oil from Norman Wells had a pour point well below the freezing mark and could be run through a narrow pipeline without being heated.[9] The pipeline was laid on the surface of the ground to simplify construction and maintenance.[1] Ten pump stations were needed to move the crude oil to Whitehorse. The pumps were specially designed to be able to use the Norman Wells crude as fuel. An additional 19 pump stations moved the refined fuel along the Alaska Highway from Whitehorse as far as Watson Lake and Fairbanks.[9]
The Whitehorse refinery was purchased used and shipped up from Corpus Christi, Texas.[10] It was operated by Standard Oil and located in the Maxwell Industrial Area north of present-day Downtown Whitehorse.[11]
The final construction cost for the Canol Project construction has been estimated at US$133 million (equivalent to $2,375,646,503in 2024) and may have been closer to $300 million when military personnel are included.[9][12]
Operation
The last pipeline weld was completed on February 16, 1944, near Macmillan Pass. Oil first entered the pipeline at Norman Wells on 19 December 1943, but due to construction issues oil did not reach the Whitehorse refinery until 1 April 1945.[13] The grand opening was held on April 30.[9] Initially only able to produce gasoline, it was finally able to produce aviation gas in November 1944.[11]
Over the life of the Canol No.1 pipeline 1,161,394 US barrels (138,485,200L) were pumped into the line at Norman Wells. Only 83.7% of that arrived in Whitehorse. Most of the remaining 189,709 US barrels (22,621,000L) is believed to have been lost due to pipeline breaks.[14] The pipeline had been fully operational for 331 days when it was shut down on 13 March 1945.[15]
Camps and pump stations
The Canol System had a network of manned pump stations, maintenance camps,
Due to its remoteness and challenging conditions the costs to provide fuel from the Canol were considerably higher than having fuel arrive via tanker. On March 8, 1945, the US War Department made the decision to shut the project down. Work began immediately to winterize all equipment, clean and stock camps and remove all personnel.[38]
The Canadian government had right of first refusal to purchase the pipeline, but prior to shutdown had already concluded that the cost of operating the project was far greater than shipping in oil.[39] The U.S. Army hoped to find a private-sector buyer for the entire project, but was unsuccessful. Instead the project was sold off in pieces while Canol No. 1 was sold for scrap and abandoned.[40]
Imperial Oil purchased equipment at Norman Wells for $3 million.[41] Imperial also paid $1 million for the Whitehorse refinery, which had been installed at a cost of $27 million, which they then dismantled and shipped to Alberta. The salvage rights for the remainder of the line were sold for $700,000 and carried out by George Price of Dawson Creek, British Columbia.[9] Some valuable equipment was salvaged but much of the pipeline, telegraph wire, vehicles and buildings were left in place.
The Skagway-Whitehorse (Canol No.2) and Whitehorse-Fairbanks (Canol No.4) sections remained in use for fuel delivery from tankers at the Port of Skagway to Whitehorse and Fairbanks until 1958, when it was replaced by the larger Haines-Fairbanks Pipeline.[42] It was then sold to the White Pass & Yukon Company (WPY).[43] WPY dismantled the Canol No.4 by 1962, but continued to operate Canol No.2 until 1994, when the pipeline was removed.[43][44]
The Canol Road is still seasonally maintained within the Yukon and is known as Highway 6. A ferry in the community of Ross River, Yukon is used to cross the Pelly River. There are several old vehicle dumps remaining on the Yukon side and an old pipeline crossing remains in Ross River. The bridge has been used as a footbridge and was recently refurbished.[45]
In the Northwest Territories the road is no longer maintained and is now the Canol Heritage Trail. It is estimated that 46,000 barrels of crude oil were spilled along the pipeline route.[9] Many of the abandoned buildings and vehicles contain hazardous materials and telegraph wire has entangled animals such as moose and caribou.[46] Clean-up of telegraph wire began in 2015 and most of the wire along the trail has been coiled up for removal.[47][48] Remediation work began in 2018 to remove contaminants, telegraph wire and other safety hazards along the trail and expected to be completed in 2020.[49] Remediation of the trail will allow the creation of Doi T'oh territorial park to proceed as set out in the Sahtu Dene and Metis Comprehensive Land Claim Agreement.[50]
Cleanup began in 2018 at the former site of the refinery in Whitehorse, known locally as the Marwell tar pit. Work was expected to be completed in 2020 at a cost of almost $7 million.[51]
Imperial Oil's Norman Wells operations continued after the closure of the Canol pipeline, supplying local demand up and down the Mackenzie River with barges. Additional wells and a new processing facility were opened in 1985, alongside Enbridge's Line 21 pipeline, which links Norman Well to the broader Canadian pipeline network at Zama City, Alberta along a much simpler southeastern route that follows the Mackenzie River.[52] As of 2025, closure and remediation of the wells and associated production infrastructure is anticipated for the late 2020s or early 2030s.[53]
