Overview
Canadian Oil Companies, Limited was a historically important Canadian integrated petroleum company whose activities covered refining, petroleum distribution, oil exploration and production, gas processing, marine transportation, storage, and retail fuel marketing. Although the company formally existed from 1908 until 1963, its corporate roots reached back to a 1904 amalgamation of four Southwestern Ontario oil businesses. The resulting holding company was first called Canadian Consolidated Oil Company, Limited and soon changed its name to Canadian Oil Company, Limited. The business encountered financial difficulty and entered bankruptcy in 1908. The Cleveland-based National Refining Company acquired its assets for $400,000 and reorganized them into a new company, Canadian Oil Companies, Limited, incorporated on 4 December 1908. Under National Refining's ownership, the Canadian business adopted product names and promotional methods already used in the United States. Its principal consumer brands included White Rose gasoline, En-Ar-Co motor oil, and Black Beauty axle grease. White Rose became the company's most recognizable public identity and was sold through a large national network of filling stations. Canadian Oil Companies developed from an Ontario refining and marketing business into a vertically integrated petroleum enterprise. Its early refining base was the Petrolia Refinery, built in 1901 by one of the predecessor companies. The company closed that facility in 1952 and replaced it with a much larger refinery at Corunna, near Sarnia, Ontario. The new Sarnia refinery cost approximately $23 million and was opened on 25 September 1952. Canadian also expanded westward. In 1955 it acquired Anglo-Canadian Oil Company, gaining an established exploration and development operation in Western Canada. In 1961 it opened a combined refinery and gas-processing facility near Bowden, Alberta. The company's corporate ownership changed significantly before its final sale. In late 1938, Montreal investment firm Nesbitt, Thomson and Company purchased a controlling interest from National Refining; the transaction became effective in January 1939. The interest was later transferred to Power Corporation. By the early 1950s, approximately 99 percent of Canadian Oil's shares were domestically owned, making it one of the country's largest Canadian-controlled petroleum companies. Its national presence included refineries, storage infrastructure, tanker vessels, exploration and production assets, and about 3,000 White Rose service stations at the time of the Shell transaction. Canadian Oil Companies also had a visible architectural and advertising presence in Toronto. Its offices occupied the Terminal Building on the waterfront before the company purchased the Goodyear Building at 204 Richmond Street West in 1947. The latter was renamed the White Rose Building, and the company moved there in 1948. A further move to a purpose-built Canadian Oil Building at 188 University Avenue was announced in 1956. The company disappeared as an independent Canadian-controlled oil business after a contested 1962 takeover. Shell first offered $39 per share in July, but the board rejected that proposal. In September, Shell Investments offered $52.20 per share, while Hudson's Bay Oil and Gas proposed a share exchange. The board recommended the Shell offer, which was accepted by Power Corporation and ultimately approved by shareholders. The transaction covered the Sarnia and Bowden facilities, two tanker ships, approximately 150 storage tanks, and the White Rose retail network. The company's value was reported at approximately $125 million in contemporary accounts. The acquisition ended the history of what was described as Canada's last major domestically owned integrated petroleum company. Its facilities and brand legacy continued under Shell, although White Rose eventually became primarily a historical Canadian fuel brand.
History
Canadian Oil Companies grew out of the consolidation of four Southwestern Ontario oil businesses in March 1904: Canadian Consolidated Oil Company, Canadian Oil Refining Company, Sun Oil Refining Company of Hamilton, and Grant Hamilton Oil Company of Toronto. The holding company initially used the name Canadian Consolidated Oil Company and was headquartered in Toronto. It adopted the name Canadian Oil Company, Limited, on 4 April 1904, with William Irwin as its first president. The company failed financially by 1908. National Refining Company, a Cleveland petroleum business founded by Julius I. Lamprecht, purchased the Canadian assets for $400,000. National reorganized the operation and incorporated Canadian Oil Companies, Limited, on 4 December 1908. The new company retained and expanded the predecessor businesses' refining and distribution activities while introducing product names and advertising concepts associated with National Refining in the United States. White Rose gasoline became the central consumer brand. The name had originally been used by National Refining for stove gasoline and was extended to automotive gasoline in 1905. Canadian Oil Companies also sold En-Ar-Co motor oil and Black Beauty axle grease. Its promotional system included the Boy and Slate signs developed in the United States. In 1937 the company held a competition for a new White Rose logo; Bill Templeton's design won, and the older Boy and Slate imagery was retired in 1939. The company's original refining asset was the Petrolia Refinery, built in 1901 by the Canadian Oil Refining Company. Canadian Oil Companies operated it until closing the facility in 1952. It simultaneously built a new $23 million refinery at Corunna, south of Sarnia, Ontario. C. D. Howe opened the Sarnia-area facility on 25 September 1952. Canadian expanded its Western Canadian presence in 1955 by purchasing Anglo-Canadian Oil Company, obtaining a developed exploration and development department. On 20 June 1961 it opened a refinery and gas-processing plant near Bowden, Alberta, with the facility formally opened by Alberta premier Ernest Manning. Ownership shifted toward Canadian control in the late 1930s. Nesbitt, Thomson and Company bought National Refining's controlling interest in December 1938, with the transaction taking effect on 28 January 1939. The interest later moved to Power Corporation. By the early 1950s, about 99 percent of the company's shares were domestically owned. This made Canadian Oil Companies an important example of Canadian-controlled petroleum ownership during a period when foreign companies were acquiring several major domestic oil businesses. Canadian Oil operated marine assets as part of its supply system. Its first tanker, acquired in 1906 and later renamed En-Ar-Co, served the company until it was scrapped in 1934. A second vessel, acquired in 1945 and ultimately named White Rose, remained associated with the company after several renamings. Canadian also commissioned the W. Harold Rea, christened in August 1962. After the Shell acquisition it became Eastern Shell II. The company maintained prominent Toronto offices. It occupied the Terminal Building on the waterfront, where White Rose and En-Ar-Co signs were displayed, before purchasing the Goodyear Building at 204 Richmond Street West in 1947. The property was renamed the White Rose Building, and the company moved there in 1948. In 1956 it announced plans for a new nine-storey headquarters at 188 University Avenue. In July 1962 Shell, through Hesper Oil Company, offered $39 per share, but the board rejected the proposal. In September Shell Investments offered $52.20 per share, while Hudson's Bay Oil and Gas proposed a share-based alternative. The board recommended Shell's offer, which Power Corporation accepted on behalf of its controlling interest. The transaction covered the Sarnia and Bowden facilities, two tankers, around 150 storage tanks, and approximately 3,000 White Rose stations. The reported value was about $125 million. The proposed takeover prompted political discussion in the House of Commons because Canadian Oil was regarded as the last major domestically controlled integrated petroleum company. The sale ended the company's independent corporate existence by 1963. Its physical and cultural legacy persisted. Canadian Oil had acquired the Oil Springs site associated with James Miller Williams's 1858 commercial oil well and donated it in 1957 for the Oil Museum of Canada, which opened in 1960. Shell continued using the Sarnia refinery after the acquisition. The Bowden refinery closed in 2001, while its gas-processing operations continued. The White Rose name survived in Canadian memory and was later referenced in popular music, including Fred Eaglesmith's 1995 song "White Rose."
