Incorporated in 1928 and operational by 1930, DOSCO was predated by the British Empire Steel Corporation (BESCO), which was a merger of the Dominion Coal Company, the Dominion Iron and Steel Company and the Nova Scotia Steel Company. DOSCO was one of the largest private employers in Canada during the 1930s–1950s. In 1957, DOSCO was purchased as a subsidiary of A.V. Roe Canada Ltd. In 1966 it terminated coal operations.

Industrial Cape Breton consisted of two distinctive geographic regions for industrial activity: the "north side" of Sydney Harbour, and the "south side". The north side was dominated in the 1800s by the General Mining Association (GMA), which had been formed in the 1820s after the Colony of

. By 1912, DOMCO operated 16 collieries, comprising 40% of Canada's coal production. The company effected numerous efficiencies and improvements. There were, however, costly mistakes, prominent among them the tendency to become locked into low-price contracts (such as to Whitney's companies), thus missing a large market at higher prices. By 1901 some 90 percent of its output was committed to such low-price contracts. The company made a large public offering of stock, which tumbled in price when Whitney failed to get the American import duty on coal removed or at least reduced.


Dominion Iron and Steel Company

Flushed with the success of creating DOMCO in the 1890s, the Whitney syndicate sought to create a use for "slack coal" resulting from mixing and screening processes at DOMCO's coal wash plants. Whitney expanded operations at Sydney with the organization in March 1899 of the Dominion Iron & Steel Company Ltd. (DISCO), which had funding in both Canada and the United States. Whitney was joined in the new enterprise by his long-time business friends F.S. Pearson, B.F. Pearson, W.C. Whitney, C.T. Barney, H.F. Dimock, A.H. Paget and J.S. McLennan.

, and shipped to Sydney. Competitors in Britain, France, Germany and the United States were initially concerned. However, continuing problems of management and cost control led to Whitney's early withdrawal from the project. Later in 1901, Whitney and his associates sold majority control of DOMCO to engineer turned businessman James Ross of Montreal, and their minority share of DISCO to Ross and other Canadian interests. Whitney resigned as president of DISCO in 1902 and as a member of the DOMCO board in December 1909; he remained a member of the DISCO board until 1909. The year 1901 also saw further changes in the coal and steel industry on Cape Breton Island when the rival GMA, operator of coal mines on the "north side" of Sydney Harbour, as well as a newly inaugurated steel mill at that location, sold its properties to Nova Scotia Steel Company Ltd.

industrialist Roy M. Wolvin negotiate a takeover of Dominion Steel Corporation from Plummer in 1919. BESCO proposed a $500 million merger of DOMCO and DISCO, along with various British steel and shipbuilding interests. In 1921, SCOTIA was merged with the conglomerate to form the British Empire Steel Corporation (BESCO). The scope and scale of BESCO was truly mind-boggling. In addition to its coal mines and steel mills operating as a complete monopoly across the entire Sydney Coal Field, BESCO also operated coal mines, steel mills and foundries in the Pictou Coal Field in Trenton, New Glasgow, Stellarton and Westville, as well as North America's deepest coal mines in

, and iron mines in Bell Island, Newfoundland. It also operated several industrial railways and various shipping ports throughout the province. However, the mergers that resulted in the formation of BESCO also amalgamated an inordinate amount of debt. During its 8-year history, BESCO was in a constant financial crisis and by 1925 required an annual operating profit of $8 million ($100 million when adjusted for inflation in 2010) to meet these financial commitments. As a result, BESCO's investors pressured management to force many difficult working conditions in order to achieve higher production from its workforce. This resulted in unprecedented labour unrest and militancy which would forever transform Industrial Cape Breton (see Davis Day). Profits fell and coal and steel markets were declining throughout the 1920s as North America's industrial and consumer practices changed. BESCO management tried to desperately save the company, however bitter strikes by workers, culminating in widespread social and civil unrest in 1925, saw BESCO slip further into debt. BESCO subsidiary DISCO (the steel mill) fell into receivership in the spring of 1926 after short-term financing was refused; this would eventually lead to the break-up of the conglomerate. DISCO was liquidated in 1927 but the

refused to dissolve BESCO. Wolvin resigned as president and sold his holdings after his reorganization plan was rejected by other shareholders and he was succeeded by C.B. McNaught.


Creation of DOSCO

In 1928 a new holding company called Dominion Steel and Coal Corporation (also DOSCO) was formed as a holding company by McNaught and various BESCO investors. In May 1930 BESCO was dissolved and the new company took over its industrial properties. DOSCO implemented management processes that put a halt to the financial troubles through the 1930s. The company's fortunes were boosted by

By the early 1960s DOSCO was in a continuous slide and sought to halt its decline by shutting various poorly performing mines in the Pictou and Sydney coal fields; from 9 in 1960 to 5 in 1965. Despite shedding other money-losing subsidiaries it was still losing money and under pressure from Hawker Siddeley Canada to reduce red ink.
