 DOSCO announced that its mines had 15 years of production left and that its steel mill was uneconomic to operate without significant modernization.In 1965–1966, a federal Royal Commission of Inquiry called the "Donald Commission" recommended that the federal government create a Crown corporation to take over operation of DOSCO mines with the aim being to gradually wean the industrial area economy off natural resources and into a more diversified service-oriented economy.On July 7, 1967 the Cape Breton Development Corporation (DEVCO) was created and on March 30, 1968 all DOSCO mines were expropriated for $12 million by DEVCO.
