The Irving Group of Companies is an informal name given to those companies owned and controlled by the descendants of Canadian industrialist K.C. Irving, namely his children J.K. (b. 1928), Arthur (b. 1930), and Jack (1932–2010) and their respective children. Ownership structure Many of the components of the Irving Group of Companies were established or acquired by K.C. Irving during his period of active entrepreneurship between the 1920s and the 1970s. Following his retirement to Bermuda in the 1970s, the conglomerate was operated by his three sons in much the same manner and remained relatively intact and maintained a strong vertical integration. The companies were divided into similar divisions, each controlled by one of K.C. Irving's sons and their respective children. James K.
