Ontario Malleable Iron Company (OMIC) was an iron foundry established in Oshawa, Ontario, by brothers John Cowan and William Cowan. The factory was in operation from 1872 until closure in 1977. Ontario Malleable, along with many other industrial firms in Oshawa, enabled comparisons between Oshawa and Manchester, England, such that Oshawa was, in the 1920s, referred to as the "Manchester of Canada".
