Massachusetts born, Hiram Walker had by the 1850s become a successful general merchant, distiller and grain dealer in Detroit. After Michigan adopted prohibition in 1855 he acquired land across the river in Canada where he established a distillery and mill which became the nucleus of the company town of Walkerville. Soon the Walker enterprises had expanded to include cattle finishing (using distillery wastes), a river ferry, and a railway to transport the company's products. Although Walker himself lived in Canada only from 1859 to 1864, he played an important role in the economic development of western Ontario.
