In 1872, Mowat became Ontario's third prime minister and retained that post for almost 24 years. Resigning in 1894, he accepted a seat in the Senate, and became minister of Justice 1896-97 in the cabinet of Sir Wilfred Laurier. Mowat served as lieutenant-governor of Ontario from 1897 until his death.
A man who took pride in being regarded as a Christian statesman, Mowat's success in public life was widely attributed to a popularity and prestige gained through his tact and integrity.
Canada Post Office honoured Sir Oliver Mowat by issuing a stamp commemorating the 150th anniversary of his birth on August 12, 1970.
