He initiated the final agreement for a transpacific cable linking Canada to Australia and New Zealand, and funded Marconi to establish the first transatlantic radio link from North America to Europe. In 1905 he chaired the parliamentary inquiry into telephones that led to regulation of Canadian telecommunications, and he participated in the negotiations that led to the creation of the provinces of Alberta and Saskatchewan. He was Chief Justice of the Exchequer Division of the Supreme Court of Ontario from 1905 until appointed by King in 1923 as Chief Justice of the Supreme Court of Ontario, a position he held until 1936.

Mulock was extremely active in both business and the community, being involved in the foundation of organizations as diverse as the Toronto-Dominion Bank, the Toronto Star, Toronto Wellesley Hospital, and Canada's first national peace organization. In later life he was known as the "Grand Old Man" of Canada.
