Elliott's varied career in British Columbia included gold commissioner, stipendiary magistrate, and, following the union of the Island and Mainland Colonies in 1866, high sheriff of the province. He resigned his magistracy to take the post as High Sheriff. He was a member of the colony's appointed Colonial Assembly from 1865 to 1866. After the colony became a province of Canada, he was elected, in 1875, to the Victoria City seat in the provincial legislature and became leader of the opposition. Before his election to the House, he was a provincial magistrate in Lillooet.
In 1876, Elliott became the fourthPremier of the province on the defeat of George Anthony Walkem's government in a Motion of No Confidence. His government was unstable, and he was unable to make progress with the federal government on the province's demands that Ottawa builds a railway to the Pacific. Tax increases and the government's failure to secure a railway terminus for Victoria, British Columbia led to Elliott's defeat in his riding in the 1878 election as well as the defeat of his government.
He administered justice with a fearless hand and soon had discordant elements well in check. He was a genial, whole-souled gentleman of generous impulses and possessed the highest kind of honor. He was a brave man.
Family life
His daughter Mary married James W. Douglas, the only son of James Douglas, but his son-in-law died at age 32, and Elliott was one of the pallbearers at the funeral.
