This article is the Electoral history of Sir John Sparrow David Thompson, the fourth Prime Minister of Canada. A Conservative, he became prime minister upon the resignation of Prime Minister Sir John Abbott in 1892. Thompson served a short term of just over two years as prime minister (1892-1894), until he died suddenly in office and was succeeded by Sir Mackenzie Bowell. He never led his party in a general election. Before entering federal politics, Thompson was a member of the General Assembly of Nova Scotia from 1877 to 1882. He was the Attorney General for Nova Scotia from 1878 to 1882 and was briefly the Premier of Nova Scotia in the run-up to the general election of 1882. Summary Thompson ranks sixteenth out of twenty-three prime ministers for time in office, serving one short term of just over two years (1892-1894). He became prime minister upon the resignation of Sir John Abbott and was only in office for a total of 2 years and 7 days. Thompson was the first of three prime ministers from Nova Scotia, the others being Sir Charles Tupper and Sir Robert Laird Borden. Although he was the leader of the combined Liberal-Conservative Party and the Conservative Party, he did not lead the party in a general election. He died suddenly at Windsor Castle in England, shortly after being sworn a member of the Privy Council of the United Kingdom. Thompson entered federal politics as the urging of Prime Minister John A. Macdonald. He stood for election to the House of Commons of Canada three times, a by-election in 1885 and the general elections of 1887 and 1891, winning all three times. He represented the federal constituency of Antigonish, Nova Scotia. He served in the House of Commons for 9 years, 1 month and 28 days.

He was the Attorney General for Nova Scotia from 1878 to 1882 and was briefly the Premier of Nova Scotia in the run-up to the general election of 1882.
