John McMartin

John McMartin (September 2, 1858 – April 12, 1918) was a businessman, mining executive and political figure in Ontario, Canada. He represented Glengarry and Stormont in the House of Commons of Canada from 1917 until his death in 1918, as a Unionist Party member.

Early life McMartin was born at Apple Hill, then part of Charlottenburgh Township, Canada West, and now part of North Glengarry, Ontario, to Allan McMartin and Mary Catherine McDougald (later styled McDonald) (1869 - 1941), daughter of John Angus McDougald (1838–1923), who was Local Registrar of the High Court of Justice, and a son of Major Angus McDougald, a member of the 4th Battalion Glengarry militia on active service during the Rebellions of 1837–1838, and his wife, Annie Chisholm (1843–1917), whose parents were Ranald Chisholm and Catherine McPhee. He was educated in Glengarry area public schools.

In 1909, the foursome purchased another claim from Benny Hollinger, incorporating Hollinger Mines in 1910, with the addition of a fifth partner, Timmins' ally, the Mattawa, Ontario, lawyer David A. Dunlap, for whom the David Dunlap Observatory is named, after he had shown great value to the enterprise by successfully defending their claim in court.

In 1903, McMartin established himself in Cornwall, Ontario,
