Guy St. Just was a Liberal member of the Grand Council from the Northern Confederation in the 1900s. At the Liberals' national convention in January 1908, St. Just was chosen as the party leader and the Liberals' nominee for Governor-General in the 1908 Grand Council elections.
St. Just faced Councilman Albert Merriman of Indiana, who had been nominated by the People's Coalition at their national convention that same month. Merriman was the hand-picked successor of incumbent Governor-General Christopher Hemingway, who had chosen to retire from the office and resume his Council seat. Hemingway was the most popular figure in the Confederation of North America at the time, and on election day in February the Liberals saw their share of seats in the Grand Council fall from 67 to 60. Sobel makes no further mention of St. Just after the 1908 elections.
Guy St. Just has no entry in Sobel's index.
