Educated at the Codys public school and at the Baptist Seminary in Fredericton, N. B., he studied medicine at the Chicago Homeopathic Hospital, Chicago, Illinois, and at Rush Medical School, Chicago, Illinois.

He practiced his profession in Chicago for a short while and then returned to Codys to practice medicine. He was President of Hetherington Brothers Mercantile, Lumbering and Milling Company, a member of the Union Club and Elks Club, the Canadian Club of Boston and a member of A.F. & A.M.

He was first elected to the House of Assembly of New Brunswick as a member for Queens County at the general election of February 24, 1917. He was elected at the general election of October 9, 1920 and at a by-election held December 27, 1920, which was made necessary by his acceptance of office. At the general election of August 10, 1925 he was defeated and retired from politics.

The Daily Gleaner of January 30, 1928 describes Dr. Hetherington:

Dr. Hetherington had ably sustained the important duties of administering the provincial finances for several years and later filled the office of Speaker with dignity and wise judgment. He had attained much success in the medical profession in Chicago when he returned some years ago to his native province and his home county of Queens.
