John Arthur Fullerton (May 12, 1912 – July 5, 1965) was a politician in Ontario, Canada.
He was born in Thessalon, Ontario, the son of James Albert Fullerton, and educated there.
[2] In 1945, Fullerton ran as the Progressive Conservative candidate in the northern Ontario riding of Algoma—Manitoulin.
[8] Fullerton attributed his loss to "free beer and cocktail parties" given out by the opposition.
Others believed that the loss was due to a controversial relocation of a senior's residence that was to be built in Espanola but was instead moved to his own home town of Thessalon.
