[2] Fox was first elected to the Manitoba legislature in the provincial election of 1966, defeating Progressive Conservative incumbent James Mills[1] by 836 votes in the east-end Winnipeg riding of Kildonan (he had previously defeated Russell Doern to win his party's nomination).
The NDP scored an upset victory in the provincial election of 1969, and Fox was easily returned in Kildonan.
He was re-elected without difficulty in the 1973 election,[1] but faced a surprisingly strong challenge from PC candidate James Hanson in 1977.
He does not appear to have been a strong supporter of Howard Pawley, Schreyer's successor, but unlike Green and some others did not leave the party during the 1980s.
In late 1986, he was appointed Vice-Chair of the Highways and Transportation Department Licence Suspension Board.
