(Bill Clarke of Vancouver Quadra was the other; he lost to Prime Minister John Turner, who needed a seat in the House.)
After failing to win a nomination as a Progressive Conservative candidate for the new riding of Markham, Gamble ran without affiliation in the 1988 election in that district.
On May 31, 1993, Gamble won the Reform Party's nomination in Don Valley West for the 1993 federal election, but was expelled by the party (Gamble was replaced by Julian Pope, who lost to John Godfrey) prior to the election because of his links to far-right extremists such as Paul Fromm, Ron Gostick, Wolfgang Droege, and the Heritage Front.
In the 1980s, Gamble was involved with the hard-right World Anti-Communist League as head of its affiliate the "Canadian Freedom Foundation".
According to a report by the Security Intelligence Review Committee, Paul Fromm assisted Gamble in this WACL work.
