In January 2008, Oliphant sought the federal Liberal nomination of Don Valley West after John Godfrey announced his retirement. Others interested in the nomination included former Liberal MP Sarmite Bulte, prominent constitutional expert Deborah Coyne, local imam Abdul Ingar, and Jonathan Mousley. During the nomination process, Coyne accused Oliphant and Bulte supporters of signing up members who hadn't paid a membership fee, a violation of party rules. Members of the press contacted several people who had signed up as members who confirmed they had not paid a fee. Oliphant replied that he had instructed his campaign team to follow the rules.
