Copps resigned briefly in the spring of 1996. One of Chrétien's campaign promises had been to abolish Brian Mulroney's highly unpopular Goods and Services Tax, a promise he later reneged on in an effort to avoid decreasing government revenues. During the 1993 election campaign, Copps promised during a Canadian Broadcasting Corporation "town hall" program that she would resign if the GST was not abolished. Copps, after some pressure, vacated her Hamilton East seat in 1996, and promptly ran again in the ensuing by-election.
