Speller was born in Hagersville, Ontario and, in 1983, married Joan Mouland, with whom he has a son, Christopher, and a daughter, Victoria.
Speller was first elected in the 1988 Canadian federal election as a member of the Liberal Party, defeating incumbent Bud Bradley by only 209 votes. Brian Mulroney's Progressive Conservatives won the election, however, relegating Speller to opposition Member of Parliament (MP). As an opposition MP, Speller was Associate Trade Critic, Youth Critic and Chair of the Liberal Rural Caucus.
Speller was re-elected in 1993, 1997 and 2000, as a member of the winning party. Jean Chrétien's Liberals won three successive elections. Speller served on the House of Commons Standing Committee on Agriculture and Agri-Food (1994–1995), served on the Canadian Parliamentary Association International Executive Committee, served on the Parliamentary Steel Caucus (1993, 1994, 1998), served on the Joint Inter-Parliamentary Council, and was Chair of the Sub-committee on Trade, Trade Disputes and Investment and the Commonwealth Parliamentary Association (Canadian Branch).
Speller represented the constituency of Haldimand—Norfolk—Brant until riding lines were redrawn prior to the June 2004 federal election. In his new riding of Haldimand—Norfolk, Speller lost the election to Conservative candidate Diane Finley, and formally left cabinet the following July.
In June 2005, Prime Minister Paul Martin asked Speller to consider running in the next federal election. Speller ran in the following general election, but was defeated again. Speller did not run in the 2008 federal election but ran again in the 2011 federal election.
