Haldimand—Norfolk has existed as a federal electoral district twice. It was first created in 1976 from the riding of Norfolk—Haldimand. Haldimand—Norfolk was later abolished in 1996, and was mostly replaced by Haldimand—Norfolk—Brant. It was recreated in 2003 from 12.0% of Erie—Lincoln and 88.0% of Haldimand—Norfolk—Brant.

From its first election in 1979 to 1988, Haldimand—Norfolk was represented by the Progressive Conservative Bud Bradley. In 1988, Liberal Bob Speller defeated Bradley. Speller went on to serve as Minister of Agriculture. In 2004, Haldimand—Norfolk elected Conservative candidate Diane Finley, who was re-elected in 2008 and 2011. After being re-elected in the 2006 election, Finley was appointed to the cabinet as Minister of Human Resources and Skills Development. She was shuffled from the Human Resources and Skills Development Canada to the Citizenship and Immigration Canada portfolio on January 4, 2007. After her 2008 election victory she resumed her former post as Minister of Human Resources and Skills Development in the Conservative minority government, a post she continued to hold until 2013.

This riding was left unchanged after the 2012 electoral redistribution.
