The original Calgary Centre was created in 1966 from parts of the former electoral districts of Calgary North and Calgary South. This riding was abolished in the 2003 Representation Order when parts of it went to the neighbouring electoral districts of Calgary North Centre and Calgary West and to Calgary South Centre. The latter was renamed Calgary Centre in 2004. When it was created in 2003 (as Calgary South Centre), it included 70,972 people from the abolished district of Calgary Centre, 38,889 people from Calgary West and 7,578 from Calgary Southwest.
