Calgary Heritage was created by the 2012 federal electoral boundaries redistribution and was legally defined in the 2013 representation order.

It is essentially a reconfigured version of Calgary Southwest, the riding formerly represented by Stephen Harper, who served as the Prime Minister of Canada from 2006 to 2015.

Its predecessor, Calgary Southwest, frequently gave Conservative candidates some of the highest margins in the nation.

While Harper was handily re-elected to this riding in 2015, his Conservatives lost their bid for a fresh mandate to the Liberals.

[5] A by-election to fill the seat was held on April 3, 2017; Bob Benzen retained it for the Conservatives and was subsequently re-elected in the nationwide elections of 2019 and 2021.
