The electoral district of Preston was created in 1992 following the recommendations of the Electoral Boundaries Commission report in order "to promote more effective representation for the Black community in the Legislature." The boundaries were drawn to encompass the Cherry Brook/Lake Major area, a part of the former Cole Harbour district, as well as the Preston/Lake Echo/Porters Lake area, formerly part of the Halifax Eastern Shore district. This district has the distinction of being the first to elect a Black representative -- Wayne Adams -- and the first Black female representative -- Yvonne Atwell. In 2013, following the recommendation of the Electoral Boundaries Commission, this district expanded southwest to include part of the Westphal area from Cole Harbour and the Ross Road area from Eastern Shore. It also expanded westward to gain the area north of Main Street and east of Caledonia Road until Geovex Court from Dartmouth East. SNS 2012 ch. 61 renamed this district Preston-Dartmouth.
