The 2010 Alberta electoral district boundary re-distribution significantly changed the riding. The western boundaries were altered to conform to the new Calgary city limits which had been expanded since 2003. The riding lost all land that was east of Sarcee Trail and North of the Bow River to the electoral districts of Calgary-Currie and Calgary-Varsity. The district was also expanded south into land that used to be in Calgary-West up to the new south boundary of Bow Trail / 12 Street SW. The Calgary-Bow electoral district would have a population of 37,806, which was 7.5% below the provincial average of 40,880.
