At the CIAU Nationals, she qualified for All-Canadian status four times and won 11 medals, including three golds, five silvers and three bronzes. Chiang's first CIAU gold was in the 50m freestyle during her sophomore year. Her other gold medals occurred at the 1997 meet, as part of the 4x100 freestyle (4:15.83) and the 4x200 free (8:20.02), which established a CIAU record time.
In 1996, she finished fifth in the 50m free at the Canadian Olympic trials, missing the cut by one-tenth of a second.
