Bailey's time of 9.84 in Atlanta was the 100m world record from 1996 until 1999, when it was broken by Greene. The time also stood as the Commonwealth record from 1996 until 2005, when it was broken by Asafa Powell, and is the current Canadian record (shared with Bruny Surin since 1999). It remains the Olympic record as of 2007.
