Calgary, Oct. 09, 2003 (TSX – COS.UN) —Canadian Oil Sands Trust (“Canadian Oil Sands” or the “Trust”) announced today that Coker 8-1, a primary upgrading unit at Syncrude’s oil sands facility, was taken down for unscheduled maintenance earlier today.

The Trust will provide additional information, such as the impact on unit operating costs, once an analysis of the unscheduled maintenance is completed.
