The FAQ in the "Guide to the use of the wind load provisions of ASCE 7-12" (don't have the -05 one yet) recommends using roof overhang coefficients for balconies, which are essentially the same as canopies.
ASCE 7-05 appears to have added Figures 6-18(MWF) and 6-19(C&C) for "Free Roofs". Is a canopy (or a balcony) a free roof with "Obstructed Wind Flow"?
