FAST
The Free and Secure Trade (FAST) program is a joint United States-Canadian program between the Canada Border Services Agency and the U.S. Customs and Border Protection. The FAST initiative offers pre-authorized importers, carriers and drivers expedited clearance for eligible goods, building on what Canada previously implemented under their Customs Self Assessment (CSA) program.
