The document discusses Canada Border Services Agency's (CBSA) Advance Commercial Information (ACI) and Customs Self-Assessment (CSA) programs. CSA provides streamlined customs clearance for pre-approved importers while ACI is the baseline program requiring advance electronic import data. CSA offers benefits like faster clearance, accounting and payment through an electronic system. The Free and Secure Trade (FAST) program provides further expedited clearance by building on CSA and security measures of the Partners in Protection program. Participation in CSA and FAST is growing and seen as the future direction.
