The CBSA has made changes to the way transactions are offset on a client account by changing the prioritization in the offsetting rules. Those changes are effective starting with the offsetting of the October 25, 2018 Statement of Account transactions.
More information on the updated client account offsetting Rules is available here: Fact Sheet on Importer Account Off-Setting
