This notice is available in its entirety on the Canada Border Services Agency website.
Effective on the day of coming into force of CUSMA, the CBSA will increase its Low Value Shipment (LVS) thresholds for all commercial importations (in addition to those for express shipments) to an estimated value for duty not exceeding CAD$3,300
The Proof of Origin of Imported Goods Regulations will be repealed for eligible goods claiming preferential treatment under all of Canada’s free trade agreements currently in force, in addition to CUSMA. Importers and owners of commercial goods, for which the estimated value for duty does not exceed the amount specified above, and for which the benefit of preferential treatment under a free trade agreement is claimed, will no longer be required to provide a (written) statement certifying that the goods are originating
The requirement on the importer to maintain records (e.g. commercial invoice, B3, etc…) applies even if the CBSA does not require a certification of origin or if a requirement for a certification of origin has been waived.
