On September 14, 2017, Canada Border Services Agency (CBSA) issued Customs Notice 17-30 regarding the Canada-European Union Comprehensive Economic and Trade Agreement (CETA) that will go into effect on September 21, 2017.
The CBSA notice covers the implementation, tariff provisions, proof of origin, shipping requirements, refunds, updates, and additional information and provides several links for more in-depth information on the agreement. CETA will "essentially eliminate the customs duties on all imports from a European Union (EU) country or other CETA beneficiary, either immediately upon implementation of the agreement, or through a tariff phase-out."
