The Canadian International Trade Tribunal decision in Frito-Lay v. President of the CBSA, AP-2010-002 (December 21, 2012), reasons January 8, 2013, teaches Canadian importers and the CBSA a number of important lessons. Three are of particular importance: (1) burden of proof, (2) jurisdiction of the CITT in cases of the President's failure to respond without delay to requests for further re-determination, and (3) limitation periods applicable to claims of NAFTA tariff preference.
