Newly released documents show Nexus travellers who are supposed to be low-risk have been caught trying to smuggle goods into the country illegally. The federal government says the program makes border patrol more efficient by allowing border guards to move Nexus members who have already undergone security clearances to pass through customs more quickly. But documents obtained under the Access to Information Act show more than a hundred Nexus travellers were caught smuggling goods valued in the thousands of dollars in the second half of 2010.
