Although illicit tunnels are not a big threat along the U.S.-Canada border, counterfeit visas are.
The Canadian Border Services Agency has issued a warning to officials of an increase of fake visas turning up at Pearson International Airport in Toronto. The carriers of the fake visas hail from Ukraine, Georgia, Azerbaijan and most recently India. The visas, which bear serial numbers starting with "A043283," are issued in Kiev and Chandigarh, India.
