More than $1.2 million-worth of cannabis has been seized at the Calgary International Airport over the last year, according to Canadian Boarder Services (CBSA). That’s more than 160 kilograms (352 pounds) of the drug. The CBSA says most of the cannabis seized was destined for export. That includes 109 kg (240 lbs) intercepted in four separate instances where the drugs were found to be vacuum-sealed packages within suitcases destined for the United Kingdom. The CBSA says in each case, the travellers involved were arrested. Other highlights include the seizure of 12 kg (27 lbs) of cannabis in an otherwise empty suitcase on July 12, 18 kg (40 lbs) of cannabis in the suitcase of a traveller from Hong Kong on May 13, 32 kg (71 lbs) of cannabis from a Canadian citizen on a stopover from Vancouver on Oct. 27 and 48 kg (106 lbs) of cannabis concealed in bath towels within two suitcases of a Canadian citizen on Aug. 31. In Canada, it is illegal to import or export cannabis without a valid permit issued by the federal government.
