Between 2013 and 2015, Chinese citizens were caught with about $13.5 million in cash by customs officials at the airport. According to the documents the following amounts were seized each year:
- 2013 – $2.8 million
- 2014 – $4.3 million
- 2015 – $6.4 million
That amounted to more than 70 per cent of the $18.7 million of undeclared cash seized from all travellers, including Canadians, during that time at the airport. The reports did not say the number of people involved.
