If the agency believed that such examinations were not worthwhile, we would stop doing them. Unfortunately, we find child pornography and propaganda material on phones. In addition, in the case of people who said that they have not acquired anything on their trips, we find receipts on their phones that show otherwise. That examination is valid.
As I mentioned, we only do it for the purposes of the Customs Act. It is important to stress this. I would not say it is used as a last resort, but the fact is that a traveller's cellphone is not the first place we search. We start by asking questions and searching the luggage. Then, if something suggests an offence under the law, we can go so far as to search the telephone. We do not do it systematically. Unfortunately, I cannot give you statistics on that, but it is a very low percentage.
