At the time traces of cocaine were found on his bags and he was carrying $5,000 in cash. He provided his smartphone to border agents as requested, however refused to provide the password. Canada Border Services Agency officials asked for Philippon's smartphone and its password. From a report: "He handed over his BlackBerry but refused to disclose the code to access the phone. Philippon was arrested and charged under the federal Customs Act, accused of hindering or obstructing border officials." It is unclear if he provided the password while agreeing to the fine.
