(CNN) — The Canadian government is warning citizens visiting the United States that US border officials have the authority to search travelers’ electronic devices – including phones, laptops, and tablets – without providing a reason.
In a revised travel advisory posted online, it urges Canadians to “expect scrutiny” when crossing the border and warns that refusing to comply involves risks including device seizure, travel delays, or the denial of entry for non-US citizens.
Under US law, Customs and Border Protection (CBP) agents may demand passwords to unlock devices during inspections. Travelers who refuse the demand risk having their electronics confiscated and may face long delays.
The advisory recommends placing devices in airplane mode before crossing to prevent unintended downloads of remote files, which could complicate screenings.
The move follows recent incidents involving such searches. Last month, Dr. Rasha Alawieh, a Lebanese assistant professor and physician at Brown University, was deported to Lebanon after US agents at Boston Logan International Airport discovered deleted photos of the late Hezbollah leader Hassan Nasrallah and Iran’s Supreme Leader Ayatollah Ali Khamenei on her phone.
The existence of the photos was outlined in a court filing obtained by CNN affiliate WCVB.
“In explaining why these multiple photos were deleted by her one to two days before she arrived at Logan Airport, Dr. Alawieh stated that she did not want to give authorities the perception that she supports Hezbollah and the Ayatollah politically or militarily,” the filing reads, per WCVB.
While US authorities maintain that device searches are critical for national security, civil liberties groups have long criticized the practice as invasive.
The US Supreme Court has upheld the authority of border agents to conduct warrantless device searches, citing the “border search exception” to the Fourth Amendment.
