Thank you.
With regard to Mr. Cullen's point, I would note that if I saved documents on my Google Drive and I don't have the Google Drive application on my phone, I can certainly cross the border. No one is going to search my Google Drive, and I can access it in the U.S. You'd have to delete it from your phone.
I just have a few questions. First, I take it that you are referring to CBSA bulletin PRG-2015-31. It refers to the Customs Act and to IRPA, and it sets out policy prescription for the CBSA officials with respect to the searches of electronic devices.
