This administration has made it clear "securing" the borders is one of our nation's top priorities. In all honesty, the administration probably couldn't care less about the Canadian border. Almost all of its attention is focused on the southern border, but it also wants to make sure visitors/immigrants from certain countries are hassled extensively no matter where they first set foot in this country.

The nation's borders have long been a place where certain rights become privileges. Legislators and courts have done little to roll this back, usually favoring national security over individual rights. Border searches of electronic devices were already on the rise before Trump took office, jumping from 5,000 in 2015 to nearly 20,000 in 2016.
