It's a nightmare for people trying to head into the United States right now.
The border waits are extreme, between two and three hours at all of the major crossings.
Zahra Premji is in the line-up at the truck crossing ....and she's been there for more than two hours.
"I think I see bright lights shining, which means we're getting closer to the duty free shop, so probably another hour and a half. We've been out here for over two hours. I heard that this is the worst anyone has seen in five years."
