Re-entering the country in YYZ in May I had trouble with the automated passport scanner. I tried to get it to scan my passport two or three times and kept getting an error message that said it wasn't a Canadian passport. Eventually, I gave up and went to a human immigration officer, which proved faster than the process for my two colleagues with whom I was travelling. Fast forward to last week. I arrived in YVR and thought I would just go straight to a human instead of using the infernal machines, but was prevented from doing so by three CBSA personnel and forced to use the machines. Yup: it said I didn't have a Canadian passport. So I looked for the way to the human agent and was waylaid by one of the three agents who suggested I try another machine. Same result, so he said I was probably doing it wrong. So he tried and got the same result. Then saying that the machines were a bit finicky he tried again and this time it worked. Next to insert the customs declaration card. This took three attempts before it was accepted! Finally I was able to exit the machine zone where I had to show my customs receipt to an agent, and answer questions about what I had brought with me. The whole process took at least twice as long as queuing for a human agent would have taken. Grrrrrrr Anyone else have these troubles? How do I avoid the machines in future and get to see a human straight away?
