Thank you.
Again, I understand that this is a bit of a hypothetical exercise, but let's say we separate the two aspects of this issue and set aside the questions around the necessity of the vaccine mandate at the borders. If we went back in time and didn't have the ArriveCAN app at airports, would the delays have been better or worse than what we saw using the app? I'm assuming that the border agents would have had to look at vaccine verification from all sorts of different countries, which in itself could potentially have caused delays.
Can you speculate a bit on what the situation would have looked like without the app but with the vaccine requirement?
