Which country(s) other than the US were the most problematic / worst? Personally I've had more aggravation at the Canadian border than any European country.
Many countries are worse to deal with than the US at the border during entry. Ironically, most of the worst ones are wealthy / "low corruption" countries, because they have well-paid, interested people at the border, who also don't like having their authority challenged in any way. The UK and Canada are both significantly worse to deal with than the US, probably my worst experience on entry though was Australia. IMO,…
I agree, Canada's border crossing is worse.
I've crossed the US with underage children without their mother present several times.
US customs hauled the kids out of the car and took them to a secure location and asked them where they are going, if their mother knows where they are, etc.
This makes perfect sense and I'm glad the US customs officers took the time to do this. They are doing their job, preventing child abductions, etc and it was outstanding to see it being done.
Entering Canada it seems they only care about one thing : What do you have they can tax you on.
I wont be surprised to see the day when Canada measures how much gas is in your car, and if it exceeds an arbitrary amount tax you on this too.
