Canadians are very easy going, bob. In fact, too easygoing according to some American officials.
And it has been that way for a long time now, even before 9/11. One of my Indian friends was telling me of his experience in the 60s, when he went on a bus tour of Niagara Falls (he was living in USA).
At the Canadian border, the Canadian official came on the bus, said good morning and proceeded to check everybody’s papers. At the end, he wished everybody a nice visit to the Falls and left, the whole process took just a few minutes.
Returning, at the border American officials made a pronouncement, everyone must get off the bus. There was a big melee as everybody crossed into the small immigration booth. There they checked everybody’s passports. It took more than half an hour.
Without going into detail, the experiences I related were while travelling on official business with the requisite paperwork to go with it in hand. I may go through customs several times in one day, and each time going South they take one person aside to check them. Years ago that was only done, if ever, when coming back into Canada because a few folks took liberties at the duty free store stateside, I just find it odd that the polarity has shifted.
