Canada's meteoric fall from world tourism rankings

Canada was once the second most visited country in the world, only behind Italy, back when all planes crossing the Atlantic had to stop in Newfoundland.  But that ended in the 1970s, and today, as the world is going through a travel boom and more than a billion travelers crossed national boundaries around the planet last year, Canada has slipped to the 18th spot, trailing countries such as Ukraine and Saudi Arabia.
