Unfortunately, Grundy has it backwards. The USA was a Canadian invention, where they shipped their insane and criminal because Australia was too far away and Canadians were too cheap. Oh, and the Acadians, but they were really sorry about that one.
Since then, Canadians have invented the phone, insulin, Java, basketball, cobalt bombs, zippers, wonderbra, electron microscopes, light bulbs (yes, even that) and other world shattering advances like the Crackberry. Unfortunately, when they shipped all the criminals to the south, Canadians forgot to search them and they managed to keep the keys to the side door in addition to money they'd already stolen. Since then, the pantry has been pilfered so often there's talk of Canada joining the USA as the 52nd to 83rd state (all larger than Texas), because they've stolen everything else anyway.
So the southerners have been stealing ever since - resources, well educated people, Avro Arrows, water, and so on. The Americans even invented Prohibition and used Canada to get even richer. So now Canadian inventors and actors have had to go south to get money for production, and get fleeced by the American criminals running their system. Meanwhile, Canadians staying here working for mostly American corporations have to settle for better beer and moose burgers.
