You know, there was actually a newspaper article - I want to say, about 15 years ago now? About "illegal" Canadians in the USA, who were in the US on a combination of overstaying student visas, or just semipermanently staying in the US (in those days US Customs pretty much took you at your word if you said you were making a day trip and didn't bother to check up on you) and working under the table.

Considering many of us speak essentially the same language, albeit with dialectical differences, as English-speaking Americans do, it's not surprising that Canadians got (and still get) a pretty easy ride of it. :P
