As the title implies, an American moves up to Canada - and to his surprise, he discovers he's living in a foreign country! Amusing for me, since I grew up on the U.S. side of the Metro Detroit/Windsor area, as a fifth-generation American-born expatriot Canadian -- so, I have something of a different take on the joke about Americans knowing nothing about Canada (except maybe moose and Mounties, and Austin Powers); because, in Metro Detroit/Windsor/Toledo, we all grow up watching the CBC (avec l'exception des Michiganois(es), qui se grandisent à voir le SRC télévision).
Anyway, the gist of the series is that an American who knows nothing about Canada ends up learning a lot about Canada and, in the process, learns a lot about himself and the really important things in life.
As to the basic premise of American ignorance of Canada, I should say the matter is understated. Americans don't know much about ANYBODY, even other Americans. And it should be noted that Canadians do NOT know as much about Americans as they think they do. For example, Canadians often remark that one of the differences between the two countries is that Canada has two official languages whereas the United States has only one. In fact, the United States has NO official language, and the First and Tenth Amendments to the U.S. Constitution, together, probably forbid the U.S. Government from establishing one as power reserved to the several states. (In contrast to Canada, where all power not assigned to the provinces by the Canadian Constitution is reserved the federal government; all powers not assigned by the U.S. Constitution to the American federal government are reserved to the governments of the 50 states.) But I digress.
Most of the series after the first couple of episodes focuses on Jake Crew's burgeoning journey of self-discovery (to the extent one can pursue self-discovery in a sitcom - or in this case, a "Can-com"), and his slowly developing relationship with Judy.
Not great or rip-roaring fun, but a nice "Sunday-ish" bit of low comedy.
