Who here is a Canadian? Cuz most of you seem to be from a different Confederation than me.
@Duchie: IIRC, actually, it was largely the Canadas (ie, Ontario and Quebec) that were behind confederation. Despite how much they complain nowadays, Quebec was largely in favour in 1867. Nova Scotia was actually vehemently opposed, was brought in largely by the efforts of its Premier, Charles Tupper, and had a small but vocal separatist movement for the first decade or so.
As mentioned above, PEI didn't join until its attempt to build a railroad (across an island not even 200km across! Jeez!) bankrupted it, and ditto for BC (and for Newfoundland 80 years later). However, the odds of any of them wanting to join the states is pretty much nonexistent: Confederation came about, at least in part, to keep the States from moving north, and everyone was more or less a contented british subject (even, at that time, the Quebecois).
