Don't get all wound up over Canada yet. All that international stuff changes daily. Our state dept. makes a change, another country counters with something else, then something doesn't work out, someone loses money and screams. Things are likely to go the other way. I think it will go down to the wire. I keep a passport anyhow, practically everyone in the world does, it is the universal ID. Here in the US folks haven't figured that out yet. Go to Sweden and try to get by with your drivers license, I guess that would be good for laughs!!!
Take care!
