License to ship to Canada??

Just a note, I just sent out a package to the good ol U.S.A today and found its all changing. The expedited parcel form.. sticker is now Expedited Parcel U.S.A. .Its has a USPS Tracking # with a Canada post number .......A bit strange. The girl at the post said to me its not Us, its coustoms!!!!!!!!!!!!!!!weird.Canada post wants you to go on line and do your form, print it and then bring it to them so they can just scan it. Hell I just heard in Canada they want to do away with the postal courier and give all those dam boxes....WTF, its like a $1.00 just for a dam stamp...........
