Let's hope that it is an EU style border allowing Canucks and Yanks to move freely between border communities. I live in a border town, Ottawa, and can freely move between two different yet similar nation states, Quebec and Ontario. It is cool.
As a regular guy I can save money on premium gas, beer and groceries in Gatineau and not have to worry about delays at the border. Ditto Gat people who can fly across the bridges to take advantage of the better shopping and culture and hockey opportunities in Ontario.
If it, the perimeter, is like the EU it will allow our country to fufill the destiny that Sir Wilfrid Laurier envisioned for it, albeit a century later than he thought.
