The United States Constitution

[billy]

The world needs a Canada that is sovereign and separate from the U.S.
All the old refugee trails out of the U.S. go north, to Canada.
Here in Calgary, where I live, we have 100,000 Americans in town who don't want to move back south.

i'd say thats par for the course where there's any long border. look at the mexicans in the usa. look at the eastern block countries in europe.

it won't make a country change sovereignty though.
