A border wall would run down the middle of their street

The Canadian border became a U.S. presidential campaign topic when Wisconsin Governor and Republican hopeful Scott Walker responded to questions about the idea of building a wall between Canada and the U.S. by saying it was "a legitimate issue."

The suggestion received a lot of laughs online, as people took to Twitter and Facebook to comment on the idea. But the Walker campaign denied any interest in a wall, and released a statement saying "Despite the attempts of some to put words in his mouth, Governor Walker wasn't advocating for a wall along our northern border."

For their perspective on the Canadian-American divide, we spoke with people who live right on the border. Here are some voices from in and around the border towns of Stanstead, Quebec and Derby, Vermont, and a street with a name that honours both countries, called Canusa.
