Lee Anne Raper is living the North American life along another border, the one that separates Canada and the U.S. A nurse at the Henry Ford Hospital close to downtown Detroit, Raper doesn’t live in Detroit. Actually, she doesn’t even live in the United States. For the past 19 years, she has driven to work every day across the Ambassador Bridge from her home in Windsor, Ontario, a trip of only about six miles.

“I can see where I live from the 17th story of the hospital,” she says. “I actually know some of the (border) guards. They call me by name and ask me if I’m going to work.”

Raper is just one of about 800 Canadian nurses who cross the border every day to work in the U.S. These border-hopping nurses highlight some of the similarities but also the differences between the economies of the two North American neighbors that share a 5,525-mile border and enjoy one of the world’s longest-standing and most amicable relationships.
