One way tunnel? One city, two countries but snapshots of the entrance of the Detroit-Windsor tunnel underlines the interdependency of the two countries and particularly an almost one-sided supply of labor from Windsor to Detroit. Does anyone know the numbers of that? I believe I heard that over 5000 Canadians work in Detroit.

Below: It's after 5PM on a weekday afternoon and a Canada-bound traffic jam forms at the entrance to the Detroit-Windsor tunnel. Minimal incoming traffic is seen entering the US at the top.


At 8:30 AM an opposite story appears.
