Eddie Francis says his office has contacted the office of Detroit's emergency manager.
It's not clear yet if Detroit's portion of the tunnel is one of the city's assets that would be put up for sale.
Though the bankruptcy had been feared for months, when Detroit filed for Chapter 9 on Thursday it became the largest U.S. city in history to do so.
While Francis believes Detroit's bankruptcy won't impact other relationships between the two communities, he says one of the key questions is what happens to the U.S. section of tunnel.
Currently that portion is owned by the City of Detroit but it's leased to a private corporation for the next seven years.
Note to readers: This is a corrected story. A previous version said Windsor was looking to purchase the U.S. portion of the tunnel.
