Can you cross the Ambassador Bridge into Canada without a passport? A friend of mine that use to live in Michigan is coming from Alabama to visit her dying grandmother. She said she knows she can get into Canada without a passport I told her I didn't think she could, she should get an Inhanced license. She told me they don't have them in Alabama and she's not worried about crossing, she already talked to customs...but they did tell her she may have a problem coming back. Why would they even let her in knowing there's a possibility she can't get back into the states?
