What documents are necessary for US citizens to return to Detroit from Canada?

Hello coachauburn-ga,

The best document to have would be a passport: "it is strongly
recommended that U.S. citizens also present their passports even when
returning from travel only to Canada or Mexico."

If a passport is not available, the following would work as well: 
-U.S. state or federal government-issued birth certificate or record
(note: hospital-issued birth certificates are not acceptable) or
baptismal record, Certificate of Citizenship, or Certificate of
Naturalization [note: notarized photocopies or notarized fax copies of
such certificates are acceptable, but affidavits of citizenship and
voter registrations are not)
-Photo identification document, like an unexpired driver's license or military ID.

happy to help you.
