Let me preface this by saying that I am not in need of this information personally nor am i personally in any trouble. I have spoken with several maritime attorneys and no one knows for sure.
Does anyone know with any absolution by your own experience or by the experience of someone close if: If an American citizen can enter Canada if they have a DUI on their record? If there are any special accommodations or visas needed? Or fines to pay? Google is all over the map on this one.
