there is already a "travel ban" in effect for a lot of "Canadian born" Canadians. Anyone with a criminal record is unable to enter the states. A criminal record includes driving while intoxicated (impaired driving) and / or possession of marijuana. Any record at all can prevent you from traveling to the states. It is ludicrous that folks with a 25 or 30 year old record for DWI are prevented from vacationing in the US. On the other hand - just means those affected will travel to another nicer location !
