Canadians can’t enter Canada from the U.S. in a rental car. Reason? Unknown.
According to an Ottawa Citizen report, Magill’s European vacation last year hit quite the road bump in Canada because of a bizarre federal regulation that nobody can explain – including two members of Prime Minister Stephen Harper’s cabinet.

All Magill wants to know is this: why can’t a Canadian drive a U.S. rental car into Canada? [[Interestingly, the law doesn’t apply the other way around: an American is permitted to drive a Canadian rental car into the U.S.)

Incredibly, Magill has been making inquiries for the past year trying to get an explanation for the rule....
If anyone can solve this mystery, surely they must be a member of DetroitYES. So what's the rationale for this rule?
