Canadians can fly or even take a train here and have their car & stuff transported commercially. Only "personal" driving (or walking
) across the border is not allowed. Can't see that as being a terrible inconvenience other than some more expense but if they have a second home here I'm sure it won't bankrupt them (there are also quite a few here already down in Broward county where a friend lives in a condo). While it may stop some I'm guessing it won't be that many.
