I rented an apartment in Florida and want to bring some of my belonging with me. everything I have is used and will be returned to Canada when I go back.
does anyone have an idea on the regulations about this?

and to go back to Canada:
go to google and get the document from the gov site called "moving back to Canada". I'd like to post it here but I get a blocking message. sorry!
