I've got news for everyone, America already needs a second border wall!  How do you think Minnesota and Michigan fell to ISLAM???  The Conquering Muslims migrate to Canada, and that is just a stepping stone to the ultimate goal to go to THE GREAT SATAN, the USA.  The cross the borders without even passports.  THAT'S THE UN PLAN!!!  Send them all to Canada, KNOWING they won't stay in that cold climate, they will migrate on to the USA.
