If Trudeau keeps flooding Canada with muslim immigrants for their votes in 2019, POTUS Trump will likely harden the border between the USA and Canada in fear of the terrorist element in N. America.  And once in Canada, they cannot be sent back to their home countries.  
Canadian immigration policies will clash with American immigration policies, and we know who will win.  Canadian nationalism will cost us money, jobs and security if we continue on our current path.... believe it.
