Canada is not a dumping ground for Trump's toxic policies. 
Canada-U.S. has an agreement where all refugees in U.S. must be processed in U.S. (and vice verse). We cannot and will not accept such refugee 'dumping'. 
All of them must be returned to the U.S. for the Trump authority to handle. We should demand U.S. border service enforce the agreement by monitoring and preventing their refugees from crossing the border into Canada.
Or we will build a wall. And make Trump pay for it.
