Fascinating human interest (and "political interest") story marred by hyperbole.  

"People seeking refugee status have been pouring over the Canada-U.S. border ..."  
Define: "have been pouring over" the border?  (Meaning, on foot.)  
"187 Americans requested to be admitted as refugees at Canadian land border crossings last year — more than double the previous total, according to Canada's border agency."  (Source, Global Post, Public Radio International)  In my mind, that hardly qualifies as "trickle."  The recent handful of those fleeing the US: don't even qualify as a "drip."

Also of interest:
