Totally agree and while some of these may be legitimate rejected refugees from the US most are not rather they are economic migrants.   This trickle will soon become a flood when the human smugglers realize there is a ton of money to be made by providing an organized route north into Canada I suspect all the way from Mexico to our border.

And amongst those economic migrants it is entirely possible that a few ISIS sympathizers will walk in but not report to the RCMP.  You can be sure that ISIS is reading these reports of easy entry into Canada as we speak.
