Wow...never seen of "immigrant placement" fear before.  But, here it is! 
Scarcely 125 years ago, Canada did have such a policy, at least, as far as what we now would call "refugees" was concerned.  In fact, marketed the country on it throughout Europe ("Free land!  Come to Canada's vast western regions!")

If it mattered--and I'm of the opinion it really wouldn't--don't think it would affect Canada's "ranking."  

I'll go further.  I firmly believe that many immigrants and refugees SHOULD be directed to specific areas in the country for a certain period of time.  I'll go even further: if they want to move later, they have pass a Fed Govt. means test (self-sufficiency/productivity) in order to get the OK and--perhaps--citizenship, too. 

People: MILLIONS want to come here.  And that's today.  In the future?  MILLIONS more, as "civilized" life deteriorates elsewhere, at least, in their own minds.  How bad do they want it?  They'll sign on. And say "thank you Canada."
