Agreed, like a doube edge sword.  These newly minted citizens are buying up the available inventory 
inflating the prices and in alot of cases not contributing to the local economy, workwise.  
Case in point GAR385, in my small albeit very desirable city of Burlington, my new neighbour is from China via Toronto, is married though have never seen her husband, does not work, unless it is from 
home, and has been away since mid Dec, presumably back home.

The couple who lived there before were both PHD/s. One working locally and the other working down the hwy in Niagara...opposite to Toronto!!  They moved to Niagara to be closer to ones work while the other had retired.  Replaced by a phathom worker that not only took a good house off the market for a worker but paid a ridiculous price to add fuel to the already egregious market that we are experiencing.

So there, signed sealed and delivered.....proof in the pudding.
