`...the population hasn't risen dramatically.` Hmm.  I got figures  from in- and out-migration, Metro Van.  About 25,000 net (that`s additional) people come to live in Metro Vancouver on average, every year.  That`s a small town every couple of years.  

`...there is an "unlimited" pipeline of foreign capital ..."  Unlimited? Not so.  In January, China severely tightened up requirements to stem the flow of fleeing capital.  Specifically targeted: money purchasing overseas real estate.  Limits were severely lowered, which means, if anything, Chinese foreign buyers (MOST foreign buyers in B.C., by a long stretch) are now buying condos.  This--not the 15% tax--is what has drastically lowered foreign buyer numbers since New Years. 

How BIG, how SERIOUS is the foreign buyer `problem`? Van. Sun, March 27: Last month, foreign nationals accounted for about $93 million in residential sales in the region, or a little more than three per cent of both the value and number of all transactions.
