Politicians have no clue that many Vancouver condo developments are not even being marketed in Vancouver, but rather straight to China.  Even houses being built, at least in Vancouver west side, are being marketed and built by Chinese corporations with a Vancouver office.  The workers are often exclusively mainland Chinese; you'd have to be beyond naive to think these workers are paying Canadian income tax.  (I've been walking past these construction sites for years and have googled a few of the companies with development applications for any given address.  My MP, Joyce Murray, must have done the same because she's got Chinese writing on her monthly pamphlets.  A slap in the face to immigrants, such as my parents and I, who struggled to learn English, to become part of Canadian society.)
