The developers hire temporary foreign workers, barely build to code and then pair up with real estate agents that are not qualified "economists" to make up a new price severely inflated beyond recognition. 

The real estate agencies also have satellite offices in China, they then contact that office for the next "investor". 

When I was growing up, anyone referring to housing as an "investment" were shunned immediately, and automatically considered a fraud artist. The governments having dinners with these "investors" clearly have lost their mandate focus to protect the future of Canadians, not protect foreign investors.
