He writes: "We all sense at some level that things are out of control, but nobody knows what to do. Hey, how about lashing out against those shadowy “foreign buyers,” even before we have the evidence to know they are to blame?".

Actually, plenty of people know what to do. But you, sir, are part of the problem, invoking as you do the ridiculous phrase "shadowy foreign buyers".

No, it is not "foreign buyers" high on the list for people who pay attention to Toronto and Vancouver. 

What IS high on the list are Canada's immigration policies. You see, sir, rich new immigrants are not "foreign buyers". You raise straw-man nonsense with your words.

The Quebec investor immigrant program is creating the better part of ten thousand new ultra-rich immigrants a year, who then buy in Vancouver and Toronto. Prior to it, the federal program created hundreds of thousands.

You want evidence how fast they can shoot tiny bungalows up to cost two million a pop? Visit Vancouver.

Ever been there, sir?
