Or something to do with entire condo projects sold first overseas in presales, apparently where demand is "unlimited".

A big shout out to the Federal government, both the present day Liberals and past Conservatives, for not placing any restrictions on the sale of our residential real estate overseas.  Unlike many other countries who do have limits.

And an extra big shout out to the BC Liberals, for not lobbying the Feds for restrictions. And of course for their first time buyers plan, which has no doubt just helped escalate price thus making even more homebuyers unable to qualify, despite the loan.

Well done gang.
