Most international folks who want to move their money out of the country and into real property. This is particularly true of the Chinese and Vancouver, as the CCP basically owns all banks and can snap their fingers and make you poor. But they can't take land and houses in BC. Similar waves of buys have happened with Russians and a few after the new Saudi royalty started flexing their powers.

But it means a nice house in Vancouver (Kitsalano) goes for $2.4MM CAD while salaries lag behind the US. Even at US rates it would be dicey to buy a house unless you had a lump sum to hedge the risk of losing a job.
