There may not even be statistics - Canada doesn't have any comprehensive foreign demand data - that accounts for multi-unit demands for recent immigrants (now citizens or PR) acting as proxy buyers for third parties to evade taxes, and various other reporting gaps that exist. So it mostly comes down to relative wealth & population sizes versus desirability of an area, and then spillover effects into surrounding areas. But unless China crashes I would expect this to be an increasing source of demand over time, especially if you live in a pro-immigration country that needs to paper over domestic government budget shortfalls.
