Thanks for link, I'll read the article and browse the blog mentioned, could be interesting pieces. I don't think I'll look at the story comments, other people's snap judgement negative views (often mix of ignorance and jealousy) aren't of much interest to me.
On property prices, I don't know about any Canadian markets, no specific interest in those, but sounds maybe similar to London UK where typical prices have also been pushed up by foreign investment. A couple of general points though:
First of all, I would rather we went back to a world thinking of their primary residence as a place to live and a home rather than another investment vehicle i.e. housing value should be the cost to build it (spread over the 100+ year lifetime of a property) and maintain it i.e. not too high, rather than the "investment value". So I would much rather, and think it would be better for a lot of lower and middle income households, if property prices were much lower than they are in the UK, these parts of Canada mentioned etc. (I'm not saying a big crash would be good, it would have been better if prices had not gone up more than salaries. So as can't change the past it would be better in future if house prices remained flat for a while and only then went up at no more than salaries. And I mean salaries of low and middle earners, not average or top salaries inflated by the top 1%).
Second of all: if you do think property is a good investment (I agree over medium/long term that property and rents should be a good and relatively stable return. I mean better than cash and gilts/treasury bills, perhaps a bit less volatile and a bit lower return than equity), then you can do it through a property fund (I own no property but have a reasonable amount of money in a property fund). That way you have the property investment exposure, you are more diversified and crucially, its value or fluctuations don't affect the roof over your head etc. And if you really think property is a good investment yet only own a smaller/lower value property, you can gain some leverage by keeping a mortgage on the smaller place and having the capital in the property fund too (I don't do this and would only think it advisable for those with higher incomes or other savings i.e. a risk not worth taking for those with lower net worth).
