I'm in Vancouver. There's a population here that bought at the peak with 2.5% interest rates. When it comes time to refinance it will be painful or you will just be paying more in the long run. And if market value drops below your trigger, you will need to pony up the difference upon refinancing. Housing payments already account for 50%+ of people's household income. People are over leveraged on extremely heavy debt loads also. You add up all these factors and I'd say there might be a storm brewing.
