It looks like Canada is about to repeat the USA housing crisis of 2008. Loans for people who can't afford it! You gotta love idiots!

You aren't understanding the Canadian housing market at all. BC already put a huge tax on foreign buyers so if anything they've over cooled their market with intervention. It's in their best interest to have more local buyers. There will be no crisis, the demand for housing in our best cities is massive and getting stronger as the US loses favor as a destination of choice for many people.
People have been predicting a housing crash in Canada on here for many years. It's based on idiotic logic, that anything that appreciates a lot must crash ( we see this logic on numerous themes here from deluded traders ). In reality, Canada's major cities are not expensive compared to other world class cities in the world, including some in the US. And the demand is still extremely strong far greater then the supply.
The USA housing market was about loaning risky people a lot of money to buy a home. Canada isn't like that at all, our banks are conservative in nature, so much so that many legit buyers are essentially shut out of the ability to buy a home.
