Sigh... The annual Demographia study is mostly BS. First, they only look at a handful of Anglosphere countries and yet claim to cover the world; Second, they have strong ties to the automotive industry and have an agenda of urban sprawl -- this leads them to target negatively cities that are fighting sprawl, like Vancouver; Third, their only metric for affordability is housing price yet places where there is a more dense population often have high housing prices but lower overall affordability when all costs are considered, most importantly they don't include renting; Finally their numbers don't line with any other major reports (EIU, Mercer, etc).

While Vancouver, has the worst affordable city in Canada, it is very middle of the pack when you look at major cities in the world. And the notion that SF is more affordable than Vancouver is just laughable if you've lived in both places.
