@Lorin K.Although Vancouver is ranked third least affordable in this year's Demographia report; yielding second place to Sidney, Australia, its median multiple {housing price to income ratio} rose from 10.6 to 10.8 meaning things became even less affordable.While foreign investment is a big driver in the frothy Vancouver housing market, it's not the only factor at play.On a national level , Canada held onto the dubious honour of being second on the list of countries where housing is least affordable - the median market remained flat nationally, but improved slightly when just the major metropolitan centres are considered.Toronto - Canada's second most foamy market - saw its median multiple rise from 6.5 to 6.7 - ranking it 330th out of 367 cities in order of decreasing affordability.
