Housing is seen as a huge part of Canadians' retirement planning. Politicians are afraid to do anything to lower the price of housing (remember Carney's housing minister saying they didn't want to reduce house prices?) because they think they'll be punished by voters. Because of that, house prices keep increasing.
It'd be great if there was a bi-partisan consensus to gently let the air out of the balloon by carefully lowering the amount of money available in mortgages, or the amount of money exempt from taxes on the sale of a primary residence. By all means, increase supply at the same time, but we also need to make homes less of an asset.
