I don't think you can compare the 2 markets without factoring in a bunch of issues like: immigration rates, vacancy rates, building codes, property taxes, landlord/tenant laws, financial regulation/ money laundering laws, environmental laws, government lending programs, etc... pretty much all of these factors favor higher housing prices in Canada. I can't comment whether the valuation should be 2 times higher but currently there is definitely a supply/demand imbalance for housing in Canada.
