$300k (USD) 1 bd room apartment in Yaletown, equivalent of this in SF is at least $750k. Plus property taxes in SF are around %1.15 for a $750k condo that comes down to 10k a year, just on property taxes. Not sure about the rules in Vancouver but the link I posted above claims $1,008 in property taxes. So yea I think Vancouver is affordable.
