Housing prices in two of our larger cities (Vancouver and Toronto) are also crazy high (eg $1M to buy a starter home)...actually in Vancouver proper at the moment the cheapest home (single family, not strata) is $1.2M...surprisingly (to me) in Toronto the cheapest home on the market is $650K (ignoring some listed for $1 as clearly there is a catch).Our mortgages work differently than in the US, and what we get for rates are only locked in for 1-5 years (typically) and then we have to renew at whatever the current rates are.
