A soft landing for the housing market was always the Bank of Canada's mantra, even as housing prices, instead of heading for the landing strip, continued to soar into the stratosphere. Now, when Canadians' nerves are most likely to be rattled, it seems that our central bank has no reassurance to give. It has probably dawned on the members of the Governing Council that our housing market could be in for a crash landing, a bust to follow on the boom. If that happens Poloz and his acolytes must assume their share of the blame for it.
