For the second time in less than a year, the City of Vancouver is floating the idea of two taxes that could calm Metro Vancouver's superheated housing market.

Finance Ministry officials have said the taxes might discourage foreign investment and undermine British Columbians trying to profit from the sale of their home.

Acting Vancouver mayor Raymond Louie says those fears are unfounded because 2016 assessments are up sharply and the average price of a detached home in the city has now topped 2.5-million dollars.

He believes the proposed taxes could help create more affordable housing.
