ALL of the Canadian tarsands are refined in the free trade zone and shipped overseas. It's an export pipeline. Canada should build their own refinery and pipe that sludge to their coast.Across Canada to where? The oil was going to our refineries that are able to process these tar sand oils. From there we were going to use some and ship some out. The oil is going over the US no matter what. But it's much safer to pump the oil than it is to have it run across our country in tanker cars on trains.
