There's a good chance you've never heard of Line 9. It's an oil pipeline that runs just north of the 401, and parallel to it, including in eastern Ontario. Enbridge would like to reverse the flow of that pipeline and increase its capacity, to carry crude oil from the Alberta oilsands to refineries in Montreal. The plan has its critics, however - including people concerned about the potential for a major spill. The CBC's Kate Porter talked to Alan about the Line 9 controversy.
