Bunker C is a low end fuel used by ships all over the world including the Great Lakes. Some ships use unrefined heavy crude from Canada's oilsands. Very similar products but only one is hated by 
environmentalists.

Diesel and gasoline refined from oilsands crude in Edmonton is sent via pipelines to Vancouver, Calgary, and Winnipeg to fuel their vehicles and airplanes. (Vancouver & Calgary have their own spur pipelines running directly to the airport to keep up with the massive volumes needed for those large aircraft.)
