Cokers are the key to Canadian heavies (Cold Lake, Lloydminster, etc). I noticed that three new units were coming on line besides the upgrade/expansion of existing cokers. One was at Cenex/Laurel, a small refinery, but significant when you consider its a coop and a new coker is quite expensive.

I am not as versed with Canadian or heavy oil refining as I should be. As you know most US refineries have used strictly light crude. I will brush up. But not so long ago I can remember shutting in sour oil and walking away because their was no market. Hopefully shale oil production can be increased to a million barrels a day in the near future. That would off set the declining production of light crude.
