I had a report today of recent usage of runway 10 for a wide bodied jet. Upon closer examination, the X on runway 10 is in the displaced threshold whereas the X on runway 28 is on the runway. Based on this and the NavCan data, it appears to me that runway 28 is inoperative, but runway 10 is still available for rare use. In any case, the latest taxiway diagram shows it as a runway.
