If TransCanada wanted to end the relationship with STWA they would have removed it from their installation and severed the relationship. That hasn't happened. Q.E.D. Any particular date isn't meaningful - it could be months. But if the AOT is moved, I'm guessing they will have to tell us. All evidence points to an ongoing relationship. Indeed we don't know what's going on - but I think it all points in a positive direction. According to the terms of the agreement, TransCanada was on Oct. 15 in default of the agreement for not honouring its terms. The fact that STWA does not appear to have invoked that default clause says they are still collaborating, probably closely. Evidently they can just leave the equipment there while figuring out the broader cooperation strategy. Anyway, whatever.
