Does this mean that any subway with cross-over tracks is not grade-separated because of the possibility of opposite direction trains inadvertently occupying the same segment of track? Grade-separated means that the there is no unauthorized train traffic on the line so it can be fully managed. Once you open it to vehicular traffic, there is no assurance that they will not inadvertently cross gates - so it is no longer grade separated.But it's not fully grade-separated though. With full grade-separation comes both road and rail separations, this one doesn't have the latter. Look at the section through Etobicoke, surely that would limit it becoming anything beyond a 15min service. I'm down with using the term subway/metro when appropriate, but personally wouldn't in the UPX scenario.
If you look back, it did not say that Grade-separated is metro. It said that grade-separated, along with electrification and more frequent service, it basically considered a metro.
