Although I don't know the details of the process Toronto Conference is using, it's possible (as Gord suggested above) that there are other parts of the process still to happen aside from one interview with Greta, and in any case I highly doubt that there's been a decision made yet. It's not a simple "yes or no, in or out" decision. There are a variety of possibilities in between.
Were I in charge of the thing (I'm not - phew!) I'd release a decision allowing her to stay in the pulpit pending completion of a course of study on United Church doctrine, United Church history, United Church polity and pastoral skills. The first three because Greta hasn't demonstrated a grasp of any of that in her public comments, the fourth because of the way the West Hill split seems to have been handled pastorally - which is to say that Greta doesn't seem to have acted very pastorally in her attitude toward those who disagreed with her. After completion of those courses, I'd require a second interview with her.
If Greta refused to do the required course of study, then she'd be demonstrating an unwillingness to abide by the discipline of the church, which would make her more subject to removal - but it would be her decision.
A colleague suggested recently (and I'm sympathetic to this) that if she's removed then the congregation (probably unwilling to stay in the UCC without her anyway) should be given the option of simply taking the building and continuing on as a Community Church - or at the very least renting the building for a nominal fee.
