I can't see them doing that (they are short on housing now as it is. And with the CP getting more popular every year, they will need all the housing they can get). I know they are redoing apartments. But I doubt they will knock Vista down.
Doubtful. As of late they have been doing a bunch of roof repairs to various buildings at Vista Way. These of course could just just duct tape and bailing wire repairs to get them to a certain date but it is still pretty unlikely that they would repair buildings only to demolish them.
