I think those ships have sailed, though, with respect to converting them back to hotels unless the province intends to get into the hotel industry.
I also don't think supportive housing will be in the future what it is today, and any treatment/rehab facilities will be situated in different environments than within urban centres.
They'd be better off selling the properties as commercial development opportunities (the zoning is already there) and buying much more land/better facilities elsewhere (ie. in places zoned for long term care/hospital use/community centres).
