CKVR too close to Toronto - it could be a goner unless they want to keep one secondary A station to cover all of Ontario. Some of the other A or soon to be abandoned CTV repeaters could be used to extend its reach.
That option is possible, but I think it more likely for it to become something like CHCH.
CHRO - too close to Toronto - it could be a goner although the studios could live on as CTV Ottawa after the CTV fire - secondary use would be to use it as a repeater or A-Ontario from Barrie
I assume you mean it is too close to Ottawa. CJOH is still running after the fire, they just moved studios so I doubt if CHRO would become Ottawa's CTV station.
It is likely wishful thinking on my part, but I would love to see it bought by either Rogers or Shaw and become a CITY or Global station for Ottawa, though since both have repeaters here, I don't see why either would do this.
CFPL could become a CTV affiliate
I think this is the best option for CFPL. London is a large enough market to support a local CTV station.
CHWI would be a goner as there is already a CTV repeater that sort of serves that area. There would probably be some rationalization of repeaters of CKCO and CFPL accross South Western Ontario.
They could make CHWI a CTV station and shut down the CTV repeater, but history has shown that CTV doesn't want to do this kind of thing (they shut down CKX-TV instead of CKYB-TV in Brandon, MB).
CIVI - would CTV want another CTV outlet for BC. Ironic that with all the past shuffles that CHEK which was once a CTV affiliate would see a competing station pick up the affiliation again.
Possible, but unlikely for CIVI to become a CTV station. With CHEK under private control, it is unlikely for CIVI to try the same thing. Sun could buy it to have a Western station, but they would likely have bought CHEK if that is what they wanted, though I could see CIVI being more attractive as it has a repeater in Vancouver.
At best I can only see one A station per province surviving with repeaters somewhat like Sun TV
Does Sun TV have a station outside of Ontario?
