I deleted and re-created my Express Entry profile today to be considered for Ontario PNP.
When I was creating the profile, I selected "All provinces and territories" and I was given an additional option to select: whether I consent to share my data with Ontario government. There was no such option when I was creating my first profile in the beginning of the year. So I think that CIC only added this option recently, and only if someone selects "Yes" for this option, can be considered for Ontario PNP. So older profiles, where there was no possibility to allow sharing the profile data with Ontario, could not be considered by the province because the profile owner could not agree to share the profile data.
