Is it, I never heard before, Thank you a lot for sharing..Three of my colleagues/friends received similar emails prior to getting PR. It looks like in some cases they don't send PPR emails to CEC inland applicants, instead invite them for 10-20 min friendly interview (according to my friends ) and after that issue CORP to you right away.
Next week have interview in Etobicoke.
Hoping for some good news.!!
