Quoting spookyb from another post -->I just got an email from CPP-Ottawa that they have my file. My ecas shows "application received"
http://www.canadavisa.com/canada-immigration-discussion-board/after-aor-file-is-still-at-ciosydney-additional-documents-where-to-send-t144977.15.html
So two conclusions
1) CIC does not inform when they transfer the file to CPP-O. In the above case, applicant asked so they confirmed.
2) By now the applications that reached Sydney till 15th-Feb, would have been transferred to CPP-O. This is based on the above case i.e. On 3rd-May, CPP-O had the application that reached Sydney on 12th-Feb.
