Found this recent observation on an immigration lawyer's blog:
"For economic applicants who have pending applications for permanent residence filed before January 1, 2015, the processing of these applications may be further delayed and
take two or three times the processing time of those filed under Express Entry, as the government makes every effort to demonstrate that Express Entry is the best option for Canadian employers and prospective immigrants alike."
I just asked my own lawyer what to expect (I'm an Aug 2014 CEC applicant) and he estimates that 14-18 months may be the current time frame for those of us still waiting under CEC. Guessing that's not really what any of us wanted to hear.
