I don't think so they will consider into EE, who applied in 2014. Main reason behind that is Express Entry will function as a two-step process. Step one will involve candidates making an expression of interest in immigrating to Canada, with candidates who are eligible for one of the federal economic immigration programs entering the Express Entry pool. Step two will involve a portion of those candidates in the pool being issued invitations to apply for Canadian permanent residence.
According to EE process, I don't think so they will waive the first step for all who applied in 2014 and did not get AOR yet, Reason is in the mean time most of candidates PNP certification will be expired.
REST CIC knows better, We just assume
