I honestly don't think so. Eligibility is checked later on. My assumption (and I am too guessing) is that temp file number is generated when they opened your application package it is probably assigned to someone inside IRCC, AOR is probably generated when that officer checked your application and (probably) digitized it.From my assumption, they provide us with a Temp File # when they go through all the documents to verify if they meet all the guidelines and after that Officer send us an AOR after checking our Eligibility .That could be a reason for the wait between Temp # and AOR.Also people are getting COPR after an average of 4 months after AOR
