If you are PGWP holder and meet the minimum requirements for CEC, then fill out the EE profile ASAP and stop worrying about PN and LMIA points. You will be invited to apply under CEC stream, not FSW or FTP, so you won't have to compete with applicants in those streams in which getting an LMIA or PN is easier/required; the only bad thing is that we PGWP holders with no LMIA or PN are gonna have to wait, and because the system is new, we don't know for how long (That's why it's important to get on EE fast!).
CIC has already had one drawing in which 849 of those picked where all exclusively CEC applicants, so out of 3,594 general applicants who have recieved ITA as of March 19th, at least 24% are CEC applicants, and even then that percentage fails to consider that CEC applicants probably got chosen in "non program specific" drawings as well. While non-specific drawings might end up with higher CRS cut-off marks (The latest drawing had the cutoff mark at 735 (Wouldn't surprise me if that ends up being the minimum cutoff mark this year)), I am pretty sure that any subsequent CEC-specific drawing (Which I'm pretty sure will happen) will have CRS cutoff scores be as low as 360 (My guesstimate is that 360 will be the minimum cutoff mark for CEC this year). My advice to anyone who is a concerned PGWP holder is: If you are eligible for PR under CEC get in EE pool ASAP!! While more CEC-specific drawings are bound to happened, I am pretty sure that these will be few and spread out far in between, so you don't want to be out of the pool for when these CEC-specific drawings happen.
