Yes, New candidates with french qualifications can be a factor..No not at all, none of the candidate who has Sibling in Canada or a francophone who were earlier in the pool got invite in this draw, the max a francophone who was earlier in the pool with 412 must be at 442 now and minimum crs candidate invited is 449.
All of candidates invited are people who either reentered the pool by rejecting earlier ITAs, or got rejected by IRCC due to some reason or new candidate with higher score than 449. Ofcourse any new candidate can have relative or a francophone or both.
