Few of us here pointing out to the number of ITAs issued this year and thinking that IRCC setting a CRS cap above 430 and purposely holding it. No this is not correct! If you understand the economic category immigration system of Canada then you should know that eligibility criteria is not based on high CRS scores it is purely based on six selection factors where you need to score 67/100 points (age, education, work experience, whether you have a valid job offer, English and/or French language skills and adaptability (how well you’re likely to settle there)). If a person scores minimum 67 points then he/she is eligible to join the Express Entry pool. CRS score only ranks a person based on his/her selection factors, it does not make some one more or less eligible than others. Just ability to speak good English or French can boost someone's score by 50 to 100 points, does it mean who is a masters or phd holder with 10 years of experience is less eligible than one who got invitation with high language proficiency but only with a bachelor degree and one year of experience? Certainly not.
It is true that they want people who can easily cope in the vibrant Canadian society however they must have also know that a skillful person with moderate language ability can also be very handy for their economic growth. This is the reason they have set that six selection factor 100 points as eligibility criteria not that Comprehensive Ranking Systems Points. It is just the capacity of their system to handle application and new entrants that made them to set a annual immigration target and number of ITAs per draw. One more point- if Ontario consider and send NOI all people at or above 400 and IT professional below 400 (who is eligible on six selection factors) are eligible to live and work in Canada then how on earth IRCC would cap people based on CRS points?
This draw system is such that it slowly but certainly will decrease over the time and invite everyone who is eligible and got moderate language ability, if not all with minimum eligibility. CRS score is not a criteria to be invited, it is the 100 point selection points which is important here so this CRS cutoff point is bound to go down to 400 and below. Just be patience and let the bottle neck clear up above 420, it is coming down soon!
