In my opinion 800 over cutoff is very uncertain thing this year, as all the agencies are undergoing an overload of applications at the same time to meet with all CIC's requirements (WES,PNP programs,Ielts and LMIA program). If CIC's is expecting candidates with 800+ CRS scores,then the probability of that happening is very low. I believe they would have realized that in all their previous draws. The other issue they might be facing is too many candidates at a certain range of points (If they reduce the cutoff to 450,and there are around 2000 applicants within that range,then they will have a heavy overload). Monitoring all the forums so far I think the points for most applicants are ranging between 400 -450,so dropping the CRS scores anything below 420,will be a big leap for CIC,especially this year.
PNP programs update : BC stopped accepting applications,NL at least 6 months to process an application,AB stopped accepting application
WES program update : Claims 20 days, but actual processing time atleast 45-50days within Canada
Ielts program update : Most of the locations are fully booked atleast for 1-2months, since many applicants are retaking tests to improve their scores
