IRCC can be adjusting to normal processing time, but that should mean impact on all categories. How can CIC FSW are getting affected but PNP has been kept out of radar ! One logical explanation can be of quota, assuming that post BIL a person still have a chance to get COPR in 30 days, IRCC might not be willing to take the risk and omitted processing FSW cases in Nov. PNP quotas are seperate than the Federal ones. So they are fast tracking them in this to optimize the time. Just a thought.
If some one misses or deletes the BIL request mail then he/she should still be able to access it through GC key. Assuming people checks the GC key, I was saying that it is rare that one does not notices BIL request.
