Well, I doubt this assertion because my eligibility is showing as completed in the tracker, and when I called the next day to check, my security check had not started until then..... I am unsure whether its by default that the security check starts right after eligibility is passed or some other way. IRCC has its own way of doing thingsAt times, when there is recommended passed they already initiate your security, however, it all depends on the visa officer. May be your one is already out of office due to holidays. Just be patient and you'll surely hear something by first/second week of January!
