It does not apply to those who applied before November 2013.You are OK.The reason is there is some intense inspection for those cancelled NOC codes hence the cancellation.A lot of people were faking the positions and as you know there are coworkers who will report the fraud.cic call center "press 5 for immigration fraud
".
I see that they are becoming strict towards restaurant supervisors and cooks. i don't know if the VO's are strict towards your NOC.
What might be a problem for many of us is that; remember many applicants have families and the visa's given to each member counts towards the CEC per year visa limit.I cannot remember the actual limit figure.
