In the GCMS notes under assessments you will see:Ibaadat said:how can you tell security is started from gcms notes. can you kindly help in detail or paste relevant section from your gcms after hiding your personal info. I will really appreciate.
Eligibility: passed
Security: (its blank they don't say its in progress)
Criminality: passed
Medical : passed
So these are the main stages your application goes through during processing, i assume since i passed criminality, medical, and eligibility there is only security left which is the background check
Other way u can know your background check started is as our friend PKforever said When you login to you GCKey's under the Background Check it will say " in progress "
Also i emailed the embassy in August 2016 about updates and they said that my application is undergoing security verifications conducted by the CBSA and that they can't give me a time frame.
