Thank you for your advice.
I didn't think CSIS might not have sent the advice to CBSA, but after reading your comment now I have strong feeling that they didn't.
As per your advice, I requested CBSA report again yesterday with CSIS letter attached.
I ordered CSIS report on Aug 3,2017 and received the letter Sep 12,2017. It says they received SS request from IRCC on Aug 31,2016 and it was completed and advice was sent on Dec 30,2016.
But when I contacted IRCC they didn't have any idea it was completed, nor GCMS note mentions either.
What I've done so far, I sent the CSIS letter to IRCC and CBSA.
IRCC has no updates yet.
We'll see what happens.
