By rules it should be around 21 working days (stands for around 1 month).
When I put off papers at VFS, At that time I was quite ignorant of everything related to VFS and CHC, was told by VFS that I will get "Initial Response" with in 15 days. Oh! I was so happy, I thought with in 15 days I will get my visa and on 16th day I will be watching beautiful Air Hostess in Air Canada flight. but.....
ab sochta hun ki yaar Visa de do, wahi bahut hai ! Air Hostess nahi dekhni....
In short, if all of yours papers are in order, you will get visa with in 1 month.
