You seem to be in lot of rush. Hold on and calm down first !
Try to understand that processing time of paper based applications are around 7 weeks.
You are yet to obtain GIC certificate, academic fees receipts, bank balance certificate and other statements. Even if you get these things done, it will be close to 20th July when you submit your application. I don't want to dishearten you, but this seems like a dream run to get visa in 30-40 days when many students are waiting for 3 months. On the other hand, when are you going to book your flight tickets and arrange accommodation in Canada and other misc tasks. You are trying to balance your act on a very tight rope at the last moment.
BTW, if your loan is from Avanse then ICICI is not going to give any declaration. They will probably give balance certificate. Documents related to loan has to come from right channel to convince VO. Otherwise your finance documents will get jumbled up between ICICI and Avanse and will confuse VO.
You should not have got loan amount transferred in one shot. Instead, the amount should have been released in installments as you progress semester by semester in your studies. I am afraid, now that you have got full amount transferred in one shot, the loan interest rate might have already started ticking. Unfortunately, paying GIC from loan was not advisable.
Usually, for visa you just need to show loan sanction letter. In the event of your visa getting rejected, you need not pay any interest to bank or loan issuing institution because you never took the real money from them. In your case, you have got 30L transferred and 5L paid for GIC, for God sake if something does not turn up as expected then how much interest you need to pay from your pocket now?
All this arrangement made in haste does not sound too good to me. My 2 cents - Try to get your admissions deferred to Jan 2019.
