I am from Pakistan and opening GIC account, how long it should be in Canada? for 60 or 90 days or it does not matter? and Can my brother transfer the money into my GIC account or it should be transferred from Pakistan?
I don't understand what you mean by keeping it there. GIC account is locked for one year. When the Canadian bank receives the money, they will send you details and a letter confirming the account and the $10,000. That is the proof you need to upload in your application, and show the CBSA officer on entry into Canada. Go to the bank physically with that letter and your study permit after you land in Canada, and they will finish setting up the account and give you a debit card. They'll release the funds accordingly.
