I received visa correspondence letter after a week of approval, which i need to show to the immigration officers at the port of entry and visa printed in my passport. Study permit will be issued in canada at the port of entry. If that's what [visa correspondence letter] you are talking about. It will be posted in your cic account after a week of approval.
PS: You only need visa correspondence letter and visa printed in your passport. Along with may be the college offer letter and GIC copy.
