In Canada, there is no study visa such thing, to study in Canada you need study permit(to grant your status)+temporary residence visa(to be able to enter Canada)+CAQ(for study in quebec only)
here you can see study permit is under the category "temporary residence visa" : http://www.cic.gc.ca/english/information/times/temp.asp
And for your uci, you can find it on your study permit if you have one, it's printed as client ID(see more here:http://www.cic.gc.ca/english/helpcentre/answer.asp?q=013&t=4)
so if anyone got their study permit refused before, i'm afraid that he has to mention it in Schedule A, question 6 as Lammawitch said.
