It depends on several factors
1. Duration of cousre
2. Fee structure
3. Income certifications of sponsors
Assume ur fee is 18000 cad for 1 year and ur cousre is of 2 year.
U paid the gic, deposit to university and got loa.
U need to show 20000+ cad in bank account apart from that u need to prove ur sponsors are well established that they can afford the expenses by ITR Or any other income certifications for the second year too.
Hope it helps
