Don’t worry !
College has given u time as there is much time in starting of jan intake.
Complete ur loan process and pay fees and GIC before October.
Aslo, if u want to be more sure to reserve ur seat than u can pay CAD $1500/- via Flywire to collage account.
Thenafter,
When u pay fees from laon. U required to pay Fees -1500 (Ex- 14600-1500 = 13100)
So, u have choice whether u pay full fees or first confirm seat & pay remaining fees later.
Anyways, People get more visas in month of october & november
