@shabnum462 it doesn't matter which method you adopt for application because documents are same as per my understanding.
Even paper-based applications are submitted through VAC and later linked with an online system for updates.
Now I truly believe that It entirely depends on the mood of the visa office, even if your SOP is strong, the bank statement is huge, IELTS score (Although I got admission without IELTS), strong family connections, If visa officer has made up his mind then nobody can get a visa. It's only hope we are left with.
So let's hope for the best.
are you applying for the Winter-2019 session, it's getting late. Apply ASAP.
Good Luck
