I’ll be applying for my bachelor program ..but has one doubt about that my close relatives are living in Canada so because of this are their any chances that my visa will be rejected?
They should not have an impact. Also in the family information form, you would need to put information only for your parents and siblings.
I would recommend that in your Statement of Purpose, you need to clearly mention that you will be returning back to your country after you finish your program in Canada. It is important to show ties in your homeland. For example, a job offer letter, taking part in your parents business, your family back home, your properties or your parents properties, etc etc.
