How does a scholarship/bursary verify that you come from a low income household?

Many scholarships or bursaries may ask you to self-identify as coming from a low income household if your family earns less that the amount they state. To verify this information, they may ask you to share information from your previous year’s taxes and T4s to prove your income status. Some may instead ask you to share documents from your provincial student aid organization — like OSAP, StudentAidBC, etc.
