Is it mandatory to provide my current CTC (cost to company) or salary details for the application?

No, you are not required to provide your current CTC (cost to company) or salary details when applying for a Canadian study permit.

The main requirement is to show you have enough funds for tuition, living expenses, and travel. This is usually done with documents like bank statements, a Guaranteed Investment Certificate (GIC), proof of student loan, or a sponsor letter.

If your employment is funding your studies, submitting salary details and employment proof can help demonstrate financial stability, but it is not mandatory.
