Did you satisfied all these requirements of OINP in previous submission.
Bank statements should include your name or your spouse or common-law partner’s name, account number, transit/institution number, account balance and currency. (As you are showing your FD amount so this is irrelevant)
If you provide bank statements in your spouse or common-law partner’s name, you must include a letter from the financial institution and/or your spouse or common-law partner indicating that you have access to these funds. (Irrelevant for you)
If your bank statements do not demonstrate a personal account standing/final balance that meets or exceeds the Low Income Cost-Offs (LICO), you may include proof of fixed term deposits, stocks, mutual funds, investments, and/or pensions, along with a confirmation that these funds can be immediately liquidated and at what value, and that they are free of debt or financial liability. (I think you provided the proof of your FD but failed to produce the letter from the Bank that this FD account can be liquidated at any time and they are free of any debt.)
In my opinion take a letter from your bank having all the requirement from the above last point and submit it again with your current FD amount proof.
