Hi,
This should be mentioned in the request letter. For my case they asked for 3 months bank statements for checking (savings) account.
-You should send three months bank statement for checking account.
-You can also send latest certificate from bank for your fixed deposit including copy of deposit advice to show that you are still owner of those fixed deposit
In think " Proof of" means you need to proof SINP that you are still holding minimum same of fund that you showed during application (January 2, 2014).
In the application guide it is mentioned-
"In your application you are required to submit detailed documentation to verify three
consecutive months of stable funds prior to application to the SINP, including a detailed
history of funds. These funds must meet requirements throughout the entire immigration
process. Acceptable funds include those from the following sources only: Checking
accounts; Savings accounts; GIC; Mutual Funds; RRSP; TFSA; Term Deposits; Time
Deposits.
Please note that the settlement funds must be in the principal applicant and/ or spouse’s
name."
