Here is what IRCC has to say -
What we accept as proof
Funds must be readily available to you. For example, you can't use equity on real property as proof of settlement funds.
You also can’t borrow this money from another person. You must be able to use this money to pay the costs of living for your family (even if they aren’t coming with you).
If your spouse is coming with you, you can count money you have together in a joint account. You may be able to count money in an account under their name only, but you must prove you have access to the money.
The funds must be available both when you apply and when (if) we issue you a permanent resident visa. You must prove to an immigration officer that you can legally access the money to use here when you arrive.
For proof, you must get official letters from any banks or financial institutions where you’re keeping money.
Letter(s) must
- be printed on the financial institution’s letterhead
- include their contact information (address, telephone number and email address)
- include your name
- list outstanding debts such as credit card debts and loans
- include, for each current bank and investment account, the
- account numbers
- date each account was opened
- current balance of each account
- average balance for the past 6 months
