請幫忙.剛收到CANADA的體檢通知,同時要求補文件,其一是

原文如下: Current statement of funds already in Canada or available to be transferred to Canada, i.e. letter(s) from your financial institution(bank) confirming the type(s) and current balance(s) of the account(s) you hold. Include bank statements fron Canadian banks if applicable.
這是要什麽文件呢?是否我一定要在CANADA的銀行有帳戶和存款,在美國銀行的行嗎?其實我們在申請時已提供了在美國的銀行存款證明.
多謝熱心人回貼.
