If you are applying for permanent residence in Canada, you must provide an official letter issued by your financial institution indicating your financial profile. This must:

list of all your bank (chequing and savings) and investment accounts, the account numbers, dates each account was opened and the balance of each account over the past six months,
list all outstanding debts, such as credit cards and loans,
be printed on the letterhead of the financial institution, and include your name and the contact information of the financial institution (address, telephone number and e-mail address).

请问

1. the balance of each account over the past six months, 是指账户中过去六个月的余额？
2. 银行的资信证明里没有显示过去六个月的余额，流水单里才有，按照IRCC这个要求是必须要提供流水单，而且要翻译？
3. 银行的资信证明里有银行的抬头，盖章，但没有提供银行的联系信息（地址，电话号码，email地址）这个会有很大影响吗？

谢谢
