Hi,
First of all, you do not have to submit any bank statements in EE application. You would have to submit these with many other documents after you are invited to apply to PR. When they invite you, you will have 90 days to collect the required documents.
Of course, submitting recent statements is required. Do not submit old ones it will definitely raise a flag.
Online isn't acceptable, it has to be stamped containing the bank letter head.
