How do I find my bank account number without checks or a statement?

I live in Canada and I have a CIBC checking account. I received a wire money transfer from my sister and needed to get it today (Saturday night) due to a personal reason. I miss typed the answer to my security twice because I forgot that caps lock was on and I had to reset my password, but in order to reset my password, I needed my Branch number and Account number. I currently have no access to the bank because 1) its midnight and 2) I am across the province on Vacation. What I'm asking is: How do I find my Bank account number without checks, bank statement OR access to the bank itself? This is Urgent and I need to know ASAP. Thanks in advance.
