Interesting note: I think it is a myth that one of the big five can refuse to open a personal bank acct for someone if their credit is bad.
FCAC regulations stipulate specifically when an account opening can be refused and bad credit / bankruptcy is not one of them. Instead:
When Can a Bank Refuse to Open a Personal Bank Account?
A bank can legitimately refuse to open a personal bank account for you if:
◆ the bank has reasonable grounds to believe that you'll use the account to break the law or commit fraud;
◆ you've committed a crime or fraud against a financial institution during
the past seven years;
◆ it has reasonable grounds to believe that you intentionally provided false
information when you opened the account;
◆ it has reasonable grounds to believe that opening the account would
expose its employees or customers to physical harm, harassment or
abuse;
◆ you do not agree to let the bank verify if the four circumstances
mentioned above may apply to you and to verify the pieces of
identification that you present to the bank; or
◆ you can't provide acceptable identification.

Doesn't apply to credit unions however. On this point I know personally.
