No, i don't have a notarized statement. Maybe my parents can transfer me money to my canadian bank and then declare it as a deed of gift? Would that be a better option?You provide your fingerprints to the RCMP and they do the check.

Did you include a notarized statement from your mother confirming that you had full use and access to the funds? Even with such a letter, apps with joint accounts with people other than spouses have been refused. It is far better to have the funds in your own name only.
