If you don't have a cheque
If you do NOT have a cheque, you can locate the account information you need in EasyWeb. Simply login, select the account you want to view, and then select the "Direct deposit form (PDF)" link in the upper right-hand corner. The form provides your account information in place of a voided cheque and is used when arranging for direct deposits or pre-authorized payments.
