City of St. Catharines Supplier Update Form

Please make any required edits on the following supplier form. Please note, some fields are mandatory for verification purposes.

For some changes you may need:

  • Your GST / HST registration number
  • Enrollment in electronic funds transfer (EFT) is the preferred method of payment. If you are a Canadian supplier wishing to change your banking information, please have your financial information ready for submission. A signed bank letter with the bank name and address stamp affixed is necessary to enrol in EFT payments. If you cannot obtain a bank-stamped letter, please upload a PDF or JPEG copy of a MICR-encoded void cheque. Please note that direct deposit forms are not accepted.
  • Any suppliers that are from the U.S., or any other country exluding Canada, wishing to update your banking details, please have complete financial information, including your ABA number or SWIFT Code prepared.

If you have questions, or need support, email suppliers@stcatharines.ca
