Pre-Authorized Property Tax Payment Error

Yesterday evening, the City made an error in processing pre-authorized property tax payments. The June payment was correctly withdrawn on June 30. A second pre-authorized payment was processed in error on July 5. This has affected approximately 33,000 accounts.

As soon as City staff identified the error, on the morning of July 6, financial institutions were contacted to quickly resolve the issue. The reversal instructions have been processed and pre-authorized payment users should expect to have their money refunded beginning this evening or tomorrow. Time of reimbursement will differ depending on financial institution.

The City will reimburse anyone who has received non-sufficient fund charges due to this error. The City of London apologizes for any inconvenience this may have caused.

If you have any questions please call the City Property Tax Office at 519-661-4540 or email

UPDATE - July 11:

There has been a problem in processing the error correction file at Tangerine Bank. The error correction deposit has not yet been recorded in accounts of Tangerine Bank customers.

We are currently working with the City’s bank to resolve the problem. About 100 pre-authorized payment accounts appear to be affected.

The error correction file has been processed at all other financial institutions.
